Abstract As the range of handheld, mobile and desktop devices expands and worldwide demand for collaborative application tools increases, there is a growing need for higher speed impromptu cross-device application sharing to keep up with workplace requirements for on-site or remote collaborations. To address this, we have developed CamCutter, a cross-device interaction technique enabling a user to quickly select and share an application running on another screen using the camera of a handheld device. This technique can accurately identify the targeted application on a display using our adapted computer vision algorithm, system architecture and software implementation, allowing impromptu real-time and synchronized application sharing between devices. For desktop and meeting room set-ups, we performed a technical evaluation, measuring accuracy and speed of migration. For a single-user reading task and a collaborative composition task, we carried out a user study comparing our technique with commercial screen sharing applications. The results of this study showed both higher performance and preference for our system. Finally, we discuss CamCutter’s limitations and present insights for future vision-based cross-device application sharing.

The use of mobile devices, especially smartphones, has become popular in recent years. There is an increasing need for cross-device interaction techniques that seamlessly integrate mobile devices and large display devices together. This paper develops a novel cross-device cursor position system that maps a mobile device’s movement on a flat surface to a cursor’s movement on a large display. The system allows a user to directly manipulate objects on a large display device through a mobile device and supports seamless cross-device data sharing without physical distance restrictions. To achieve this, we utilize sound localization to initialize the mobile device position as the starting location of a cursor on the large screen. Then, the mobile device’s movement is detected through an accelerometer and is accordingly translated to the cursor’s movement on the large display using machine learning models. In total, 63 features and 10 classifiers were employed to construct the machine learning models for movement detection. The evaluation results have demonstrated that three classifiers, in particular, gradient boosting, linear discriminant analysis (LDA), and naïve Bayes, are suitable for detecting the movement of a mobile device.

In this paper, a novel plasmonic band-pass filter by using the system consisting four waveguides and an asymmetric cross-shaped resonator is proposed. The plasmonic system is based on the metal–insulator–metal (MIM) structure which could overcome the diffraction limit and exhibit various promising applications. Here, we investigate the transmission spectra of the cross-shaped resonator by using finite-different-time-domain (FDTD) method and we find that the peak-wavelength on different ports show redshift or blueshift behaviors which are linearly changed with the length of cavity or the coupling distance. Moreover, the wavelength filter could be achieved and further applied in optical signal integrated circuits.

Abstract With more and more users using different devices, such as personal computers, iPads, and smartphones, they can access OPAC (online public access catalog) services and other digital library services in different contexts. This leads to the phenomenon that user’s behavior can be transferred to different devices, which leads to the richness and diversity of user’s behavior data in digital libraries. A large number of user data challenge digital libraries to analyze user’s behavior, such as search preferences and borrowing habits. In this study, we study the user’s cross-device transition behavior when using OPAC. Based on the large-scale OPAC transaction log, the online activities between device transitions in the process of using OPAC are studied. In order to predict the follow-up activities that users may take, and the next device that users may use, we detect features from several perspectives and analyze the feature importance. We find that the activity and time interval on the first device are more important for predicting the user’s next activity and the next device. In addition, features of operating system help to better predict the next device. The next device used is more likely to predict the next activity after the device transition. This study examines the cross-device transition prediction in library OPAC, which can help libraries provide smart services for users when accessing OPAC on different devices.

Many human activities now take place in settings that include several computational devices—such as desktop computers, laptops, and mobile phones—in the same physical space. However, we lack interaction paradigms that support a coherent experience across these collocated technologies and enable them to work effectively as systems. This article presents a conceptual framework for building richly connected systems of collocated devices, and offers two implemented examples of interactive virtual worlds built on this framework. Aspects of this framework include multiple channels of real and apparent connectivity among devices: for example, multiple kinds of data networking, cross-device graphics and sound, and embodied mobile agents that inhabit the multi-device system. In addition, integration of the system with the physical world helps bridge the gap between devices. We evaluate the framework in terms of the types of user experiences afforded and enabled by the implemented systems. We also present a number of lessons learned from this evaluation regarding how to develop richly connected systems using heterogeneous devices, as well as the expectations that users bring to this kind of system. The core contribution of this paper is a novel framework for collocated multi-device systems; by presenting this framework, this paper lays the groundwork for a wide range of potential applications.

