Fail-Safe Apparatus And Method For Disposal Of Automobile Pyrotechnic Safety Devices
US Patent:
7930082, Apr 19, 2011
Filed:
May 20, 2008
Appl. No.:
12/154122
Inventors:
David Eiswerth - Wixom MI, US
Ganesh Ram Venkatraman - Canton MI, US
Jorgen Ingvar Carlsson - Åby, SE
Colm Boran - Novi MI, US

Assignee:
Autoliv ASP, Inc. - Ogden UT
International Classification:
B60R 21/30
G06F 17/00
G06F 17/00
US Classification:
701 45, 701 46, 701 34, 280738
Abstract:
A method for disposing of a pyrotechnic safety device includes providing an electronic control unit having a primary control unit and an auxiliary control unit. The auxiliary control unit includes a safing mode and a scrap mode, and operates in the safing mode in an initial state. The auxiliary control unit is switched from the safing mode to the scrap mode when the primary control unit sends a first predetermined signal. The auxiliary control unit is armed only if it receives a second predetermined signal from the primary control unit while the auxiliary control unit is operating in the scrap mode. The primary control unit sends the first and second predetermined signals to the auxiliary control unit based on signals the primary control unit receives from an external source. The primary control unit then disposes of a pyrotechnic safety device (PSD) by sending a deployment signal to the PSD based on another signal received from the external source.
Remote Sensor Network System With Redundancy
US Patent:
2007011, May 24, 2007
Filed:
Nov 23, 2005
Appl. No.:
11/287134
Inventors:
Colm Boran - Novi MI, US
Myron Senyk - Rochester Hills MI, US
David Eiswerth - Wixom MI, US

International Classification:
B60Q 1/00
G08B 29/00
B60L 1/00
G08B 29/00
B60L 1/00
US Classification:
340436000, 340507000, 307010100
Abstract:
A multi-sensor network having a plurality of receivers and sensors connected to a common communication line is provided. A controller will activate one of the plurality of receivers, thereby allowing one of the plurality of sensors to transmit data to the communication line. The plurality of sensors each individually have a logic device preventing more than one sensor from transmitting data in a given time interval.
Auto-Address Multi-Sensor Network
US Patent:
2007019, Aug 23, 2007
Filed:
Feb 21, 2006
Appl. No.:
11/358249

International Classification:
G06F 17/00
US Classification:
701001000, 701045000
Abstract:
A sensor network and method of initializing the sensor network is shown. The network includes a receiver and sensor assemblies each having a first and second pin. The receiver and the sensor assemblies are connected in a daisy chain type configuration. Based on the amount of current passing from the first pin to the second pin of each sensor assembly, the sensor assemblies determine a discrete time signal window to output a current modulated signal to the receiver.
Delta-Difference Amplifier Circuit For Restraint Control Module
US Patent:
2020024, Jul 30, 2020
Filed:
Jan 30, 2019
Appl. No.:
16/262638
Inventors:
- Southfield MI, US
Stuart Koch - West Bloomfield MI, US
David Eiswerth - Wixom MI, US
Stuart Koch - West Bloomfield MI, US
David Eiswerth - Wixom MI, US
International Classification:
G01R 31/00
H03F 3/45
H03F 3/45
Abstract:
A system for diagnosing a squib loop in a restraint control module. The system may include a first amplifier, a capacitor, a second amplifier. The first amplifier may have a first input connected to a first side of the squib and a second input connected to a second side of the squib. The output of the first amplifier may generate an output voltage corresponding to the voltage drop across the squib. The capacitor may be connected in series with the output of the first amplifier and the output of the first amplifier may be connected to a first side of the capacitor. The second amplifier having a first input connected to a second side of the capacitor. A second input of the second amplifier may be connected to a reference voltage. The second amplifier may be configured with a feedback loop to generate a gain output.
