Appl. No.:

8/961480

Inventors:

Anthony Schooler - Bartlett IL
David Kang - Schaumburg IL
W. John Rinderknecht - Streamwood IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06F 700
G06F 1710

US Classification:

708304

Abstract:

An apparatus and method of filtering at least one set of data comprises determining a subset of Q data elements of a set of L data elements (12), and determining a filtered value based upon the subset of Q data elements (14). Each of the subset of Q data elements is greater than at most a first predetermined number of the L data elements and greater than or equal to at least a second predetermined number of the L data elements other than itself.

Appl. No.:

8/351854

Inventors:

Lawrence E. Connell - Naperville IL
David D. Kang - Schaumburg IL
Neal W. Hollenbeck - Schaumburg IL
William J. Roeckner - Algonquin IL

Assignee:

Motorola Inc. - Schaumburg IL

International Classification:

H04B 110
H04L 2508

US Classification:

375346

Abstract:

An interference dependent adaptive phase clock controller method and system includes synthesis of a signal processing clock signal (307). An interference signal (311 ) dependent on a phase of the signal processing clock signal is measured, and a phase correction signal (317) is provided dependent thereon. A magnitude of the interference signal is reduced by adjusting the phase of the signal processing clock signal (307) dependent on the phase correction signal (317).

International Classification:

H03K 2140

US Classification:

377 28

Abstract:

An apparatus and method for determining a time that a system's main power was inactive includes a counter circuit (171) for accumulating transitions of a clock signal (149) while the system's main power (117) is inactive. Preferably, another circuit (159, 125) determines a periodicity of the clock signal (149) after the system's main power (117) transitions active. Then a computational circuit, preferably a microcontroller (129), determines the time (183) that the system's main power (117) was inactive dependent on a number of transitions of the clock signal (149) accumulated by the counter circuit (171) when the system's main power (119) was inactive and the determined periodicity of the clock signal (149) after the system's main power (117) transitions active. Preferably, this apparatus and method are used in a vehicle to determine how long a time that an engine is turned off and to modify an engine control strategy dependent on that determined time.
