Abstract: A wireless charging holder and an assembly of an electronic device and the wireless charging holder are provided. The wireless charging holder includes a body, a fixing element, a power line, a first coil, and a first magnetic element. The body is used to hold the electronic device. The fixing element has a first end connecting with the body and a second end fixed on a vehicle. The power line has a third end connecting with the body and a fourth end to plug into a socket. The first coil on the body is electronically connected with the power line. The first magnetic element disposed in the body is adjacent to the first coil. The electronic device having a second coil is fixed by the first magnetic element on the body, and the first coil overlaps the second coil to induce current for charging the electronic device.

Abstract: A computer system capable of detecting an identification (ID) of a peripheral device connected thereto includes a connection circuit having a peripheral interface connectable to the peripheral device and a data transmission interface for data transmission between the peripheral device and a CPU of the computer system, a detect circuit connected to the connection circuit and a DC voltage source of the computer system, and a convert unit. The detect circuit has an output terminal set and a plurality of resistors having resistances for producing a specific DC potential divided by the DC voltage source at the output terminal set. The convert unit is coupled to the output terminal set and the CPU for converting the specific DC potential at the output terminal set into a digital signal corresponding to the ID of the peripheral device for output to the CPU.

Abstract: A flashlight having a mechanism for preventing electrical contact members thereof from rusting comprises a battery frame including a plurality of slanted flexible bifurcation members for receiving one or more batteries, each bifurcation member having a recess proximate the electrode. In an unused position, batteries are disengaged from each other and from a bulb and a conductor coupled to bulb. While in use, by pushing a switch to hold bifurcation members upright in a secured position so that batteries, bulb, and conductor are electrically coupled together with electrodes and a protuberance of conductor inserted through recesses, thereby forming a circuit from bulb to conductor via batteries.
