Abstract
The device has an input element, which can be used for resetting the device. The input element has at least one first photodiode arranged in series to at least one second photodiode. A voltage is applied over the photodiodes. When the user blocks light to only the second photodiode, the voltage at the interconnection between the photodiodes changes, which can be used to trigger the input element. The input element has low power consumption and high reliability.
