A system and method provides an Automotive Safety Integrity Level (ASIL) qualifier for Global Navigation Satellite System (GNSS) position and related values. Specifically, hardware platform diagnostics are executed on one or more platforms associated with a GNSS Position Sensor (GNSSPS) that calculates/obtains position and/or related values. Also, a Receiver Autonomous Integrity Monitoring (RAIM) algorithm is executed on the calculated/obtained position and/or related values. If the results both produce a 'good' qualifier, the position and/or related values is assigned an ASIL qualifier of 'good' and may be utilized by an ASIL rated system. If either of the qualifiers is a &#x201c;bad&#x201d; qualifier, the position and/or related values is assigned an ASIL qualifier of &#x201c;bad&#x201d; and cannot be utilized by the ASIL rated system. In addition, the inventive system and method may compute a probability associated with an integrity violation of the RAIM algorithm which may consider the probability of hardware failure.

System and method to provide an ASIL qualifier for GNSS position and related values

A detection system includes an electrochemical sensor. Measurement circuitry is coupled to the electrochemical sensor and configured to measure an electrical characteristic of the electrochemical sensor. A controller is coupled to the measurement circuitry and is configured to provide an indication based on the measured electrical characteristic. The controller is further configured to generate an electrical disturbance to the electrochemical sensor and obtain a sensor recovery profile to provide a diagnostic indication relative to the electrochemical sensor.

Electrochemical detection system with internal life-test

An air flow sensor includes a sensor element and a microcontroller, employing a PWM signal to drive the sensor element. Signals from the sensor element are processed by the microcontroller inside the sensor, resulting in continuous readings of air velocity and air temperature.
