Filed:

Nov 13, 2007

Appl. No.:

11/983972

Inventors:

John Arthur Fee - Garland TX, US
Brian L. Graham - Carrollton TX, US

Assignee:

Advanced Battery Management, LLC - Irving TX

International Classification:

H02J 7/00
H02J 7/04
G01N 27/416
G08B 21/00

US Classification:

320131, 320132, 320149, 324426, 3406361, 34063621

Abstract:

A system and method adapted to rejuvenate batteries at or near the resonant frequency of the battery. The present invention takes a battery and applies a modulated current charging signal to increase battery performance. A resonant signal is adapted to re-train and adjust battery materials for proper operation. By repeated charge/discharge cycling, battery memory decreases and/or battery capacity increases, thereby improving the battery capacity.

International Classification:

H02J 7/00

US Classification:

320137

Abstract:

A battery charger with a fixed frequency charging signal at or near the resonant frequency of the battery to be charged is presented. The present invention utilizes a microprocessor to modulate a current source at or near the resonant frequency of the battery to be charged without the use of a PLL. To simplify conventional modulated battery chargers, the PLL or other methods of phase correction are removed, reducing most of the calculation requirements for adjusting the phase angle, thereby reducing the piece count and ultimately cost and complexity. The result is a solution wherein charging occurs at or near the resonant frequency of the battery, and although suboptimal, the results are superior to traditional charging methods.

Appl. No.:

12/150804

Inventors:

William Stephen Hart - Plano TX, US
Brian L. Graham - Carrollton TX, US
John Arthur Fee - Garland TX, US

International Classification:

H02J 7/00

US Classification:

320150

Abstract:

A method and apparatus for acquiring battery temperature measurements using stereographic thermal imaging sensors or a simple single thermal imaging sensor which can detect increases in battery heat within the field of view of any single thermal sensor, or any combination of a plurality of thermal imaging sensors is presented. Infrared Detection (ID) using the thermal imaging sensor (pyrometer) is used to focus on certain parts of a housing thereby providing an ability to “see through” or “partially see through” the battery housing to battery cells enclosed by the battery housing. Advantageously, this affords the unique capability of measuring the battery temperature before heat propagates from an individual battery cell or a plurality of battery cells to the battery housing, allowing faster heat gradient detection. Moreover, universality of battery temperature monitoring is achieved by elimination of proprietary communication between the manufacturer of the battery and the charger.

Appl. No.:

17/892936

Inventors:

- Milwaukee WI, US
Kazim C. Demirhan - Garland TX, US
Brian J. Graham - Grand Prairie TX, US
Gary A. Minor - Flower Mound TX, US

International Classification:

F24F 1/01
F24F 13/26

Abstract:

An air diffuser of a heating, ventilation, and/or air conditioning (HVAC) system includes a mixing chamber having a circulation inlet and a mixing region, a room air intake fluidly coupled with the circulation inlet and separated from the mixing region by a blank-off plate, and a nozzle. The nozzle is disposed adjacent to the circulation inlet and configured to accelerate a conditioned air flow into the mixing region such that unconditioned room air is induced by the conditioned air flow to enter the mixing region through the circulation inlet and from the room air intake.
