Development of new and innovative applications for high precision differential global positioning systems (DGPS) has exploded in the last two years. Real-time three-dimensional accuracy’s of under three centimeters and processed position update rates in excess of four hertz, along with position update latencies of under eighty milliseconds are now commercially available. Immediate position info...

The work presents advances in the implementation of an ultrasound based silent speech interface system. Use of a portable acquisition device, a visual speech recognizer system with a language model, and real time tests with the Julius system are described. Experiments with two types of visual feature extraction are also presented. Results show that good recognition and real time performance can...

Traditional forensic analysis of hard disks and external media typically involves a “dead analysis” of a powered down machine. Forensic acquisition of hard drives and external media has traditionally been accomplished by one of several means: standalone forensic duplicator; using a hardware write-blocker or dock attached to a laptop, computer, workstation, etc.; forensic operating systems that ...

Electromyography signals is one of the most important studies of muscle function used in wide area including kinesiology, rehabilitation, and occupational and sports medicine. The measurement of electromyogram always requires multichannel as every movement will involve a group of muscles. Commercial single or multichannel surface electromyogram data acquisition system is very expensive for begi...

Abstract— In this paper a novel portable posture monitoring and feedback system is proposed. System is designed to be unobtrusively used during daily activities and provide alternative solution to traditional bracing used in treatment of scoliosis. System consists of wearable sensor network for posture data acquisition, wireless data transmission and conventional smartphone for data processing...

This article addresses synchronous acquisition of high-speed multimodal speech data, composed of ultrasound and optical images of the vocal tract together with the acoustic speech signal, for a silent speech interface. Built around a laptop-based portable ultrasound machine (Terason T3000) and an industrial camera, an acquisition setup is described together with its acquisition software called ...

Rapid, on-the-spot diagnostic and monitoring systems are vital for the survival of patients with intracranial hematoma, as their conditions drastically deteriorate with time. To address the limited accessibility, high costs and static structure of currently used MRI and CT scanners, a portable non-invasive multi-slice microwave imaging system is presented for accurate 3D localization of hematom...
