ELECTRONIC DETECTING APPARATUS
First Claim
1. An electronic detecting apparatus for detecting an output of an external device, the apparatus comprising a detector operative to detect a variable relating to the output of the external device, and a controller operative to receive a detector signal from the detector indicative of an initial non-steady state value of the detected variable and further operative to process the detector signal to generate a processed signal, the controller combining the detector signal and the processed signal to generate an output signal indicative of a future steady state value of the variable.

Abstract
An electronic detecting apparatus is provided for detecting an output of an external device such as a light emitter. The apparatus comprises a detector operative to detect a variable relating to the output of the external device, and a controller operative to receive a detector signal from the detector indicative of an initial non-steady state value of the detected variable. The controller is further operative to process the detector signal to generate a processed signal, the controller combining the detector signal and the processed signal to generate an output signal indicative of a future steady state value of the variable. The apparatus thus speeds up the time taken for the steady state value of the variable to be determined.
