Abstract
Abstract Suggested is a circuit for operating computing components ( 10 ), in particular microprocessors, which include a monitoring unit ( 24 ) that transmits a reset signal ( 23 ) to the computing component ( 10 ) as a result of interferences ( 35 ). A varied program sequence is provided in the computing component ( 10 ), depending on a compare signal ( 17, 18 ) provided by a comparator ( 13 ), which compares a signal ( 12 ) with at least one threshold value ( 14, 15 ) that mirrors a condition of a device ( 31 ), which cooperates with the computing component ( 10 ). An adjustment device is planned as a preferred embodiment of a device ( 31 ), wherein the condition corresponds to at least one position range that is preferably located at least near at least one stop position ( 34 ) for the adjustment drive ( 31 ).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
Circuit for operating computing components, in particular microprocessors, with said circuit including at least one reset device, which as a result of interferences transmits a reset signal to the computing component to provide a varied program sequence following the appearance of a reset signal, wherein said sequence is determined in dependence on a compare signal provided by a comparator, and wherein the comparator compares a signal that reflects the present condition of a device, which cooperates with and is controlled by the computing component, with at least one threshold value to provide the compare signal.
Claim 2
Dependent Claim
95 words
Circuit for operating computing components, in particular microprocessors, with said circuit including at least one reset device, which as a result of interferences transmits a reset signal to the computing component to provide a varied program sequence following the appearance of a reset signal, wherein said sequence is determined in dependence on a compare signal provided by a comparator, and wherein the comparator compares a signal that reflects the present condition of a device, which cooperates with and is controlled by the computing component, with at least one threshold value to provide the compare signal.
Claim 3
Dependent Claim
20 words
Circuit according to claim 1 , wherein an adjustment drive operated by an electric motor is provided as the device.
Claim 4
Dependent Claim
28 words
Circuit according to claim 2 , wherein the comparator compares a position signal that corresponds to the position of the adjustment drive with at least one threshold value.
Claim 5
Dependent Claim
19 words
Circuit according to claim 2 , wherein the adjustment drive is arranged in the body of a motor vehicle.
Claim 6
Dependent Claim
26 words
Circuit according to claim 2 , wherein the adjustment drive is arranged in the fuel dosing unit of an internal combustion engine in a motor vehicle.
Claim 7
Dependent Claim
42 words
Circuit according to claim 2 , wherein within at least one preset position range of the adjustment drive, a calibration run is planned if a reset signal appears, for which the adjustment drive performs a complete movement cycle located between stop positions.
Claim 8
Dependent Claim
17 words
Circuit according to claim 6 , wherein the calibration run is suppressed when the compare signal appears.
Claim 9
Dependent Claim
31 words
Circuit according to claim 2 , wherein a position is predetermined with the at least one threshold value, which position is at least near at least one of the stop positions.
Claim 10
Dependent Claim
41 words
Circuit according to claim 1 , wherein a counting device is provided that counts the number of reset signals and, after a predetermined number of counted reset signals provides a selection signal which changes the program sequence in the computing component.
