Abstract: The present invention relates to an integrated circuit device comprising an output port for transmitting a data stream and a processor for controlling the transmission of the data stream in accordance with a single-edge nibble transmission protocol. The device also comprises a configuration means for receiving and storing configuration data. The processor is adapted for reporting a plurality of diagnostic statuses via the data stream by transmitting for each diagnostic status a corresponding diagnostic code defined by the configuration data, and wherein the processor is furthermore adapted for reporting the plurality of diagnostic statuses in a diagnostic status reporting order defined by the configuration data.

Abstract: A method of measuring temperature based upon a system of equations applying Stefan-Boltzmann's law and using a measurement value for an object to be measured and an ambient temperature value (Ta) comprises: pre-calculating (200, 202) a first vector (LUT1) and a second vector (LUT2). The first vector (LUT1) is a series of values proportional to received power based upon respective temperature values and in respect of a predetermined generic range of temperatures. The second vector (LUT2) is a series of sensitivity characteristic factor values based upon expected measured temperature values and in respect of a predetermined range of expected object measured temperatures. The first vector (LUT1) and the second vector (LUT2) are used (206) to generate a temporary vector (LUTT) of a series of values limited to the ambient temperature value to solve the system of equations in respect of the measurement value for the object, thereby determining (208) a temperature (To) for the object from the measurement value.

Abstract: A circuit for determining and/or compensating for a measurement error of a sheathed sensor due to a property of a sheath of that sheathed sensor comprises a first and a second terminal for connecting to a pair of sensor signal leads of a sensor element in a sheathed sensor and a voltage measurement circuit. A switching unit controls switching an electrical connection between a first and a second state. A correction measurement circuit generates a correction signal indicative of that a measured current running from the first terminal through the switching unit. A controller receives the measurement and correction signal in both the first and second state, and calculates an error value indicative of the measurement error and/or a sensor readout value that is corrected for the measurement error by taking the measurement and correction signal into account as obtained in both the first and second state.
