Shoe light device capable of flashing in different modes and driving method thereof
The invention relates to the technical field of shoe lights; in particular, to a shoe light device capable of flashing in different modes and a driving method thereof. A motion sensor, an integrated chip and a light-emitting device are integrated on a shoe, and the motion sensor and the light-emitting device are electrically connected to the integrated chip. The integrated chip is configured to control the light-emitting device to emit light in a preset constant-sequence output mode when the duration of reception of pulse signals generated by the motion sensor reaches a preset threshold, so that trigger control over the light-emitting device is realized. The shoe light device capable of flashing in different modes has the advantages of high integrity of elements, simple structure, simple production process, and various integrated cyclic output modes for flashing of the light-emitting device.
Electrical contact geometry for switchgear
Systems, devices, and methods disclosed herein can generally include electrical contacts for high voltage, high current, and/or fast acting electromechanical switches and methods for manufacturing the same. The electrical contacts can be optimized for high voltage blocking capabilities with minimal gap spacing in the open state and low electrical resistance when in contact in the closed state. Electrical contacts can have a geometry to produce a low peak electric field between the contacts when in the open state, have a high contact surface area when in the closed state, and a low mass. The geometry of the contacts can be based on geometries traditionally utilized for uniform field electrodes.
