US Patent:

61429473, Nov 7, 2000

Filed:

Dec 4, 1998

Appl. No.:

9/205822

Inventors:

Howard Tran - Santa Clara CA
Roland Jeffrey Wyatt - San Jose CA
Gilbert Lima - Fremont CA

Assignee:

General Electric Company - Milwaukee WI

International Classification:

A61B 814

US Classification:

600459

Abstract:

A repairable compact ultrasound probe which is easy to assemble and disassemble, and which has cable load transfer and heat dissipation capabilities. The transducer assembly of the probe has a heat-conductive backing board which is fastened to a yoke incorporated in the cable assembly. The cable assembly further has a strain relief element which is secured in a separate operation following attachment of the yoke to the backing board. When the strain relief element is secured, the probe handle is compressed between the strain relief and a headshell of the transducer assembly, thereby forming a housing. To disassemble the probe, the strain relief is turned counterclockwise with respect to the transducer, thereby releasing the handle and allowing access to the probe interior.

International Classification:

Abstract:

Aspects of the disclosure provide for a method of transmitting state information using free-space optical communication. The method includes using one or more processors of a first communication device to collect state information of the first communication device. A supervisor signal that carries the state information is transmitted from the first communication device along with a beacon beam in a first solid angle. The supervisor signal is a frequency different from the one or more frequencies of the beacon beam. When a communication link is established between the first communication device and a second communication device, a plurality of data packets is transmitted from the first communication device to the second communication device in a second solid angle smaller than the first solid angle. A subset of the plurality of data packets that do not carry client data carries the state information of the first communication device.

International Classification:

G01B 11/27
H04B 10/112
H04B 10/25

Abstract:

Aspects of the disclosure provide for a method of aligning a tracking system of a communication device. The method includes receiving an optical beam at the communication device. A first beam portion is received at the tracking system, and a second beam portion is received at an optical fiber of the communication device. Using one or more processors, an first signal and an second signal is received from the tracking system. The one or more processors are also used to determine a phase difference related to the first signal and a second phase difference related to the second signal. An offset for the first signal and an offset for the second signal are determined based on the respective phase difference. The one or more processors then track the optical beam using the tracking system and the determined offsets.
