Abstract: A dual sensing method of an object and a computing apparatus for object sensing are provided. In the method, a first clustering is performed on radar information including a plurality of sensing points and is for determining a first part of the sensing points to be an object. A second clustering is performed on a result of the first clustering and is for determining that the sensing points determined to be the object in the result of the first clustering are located in a region of a first density. A result of the second clustering is taken as a region of interest. According to the region of interest, object detection and/or object tracking is performed on combined information formed by combining the radar information and an image, whose respective detection region and photographing region are overlapped.

Abstract: A resin composition, an anti-etching layer and an etching method are provided. The resin composition includes a resin (A), a crosslinking agent (B), a surfactant (C), and a solvent (D). The resin (A) includes a hydroxyl type polystyrene resin (A-1), a hydroxyl type phenolic resin (A-2), a polyhydroxy phenol resin (A-3), or a combination thereof. The crosslinking agent (B) includes a structure of novolac epoxy resin type (B-1), polymethyl methacrylate type (B-2), maleimide type (B-3) or hyperbranched oligomer (B-4).

Abstract: An electronic device includes a processor, a timer and a memory device. The memory device stores a value for power-on hours. During the process of booting the electronic device, the processor triggers the timer to start counting down. When the timer expires, the processor updates the value of power-on hours.

Abstract: An audio system includes a reference voltage generation circuit to generate a digital encoding signal and generate an analog reference voltage according to the digital encoding signal, wherein, during a booting procedure and/or a shutdown procedure, the analog reference voltage is smoothly increased and/or decreased at a smooth rate related to a bit number of the digital encoding signal; a first analog operational amplifier for receiving the analog reference voltage to generate a common voltage, which is smoothly increased and/or decreased during the booting procedure and/or the shutdown procedure; and a differential analog operational amplifier pair, coupled to the first analog operational amplifier, for receiving a differential audio input signal pair and outputting a differential output voltage pair to drive a load, wherein, during the booting procedure and/or the shutdown procedure, the differential audio output signal pair is smoothly increased and/or decreased.

Abstract: An electronic device includes a processor, a timer and a memory device. The memory device stores a value for power-on hour(s). During the process of booting the electronic device, the processor triggers the timer to start counting down. When the timer expires, the processor updates the value of power-on hour(s).
