Patent number: 9643558Abstract: A system for detecting a mismatch between first and second input signals includes first and second analog-to-digital converters, a time-division multiplexing circuit, first and second processors, a time-division de-multiplexing circuit, and a gating circuit. The first processor includes a first sinc filter, a first trimmer, a first infinite impulse response (IIR) filter, and a first high pass filter (HPF). The second processor includes a second sinc filter, a second IIR filter, and a second HPF. A bandwidth of the second IIR filter and the second HPF is greater than a bandwidth of the first IIR filter and the first HPF. A transfer function of the first IIR filter and the first HPF uses floating-point coefficients and a transfer function of the second IIR filter and the second HPF uses coefficients that are an integral power of two.Type: GrantFiled: February 18, 2015Date of Patent: May 9, 2017Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Siddhartha Gopal Krishna, Russell J.

Patent number: 7003384Abstract: A method and apparatus (20) for recognizing and determining a location of an object (40) in an area of interest (31) comprises an imaging device (61) for obtaining an image of the area of interest. At least three identifying marks (104) are located at predetermined positions in the area of interest (31). The apparatus (20) also comprises a memory (78) in which the predetermined positions of the at least three identifying marks (104) are stored. A controller (80) determines whether the imaging device (61) is calibrated properly by analyzing the image obtained by the imaging device to determine whether positions of the at least three identifying marks (104) in the obtained image correspond to the predetermined positions stored in the memory (78). The controller (80) is also adapted to determine whether a view of the area of interest (31) from the imaging device (61) is obstructed.Type: GrantFiled: October 24, 2003Date of Patent: February 21, 2006Assignee: TRW Automotive U.S. LLCInventors: Yun Luo, Jon K.

Patent number: 6448671Abstract: A distributed vehicle safety system (10) includes a plurality of devices (16), each of which performs a function associated with safety at a vehicle (12). A bus (18) conveys communication regarding the devices (16). An isolation device (28) is associated with each device (16) and electronically isolates one of the devices from the bus (18) upon occurrence of a fault condition. Preferably, the system (10) includes a plurality of control circuitries (26), each for controlling a respective one of the devices (16), and the control circuitry is isolated with the associated device (i.e., each control circuitry/device arrangement is isolated). In one embodiment, a plurality of bus connector/bus plug mated pairs (20 and 22) connects the plurality of control circuitry/device arrangements (26 and 16) to the bus (18). Each connector/bus plug pair (20 and 22) includes a switch (e.g.Type: GrantFiled: August 5, 1999Date of Patent: September 10, 2002Assignee: TRW Inc.Inventors: Jon K. Wallace, Russell J. Lynch

Patent number: 6249730Abstract: A vehicle occupant protection system (10) includes an actuatable device (e.g., 20) for protecting a vehicle occupant (12). An accelerometer (e.g., 50) and a crash determination portion (66) of a controller (56) derive a first metric indicative of a vehicle crash condition. A Z-axis accelerometer (54) and a safing portion (50) of the controller (38) derive a second metric indicative of a vehicle vertical acceleration characteristic. The controller (66) actuates the device (e.g., 16) to protect the occupant (12) in response to the first metric indicating a vehicle crash condition and the second metric exceeding a predetermined threshold. Preferably, the system (10) includes a second device (e.g., 18) and another accelerometer (e.g., 58) and another crash determination portion (72) of the controller (56) to derive a third metric indicative of a vehicle crash condition. The controller (66) actuates the device (e.g.Type: GrantFiled: May 19, 2000Date of Patent: June 19, 2001Assignee: TRW, Inc.Inventors: Farid Khairallah, Scott E. Kolassa, Russell J. Lynch, Keith R.

Patent number: 6212457Abstract: A distributed vehicle safety system (10) and an associated method provide for connection of a plurality of devices (14). Each of the devices (14) performs a function associated with protection of a vehicle occupant. A communication bus (16) conveys communication for the devices (14). The bus includes first and second conductors (18A and 18B). A first portion (subset K) of the devices (14) are daisy-chain connected, with respect to each other, along one (e.g., 18A) of the conductors of the bus (16). A second portion (subset L) of the devices (14) are connected in parallel across the first and second conductors (18A and 18B) of the bus (16). The second portion (subset L) contains at least one and preferably several devices (14).Type: GrantFiled: August 5, 1999Date of Patent: April 3, 2001Assignee: TRW Inc.Inventors: Keith R. Miciuda, Russell J. Lynch, Jon Kelly Wallace

Patent number: 6188314Abstract: A system (10) conveys energy and communication between a master (16) and a plurality of slaves (18, 20), via a bus (14). A power/voltage transmitter (44) of the master (16) provides electrical energy, having a voltage, onto the bus (14) to power the slaves (18, 20). The power/voltage transmitter (44) adjusts voltage past a predetermined threshold to provide a message frame and modulating voltage during the message frame to convey messages to the slaves (18,20). Voltage receivers (58, 64), at each slave (18, 20), detect the voltage modulations to discern messages from the master (16) during the message frame. Current transmitters (56, 62), at each slave (18, 20), modulate current during the message frame to convey messages to the master (16). The current transmitters (18, 20) utilize the modulation of voltage of the electrical energy to clock modulation of current. A current receiver (48) of the master (16) detects current modulations to discern messages from the slaves (18, 20).Type: GrantFiled: February 3, 1999Date of Patent: February 13, 2001Assignee: TRW Inc.Inventors: Jon Kelly Wallace, Russell J.

Patent number: 6104308Abstract: A communication system (10) for use in a vehicle occupant restraint system (12). A central controller (14) is connected to a plurality of restraint devices (16) by a power and communication conductor (20). A signal function (28), via a voltage modulator (30), of the central controller (14) sequentially outputs voltage modulation messages to the restraint devices (16) on the conductor (20). The application sequence of the voltage modulation messages corresponds to a predetermined sequence of the restraint devices (16). A signal function (40), via a current draw modulator (42), in each of the restraint devices (16) outputs current modulation messages to the central controller (14) on the conductor (20). The application of the current modulation message from each respective restraint device (16) coincides with the outputting of a voltage modulation message from the central controller (14) to another specified one of the restraint devices.Type: GrantFiled: July 3, 1997Date of Patent: August 15, 2000Assignee: TRW Inc.Inventors: Jon Kelly Wallace, Russell J.

Patent number: 6070687Abstract: A vehicle occupant restraint system (10) has an anti-theft feature. A restraint device (e.g., 12) of the system (10) is actuatable for restraining a vehicle occupant. The restraint device (12) has an identity associated with the system (10). A central controller (40) communicates with the restraint device (12) and controls actuation of the restraint device. The central controller (40) has a theft deterrent function (52) for discerning the identity of the restraint device (12) and for determining whether the identity of the restraint device corresponds to the system (10). The theft deterrent function (52) provides a signal (60) indicative of the determination.Type: GrantFiled: February 4, 1998Date of Patent: June 6, 2000Assignee: TRW Inc.Inventors: Jon Kelly Wallace, Russell J.
