    Abstract: A force sensing method, applied to a force sensing system comprising a plurality of force sensors and a touch sensing surface, comprising: (a) determining a first location of a first object on the touch sensing surface; (b) defining a first force sensing region according to the first location; and (c) computing a first system sensing force which the first object causes to the touch sensing surface according to the first location, and according to at least one sensor sensing force of a first part of the force sensors corresponding to the first force sensing region. The present invention also discloses a force sensing system which uses the above-mentioned force sensing method, and an efficient force sensor calibration method. Noises can be reduced and power consumption can be decreased, since only sensor sensing forces of force sensors near the object are used for computing the system sensing force.

    Abstract: An earphone device includes a housing subassembly, an inner casing subassembly, an audio processor, and a force sensor patch. The inner casing subassembly is disposed in the housing subassembly and integrated with a printed circuit board having specific electrode (s). The audio processor is disposed on the printed circuit board. The force sensor patch is pasted onto specific electrode (s) of the printed circuit board to be coupled to the audio processor through specific electrode(s). The force sensor patch is disposed between a part of the housing subassembly and a part of the inner casing subassembly and arranged to detect a user's pressure applied onto the part of the housing subassembly.

    Abstract: A smoke detection device includes a housing, a smoke collector, an optical detector and a cover plate. The housing has a piercing hole. The smoker collector has a smoke hole, and position of the smoke hole is close to position of the piercing hole. The optical detector is disposed inside the smoke collector and adapted to detect gaseous concentration inside the smoke collector. The cover plate is disposed between the housing and the smoke collector, and used to set a channel from the piercing hole to the smoke hole, so that gaseous matter flows from outside the smoke detection device into the smoke collector through the piercing hole and the smoke hole.
