20030056677, Mar 27, 2003

Filed:

Sep 20, 2001

Appl. No.:

09/957087

Inventors:

James Griggs - Bradenton FL, US
Scott Gagnon - Dover FL, US
Clinton Boyd - Orlando FL, US
J B Canterberry - Apollo Beach FL, US

International Classification:

F42B003/18
F42C015/00

US Classification:

102/202100

Abstract:

A frequency addressable ignitor control device utilizes electronic bandpass filters tuned to a unique center frequency and bandwidth for each ignitor. Energy generated by the system's controller comprises one or more narrow pulses whose center frequency corresponds to one or more bandpass filter/ignitor assemblies and sufficient energy for activation. A plurality of bandpass filter/ignitor assemblies are connected in parallel in the system. The controller generates electrical pulses of different frequencies transferred to the plurality of bandpass filter/ignitor assemblies via a two wire ignitor bus. Bandpass filter/ignitor assemblies whose filter allows sufficient energy to pass to an ignitor bridge element initiates the ignitor's explosive charge. The controller generates energy to the ignitor with appropriate sequence of frequencies and delays resulting in the desired detonation of appropriate individual bandpass filter/ignitor assemblies in the desired sequential order each with the desired delays.

10/262975

Inventors:

John Fisher - Lutz FL, US
James Griggs - Bradenton FL, US
James Sowers - Lakeland FL, US
Timothy Ilyes - Lakeland FL, US

International Classification:

F42C001/00
C06C005/00

US Classification:

102/200000, 102/215000

Abstract:

A smart igniter bus system has a repeater connected by a bus to a controller, and one or more smart igniters connected by the bus to the repeater so that the repeater is between the smart igniters and the controller. The repeater receives data transmitted on the bus by the controller and processes the signal sent by the controller with onboard logic. Utilizing the onboard logic, the repeaters are preprogrammed to rebroadcast control signals sent by the controller or to only rebroadcast selected signals, or to generate and transmit new command signals.

Appl. No.:

8/933596

Inventors:

James Woodhouse Griggs - Bradenton FL
Robert Perry Pettypiece - Lakeland FL

Assignee:

Breed Automotive Technology, Inc. - Lakeland FL

International Classification:

B60R 2132

US Classification:

280735

Abstract:

A vehicle occupant sensing apparatus is provided for use with an associated vehicle having a seat. The vehicle occupant sensing apparatus includes a first range measurement system for sensing a first distance from the first range measurement system towards a first area of the seat, a second range measurement system for sensing a second distance from the second range measurement system toward a second area of the seat and a controller. The controller includes operating means for operating the first and second range measurement systems and determining means for determining if an object is located on the seat in response to the first and second distances. In this way it can be determined if a child seat is present on the seat of the associated vehicle and further whether it is a front facing or back facing child seat.

Abstract:

A smart ignitor control system has communications output electronic circuitry and communications input electronic circuitry. The communications output electronic circuitry generates output serial clock, data, and handshaking signals for communication with a master ASIC that is adapted to communicate with a smart ignitor. The communications input electronic circuitry inputs data and handshaking signals from a master ASIC. Smart ignitors are in circuit communication with the master ASIC via an ignitor bus. Optionally, additional circuitry digitizes analog voltages and waveforms from the ignitor bus and transmits the digitized data to an electronic information processor.
