US Patent:

42660971, May 5, 1981

Filed:

May 14, 1979

Appl. No.:

6/038408

Inventors:

Thomas B. Cannon - Thornton CO
James E. Dalley - Brighton CO
Andrew S. George - Ocean Township, Monmouth County NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H04M 1100

US Classification:

179 2A

Abstract:

The disclosed energy control system employs the serving electronic stored program PBX to regulate the operation of energy consuming devices located throughout a hotel/motel or office building in accordance with one or more modes of operation as offered by an algorithm stored in the PBX memory. This is accomplished by equipping each guest room or office with a control circuit to regulate the operation of the energy consuming devices located in that room. These control circuits are activated by the presence of an audio frequency tone on the telephone line associated with the room. To minimize the impact of this scheme on the traffic capacity of the PBX time division switching network, all activated control circuits are concurrently connected to a single time slot, which supplies the required audio frequency tone.

James Louis Simon - Northglenn CO

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H04M 168

US Classification:

179 99

Abstract:

A privacy circuit for use in a key telephone station set is disclosed. Using only a single relay, the privacy circuit operates to exclude the user from a busy central office line while allowing the user to gain access to an idle line. The privacy circuit is positive acting and cannot be circumvented by manipulating the keys and/or switchhook while at the same time allowing service to continue during a local power failure. Additional circuitry is provided to allow conference connections among key telephone sets equipped with privacy circuits.

Filed:

Dec 23, 1977

Appl. No.:

5/863890

Inventors:

Thomas B. Cannon - Denver CO
John F. O'Neill - Boulder CO

Assignee:

Storage Technology Corporation - Louisville CO

International Classification:

H04J 500

US Classification:

179 15AS

Abstract:

In a time assignment speech interpolation system, a fixed delay between the input speech channel and the transmission facility provides time to generate and transmit a symbol representing the speech channel to which the transmission facility has been assigned. At the remote location, a fixed delay between the transmission facility and the output speech channel provides time in which to detect the symbol and perform the necessary switching.
