Abstract: A movement detection device includes a signal transmission device configured to transmit a radar signal transmission toward a target area and to receive reflected radar signals, and a signal analysis device configured to analyze the reflected radar signals to detect a movement in the target area that is indicative of micro-shivering. In response to detecting the micro-shivering, the movement detection device generates an alarm.

Abstract: A singles stick is provided for raising the top edge of a tennis net from its otherwise undisturbed position to convert a tennis net from doubles to regulation singles play. The singles stick comprise a base that abuts against the ground when the singles stick is installed and an upper staff that engages against the top edge of the net when the singles stick is installed. The base and the upper staff are telescopically connected to one another to allow their combined length to be varied between an extended position and a collapsed position. In the extended position, their combined length is sufficient to raise the top edge of the net from the position that edge has during doubles play. In the collapsed position, their combined length is sufficient to allow the singles stick to be stored in an equipment bag of the type used to carry tennis rackets and the like.

Abstract: A system for the treatment of obstructive sleep apnea packaged in a collar which can be worn by a patient without any special preparation. The collar is adjustable using a fastener such as hook and latch, to accommodate variations in neck size. The collar is properly oriented using variations in physical shape and/or color. An optional feedback system permits the patient to readily verify proper orientation.The collar contains at least one sensor to monitor functioning of the respiratory system of the patient.The output of the sensor(s) is processed by battery powered electronics located within or in proximity to the collar. When an apnea episode is detected, the electronics module generates bursts of pulsatile current which are conducted to electrodes located on and positioned by the collar or in proximity to the collar.

Abstract: An improved net height adjustment device (20) or (70) includes an elongated stick member (22) for raising the top edge of an athletic net (10) from its otherwise undisturbed orientation to convert a tennis net from doubles to regulation singles play. The device (20) or (70) includes a support member (42) for pivotally connecting the stick member (22) to one of the end posts (14) that support the net (10). Support member (42) also includes an extensible connection that allows stick member (22) to be pulled out away from a storage position adjacent post (14) to a use position spaced from the post.
