摘要: An information processing apparatus, an information processing method, and a program, the information processing apparatus and the information processing method appropriately combining observation values of a plurality of sensors according to noise characteristics of the plurality of sensors and a condition for the observation values. An Allan variance is calculated as the characteristics of each of the plurality of sensors. A time window length for an Allan variance is specified as a condition used when the observation values of the plurality of sensors are combined. A weight for each of the plurality of sensors is calculated such that a sum of the Allan variances for the specified time window length is smallest. The respective observation values of the plurality of sensors are combined using a sum of products of the observation values of the plurality of sensors and the weights calculated for each corresponding sensor of the plurality of sensors.

摘要: A sensor assembly includes a sensor element and at least two control units, each having an evaluation and control unit and an energy source. In a first control unit, a first evaluation and control unit is connected to a first energy source, and in a second control unit, a second evaluation and control unit is connected to a second energy source. The at least two control units and the sensor element are interconnected by at least one separate interconnection unit. Each interconnection unit connects a first connection of an associated sensor element to the first energy source and/or to the second energy source. A second connection of the sensor element is earthed. A sensor current flowing through the sensor element is modulated at least with information about a detected measured variable. The first evaluation and control unit and/or the second evaluation and control unit evaluate(s) the detected sensor current.

摘要: A measuring transducer for converting an analog electrical input signal into an analog electrical output signal. The measuring transducer contains a detection apparatus for detecting an analog electrical input signal within a predetermined input measurement range, wherein the input measurement range of the measuring transducer is divided into n adjustable partial input measurement ranges and the output range of the measuring transducer is divided into n adjustable partial output ranges, where n is greater than 1. Further, an apparatus is provided for recognizing the partial input measurement range in which the detected analog electrical input signal lies. An imaging apparatus maps each partial input measurement range to a separate partial output measurement range of the n partial output measurement ranges. Another apparatus converts the detected analog electrical input signal into the associated analog electrical output signal depending on the recognized partial input measurement range.

摘要: Disclosed is a method for driving a processor of an electronic box mounted on a vehicle wheel, transmitting operating parameters of the wheel for implementation of a specific application by a central unit. This includes defining, for each specific application, the physical quantities liable to affect the relevance of the operating parameters, and ranges of measured values corresponding to conditions for obtaining relevant values of the operating parameters. Also included is a procedure for acquiring and transmitting the operating parameters consisting of a succession of transmission windows, during each of which the physical quantities selected for the application are measured, it is checked whether the conditions for obtaining relevant values of the operating parameters are met. If so, at least one value of each parameter is acquired and transmitted, while assigning to this value a datum attesting to the relevance of the latter, and then the transmission window is closed.

摘要: A method for assessing the condition of a sensor includes applying a diagnostic signal to the sensor using a controller and receiving a dynamic output response. The dynamic output response includes a voltage transient and return to a baseline sensor output voltage. The dynamic output response is thereafter compared to a reference output response, and condition of the sensor is indicated as unreliable if the dynamic output response differs from the reference output response by a predetermined amount for a dynamic output response output parameter.