Due to the poor effect of traditional systems on constant temperature control, the paper proposes to design an embedded continuous temperature control system in a dynamic, intelligent building. In the smart building, the thesis takes the building as the research object and uses the embedded technology to design the overall structure diagram of the system. The thesis aims at the output control module of the thermostat. It uses the Peltier effect to develop the thermocouple closed-loop and drives the semiconductor refrigeration device select. In the software part, the paper establishes a cross-compilation environment, transplants embedded kernels, and sets fuzzy rules for constant temperature control. The validity of the system design is verified through experiments. It can be seen from the experimental results that the system has a better thermostat control effect.

In this paper, we propose a new versatile routing device that utilizes arrayed waveguide gratings (AWGs), optical switches, and optical circulators to implement reconfigurable optical add/drop multiplexers (ROADMs), optical interleavers, and optical cross-connect (OXC). With the development of dense wavelength division multiplexing (DWDM) technology, ROADM and OXC technologies have also been put into practical use. Thus, the optical signal can be routed directly in the optical network according to its wavelength without the need for optical-electrical-optical (OEO) conversion. Although different optical network units (ONUs) have different bandwidth requirements, the use of optical interleavers has successfully solved the connection problem between old and new systems. According to the numerical experiments of static characteristics, the proposed routing device can effectively implement three different functionalities, thereby providing greater flexibility for fiber optic network applications.

A robust three-perspective digital image correlation (DIC) system based on a cross dichroic prism and single three charge-coupled device (3CCD) color cameras is proposed in this study. Images from three different perspectives are captured by a 3CCD camera using the cross dichroic prism and two planar mirrors. These images are then separated by different CCD channels to perform correlation calculation with an existing multi-camera DIC algorithm. The proposed system is considerably more compact than the conventional multi-camera DIC system. In addition, the proposed system has no loss of spatial resolution compared with the traditional single-camera DIC system. The principle and experimental setup of the proposed system is described in detail, and a series of tests is performed to validate the system. Experimental results show that the proposed system performs well in displacement, morphology, and strain measurement.

AbstractFor the development of new stent designs, the compliance of the surrounding biological tissue has to be considered. We expect to obtain parameters for simulation, stent dimensioning, and the forces acting on the stent after implantation. Starting point of the investigations is the commercially available Metricath system allowing cross-sectional lumen area measurements of arteries. Its working principle is based on the pressure-volume relationship using a balloon catheter, which is inflated to a specific pressure of about 250 mmHg and conforms to the shape and size of the lumen. However, for compliance charts multiple pressure levels and a larger pressure range are needed. To overcome this technical limitation, the Metricath balloon catheter is combined with a new inflation device, called pV-Monitor. The presented cross-sectional lumen area measurements in rigid tubes and compliance investigations of elastic tubes demonstrate the feasibility of the pV-Monitor system.

AbstractInterest in wave energy converters to provide autonomous power to various ocean-bound systems, such as autonomous underwater vehicles, sensor systems, and even aquaculture farms, has grown in recent years. The Monterey Bay Aquarium Research Institute has developed and deployed a small two-body point absorber wave energy device suitable to such needs. This paper provides a description of the system to support future open-source access to the device and further the general development of similar wave energy systems. Additionally, to support future control design and system modification efforts, a set of hydrodynamic models are presented and cross-compared. To test the viability of using a linear frequency-domain admittance model for controller tuning, the linear model is compared against four WEC-Sim models of increasing complexity. The linear frequency-domain model is found to be generally adequate for capturing system dynamics, as the model agreement is good and the degree of nonlinearity introduced in the WEC-Sim models is generally less than 2.5%.

For high voltage SiC bipolar devices, carrier lifetime is an important parameter, and for optimization of device performance, we need to control distribution of the carrier lifetime in a wafer. So far, there have been limited systems for depth-resolved carrier lifetime measurements without cross sectional cut. In this study, we adopted a free carrier absorption technique and made local overlapping of the probe laser light with excitation laser light to develop depth-resolved carrier lifetime measurements. We named the developed system a microscopic FCA system and demonstrated measurement results for samples with and without intentional carrier lifetime distribution.

