US Patent:

6898185, May 24, 2005

Filed:

Oct 19, 2000

Appl. No.:

09/693232

Inventors:

Oscar E. Agazzi - Irvine CA, US
Kenneth Phan Hung - Brea CA, US
David I. Sorensen - Scotts Valley CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F011/14

US Classification:

370241, 370242, 370248

Abstract:

A method and system for performing diagnostic tests on a real-time system controlled by a state machine. A sequence of states recorded as the state machine operates is used to determine error conditions. The sequence of states is compared to expected sequences of states to determine what, if any, errors have occurred. If the real-time system, such as a transceiver in a communication system, has adaptive components, the status of the adaptive components is used to estimate the condition of any external systems coupled to the real-time system.

Appl. No.:

11/060052

Lawrence Burns - Los Altos CA, US
Chong Woo - Fremont CA, US
David Sorensen - Scotts Valley CA, US

Assignee:

Pelikan Technologies, Inc. - Palo Alto CA

International Classification:

H03F 3/68

US Classification:

330124R, 330295

Abstract:

A power amplifier has an input conditioning circuit. At least first and second amplifiers are in parallel with each other and have inputs and outputs. An input signal is coupled to the inputs of the first and second amplifiers. A multi-input power combiner is provided. The outputs of the first and second parallel amplifiers are combined by the multi-input power combiner to add signals of the outputs constructively.

Appl. No.:

11/100978

Inventors:

David I. Sorensen - Glendale AZ, US

International Classification:

G08B 9/04

US Classification:

701 35, 340439

Abstract:

A vehicle has a safe and a utility device operable for performing a task having a result capable of being measured. A local processor is associated with local storage, each of which is housed in a safe preventing access thereto. An operator input console associated with the local storage is carried by the vehicle and is disposed outside the safe. A positioning system associated with the local processor generates position information of the vehicle during operation of the utility device. A sensor associated with the utility device and the local processor generates result information of the result of the operation of the utility device. The local processor stores in the local storage the position information, the result information, and the operator input information. The operator input console and the local processor are adapted and arranged preventing access to the local storage in response to operation of the operator input console.
