Maintaining the health and well‐being of animals is critical to efficiency profitability livestock operations. However, it can be difficult monitor in large group‐housed settings without assistance technology. This study presents a system that uses depth images continuously track individual pigs environment. It an alternative traditional manual observation used by both researchers producers for analysis animal activities behaviours. The tracking method exploits consistent shape fixed number...
As a first step toward building smart home behavioral monitoring system capable of classifying wide variety human behavior, wireless sensor network (WSN) is presented for RSSI localization. The low-cost, non-intrusive uses watch worn by the user to broadcast data WSN, where strength radio signal evaluated at each WSN node localize user. A method that simultaneous localization and mapping (SLAM) calibration, providing automated fingerprinting associating patterns user's location within living...
Minimally-invasive laparoscopic procedures have proven efficacy for a wide range of surgical procedures, but notable shortcomings, including limited instrument motion and reduced dexterity. Endoscopic robots, like the intuitive da Vinci system, become an effective tool many types surgeries; however, these tools still fundamental limitations with manipulator access, which reduces their effectiveness colectomy, cholecystectomy, gynecologic oncology. Laparo-endoscopic single-site (LESS) robots...
Many wireless sensor network applications require a gateway device to interface with services running on the Internet. Because of software complexity involved in this device, it is often realized using real-time operating system an application processor. Most systems burden user developing protocol handling and configuration management inside application. In paper, we present Angelos Gateway - turnkey, low-cost, Linux-powered WSN that provides socket-based environment for rapid...
Most Wireless Sensor Network platforms - such as the Mica, Iris, and Telos B families of motes use low-power 8-bit microprocessors which have limited memory processing capabilities, thus requiring researchers to implement communication protocols data routines using low-level programming practices that are tedious cumbersome. Rich features available in modern desktop operating systems threads, management, exception-handling largely absent. The Microsoft .NET Micro Framework implements a...
Current techniques for diagnosing skin cancer lack specificity and sensitivity, resulting in unnecessary biopsies missed diagnoses. Automating tissue palpation morphology quantification will result a repeatable, objective process. LesionAir is low-cost diagnostic tool that measures the full-field compliance of by applying vacuum force measuring precise deflection using structured light three-dimensional (3D) reconstruction. The technology was tested benchtop setting on phantom small clinical...
Robotic surgical platforms require vision feedback systems, which often consist of low-resolution, expensive, single-imager analog cameras. These systems are retooled for 3D display by simply doubling the cameras and outboard control units. Here, a fully-integrated digital stereoscopic video camera employing high-definition sensors class-compliant USB interface is presented. This system can be used with low-cost PC hardware consumer-level displays tele-medical applications including military...
The Texas Instruments eZ430-Chronos development kit is a popular wireless platform for researchers, commercial developers, and hobbyists. Built into the form factor of standard wrist watch, Chronos ideal body area networks (WBANs), indoor localization, activity detection. Many these applications requires knowledge RF performance platform, which has never been characterized by nor any third parties. Here, we provide experimental data characterizing watch in various configurations, including...
Respiratory training is a critical component of many rehabilitation plans, including those stroke patients. Many current respiratory techniques lack efficient methods for quantifying progress and updating testing parameters. A previously-developed microcontroller-based device, designed in conjunction with clinicians at the Institute Rehabilitation Science Engineering Madonna Hospital, has demonstrated promising results. Here, prototype revised device that network connected remoatly sends...
ABSTRACT Introduction The U.S. Space Force was stood up on December 20, 2019 as an independent branch under the Air consisting of about 16,000 active duty and civilian personnel focused singularly space. In addition to Force, plans by NASA private industry for exploration-class long-duration missions moon, near-earth asteroids, Mars makes semi-independent medical capability in space a priority. Current practice space-based medicine is limited relies “life-raft” scenario emergencies....
