    • Die Erfindung betrifft ein Positionsmessgerät, und ein Verfahren zur Übertragung einer Bewegungsinformation vom Positionsmessgerät zu einer Folgeelektronik (100). Das Positionsmessgerät umfasst eine Positionsmesseinheit (10), eine Bewegungsmesseinheit (20), eine Recheneinheit (30) und eine Schnittstelleneinheit (40). Mit der Positionsmesseinheit (10) sind Positionswerte (P; P n , P n-1 ) von zwei relativ zueinander in einer Messrichtung beweglich angeordneten Objekten messbar. Die Bewegungseinheit (20) dient zur Ermittlung eines Bewegungswertes (v) der zwei relativ zueinander in einer Messrichtung beweglich angeordneten Objekte. Die Positionswerte (P; P n , P n-1 ) und der Bewegungswert (v) sind der Recheneinheit (30) zugeführt, die eine Bewegungsinformation in Form eines Korrekturwertes (K) ermittelt, der geeignet ist, um in einer Folgeelektronik (100) aus einem aktuellen Positionswert (P n ), wenigstens einem vorhergehenden Positionswert (P n-1 ), einer Reglerzykluszeit (T R ), die den zeitlichen Abstand zwischen den Messungen von Positionswerten (P; P n , P n-1 ) angibt, und dem Korrekturwert (K) den Bewegungswert (v) zu berechnen. Dabei ist die Datenwortbreite des Korrekturwerts (K) wesentlich kleiner als die Datenwortbreite des Bewegungswerts (v).

    • According to a first aspect of the preferred embodiment, a three-axis sensor assembly (20) for use in an elastomeric material (21) includes a first pair of sensors (22, 24) disposed along a first pair of respective planes that intersect, the first sensors being adapted to detect a force in a first direction. In addition, the sensor assembly includes a second pair of sensors (30, 32) disposed along a second pair of respective planes that intersect, the second sensors detecting a force in a second direction generally orthogonal to the first direction. Furthermore, in the assembly, the force measured in the first direction is equal to the difference between the outputs of the first sensors (22, 24) and the force measured in the second direction is equal to the difference between the outputs of said second sensors (30, 32). According to another aspect of the preferred embodiment, the sum of the outputs of the first sensors (22, 24) and the second sensors (30, 32) equals a force in a third direction orthogonal to the first and second directions. In another aspect of the preferred embodiment, the first pair of sensors (22, 24) are disposed on first opposed faces of a pyramid-shaped body (42) and the second pair of sensors (30, 32) are disposed on second opposed faces of the pyramid-shaped body (42). In addition, the elastomeric material can be a vehicle tire, and the tire may include a plurality of the sensor assemblies disposed about its perimeter in mutually spaced relationship.

    • An application specific integrated circuit or ASIC (MSC) is connected to a plurality of bridge type sense elements (1-6) for analog multiplexing (10a, 10b, 10c) the outputs from a selected sense element to a common signal conditioning path (1 Of). The bridge type sense elements are biased through an electronically programmable resistor (10d1) to derive a temperature signal. The signal conditioning path provides electronically programmable correction for offset and gain proportional to the sensed condition, e.g., fluid pressure. Complete sensor characterization data provided at the time of manufacture is stored in non-volatile memory (10h) which is downloaded to a host controller (12) on command. The ASIC also includes diagnostic test bridges (BR1, BR2) for diagnosing ASIC faults and a signal diagnostic path (10m) for diagnosing sense element and sense element connection faults. Characterization data downloaded to the host controller enables the controller to mathematically correct remaining temperature, condition (e.g., pressure) and diagnostic signal errors.
