Patent Number: 7,232,984

Title: Sensor with improved gain-setting capability

Abstract: A method of calibrating a sensor such as a photodetector, and device capable of employing that method, are disclosed. The method includes shining light upon a photosensitive device of the photodetector, receiving a first signal from an operator, and increasing a gain of the photodetector. The method also includes discontinuing the shining of the light upon the photosensitive device after the gain has been increased, receiving a second signal from an operator, and decreasing the gain so that the gain is not excessive.
