Vertical Hand Position Estimation with Differential Barometery Supported by RFID Synchronization

We demonstrate how a combination of a wristworn and stationary barometer can be used to track the vertical position of the users Hand with an accuracy in the range of 30 cm To this end the two barometers synchronized each time an RFID reader detects them being in proximity of each other The accuracy is sufficient to detect a specific shelve of a cupboard on which something has been placed or determine if the users hand is touching hisher head or the torso The advantage of the method over IMU based approaches is that it requires only a wristworn sensor as could be implemented in a smartwatch and a reference either in an often access location in the environment or a pocket egin the smartphone and it does not depend on a stable magnetic environment The proposed system was tested in two different activities Shelve recognition in a warehouse picking scenario and movement of the arm to specific body locations Despite the simplicity of our method it shows initial results between 5562 and 7391 accuracy respectively

Characterisation of breathing and physical activity patterns in the general population using the wearable Respeck monitor

Clinical trials employing manual processes for data collection and administering of questionnaires are both timeconsuming and expensive to run Wireless bodyworn sensors coupled with mobile applications can be harnessed to automate the data collection process during clinical trials This paper describes the use of the Respeck monitor worn as a plaster on the chest for characterising breathing and physical activity patterns in the general population during their normal everyday lives The Respeck was worn by 93 subjects for periods ranging between 24 48 hours each amounting to a total of 106 days of continuous data Analysis of the results showed new insights such as the respiratory rate levels dropped by 439 breaths per minute on average during sleeping periods compared to the preceding daytime periods This change is higher than typically reported levels when normally measured directly before the subjects fall asleep which suggests that the Respeck can be used to detect sleep onset Previous research in activity patterns in the general population were based on highlevel activities logged using questionnaires A method is presented for clustering simple yet highdimensional activity patterns based on the Respeck data by first extracting meaningful features for each day The results reveal four distinct groups in the cohort corresponding to different identifiable lifestyles

Group Walking Recognition based on Smartphone Sensors

Human group activity represents a potentially valuable contextually relevant source of information which can be analyzed to support diverse humancentric applications In recent year more and more sensors are being pervasively spread in daily living environments so giving excellent opportunities for using ubiquitous sensing to recognize group activities In this paper we used smartphonebased data and edge computing technologies to address group activity recognition with particular focus on group walking The data are provided by two groups of participants using a smartphone with embedded 9DoF inertial sensors several features are generated to identify group membership of each subject Our results showed that the accelerometer rarely can be used alone to identify the group motion in most situations multiple sensor sources are required to determine group membership Moreover the use of 9DoF sensors to identify group affiliation is still challenging because in a multiuser scenario individual behaviors often have mutual contingency therefore the concept of proximity is also introduced to improve the classification algorithm

Estimation of Skin Conductance Response through Adaptive filtering

The importance of medical wearable sensors is increasing in aiding both diagnostic and therapeutic protocols in a wide area of health applications Among them the acquisition and analysis of electrodermal activity EDA may help in detecting seizures and different human emotional states Nonnegative deconvolution represents an important step needed for decomposing the measured galvanic skin response GSR in its tonic and phasic components In particular the phasic component also known as skin conductance response SCR is related to the sympathetic nervous system SNS activity since it can be modeled as the linear convolution between the SCR driver events modeled by sparse impulse signals with an impulse response representing the sudomotor SNS innervation In this paper we propose a novel method for implementing this deconvolution by an adaptive filter determined by solving a linear prediction problem which results independent on the impulse response parameters usually represented by sampling the biexponential Bateman function The performance of the proposed approach is evaluated by using both synthetic and experimental data

This paper presents a study on the radio channel characteristics between an endoscope capsule and an onbody antenna in different parts of the small intestine with different onbody antenna location options The study is conducted using finite integration technique based electromagnetic simulation software CST and one of its anatomical voxels An endoscope capsule with a dipole antenna is set inside different areas of the small intestine of the voxel model A recently published highlydirective onbody antenna designed for oninbody communications is used in the evaluations Different rotation angles of the capsule are also considered both with a layer model and a voxel model It is found that radio channel characteristics vary remarkably depending on the antenna location in the small intestine and location of the onbody antenna Thus the onbody antennas should be located carefully to ensure coverage over the whole intestine area However the path loss does not only depend on the distance between a capsule and the onbody antenna but also on the tissues between the capsule and onbody antennas Furthermore orientation of the capsule has also strong impact when linearly polarized antennas are used

Analysis of Channel Characteristic for Body Channel Communication Transceiver Design

In this paper body channel communication and its channel characteristic are investigated through measurement Previously the body channel communication has limitation in channel bandwidth due to its fluctuation To verify orientation 4 independent systemic factors are under test 1 the size of the signal electrode attaching on the skin 2 the size of the ground plane GND electrode that is not attaching on the skin 3 the channel distance between TX and RX through human body and 4 the length of cable connecting between the transceiver hardware and signal electrode The size of the electrode and channel communication does not have a high correlation However the cable length between electrode and device shows a large variation The newly proposed results are useful for hardware design and allow larger utilizable channel bandwidth that is promising for future BCC hardware design

MAC protocol with interference mitigation using negotiation among coordinators in multiple wireless body area networks

In this paperwe propose a new MAC protocol in presence of multiple wireless Body Area NetworkBANs which can for reduceinterWBAN interference and improve overall performance of all BANsA BAN system consists of a coordinator and some sensor nodes When coverages of multiple BANs are overlapped some packets transmitted form sensor nodes of different BANs cause interference Although an international standard for wireless medical BAN ie IEEE802156 can reduce intraWBAN interference within a single BAN interWBAN interference caused by coexistence of multiple BANs can not reduce effectively Therefore this paper proposes such a new MAC protocols method that coordinators of overlapped BANs can negotiate among coordinatorsof BANs In addition to enable priority control which is a feature of thestandard we propose a method that changes parameters of the proposedmethod according to priority of packets Throughput and delay time of the proposed scheme are illustrated by simulation in which it is convinced that the proposed scheme can improve overall performance suchas throughput and delay considering efficiency of priority control

PseudoDynamic UWB WBAN OffBody Radio Channel Measurements Preliminary Results

This paper presents measurement results on pseudodynamic ultra wideband offbody wireless body area network radio channels The measurements are performed in an anechoic chamber in a 28 GHz frequency band by utilizing a vector network analyzer A dynamic walking sequence was modeled by a test person who took five different body postures which were each measured statically As a result when observed together the five postures can be used to model a dynamic walking sequence as in a cinema film The focus is to observe the human body shadowing effect The antennas were attached on left and right wrist and left ankle The offbody antenna node was set on a pole The work was repeated for two prototype antenna types dipole and double loop The mean attenuations of the first arriving paths were noted to lie between 5268 dB No large differences were noted between the body postures The link between left ankle and the pole had the largest attenuation The averaged channel impulse response durations were noted to lie between eight to nine taps with a tap separation of 0167 ns in time The dynamic range on the averaged link types shows values between 1728 dB No clear difference was noted in the performance between the antenna types
