Abstract: A modular plug includes a main body and a fixing block. The main body includes an upper housing, a lower housing, and blades. The upper housing includes a first top surface defining slits for respectively retaining one contact and a first bottom surface defining a first cavity and indents extending from one sidewall of the first cavity. The first bottom surface includes wires being connected with one contact. The lower housing includes a second top surface, abutting against the first bottom surface of the upper housing, and a second bottom surface. The second top surface defines a second cavity and slots extending from one sidewall of the second cavity. The second bottom surface forms an elastic tab extending therefrom. The blades are respectively received in one indent. The fixing block is fitted in to the first cavity and the second cavity and includes fixing portions fixing cores of a cable.

Abstract: A system for locking an electronic device is provided. The system includes an electronic device, and electronic keys electrically connected to the electronic device. The electronic key includes a plurality of resistors which are connected in series, the resistance value of the electronic key is changeable by coupling different resistors of the electronic key. The electronic device comprises of a processing unit and a function key. When the function key produces locking command in response to user operation, the processing unit obtains the resistance value of the electronic key and produce encryption key according to the obtained resistance value to unlock the electronic device. When the function key produces unlocking command, the processing unit decodes the encryption key and unlocks the electronic device when determining the obtained value matches the decoded encryption key.

Abstract: A lighting device comprising: a shell, a plurality of luminophors, a first slideway and a second slideway. The plurality of luminophors is set in an external surface of the shell. The first slideway and the second slideway each of which comprise an up peristome and a down peristome respectively. A plurality of trigger switches is set in the first slideway. Each of which is configured for connecting/disconnecting a first circuit, so as to turn on/off the one or more luminophors. A ball is located movable along the slideways. A launching device is set in a bottom of the second slideway and is configured for driving the ball to move. A controlling unit is configured for connecting/disconnecting a second circuit, so as to connect/disconnect a power supply, which supplies power for the lighting device via the first circuit.

Abstract: An LED light lamp includes a lamp body, an adjusting rod, a number of light panels, and at least one rheostat. The lamp body defines a chamber therein. The adjusting rod includes a sliding bar, and an adjustable panel extending outwards from and surrounding an end of the sliding bar. The sliding bar is slidably received in the chamber of the lamp body. The adjustable panel includes an annular periphery. Each light panel includes a number of LED chips distributed on the light panel, and is pivotally mounted on the lamp body and against the annular periphery of the adjustable panel. A rheostat is electrically coupled into a power supply circuit of the LED chips. The resistance of the rheostat is adjusted to control the current flowing through the LED chips by the sliding bar when the sliding bar slides in the lamp body.

Abstract: A wireless computer mouse includes a first operating portion, a second operating portion, a circuit board, and a switch. A pair of LEDs is mounted on the circuit board. One of the LEDs corresponds to the first operating portion, and another LED corresponds to the second operating portion. An optic member is mounted on the circuit board. The optic member includes two opposite reflecting portions. Each of the reflecting portions corresponds to one LED, and each of the reflecting portions is configured to reflect the light of the corresponding LED to highlight a surface underneath the mouse. The switch is configured for selectively enabling the first operating portion and the second operating portion. When the first operating portion is enabled, the LED corresponding to the first operating portion lights. When the second operating portion is enabled, the LED corresponding to the second operating portion lights.

Abstract: A computer mouse includes a left key assembly, a right key assembly, a signal processing unit, and a casing. The casing includes a top casing and a bottom casing. The bottom casing includes a bottom convex surface, the contour of the bottom convex surface is an ellipse, the bottom casing defines two first openings in the bottom convex surface, and the two key assemblies are positioned in the corresponding first openings. Each of the left key assembly and the right key assembly includes a hollow receiving column, a movable shaft, an elastic member and a pressure sensor. The movable shaft is received in the receiving columns. The movable shaft and the pressure sensor are spaced from each other via the elastic element. The pressure sensor will generate a corresponding pulse when pressed by the movable shaft. The signal processing unit receives the pulse, and sends a controlling signal.

Abstract: A presentation assembly for displaying data from a data source includes a liquid crystal display, a projection lens, and a projecting unit. The liquid crystal display includes a panel configured for displaying a graphical user interface, and a frame fitted to the liquid crystal display. The projection lens is mounted to the rear surface of the frame, and extends out of the frame. The projecting unit is installed within the liquid crystal display and includes a storage sub-unit and a signal processing sub-unit. The storage sub-unit is configured for storing a data stream needed to be projected. The signal processing sub-unit is configured for transforming the data stream needed to be projected into a projectable signal input to be projected by the projection lens.

Abstract: An encryption/decryption system includes a displaying unit, an operating unit, a pressure sensing unit and an indicating unit. The displaying unit is configured for displaying files. The operating unit is configured for selecting a desired file to be encrypted or decrypted. The pressure sensing unit is integrated with the operation of sensing a pressure applied on the operating unit and producing a signal corresponding to the sensed pressure. The indicating unit is integrated on the operating unit. The indicating unit is configured for receiving the signal outputted from the pressure sensing unit, emitting a sensible signal according to the signal associated with a sensed pressure, and recording a signal associated to the pressure and the duration of the pressure as a mixed password for use in the operation of encryption or decryption of the selected file.