ABSTRACTThis study provides a solution for the bass extension of a microspeaker system in a mobile device that involves using a resonant combination of a front chamber and a rectangular, long, pipe-shaped port. The efficient resonant coupling of the microspeaker system to the acoustic load in this structure enables a microspeaker with modest cone displacement to achieve a high sound pressure level (SPL) and bass extension below the resonance of the microspeaker in free air, and the total dimensions of the structure are minimized. A combination of electro-mechanic-acoustic and finite element methods was applied to determine the SPL and bass extension levels for mobile devices. Simulation results show acceptable agreement with experimental results. A suitable extended-range microspeaker system was applied in a 10 inch tablet. The audio frequency response could be extended from 630 to 300 Hz with the greatest loudness. As much as possible add low bound frequency extension to make the article more clear. Finally, five cases of parameter settings for the front chamber volume, rear chamber volume, rectangular pipe-shaped port, cross-sectional area, and opening area were studied. The results can be applied for optimizing a suitable extended-range microspeaker system.

In this work, a ZnO-based resistive switching memory device is characterized by using simplified electrical conduction models. The conventional bipolar resistive switching and complementary resistive switching modes are accomplished by tuning the bias voltage condition. The material and chemical information of the device stack including the interfacial layer of TiON is well confirmed by transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) analysis. The device exhibits uniform gradual bipolar resistive switching (BRS) with good endurance and self-compliance characteristics. Moreover, complementary resistive switching (CRS) is achieved by applying the compliance current at negative bias and increasing the voltage at positive bias. The synaptic behaviors such as long-term potentiation and long-term depression are emulated by applying consecutive pulse input to the device. The CRS mode has a higher array size in the cross-point array structure than the BRS mode due to more nonlinear I–V characteristics in the CRS mode. However, we reveal that the BRS mode shows a better pattern recognition rate than the CRS mode due to more uniform conductance update.

Radiative neutron capture cross sections are very important in the field of basic physics research and nuclear device R&D. The Back-n white neutron beam line of China Spallation Neutron Source (CSNS) is the first spallation neutron beam line in China. On the purpose for radiative neutron capture cross section measurement, a C6D6 detector system was built in the Back-n experimental station. The pulse height weighting technique (PHWT) was used to make the system’s detective efficiency independent of the cascade path and the energy of cascade gamma rays. The neutron energy spectrum was measured for the energy between 1eV and 80keV with a 6Li loaded ZnS scintillation detector. Besides, a testing experiment with 197Au and 169Tm samples was carried out to examine this system. According to the preliminary results, this C6D6 detector system can be used to perform neutron capture cross section measurement.

At present, all railways tend to increase the speed of passenger trains and axle loads in transportation of goods. These processes contribute to the improvement of rolling stocks and railway infrastructures. At the same time, there is a need to maintain a high level of safety in transportation. Therefore, experimental research and feasibility studies of the existing monitoring solutions are of the highest priority. Being experimental in nature, this study is aimed at increasing the reliability of the strain-gauge method in measurement of dynamic forces transferred from the wheel to the rail in real operating conditions. Rail strains were experimentally studied under bidirectional loading using a special-purpose impact device. Results of this research are presented in the paper. An experimental measuring section was created for recording loads. Strain gauges were installed on rails in several cross-sections. Rails were loaded with a special-purpose device, which was designed to adjust a loading force and shift a contact point. The structure of the loading device and its basic features are described in the paper.

The purpose of this study was to assess the efficacy of standardized group achievement testing in screening and identifying mildly handicapped students for referral to special education programs. Stanford Achievement Test scores of students already placed in either regular or special education programs in four elementary schools were arranged according to four cutoff points: 20th, 15th, 10th, and 5th percentiles. At the 10th percentile cutoff, 71% of the special education and 97% of the regular education students were correctly identified. These results were cross-validated for students at two other elementary schools. The potential uses of this identification method as a preliminary screening device are discussed—particularly at a lower cutoff point of the 5th percentile.

The cross-correlation method allows phase-noise measurements of high-quality devices with very low noise levels, using reference sources with higher noise levels than the device under test. To implement this method, a phase-noise analyzer needs to compute the cross-spectral density, that is, the Fourier transform of the cross-correlation, of two time series over a wide frequency range, from fractions of Hz to tens of MHz. Furthermore, the analyzer requires a high dynamic range to accommodate the phase noise of high-quality oscillators that may fall off by more than 100 dB from close-in noise to the noise floor at large frequency offsets. This paper describes the efficient implementation of a cross-spectrum analyzer in a low-cost FPGA, as part of a modern phase-noise analyzer with very fast measurement time.

