US Patent:

56279035, May 6, 1997

Filed:

Oct 6, 1993

Appl. No.:

8/132652

Inventors:

Edward M. Porrazzo - Citrus Heights CA

Assignee:

Chain Reactions, Inc. - Gold River CA

International Classification:

H04R 2500

US Classification:

381202

Abstract:

A variable geometry transducer diaphragm having an electrical conductor layer, with a conductor pattern, is positioned on an insulating layers. Magnets used to create an electromagnetic field around the conductors may be placed in the insulating layer or formed as part of the frame supporting the diaphragm. Alternatively, the frame may be constructed to function as plates of a capacitor creating an electrostatic field around the diaphragm.

Assignee:

Personal Fertility Technologies, Inc. - Gold River CA

International Classification:

G01N 2184

US Classification:

422 61

Abstract:

This Invention relates to a fertility analysis and reproductive health system that is applicable to both female and male mammals. In particular the Invention is a portable, handheld, integrated unit which can be manufactured out of plastic. The unit can be disposable for hygienic purposes, or cleaned or sterilized for repeated use as desired. The present Invention has numerous aspects. These aspects include: (1) A unique, immediate testing methodology employing any and all female fluids or secretions called Positive Fertility Testing, "PFT"; (2) The creation of a plastic, completely integrated, portable, self-contained and self-focusing Examination System which relies on a visual reference system making it language independent; (3) A Test Area Section with replaceable slides where different, specific wavelengths of light are employed; (4) The embodiment of compound test areas so that multiple Positive Fertility Tests may be conducted simultaneously; (5) Implementing the ability to immediately perform two or more Positive Fertility Tests simultaneously using different female fluids or secretions; (6) Providing a novel battery powered microprocessor system to automatically perform the Positive Fertility Testing; (7) The embodiment of the most accurate indicator of positive ovulation whereby the woman may pinpoint times of greatest fertility, thereby knowing the optimum time period for achieving pregnancy. Alternatively, the use of the Invention as a birth control device; or to identify hormonal imbalances, irregular cycles or infertility; introduce young women to their fertility cycle, sexuality and health; (8) The embodiment of a unique, immediate testing methodology employing male fluids and secretions, including saliva, semen and sperm for determining the reproductive health and fertility status of a male called Positive Male Fertility Testing, "PMFT".

Charles Stevenson - Auburn CA
Edward Porrazzo - Citrus Heights CA

Assignee:

Chain Reactions, Inc. - Citrus Heights CA

International Classification:

H04R 2500

US Classification:

381203

Abstract:

An electromagnetic transducer diaphragm having an electrical conductor layer, with a conductor pattern, positioned between two insulating layers of a flexible, electrically-insulating material bonded together to protect the diaphragm. An electrical current can flow through the conductors to produce magnetic and electrostatic fields around said conductors which interact with an electromagnetic field to produce mechanical displacement of the diaphragm which in turn produces an audio signal. Non-ferrous supports can be used to support the diaphragm. A magnet or magnets may be used to create the electromagnetic field. The magnets can be bonded to the cross arms of the non-ferrous support.

International Classification:

H04R 2500

US Classification:

381194

Abstract:

Loudspeaker improvements are disclosed to add versatility and economy, particularly for multimedia applications. These improvements include: (1) the printing of voice coil conductors, (2) adding conductive elements to the sound driver surface, (3) using multiple coil paths around a single voice coil former to drive the overall sound driver surface, (4) creating a simple digital loudspeaker with multiple coil paths, (5) implementing multiple functions in the multiple coil loudspeaker/transducer, (6) creating integrated systems with a series of multiple function, multiple coil loudspeakers/transducers and (7) providing a novel subwoofer loudspeaker housed in a cylinder.
