Filed:

Aug 17, 2005

Appl. No.:

11/206275

Inventors:

Christopher Wayne Fox - San Antonio TX, US

Assignee:

Common Credential Systems, L.L.C. - Houston TX

International Classification:

G06F 9/00

US Classification:

713172, 713171, 713175, 713185

Abstract:

A system is provided for upgrading a legacy security system having a legacy control panel and a legacy card reader, without interfering with legacy system operation. A new control panel is installed between the legacy card reader and the legacy control panel. Also, a new token reader is installed next to the legacy card reader and connected to the new control panel. The new control panel passes credentials it receives from the legacy card reader to the legacy control panel, avoiding interference with legacy system operation. When the new control panel receives credentials from the new token reader, it evaluates them against an access rights list administered independently of the legacy access rights list. When the new control panel determines that an access request should be granted, it sends a memorized legacy credential associated with full access rights to the legacy control panel, causing it to open the door.

Appl. No.:

13/559241

Inventors:

Peter R. Pettler - Miami FL, US
Christopher Fox - San Antonio TX, US

International Classification:

H04B 3/54

US Classification:

375257

Abstract:

A system for transmitting communication signals, the system comprising an injector circuit connected to a powered circuit conductor and configured to modulate a power signal with a direct current voltage offset, the direct current voltage offset being within a range that causes approximately 1 percent or less total harmonic distortion of the power signal; and a decoder connected to the powered circuit conductor and a load, the decoder configured to demodulate the direct current voltage offset to control the load. A method for transmitting communication signals, the method comprising modulating a power signal on a powered circuit conductor with a direct current voltage offset, the direct current voltage offset being within a range that causes approximately 1 percent or less total harmonic distortion of the power signal; and demodulating the direct current voltage offset to control a load.

Appl. No.:

8/283832

Inventors:

Alan C. Heller - San Antonio TX
Steven Springmeyer - Bellevue WA
Christopher W. Fox - Englewood CO

Assignee:

Precision Tracking FM, Inc. - Dallas TX

International Classification:

H04Q 100

US Classification:

34082535

Abstract:

An object location, control, and tracking system is implemented using an object identifier variable-based protocol such as SNMP. Infrared sensors, touch memory ports, passive infrared sensors, and external device controllers are all accessed using object identifier variables and in this way stimuli events are reported to a computer on the network, and the external devices are controlled responsive to the stimuli.

Assignee:

Precision Tracking FM, Inc. - San Antonio TX

International Classification:

G01B 1100
G01B 900
G01C 332

US Classification:

356375

Abstract:

An optical location system for locating the position of a moving object in a defined area. An optical transmitter is attached to the moving object. A stationary receiver has a number of sensors for receiving a signal from the transmitter. One sensor has a field of view of the entire area. Other sensors have partially blocked fields of view, with the blocking being accomplished with nonopaque strips of decreasing width. These strips are arranged so that the detection or nondetection of light by the sensors can be digitally coded in a manner that corresponds to sections of the area.

Assignee:

Precision Tracking FM, Inc. - San Antonio TX

International Classification:

H04B 1000

US Classification:

359155

Abstract:

The method for receiving and transmitting optical data and control information to and from remotely located receivers and transmitters in an optical location system. Wherein, the locator system tracks and locates the position of a main object having an attached transceiver. This transceiver has stored in memory selected identifying information about the object to which the transceiver is attached. The selected identifying information was received by the transceiver over it's 1-wire interface from a touch memory.
