Abstract: An electronic device is provided, including a main body, a battery detachably received in the main body, a stopper disposed in a predetermined position to restrict the battery in the main body, an antenna disposed on the stopper, and a cover connected with the stopper and movable relative to the stopper between a first position and a second position. When the cover is in the first position, the cover is engaged with the main body and restricts the stopper in the predetermined position. When the cover is moved from the first position along a first direction to the second position, the cover is disengaged from the main body, and the stopper is releasable from the predetermined position along a second direction.

Abstract: A fabric-based pressure sensor array includes: (1) a first layer including M elongated conductive strips coated thereon; (2) a second layer including N elongated conductive strips coated thereon, the M elongated conductive strips extending crosswise relative to the N elongated conductive strips to define M×N intersections; and (3) a unitary textile sheet extending between the first layer and the second layer so as to overlap the M×N intersections, the textile sheet having a variable resistivity in response to applied pressure so as to define M×N pressure sensors at locations corresponding to the M×N intersections.

Abstract: A multi-axis solid state accelerometer is made of electricity conductive material and is made by way of micro-machining. The main structure includes at least one proof mass connected to an anchor by several sensing beams and two boards are located on two sides of the main structure and fixed to the anchor. The sensing beams make the proof mass movable in parallel to or perpendicular to the boards. The surfaces of the proof mass include several grooves, which are parallel to the first axis and the second axis, and an area that has no grooves. Each board that face the grooves include two sets of electrodes and each of which includes several elongate electrodes located corresponding to the grooves. The two sets of elongate electrodes are located interposed each other. The board facing the area having no grooves has electrodes. The electrodes and the surfaces of the proof mass form detection capacitors for each axis.
