Accelerometers have been widely used in wearable systems for gait analysis. Several gait cycle parameters are provided to quantify the level of gait regularity and symmetry. This study attempts to assess abnormal gaits of Parkinson disease (PD) patients based on the gait cycle parameters derived in real-time from an accelerometry-based wearable motion detector (WMD). The results of an experiment with 25 healthy young adults showed that there were significant differences between gait cycle parameters of normal gaits and abnormal gaits derived from the WMD. Five PD patients diagnosed as Hoehn and Yahr stage I to II were recruited. It is difficult to collect data of abnormal gaits of the PD patients; therefore, ranges of the gait cycle parameters of abnormal gaits of PD patients were estimated statistically based on the lower confidence limit of the gait cycle parameters of their normal gaits. These results may lead to the future development of wearable sensors enabling real-time recognition of abnormal gaits of PD patients. Ambulatory rehabilitation, gait assessment and personal telecare for people with gait disorders are also possible applications. © 2014 National Taiwan University. Source

The present invention is to provide an automated anti-snoring bed system, which includes a bed designed to support a user lying thereon and internally provided with a driving device, a sensing device able to send out a detection signal toward the users chest at regular intervals of time and receive a reflected signal returning from the user in response to the detection signal, and a control device. When the sensing device determines that the user is snoring according to the reflected signal, the sensing device sends out a control command to the control device and the control device then drives the driving device to change the configuration of the bed to a mode for stopping the user from snoring. Thus, the user is prevented not only from sleep disorders, but also from sleep apnea which may otherwise jeopardize the users sleeping quality and health.

The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.

The present invention provides an activity-sensing ground pad for integrating with a monitoring apparatus to continuously monitor human activity in the home environment. The activity-sensing ground pad includes a modular base, a sensing layer arranged on the modular base, an insulating layer arranged on the sensing layer, and a conductive elastic layer formed to cover the insulating layer. Specifically, the modular base has a first assembling side with a plurality of first engagement portions thereon and a second assembling side opposite to the first assembling side with a plurality of second engagement portions thereon, wherein a first electrical connector is arranged on one of the engaging portions, and a second electrical connector is arranged on one of the engaging portions in correspondence with the first electrical connector.
