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: A robot cleaner comprises a first light source, an optical sensor, a processing circuit and a second light source. The first light source emits first light. The optical sensor senses first optical data generated according to the first light. The processing circuit computes a height or an overhang height of an obstacle based on the first optical data. The second light source emits second light. The optical sensor senses second optical data generated according to the second light. The processing circuit determines whether the obstacle exists in the predetermined region or not based on the second optical data.
