Abstract
A receiver compensation system and method to operate the receiver compensation system are disclosed. The compensation sensor system includes at least one receiver and at least one control loop. The method to operate the receiver compensation system is characterized in that the receiver is adjusted in its sensitivity by a control signal such that in the case of changes of an input received by the receiver, a control signal of the control loop resets an associated receiver output signal, except for a control error. Further, at least one other signal of the control loop represents or contains a measurement of the change of the input received by the receiver.
Claims18
A method to operate a compensation sensor system comprising at least one receiver D and at least one control loop, said method characterized in that:
- the at least one receiver D is readjusted in its sensitivity by a control signal S3 such that,
- in the case of changes of a physical value received by the receiver D, the first control signal S3 of the at least one control loop resets at least one associated receiver output signal S1 except for a control error, and
- at least a control signal S4 of the control loop represents or contains a measurement of the change of the physical value.
A compensated sensor system comprising at least one receiver D and at least one control loop, said compensated sensor system characterized in that:
- the at least one receiver D is readjusted in its sensitivity,
- in case of changes of a physical value received by said receiver D the control loop resets at least one related receiver output signal S1 except for a control error by the at least one control loop using at least one control signal S3, and
- at least one other control signal S4 of the control loop represents or contains a measurement of the change of the physical value.
A method of operating a compensation sensor system comprising at least one receiver and at least one control loop, said method including the steps of:
- receiving a variable receiver input signal at a first level by the receiver,
- adjusting the sensitivity of the receiver via a first control signal such that a receiver output signal is at an initial receiver output signal value,
- receiving the variable receiver input signal at a second level by the receiver, the second level being different from the first level, and
- readjusting the sensitivity of the receiver via the first control signal such that the receiver output signal is again adjusted to the initial receiver output signal value, except for a control error, and a control loop output signal contains or represents a measurement of a difference between the first level and the second level of the variable receiver input signal.
