Abstract:
A wireless mouse apparatus includes a mouse wheel module and an encoder signal processing and induced electromotive force processing circuit. The mouse wheel module includes a mouse wheel, two stator plates, a plurality of coils and a rotation shaft. The mouse wheel includes a multipolar magnetic body. The coils are arranged on the stator plates. The rotation shaft is connected to the mouse wheel and the stator plates. The encoder signal processing and induced electromotive force processing circuit is used for decoding two signals of phase lead or lag produced representative of rotating of the mouse wheel in the two directions of scroll down or scroll up. The encoder signal processing and induced electromotive force processing circuit converts the alternating current induced electromotive forces into direct current induced electromotive forces and then stores in an energy storing apparatus.
Abstract:
An early detection electronic device of diabetic foot for lesion in the blood circulation detects foot temperatures and includes a base, a first temperature detector, a second temperature detector, and a microprocessor. The base includes a platform part, a first arranging part, and a second arranging part. The first arranging part is connected to the platform part and the second arranging part. The first temperature detector is arranged on the first arranging part and detects foot temperature along a first axis. The second temperature detector is arranged on the second arranging part and detects foot temperature along a second axis. There is an included angle between the first axis and the second axis. The microprocessor receives the temperatures detected by the first temperature detector and the second temperature detector, and generates a warning signal when the first temperature is lower than the second temperature.
Abstract:
A self-powered wireless mouse apparatus includes a mouse wheel module and a back-end processing module. The mouse wheel module includes a mouse wheel, a stator plate, a plurality of coils and a rotation shaft. The mouse wheel includes a multipolar magnetic body. The coils are arranged on the stator plates. The rotation shaft is connected to the mouse wheel and the stator plate. The back-end processing module includes an alternating current to direct current conversion circuit and an energy storing apparatus. The multipolar magnetic body is driven so that the coils generate induced alternating current voltages when the mouse wheel is rotated. The alternating current to direct current conversion circuit converts the induced alternating current voltages of the coils into direct current voltages and then stores the direct current voltages in the energy storing apparatus to supply power to the self-powered wireless mouse apparatus.
