Filed:

Apr 5, 2004

Appl. No.:

10/818182

Inventors:

Dale H. Mugler - Hudson OH, US
Yan Wu - Statesboro GA, US

Assignee:

The University of Akron - Akron OH

International Classification:

G06F 11/30
G06F 15/00
G21C 17/00

US Classification:

702182

Abstract:

A system and method for determining a predicted value of a function from at least one previous value of said function and at least one second-derivative value of the function. The system includes a sensor provided to sense a second-derivative value of the function and transmit an oscillatory signal representing the sensed second-derivative value, a computer-readable memory in communication with the sensor to store the previous value of the function and the second-derivative value, and a feature for computing the predicted value of the function using an integration algorithm including a coefficient of integration that is dependant upon at least a frequency of the signal.

International Classification:

H02J 7/00

US Classification:

320135

Abstract:

Methods and systems for depowering an automotive battery in a controlled manner. The methods comprise (i) providing a depowering medium comprising one or more non-ionic electric conductors (for example, a carbon conductor) dispersed in a substantially non-ionic aqueous medium; (ii) contacting terminals of the battery with the depowering medium; and (iii) maintaining contact between the depowering medium and terminals for a period of time sufficient to depower the battery. The systems comprise (i) the depowering medium; and (ii) a container configured to receive a battery and the depowering medium such that the battery body is contacted with the depowering medium prior to the terminals.

Assignee:

The University of Akron - Akron OH

International Classification:

G05B 1302

US Classification:

700 44

Abstract:

A system and method for calculating a future function value, such as velocity, for an object, from derivative values, such as acceleration, includes a sensor, such as an accelerometer, coupled to an object, such as a car. By predetermining a sampling rate of the derivative values and determining the highest frequency in the sampled signal, a set of prediction coefficients can be derived for use in a prediction formula which generates the future function value. A processor, which derives the prediction coefficients and implements the prediction formula may use the future function value to control operation of the object or a related object. By including a past function value in the prediction formula, a highly accurate future function value can be determined.

Appl. No.:

14/722893

Inventors:

- Detroit MI, US
Qian Lin - Troy MI, US
Yan Wu - Troy MI, US

International Classification:

H01M 2/06
H01M 2/02

Abstract:

Methods and battery cells formed thereby are provided that minimize issues with an exposed metallic layer at the peripheral edge of a flexible laminate forming a battery cell pouch. Sealing the periphery of the pouch is optimized projecting terminals of the electrochemical cell through perforations in the flexible laminate at a folded edge thereof. The folded edge does not present an exposed metallic layer and does not require a sealing material or use of sealing operation complicated by the terminals.