Compact cross-grating spectrometers are inspired by classical high-end Echelle spectrometers and allow to acquire a large spectrum with a high spectral resolution in a single shot. To decrease the size of an Echelle spectrometer substantially, a cross grating was employed combining both required dispersive functionalities. First, an Echelle grating diffracts light in several higher diffraction orders, while a superposed, perpendicularly oriented cross-disperser is used in first diffraction order. In this contribution, we report on the realization of a cross-grating spectrometer employing a folded reflective beam path. A toric-convex mirror was introduced allowing aberration compensation. We present the basic concept and optical design of the system and discuss the mechanical implementation and the adjustment process. Here, different laser sources and gas emission lamps are used to realize the system and derive the optical performance. In particular, the spectral resolution in the different diffraction orders is determined for the realized device.

Restoration of the rotary-drive device after a long non-use is an important strategic task, and the search for a way to restore it is an urgent task of the study. Previously it was found that the long-term non-use of the rotary-drive device led to a deterioration in the kinematic accuracy of its gearboxes. This article discusses possible options for restoring the kinematic accuracy of gearboxes of the rotary-drive device by increasing the metal or introducing into the control system an electromechanical device for selecting the backlash. It is shown that the restoration of the geometry of gears, as well as the bearing seats is possible, however, it requires the use of specialized equipment and significant costs. Ensuring the required kinematic accuracy due to the introduction of an electromechanical choice of backlash is achieved by considering the two schemes of the backlash-picker. The performed simulation of the operation of the drive system with an electromechanical choice of backlash in the Simulink system showed that the use of a scheme with cross-links allows for the required kinematic accuracy without significant costs. As a result, it can be argued that the introduction of an electromechanical backlash device can restore the kinematic accuracy of the rotary-drive device to acceptable values.

In this study, a laparoscopic imaging device and a light source able to select wavelengths by bandpass filters were developed to perform multispectral imaging (MSI) using over 1000 nm near-infrared (OTN-NIR) on regions under a laparoscope. Subsequently, MSI (wavelengths: 1000–1400 nm) was performed using the built device on nine live mice before and after tumor implantation. The normal and tumor pixels captured within the mice were used as teaching data sets, and the tumor-implanted mice data were classified using a neural network applied following a leave-one-out cross-validation procedure. The system provided a specificity of 89.5%, a sensitivity of 53.5%, and an accuracy of 87.8% for subcutaneous tumor discrimination. Aggregated true-positive (TP) pixels were confirmed in all tumor-implanted mice, which indicated that the laparoscopic OTN-NIR MSI could potentially be applied in vivo for classifying target lesions such as cancer in deep tissues.

Background and Aim: Given the conflicting and unreliable evidence for using cross-links in posterior spine surgery, this review was conducted to highlight the different features and usefulness of these augmentation devices in spine surgeries. Methods and Materials/Patients: After searching databases using specific keywords, the relevant articles were ultimately selected and evaluated. Results: Biomechanically investigating the use of cross-links has not resulted in unanimous explanations for their effect. The site and direction of cross-links have been rarely investigated in the literature. Some studies recommended eliminating their application from clinical practice; nevertheless, these studies do not necessarily yield clinical benefits. Posterior spinal fixation with pedicle screws and without cross-links offers stability in all the planes in most clinical conditions. Conclusion: Excluding the cross-links in posterior spine surgery may shorten the operation time and reduce hospital costs. Researchers have reported other problems for cross-links such as late pain, device failure, infections, device prominence, and pseudarthrosis which may be obliterated through the avoidance of their combination in a spinal construct; nevertheless, the results of animal models of the application of special cross-links in a degenerative disorder or deformity suggest that diagonal cross-links provide the highest stability of the construct if they are matched with a rodonly system or with transverse cross-link constructs resulting in a rectangular configuration.

