    IPC: G06F3/042

    CPC classification number: G06F3/042

    Abstract: There is provided an optical touch system including a touch surface, a plurality of image sensors and a plurality or compensation light sources, wherein each of the image sensors is adjacent to one of the compensation light sources. When one of the image sensors is capturing an image frame, the compensation light source not adjacent to and within a field of view of the image sensor which is capturing the image frame irradiates so as to compensate a brightness distribution of the image frame.

    IPC: G08B17/107

    CPC classification number: G08B17/107

    Abstract: There is provided a smoke detector including a light source, a reflective surface, a light sensor and a processor. The light sensor receives reflected light when the light source emits light toward the reflective surface, and generates a reference detection signal when there is no smoke. The processor receives the detection signal from the light sensor, and automatically selects a set of predetermined condition thresholds according to a profile of the detection signal to be compared with the detection signal thereby determining whether to generate an alarm according to the comparison result.
