US Patent:

41874218, Feb 5, 1980

Filed:

Mar 18, 1977

Appl. No.:

5/778883

Inventors:

Paul F. Key - Portola Valley CA
Anthony R. Lazzara - Portola Valley CA

Assignee:

Scientific Technology Inc. - Mountain View CA

International Classification:

H04B 900

US Classification:

250199

Abstract:

A relay for electromagnetic radiation occurring in the optical portion of the electromagnetic spectrum has a receiver and a transmitter. The receiver senses a propagated beam of electromagnetic radiation providing a signal corresponding thereto which is shaped in an electrical circuit and provided as an excitation signal to the transmitter. An audio alignment feature is included providing audio indications for alignment of the receiver with the beam of electromagnetic radiation which is to be relayed. The transmitter is directionally adjustable to provide a relayed beam of electromagnetic radiation in a direction different from the received beam. The method includes aligning the receiver with the beam of electromagnetic radiation and converting the received electromagnetic radiation beam to a corresponding electrical signal in the receiver. The method further includes exciting the electromagnetic radiation transmitter with the corresponding electrical signal so that the range of the received electromagnetic radiation beam is extended to include the sum of the ranges of the received and transmitted beams.