The novel user interface design of 1090ES Mode embedded ground-based transceiver (GBT) system is introduced in this paper. 1090ES mode is applied to the GBT system to receive airborne Automatic Dependent Surveillance-Broadcast (ADS-B) data. The output data of the GBT system are obtained through system’s serial port by processing information of ADS-B segment in 1090ES information structure. The novel user interface is based on Linux operating system and cross-complied on ARM platform to realize flight display function. The 1090ES mode data sent from aircraft is accurately recognized by ADS-B system software based on Linux, and precisely located in graphical interface either. The improved ADS-B system software in this user interface design occupies less resource, and can be easily transplanted to other embedded platform through cross-complied embedded Quasar Technologies (Qt) software. The complicated receiving and display of GBT system can be transformed into small size and portable device (4.6 inches) through this user interface design.

Abstract Objectives: to identify the main indications and reasons for discontinuing the use of the Levonorgestrel-Releasing Intrauterine System (LNG-IUS). Methods: a cross-sectional study was carried out from medical records of 327 women who used the LNG-IUS 52mg between January 2011 and December 2016 at a public hospital in the Northeast of Brazil. Results: the main indications for the use of the LNG-IUS were: contraception (32.7%), myoma/metrorrhagia (28.7%) and endometriosis/pelvic pain (22.3%). Of the 327 women, 68 (20.8%) had discontinued using the device. The most frequent reasons for discontinuation were: expulsion (9.2%), LNG-IUS expiration (3.7%), bleeding (2.4%) and pain (1.5%). Most patients had no difficulty in the insertion and did not require anesthesia/sedation. Among the 30 women who expelled the device, 17 (56.7%) had used it for metrorrhagia and myoma, 8 (26.7%) for contraception, and 5 (16.6%) for endometriosis/pelvic pain. Conclusions: the LNG-IUS is a well-accepted contraceptive method, with therapeutic applications for some gynecological conditions and a low expulsion rate.

With ports having moved downriver, redevelopment of central city areas and waterfronts has transformed the urban centres and created new economic bases for once industrial cities. Water transit systems, such as New York’s East River and City-Wide Ferry services and Gothenburg’s harbor ferries, are being installed by economic development agencies as a device to stimulate further land development, provide tourism opportunities, and promote a new social engagement with the river. Guangzhou’s water transit system is the third largest in Asia by passenger volume, behind only Bangkok and Sydney. This paper describes the Guangzhou system in depth, comparing its operations favourably with the world’s leading water transit systems. Comparisons are made in vessel design, route design, terminals, operations, and fares. The Guangzhou case is distinctive, with a mixture of cross-river and parallel routes, and an especially unique approach to subsidy that may be an option for North American cities considering water transit. Opportunities to further improve the system in line with international trends are identified, as well as a research agenda to further the knowledge of water transit operations and regulation generally.

Background: No data exist on the cutting efficiency of monopolar versus bipolar radiofrequency energy application systems on human meniscal tissue. Purpose: To compare the effects of monopolar and bipolar thermal energy systems on human meniscal tissue. Study Design: Controlled laboratory study. Methods: Fresh-frozen menisci were cut in cross-section into 180 pie-shaped specimens. A specially designed jig was used to consistently apply radiofrequency energy to the tissue under a constant 30-g force. Three different systems were tested at the low, middle, and high ranges, with application times of 1 and 3 seconds. Thermal effects were measured by image analysis microscopy. Results: No significant differences in thermal effects were found with respect to energy output for each system. Both the individual system tested and the application time had statistically significant effects on thermal damage, with the individual system tested having a greater effect. The mean depths of thermal change produced by the Mitek (bipolar) device were 564 and 648 μm at 1 and 3 seconds applications, respectively. The Arthrocare device (bipolar) produced depths of 1444 and 1697 μm at 1 and 3 seconds. The Oratec device (monopolar) produced depths of 895 and 1057 μm, respectively. Conclusions: A differential thermal effect was created in the meniscal tissue by three commercially available radiofrequency systems. Within the parameters of the experiment, all three systems limited thermal damage to a depth of less than 2 mm. The results appeared to depend more on the particular system used, not whether it had monopolar or bipolar electrodes. Clinical Relevance: These data imply reasonably safe (less than 2 mm) thermal changes in the meniscus after radiofrequency energy application from these three systems.

