Abstract: A modular sensor assembly in which a sensing module may be packaged and provided separately from a signal processing module and which, in some applications, may facilitate disposal and/or replacement of the sensing module when exposed to a “dirty” or “contaminated” environment without requiring disposal and/or replacement of the entire sensor assembly. In certain applications, the sensing module may include at least one transducer or sensor and a local memory containing a set of conditioning coefficients. The sensing module may be removably coupled to a signal processing module which, in some cases, may be configured to download the set of conditioning coefficients stored in the local memory of the sensing module, and to use the set of conditioning coefficients to produce a substantially linearized output signal.

Abstract: A physical quantity sensor 1 comprises a driving circuit 4 that drives a sensor element based on a reference signal; the sensor element 3 that is driven by the driving circuit 4 to convert an externally applied physical quantity to an electrical signal; and an amplifier circuit 5 that amplifies an output signal of the sensor element 3. The driving circuit 4 controls a driving signal, which drives the sensor element, based on the reference signal so that the driving signal is at a fixed level, and the amplifier circuit 5 has a gain characteristic that amplifies the output signal in a direction reverse to a direction in which the reference signal varies or the driving signal of the driving circuit varies. This configuration allows the physical quantity sensor to reduce output level variations in the sensor output against signal level variations in the reference signal and to make the sensitivity constant.

Abstract: A circuit and a method to measure continuously the resistance of variable resistors in series as e.g. potentiometers within a sensor, used for e.g. a joystick, has been achieved. The voltage across said sensor comprising any number of variable resistors is stabilized. A constant current source is providing a minimum current through said sensor. A variable current source is used to zoom variations of current through the sensor caused by variations of resistance of the sensor. Said variable current is mirrored and by measuring the voltage across a shunt resistor the total resistance of the sensor is identified. Using ports between each of the resistors, voltages can be measured representing the resistance of each of the variable resistors using known equations of voltage dividers. Any number of variable resistors can be used in the circuit invented.
