Abstract: A probe for high frequency signal transmission includes a metal pin, and a metal line spacedly arranged on and electrically insulated from the metal pin and electrically connected to grounding potential so as to maintain the characteristic impedance of the probe upon transmitting high frequency signal. The maximum diameter of the probe is substantially equal to or smaller than two times of the diameter of the metal pin. Under this circumstance, a big amount of probes can be installed in a probe card for probing a big amount of electronic devices, so that a wafer-level electronic test can be achieved efficiently and rapidly.

Abstract: A light-emitting diode (LED) is provided, wherein the LED comprises an epitaxial structure, a bonding layer and a composite substrate. The composite substrate comprises a patterned substrate having a pattern and a conductive material layer disposed around the patterned substrate. The bonding layer is formed on the composite substrate. The epitaxial structure is formed on the bonding layer.
Abstract: A portable storage device with network function includes a network file management system, via which an electronic apparatus coupled to the portable storage device manages the access of files between a memory unit of the portable storage device and a remote network host. Therefore, the portable storage device with network function is more convenient for use.
Abstract: A weapon mount tactical light trigger includes a mount for Picatinny rail to clamp to a shotgun or rifle, a light mount to clamp a tactical light, and a principle mount to joint both mounts with a trigger base fixed at the back. Components of the trigger base include a trigger to switch on/off the tactical light, a circular shaft to allocate the trigger on the trigger base and a fixing bolt to keep the trigger and switch of the light to stay connected under normal conditions. When a user presses the trigger with a finger, the trigger pivots on the circular shaft and exerts pressure to the switch of the tactical light. The structure design of the trigger base is according to the principle of leverage; via pressing the trigger, it exerts pressure to the switch to turn on/off the light; as the mechanism design of this creation avoids possible shortfall of wire conduction and enhance the performance stability of the tactical light.
Abstract: A trigger activating tactical light grip includes a Picatinny rail mount to assemble the grip to the firearm, a tactical light mount to mount the tactical light and a grip to provide a place for holding the gun. In the grip, there is a trigger to initiate movement for a connecting rod, and the connecting rod is to deliver the movement of the trigger, a tunnel for the connecting rod to slide along, a circular shaft to assemble the trigger, and a fixing pin to keep the connecting rod to be contacted with the tactical light switch. When a user provides pressure with a finger on the trigger, it pivots on the circular shaft and leads the connecting rod to slide along the tunnel. As a result, the connecting rod exerts pressure to the switch of the tactical light and then the aim of activating the tactical light is accomplished.
