The human tongue is involved in many essential daily activities and is comprised of eight muscles. To date tools for quantifications of the tongue's intrinsic motions are limited. In this study we explored the tongue's motion during a free-exploration paradigm, using a discreet wireless intra-oral wearable device. Six healthy subjects were instructed to freely move the tip of their tongue on the wearable device while attempting to cover the entire surface of the hard palate. The goal of this study is to compose a two-dimensional probability distribution model of the tongue's motion. We conclude that 90-seconds of non-continuous data collection was sufficient for visualizing the two-dimensional probability distribution of the free-exploration paradigm. The results suggest that the subjects concentrate the majority of the motion in the central portion of the palate.This paper describes a research collaboration with Studio 1 Labs to provide the characterization for a novel smart baby monitoring device which includes conductive fabrics. The electrical characterization of the conductive fabrics is important for designing a bedsheet that can adequately be sensitive to physiological movement. Electrical impedance spectroscopy (EIS) has been performed using the Metrohm Autolab potentiostat on a two-fabric interface. For an increase in applied weight, there was an overall decrease in impedance shown both in its real and imaginary components. A simple RC circuit model could be used to describe the system. A test bedsheet was made from a 3x3 conductive fabric matrix stitched into a cotton sheet. Conversely, an increase in resistance was observed from an increase in applied weights at the intersection points of the bedsheet. The following characterization provided useful insight into the future design of the smart bedsheet.Pulse wave and respiration are two important vital signals in diagnosing and treating diseases. In this paper, we investigated a Bio-impedance (BImp) based respiration and pulse wave monitoring system. The BImp signal is successfully extracted from a wearable device placed on the shoulder. Using the rate calculation algorithm, heart rate (HR), and respiration rate (RR) values are extracted accurately. The data is collected during different steps of breathing including slow, fast, deep, hold, and normal from 10 volunteers. The accuracy of HR results is compared to that of extracted from PPG with considering ECG based HR as reference. C646 nmr The extracted RR values are investigated against TCo2 sensor's output. The estimation of both RR and HR extracted from the BImp signal has higher accuracy compared to the other methods.With the growing trend towards personalized health, wearable fitness trackers have become a staple of the consumer electronics industry. As the prevalence of such devices booms, the medical community has been compelled to investigate the potential of such devices and explore how they can be used to create positive clinical outcomes. In this report we detail a smart-ring capable of determining heart rate (HR), respiratory rate (RR), blood oxygen saturation (SpO2), and temperature. The ring implements a photoplethysmogram (PPG), electrocardiogram (ECG), and thermistor to attain these metrics. After evaluation, significant correlation was found between the experimentally reported HR and RR recordings with their respective standards (p less then 0.05). Experimentally derived SpO2 had trial-dependent similarities with its reference standards, and temperature measurements were within expected values of normal skin temperature.It has been known that the fall of a patient in a hospital is a serious accident. In order to prevent such accidents, we have been studying the fall prevention using image processing technology. Our previous studies have detected the patient's end sitting position with high accuracy, but have problems responding to the sitting position of patients who are eating or responding to visitors. In order to solve these problems, this paper proposes a method to detect the patient's bed exit action by analyzing the posture of the patient extracted from the image of the monocular camera by long short-term memory (LSTM). Our proposed method introduces two strategies - abstraction of input information and use of relative position information for the input time-series human images, achieving a 99.2[%] detection rate of bed exit action with a 5.7[%] false detection rate. Detecting the bed exit action with high accuracy contributes to preventing the patient from falling down. The proposed solution handles only posture information that abstracts camera images for patient privacy purposes.In vivo fluorescence miniature microscopy has recently proven a major advance, enabling cellular imaging in freely behaving animals. However, fluorescence imaging suffers from autofluorescence, phototoxicity, photobleaching and non- homogeneous illumination artifacts. These factors limit the quality and time course of data collection. Bioluminescence provides an alternative kind of activity-dependent light indicator. Bioluminescent calcium indicators do not require light input, instead generating photons through chemiluminescence. As such, limitations inherent to the requirement for light presentation are eliminated. Further, bioluminescent indicators also do not require excitation light optics the removal of these components should make a lighter and lower cost microscope with fewer assembly parts. While there has been significant recent progress in making brighter and faster bioluminescence indicators, the advances in imaging hardware have not yet been realized. A hardware challenge is that despite potentially higher signal-to-noise of bioluminescence, the signal strength is lower than that of fluorescence. An open question we address in this report is whether fluorescent miniature microscopes can be rendered sensitive enough to detect bioluminescence. We demonstrate this possibility in vitro and in vivo by implementing optimizations of the UCLA fluorescent miniscope v3.2. These optimizations yielded a miniscope (BLmini) which is 22% lighter in weight, has 45% fewer components, is up to 58% less expensive, offers up to 15 times stronger signal and is sensitive enough to capture spatiotemporal dynamics of bioluminescence in the brain with a signal-to-noise ratio of 34 dB.
