Patent ID: 8339169

Claim:
A device for capturing and transferring a measured value, the device comprising a logic circuit having a first input port, a second input port, a third input port and a first output port, and a feedback path which provides a connection between the first output port and the third input port and which is configured to feed back a change in the state of the first output port to the third input port delayed by a time value, wherein the feedback path comprises an impedance which is configured to change in response to the measured value and consequently change the time value of the feedback in the feedback path, and wherein the logic circuit is configured to set a first or a second operating state depending on whether a first or a second logic state is present at the second input port, wherein in the first operating state a change of a logic state at the first input port triggers a change of a logic state of the first output port and a change of a logic state at the third input port does not trigger a change of the logic state at the first output port, and in the second operating state a change in the logic state of the third input port triggers a change of the logic state of the first output port.
