US Patent:

7031436, Apr 18, 2006

Filed:

Apr 9, 2003

Appl. No.:

10/410697

Inventors:

William Garey - Arlington TX, US
Vinh Le - Arlington TX, US

International Classification:

H04M 11/00

US Classification:

379 37, 379 40, 379 39

Abstract:

A telephone security device is built into a telephone unit. The device includes a sensor to detect an intrusion into the area in which the telephone is located. Upon detection of an event, the device places the telephone off hook, and triggers the redial feature of the telephone. This causes the telephone to redial the last number that had been called. The telephone then remains in the off hook condition for a delay interval to allow the recipient of the call to listen, via the telephone, for any sounds indication that an actual intrusion has occurred. In order to arm the security device, the user simply dials the number that is the intended recipient of the call, hang up, and switch on the sensor. Detection of a security event will then cause the last dialed number to be redialed.

Inventors:

Monty F. Webb - Irving TX
Vinh Q. Le - Irving TX
Elmer L. Turner - Irving TX

Assignee:

Teccor Electronics, Inc. - Irving TX

International Classification:

H01L 2131

US Classification:

437 6

Abstract:

A two-terminal, bidirectional semiconductor trigger switch is provided. The trigger switch is a relatively sensitive multilayer semiconductor breakover device that switches on fully when its breakover voltage is reached. The design of the trigger switch allows its breakover voltage point to be readily adjustable during fabrication of the device. The semiconductor trigger switch is particularly suited to provide a low voltage trigger for a TRIAC. The trigger switch is connected in series with the gate of the TRIAC and mounted on the gate lead to provide a unitary, three-terminal device incorporating the TRIAC/trigger switch combination.

Teccor Electronics, Inc. - Irving TX

International Classification:

H04B 346

US Classification:

379 26

Abstract:

A telephone maintenance termination unit utilizes a low voltage, bidirectional trigger switch for performing diagnostic functions on a telephone line. The trigger switch provides low voltage, low current triggering in conjunction with a high holding current requirement. The trigger switch may comprise either two silicon controlled rectifiers connected in inverse parallel relationship with their gates connected, a bidirectional diffused PNPN semiconductor device, or an NPN semiconductor device, any one of which is used to trigger a power control TRIAC. In another embodiment, the switching device may be a two-terminal, unitary semiconductor device incorporating the functions of both the TRIAC and the bidirectional trigger switch.

International Classification:

G06F 1300

US Classification:

709213

Abstract:

A high speed data communications method and system is provided whereby multiple groups of software interfaces are used to link a Distributed Systems Services Unit to a Network Provider which connects to an Input/Output Interface Module which relates to external interfaces of a Network. The interfaces permit the capability of buffer sharing and lock pool sharing, in addition to improved Connection Library Element Interfaces which reduce the overhead that was previously required and further enables faster data transfer operations with reduced latency.

International Classification:

G06F 1516

US Classification:

709227

Abstract:

A Connection Library Interface for a Process-Intercommunication Manager and a Process-Intercommunication Element provides an improved interface generating enhancements in data communication operations between a Network Provider and a Ports Unit which is part of the Master Control Program of a computer system. An improved method of data transfer involves a Distributed Systems Service/Application unit which operates through the Ports File of a Master Control Program, then uses Connection Library Interfaces to communicate with a Network Provider for data transfer to and from underlying interfaces.
