Filed:
Oct 22, 2002
Appl. No.:
10/277797
Inventors:
David L. Corkum - Attleboro MA
Keith W. Kawate - Attleboro Falls MA
Thomas R. Maher - Rehoboth MA
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01R 2702
US Classification:
324610, 324725, 324648, 324706
Abstract:
An ASIC ( ) conditions two independent outputs (VINM, VINP) of a full Wheatstone piezoresistive bridge ( ) in separate conditioning paths. Each path is provided with a bridge supply voltage (VHB , VHB ) which can serve as a temperature related input signal to respective offset and gain compensation control circuits. The half bridge outputs are inputted to respective amplifiers (U , U ) along with a selected percentage of the temperature dependent bridge supply voltage. The outputs of the amplifiers provide a signal proportional to respective half bridge output voltage. In one embodiment, the output of the amplifier (U ) in one conditioning path of one half bridge is connected to the input of an amplifier (U ) in the other conditioning path to provide a signal in the one path proportional to the Wheatstone bridge differential output voltage and in the other path a signal proportional to the Wheatstone half bridge output voltage. In another embodiment, the temperature dependent bridge supply voltage is multiplexed for a selected time upon power-up to an amplifier (U ) which normally receives an input from one of the bridge outputs.

Keith W. Kawate - North Attleboro MA
David L. Corkum - Attleboro MA
Thomas R. Maher - Rehoboth MA
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01R 3100
US Classification:
324500, 324526, 324610, 324706, 324705
Abstract:
An in-range fault detection system for a full wheatstone bridge element ( ) having piezoresistive elements (R , R , R , R ) has bridge outputs (INP, INM) connected to measuring means in the form of a first circuit portion ( ) to provide a common mode voltage (V ). A second circuit portion ( ) is used to provide a centering voltage (C*V ) equal to the common mode voltage at the time of sensor calibration and a third circuit portion ( ) is used to provide a small window voltage (W*V ) which is a fraction of bridge voltage. The value (W*V ) is subtracted from (C*V ) at a first summing circuit (SUM ) and added to (C*V ) at a second summing circuit (SUM ) and the results are each compared to the common mode voltage by comparators (Q , Q ) which are then determined to be within or without a window of valid values by an OR gate (Q ).

Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
G01R 1710
US Classification:
324526, 324610, 324725, 73 111, 702 88
Abstract:
A full Wheatstone bridge sensor has conditioning electronics of an ASIC connected thereto. Two independently controlled diagnostic switches (S1, S2) in the ASIC are commonly connected to one of the bridge output nodes. The first diagnostic switch connects first resistor between the bridge output node and bridge supply voltage and the second diagnostic switch connects a second resistor between the bridge output and bridge ground. The first diagnostic switch closes during a first diagnostic waveform phase and opens during all other phases of operation. The second diagnostic switch closes during a second and third waveform phase and opens during all other phases of operation. The diagnostic waveforms are used to test major signal conditioning and fault reporting paths of the ASIC.

Potentiometric Dac Having Improved Ratiometric Output Voltage Stability

US Patent:
6249239, Jun 19, 2001
Filed:
Nov 5, 1999
Appl. No.:
9/435299
Inventors:
David L. Corkum - Attleboro MA
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
H03M 178
US Classification:
341154
Abstract:
A potentiometric digital to analog converter includes switches to electrically connect a string of n resistors between two voltage supplies to charge a first capacitor (C. sub. 1) through a first tap and store the charge and then to reverse the electrical connections of the string to the two power supplies to charge a second capacitor (C. sub. 2) through a second tap connected at an inverse location symmetrical about the average voltage of the voltages at the supply connectivity switches and store the charge of the second capacitor. The voltage (V. sub. A, V. sub. B) on the two capacitors is then averaged to provide a ratiometric output voltage which is insensitive to the drift of values of the string of resistors.

Signal Processing During Fault Conditions

US Patent:
2012029, Nov 15, 2012
Filed:
May 10, 2011
Appl. No.:
13/104077
Inventors:
David L. Corkum - Attleboro MA, US
International Classification:
G06F 11/07
US Classification:
714 49, 714E11024, 714E11025
Abstract:
A system is configured to monitor a received signal. In response to detecting a fault condition associated with the received signal, the system sets a fault status indicator to indicate occurrence of the detected fault condition. The system sets a state of the fault status indicator for at least a predetermined amount of time to indicate occurrence of the detected fault condition. Subsequent to setting the fault status indicator for at least the predetermined amount of time to indicate the occurrence of the detected fault condition, the system monitors integrity of the signal again. After the predetermined amount of time, in response to detecting that there is no longer a fault associated with the monitored signal, the system modifies the fault status indicator to indicate absence of the fault condition.
