Walter Paul Sjursen - Washington Crossing PA
Gary John Hollingsworth - Rocky Hill NJ
Marvin Allan Leedom - Princeton NJ
Derek Dwayne Mahoney - Manalapan NJ

Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

H02J 700

US Classification:

307130, 307140, 307150

Abstract:

A metal-air cell for powering electronic components in a hearing aid device. The metal-air cell has a flex circuit inside containing an anode mixture. The flex circuit comprises a flexible substrate having a cathode electrode area at one end of the substrate, an anode electrode area at another end of the substrate and an electronic components area in between. The flexible substrate is disposed within the housing. The cathode electrode area is near a top surface of the housing, and the anode electrode area is near a bottom surface of the housing and in contact with the anode mixture. The cathode electrode area has air flow means for permitting air into the housing. An isolation means between the cathode electrode area and the anode mixture is provided for preventing contact between the cathode electrode area and the anode mixture.

International Classification:

H04R 2500

US Classification:

381322, 381323, 381328

Abstract:

A hearing aid includes a microphone, signal processing circuitry, receiver and integral battery all mounted in a casing. The battery may be a metal-air device. The battery may be activated by removing a tape which blocks air holes on the battery or, if the battery is sealed into the hearing aid, air-vent holes on the hearing aid. The hearing aid may also include an air-blocking mechanism which is activated when the hearing aid is inserted in the users ear and deactivated when the hearing aid is removed. The assembled hearing aid may also be packaged in non-permeable packaging material to extinguish battery activity. The hearing aid may also include an electronic switch which monitors the battery potential to disconnect the battery from the hearing aid electronics when the battery is deprived of oxygen and which connects the battery to the electronics when oxygen is provided to the battery. In one embodiment of the invention, the integral battery is a rechargeable battery which is recharged via external contacts. In another embodiment, the battery is recharged using an induced alternating current potential which is rectified before being applied to the battery.

International Classification:

A61M 3700

US Classification:

604131, 604151

Abstract:

A device for delivering fluid, such as insulin for example, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending towards an outlet connected to the exit port assembly. A threaded lead screw is received in the reservoir and a plunger has an outer periphery linearly slideable along the side wall of the reservoir and an inner periphery threadedly received on the lead screw. The plunger is non-rotatable with respect to the side wall such that rotating the lead screw causes the plunger to advance within the reservoir and force fluid through the outlet. The device also includes a dispenser having a return element for causes rotation of the lead screw, and a shape memory element. A changeable length of the shape memory element decreasing from an uncharged length to a charged length resets the return element.

International Classification:

A61M 3100

US Classification:

604131, 604 67

Abstract:

A device for delivering fluid, such as insulin, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending along a longitudinal axis towards an outlet connected to the exit port assembly, and a plunger assembly received in the reservoir. The plunger assembly includes a two-way shape memory element connecting first and second lateral segments, and having a changeable length decreasing from an uncharged length to a charged length when at least one charge is applied to the shape memory element. Successively applying a charge and removing the charge from the two-way shape memory element causes longitudinal movement of the plunger assembly towards the outlet of the reservoir in order to cause fluid to be dispensed from the reservoir to the exit port assembly.

International Classification:

H04R 25/00

US Classification:

381322, 381328, 381324

Abstract:

A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB.