AbstractThe ability to prepare multiple cross-section transmission electron microscope (XTEM) samples from one XTEM sample of specific sub-10 nm features was demonstrated. Sub-10 nm diameter Si nanowire (NW) devices were initially cross-sectioned using a dual-beam focused ion beam system in a direction running parallel to the device channel. From this XTEM sample, both low- and high-resolution transmission electron microscope (TEM) images were obtained from six separate, specific site Si NW devices. The XTEM sample was then re-sectioned in four separate locations in a direction perpendicular to the device channel: 90° from the original XTEM sample direction. Three of the four XTEM samples were successfully sectioned in the gate region of the device. From these three samples, low- and high-resolution TEM images of the Si NW were taken and measurements of the NW diameters were obtained. This technique demonstrated the ability to obtain high-resolution TEM images in directions 90° from one another of multiple, specific sub-10 nm features that were spaced 1.1 μm apart.

The plant, which is similar to a prototype of helicopter, is characterized by its highly nonlinear and cross-coupled dynamics. In the first phase, the system is modelled using the Lagrangian approach and combining theoretical and experimental results. Thereafter, a hierarchical control architecture which combines a baseline feedback controller with an Iterative Learning Control algorithm is developed. Finally, the responses of the real device and a complete analysis of the learning behaviour are exposed.

In recent years, the organization of cross-country and popular races where hundreds of people participate has become a significant trend. In these events, runners usually subject the body to extreme situations that can lead to various types of indisposition, and they can also suffer falls. Currently, the electronic systems used in this type of race only monitor when runners pass through checkpoints. However, it is necessary to implement systems that enable the control of the population of runners and the monitoring of their status all the times. For this reason, this paper proposes the design of a low-cost system for monitoring and controlling runners in this type of event. The system is formed by a network architecture in infrastructure mode based on low-power wide-area network (LPWAN) technology. Each runner will carry an electronic device that will allow their position and vital signs to be monitored. Likewise, it will incorporate an S.O.S. button that will allow runners to send a signal to the organization should they require help. All these data will be sent through the network to a database, which will allow the organization and bystanders of the race to check the location and history of vital signs of runners. This paper shows the proposal of a design of our system and the different practical experiments that have been carried out with the devices that have allowed for the proposition of this design.

One example of technological developments in signaling systems in Indonesia is the use of detection facilities on rail lines. A detector is a device that functions to detect the presence or absence of train facilities on the railroad track. Detection equipment is divided into two types, namely axle counter and track circuit. Track circuit detects the presence of trains on the rails, while the axle counter functions to count train axles. This study aims to find a detection system for facilities that is suitable and in accordance with the conditions of the Surabaya-Madiun cross and find out the characteristics for the installation of detection facilities in accordance with the pathway. To find out the appropriate facility system, the two tools are analyzed in terms of system reliability, environmental influences, advantages and disadvantages, disruptions, maintenance, and operations. The results showed that an effective and efficient way of detecting traffic in Surabaya - Madiun was the detection of a double head axle counter facility. This tool is very suitable to be installed in the emplacement.

One potential method to estimate noninvasive cuffless blood pressure (BP) is through measurement of pulse wave velocity (PWV), which can be characterized by measuring the distance and the transit time of the pulse between two arterial sites. To obtain the pulse waveform, bioimpedance (BI) measurement is a promising approach because it continuously reflects the change in BP through the change in the arterial cross-sectional area. Several studies have investigated BI channels in a vertical direction with electrodes located along the wrist and the finger to calculate PWV and convert to BP; however, the measurement systems were relatively large in size. In order to reduce the total device size for use in a PWV-based BP smartwatch, this study proposes and examines a horizontal BI structure. The BI device is also designed to apply in a very small body area. Our proposed structure is based on two sets of four-electrode BI interface attached around the wrist. The effectiveness of our system and approach is evaluated on 15 human subjects; the PWV values are obtained with various distances between two BI channels to assess the efficacy. The results show that our BI system can monitor pulse rate efficiently in only a 0.5 × 1.75 cm2 area of the body. The correlation of pulse rate from the proposed design against the reference is 0.98 ± 0.07 (p < 0.001). Our structure yields higher detection ratios for PWV measurements of 99.0 ± 2.2%, 99.0 ± 2.1%, and 94.8 ± 3.7% at 1, 2, and 3 cm between two BI channels, respectively. The measured PWVs correlate well with the BP standard device at 0.81 ± 0.08 and 0.84 ± 0.07 with low root-mean-squared-errors at 7.47 ± 2.15 mmHg and 5.17 ± 1.81 mmHg for SBP and DBP, respectively. Our results inform future designs of smart watches capable of measuring blood pressure.
