US Patent:

50763750, Dec 31, 1991

Filed:

May 14, 1990

Appl. No.:

7/523253

Inventors:

Benny N. Dillon - Worthington OH
Neil C. Griffen - Westerville OH
Mark E. Weihs - Toledo OH

Assignee:

Mettler-Toledo, Inc. - Worthington OH

International Classification:

G01G 2318
G01L 122

US Classification:

177 45

Abstract:

A digital load cell includes a rocker pin, guided beam torsion ring or other counterforce, a circuit board mounted on the counterforce and an enclosure sealing the circuit board and all but the load bearing surfaces of the counterforce. The circuit board includes an A/D converter and a micrcomputer. Digital communication is provided with the circuit board through a connector mounted on the enclosure. Weight data are corrected digitally. The load cell may be calibrated, characterized, controlled and monitored digitally through the connector from a remote location without physically penetrating the enclosure. One or a number of digital load cells may be connected to a computer or controller to form one or more weighing scales.

Appl. No.:

8/059023

Assignee:

ADB-Alnaco, Inc. - Columbus OH

International Classification:

B64F 118

US Classification:

340953

Abstract:

A microprocessor-controlled airfield lighting control and monitoring system having bi-directional communication between the controlling microprocessor and the airfield lights and/or sensors. The system also includes a metal container for the remote control microprocessor and an improved attachment arrangement for the power transistor associated therewith. A DC power supply is connected to the remote controller microprocessor and has an integrated circuit adapted to sense a threshold voltage, which causes the power transistor to short around the associated power source.
