Abstract
A system generating an electrical signal based on at least one physical quantity, includes sensor units each generating an individual electrical signal in response to the at least one physical quantity, a selecting unit selecting a first number of sensor units from the sensor units and outputting a first combined electrical signal based on the first number of sensor units, and a calibrating unit determining a second number of sensor units to be selected based on the first combined electrical signal.
Claims18
A system comprising:
- a joint terminal;
- a first group of sensor units coupled in series, wherein a first sensor of the first group is coupled to the joint terminal;
- a second group of sensor units coupled in series, wherein a first sensor of the second group is coupled to the joint terminal;
- a selecting unit coupled to the first group of sensor units and the second group of sensor units, wherein the selecting unit is configured to:
- select a first number of serially connected sensor units from the first group of sensor units and the second group of sensor units;
- and
- output a signal from the first number of sensor units;
- and
- a calibrating unit coupled to the selecting unit and configured to:
- receive the signal;
- compare the signal to a range value;
- and
- in response to the signal being outside the range value, output a selection signal to the selecting unit, wherein in response to the selection signal, the selecting unit is configured to select a second number of sensor units from the first group of sensor units and the second group of sensor units.

A method comprising:
- selecting, by a selecting unit coupled to a first group of sensor units and a second group of sensor units, a first number of serially connected sensor units from the first group of sensor units and the second group of sensor units, wherein a first sensor of the first group of sensor units is coupled to a joint terminal and a first sensor of the second group of sensor units is coupled to the joint terminal;
- outputting, by the selecting unit, a signal from the first number of sensor units;
- and
- receiving, by a calibrating unit, the signal;
- comparing, by the calibrating unit, the signal to a range value;
- and
- in response to the signal being outside the range value:
- outputting, by the calibrating unit, a selection signal coupled to the selecting unit;
- receiving, by the selecting unit, the selection signal;
- and
- based on the selection signal, selecting, by the selecting unit, a second number of sensor units from the first group of sensor units and the second group of sensor units.
