Abstract
A sensor arrangement includes an infrared sensor and at least one acceleration sensor. The infrared sensor is configured to detect infrared radiation, and to output infrared image data. The at least one acceleration sensor is configured to detect an instantaneous acceleration of the sensor arrangement, and to output acceleration data. The output of the infrared image data from the infrared sensor is blocked when the instantaneous acceleration of the sensor arrangement exceeds a preprogrammed threshold value.

A sensor arrangement comprising:
- an infrared sensor configured to detect infrared radiation and to output infrared image data;
- and
- at least one acceleration sensor configured to detect an instantaneous acceleration of the sensor arrangement and to output acceleration data,
- wherein the output of the infrared image data from the infrared sensor is blocked when the instantaneous acceleration of the sensor arrangement exceeds a preprogrammed threshold value.
A sensor system, comprising:
- a sensor arrangement including:
- (i) an infrared sensor configured to detect infrared radiation and to output infrared image data;
- and (ii) at least one acceleration sensor configured to detect an instantaneous acceleration of the sensor arrangement and to output acceleration data;
- and
- an evaluation circuit configured to:
- (i) receive the acceleration data output from the at least one acceleration sensor;
- (ii) compare the instantaneous acceleration of the acceleration data with a prescribable threshold value;
- and (iii) block the output of the infrared image data from the infrared sensor for a predetermined period as a function of the comparison.
A method for operating a sensor system including a sensor arrangement and an evaluation circuit, the sensor arrangement having an infrared sensor, and at least one acceleration sensor, the method comprising:
- detecting a value of an instantaneous acceleration of the sensor system with the at least one acceleration sensor;
- comparing the detected value of the instantaneous acceleration with a prescribable threshold value with the evaluation circuit;
- releasing infrared image data of detected by the infrared sensor when the detected value of the instantaneous acceleration has not exceeded the threshold value, or only exceeded the threshold value for a time interval less than a predetermined fixed time interval;
- and
- blocking the infrared image data detected by the infrared sensor, or deactivating the infrared sensor, when the detected value of the instantaneous acceleration has exceeded the threshold value for a time interval greater than the predetermined fixed time interval.
