    Abstract: A light-guide assembly and an access control system are provided. The light-guide assembly is used as an interface for touch input. The light-guide assembly includes a light-guide element and a light source disposed on a lateral surface of the light-guide element. The light source emits a first light with a first wavelength. The light-guide element has an upper surface, a lower surface, and an inner layer that is made of a light-transmissive material. The first light enters the light-guide element through the lateral surface and propagates inside the light-guide element for reacting to the touch event occurring on the upper surface. A verification data used in an access control system is formed when the touch event is sensed and identified. A light-activation element of the assembly activates the first light propagating inside the light-guide element and produces a second light that is used to provide a visual effect.

    Abstract: There is provided a pixel circuit for performing analog operation including a photodiode, a first temporal circuit, a second temporal circuit and an operation circuit. Within a first interval, the photodiode detects first light energy to be stored in the first temporal circuit. Within a second interval, the photodiode detects second light energy to be stored in the second temporal circuit. Within an operation interval, the first temporal circuit outputs a first detection signal having a first pulse width according to the first light energy and outputs a second detection signal having a second pulse width according to the second light energy for being calculated by the operation circuit.
