Abstract:
A lead frame of a through-hole light emitting diode (LED) is used to carry an LED chip, and a lens is used to package the chip and a portion of the lead frame. The lead frame includes at least two leads. One lead is used to carry the chip and each of the leads is extended outward from the lens and has a positioning bump. The positioning bumps partially protrude from the lens, such that when the lead frame is disposed on a circuit board, the lead frame is positioned through the positioning bumps and aligns the lens to guide an optical axis of the through-hole LED, thereby achieving the purposes of convenient assembly, thinness, and a reduced thermal-conducting distance.
Abstract:
A removable hard disk module is described. The removable hard disk module has a module sidewall, a first slide rail, and a second slide rail. The first slide rail and the second slide rail are fixed on the module sidewall and the second slide rail is disposed above the first slide rail. The first slide rail is made of a linear material such as a piano wire or the like. The second slide rail is directly formed on the module sidewall or made of the linear material. The removable hard disk module further includes a handle with a withdrawal post to push a support stud on a module fixing device for withdrawing the removable hard disk module from the module fixing device when the handle is opened.

Abstract:
A multi-frequency antenna includes a microwave substrate, a first antenna unit, a second antenna unit, a third antenna unit and a grounding unit. The first antenna unit, the second antenna unit, and the third antenna unit are disposed on the microwave substrate surface. The grounding unit is disposed at an edge on the surface of the microwave substrate. The grounding unit is in connection with the second antenna unit. The second antenna unit and the third antenna unit are bent to form perpendicular structures to the microwave substrate. The compact arrangement reduces the physical footprint of the antenna module to enable fitment in a wide range of products having tight special constraint.
Abstract:
A mouse with an adjustable resolution function executes the cursor control function normally. The mouse includes an adjustment unit, a processor, and a sensor unit. The adjustment unit optionally generates an adjusting signal and transmits the adjusting signal to the processor. The processor receives the adjusting signal, generates a control signal correspondingly and transmits the control signal to the sensor unit. According to the control signal and the moving path of the mouse, the sensor unit correspondingly generates a displacement signal to the processor and enables the mouse to execute the cursor moving function in accordance with the displacement signal.
Abstract:
A wireless mouse for inputting commands to a host computer includes a casing, a control circuit, a wireless receiver, an electronic switch circuit and a resilient member. The control circuit includes a wireless module to transmit a wireless signal to the wireless receiver. The wireless receiver can be either received in the port of the casing or attached to a connector of the host computer.
