US Patent:

51390132, Aug 18, 1992

Filed:

Sep 30, 1988

Appl. No.:

7/251319

Inventors:

George L. Bell - Long Beach CA

International Classification:

G01N 2900

US Classification:

128 24AA

Abstract:

A direct indicator which serves to verify before each use that the transducer used in ultrasound therapy is actually operational and is transmitting ultrasound radiation to the patient. The indicator includes a liquid crystal layer which changes color in the presence of ultrasound radiation when an active ultrasound transducer is held against the surface of the indicator. A transparent vinyl layer is positioned on top of the liquid crystal layer, the vinyl layer not only serving to protect the liquid crystal layer from surface heat, but also enabling the liquid crystal to store the color pattern produced by the transducer for a predetermined time duration, for example, while the transducer is in use, to remind the operator that the transducer has been verified.

Abstract:

Methods and devices for demand bidding operation are described herein. One method of demand bidding operation includes determining a potential electric demand reduction for a particular facility, determining a bid for demand reduction based upon the determined potential electric demand reduction, submitting, via a computing device, the bid for demand reduction to a computing device of an electrical demand coordinating entity, receiving, via a computing device, notification of a triggering event that will trigger the demand reduction based upon the bid, and adjusting, via a computing device, demand at the particular facility based upon the demand reduction of the bid.
