Patent number: 9736595Abstract: A two-port air pump speaker that includes at least two active, phase-modulated, bi-directional shutters and an ultrasonic pumping chamber having at least two ports; a first port facing towards the listener, the forward port, and a second port facing another direction, the backward port which may be behind an acoustic baffle or inside a speaker enclosure. A two-port speaker with two active steering shutters can create continuous bi-directional airflow which leads to low distortion reproduction of low audio frequencies. The same improved design can be used also for other applications where acoustic modulation is required, especially in ultrasonic frequencies.Type: GrantFiled: June 23, 2016Date of Patent: August 15, 2017Assignee: DSP Group Ltd.Inventor: Ori Elyada

Patent number: 9445747Abstract: An apnea detector is disclosed. A detector unit in communication with a capacitive type sensor is adapted to receive an electrical signal which is indicative of variable capacitance resulting from movement of a subject and to emit an alert signal when the received electrical signal is indicative of symptoms of apnea. In one embodiment, a detector unit is in communication with a curvature sensor adapted to detect a variable curvature of a subject body surface resulting from breathing patterns of a subject. The detector unit is attached to an article of clothing of the subject.Type: GrantFiled: September 10, 2012Date of Patent: September 20, 2016Assignee: DIAPERTECH LTDInventors: Shaked Rahamim, Ori Elyada

Publication number: 20100328075Abstract: An apnea detector is disclosed. In some embodiments, a detector unit in communication with a capacitive type sensor is adapted to receive an electrical signal which is indicative of variable capacitance resulting from movement of a subject and to emit an alert signal when the received electrical signal is indicative of symptoms of apnea. In one embodiment, a detector unit is in communication with a curvature sensor adapted to detect a variable curvature of a subject body surface resulting from breathing patterns of a subject. The detector unit is attached to an article of clothing of the subject. A monitoring system comprises a detector unit for detecting one or more subject related parameters of interest and for emitting acoustical information after determining that a subject related parameter of interest has a predetermined status, and a stationary unit disposed within an audible range of the detector unit for receiving the emitted acoustical information.Type: ApplicationFiled: April 19, 2010Publication date: December 30, 2010Inventors: Shaked Rahamim, Ori Elyada
