Abstract: A testing stylus used for testing a keyboard, includes a sleeve, a resisting member and an elastic member, the resisting member be conductive and have an engageable end and an opposite resisting end, the resisting end is used to resist against the keyboard. The resisting member and the elastic member are assembled in the sleeve, the elastic member resists against the engageable end, to allow the resisting end to be exposed to the outside from the sleeve, the resisting end is withdrawn into the sleeve by pressing the sleeve.

Abstract: A testing module is provided including a driving assembly, a positioning assembly and a testing head mechanism. The positioning assembly positions the driving assembly and the testing head mechanism therein. The positioning assembly includes a positioning member. The positioning member includes a base seat. The base seat defines a receiving cavity. The testing head mechanism includes a cushioning mechanism accommodated in the receiving cavity and driven by the driving assembly to move relative to the positioning assembly.

Abstract: A light emitting diode (LED) illuminating apparatus (100) includes a controller (20) and an illuminating member (10). The controller is configured for setting a luminance of the LED illuminating apparatus and creating a luminance level value according to the luminance. The illuminating member includes a processor (13), a regulating circuit (15) and an LED lamp (17), the processor is connected to the controller to store the value, the regulating circuit is connected to the processor to receive signals transformed from the value and form output currents sent to the LED lamp according to the signals, thus the LED lamp emits light has the predetermined luminance.

Abstract: A connector apparatus (100) having an alarm function is described. A connector (10) can be connected to an electronic device and generate a pulse signal. A number of the pulse signal is a time of plugging and unplugging of the connector. A micro control unit (30) is electronically connected to the connector and receives the pulse signal. The micro control unit counts the number of the pulse signal, and a number of plugging and unplugging of the connector is predetermined thereby. A display module (50) is electronically connected to the micro control unit and used for displaying the number of the pulse signal. An alarm unit (70) is electronically connected to the micro control unit, when the number of the pulse signal reaches the predetermined number, the micro control unit sends a caution signal to the alarm unit, and the alarm unit generates a warning signal.
