摘要:
The present invention provides systems and methods of an apparatus that comprises a layer of fingerprint imagers, an addressing circuit, a fingerprint controller, an electronic storage devices, a layer of touch panel and a display panel. The touch panel behind the layer of fingerprint imagers can sense touch position when touched. The specific fingerprint imagers can be activated according to the touch panel coordinates when touched by a user. After fingerprint is captured, the system evaluates quality of the captured fingerprint and admits fingerprint for recognition when its quality is above a threshold value. User of a computing system can be accepted or rejected based on the comparison between the captured fingerprint and an authorized fingerprint list.
摘要:
A generator with closed-magnetic-path coils includes a stator (8), a rotor (7), a casing (10) and a transmission shaft (6). A magnetic conductive bracket (9) and a coil winding (2) are fixed to the transmission shaft (6) to form the stator (8). One pole surface of a magnet (4) on the rotor (7) is corresponding to a profile surface of the coil winding (2). A prime mover drives the rotor (7) and the magnet (4) to rotate, and the magnet (4) cuts the coil winding (2) to induce a current.
摘要:
A stator for a generator with closed magnetic path comprises a coil support frame and a conductive wire unit arranged on the coil support frame. The conductive wire unit comprises a plurality of stacked basic conductive wire units. The basic conductive wire unit comprises a conductive wire layer and a magnetic-conducting sheet conformably stacked on and insulated from the conductive wire layer. The conductive wire layer comprises a plurality of conductive wires arranged in parallel and insulated from each other, or a conductive sheet with a plurality of elongated through gaps extending from a central region of the conductive sheet to a circumferential region of the conductive sheet, elongated portions between the elongated gaps function as conductive wires connected in parallel between the central region and the circumferential region. The conductive wire unit further comprises a shaped magnetic-conducting basic plate.
