Abstract: A bra fastener, comprising a first part (10) and a second part (20). The first part comprises a first connecting band (11) and a plurality of first fastening pieces (12) which are disposed at intervals at the interior of the first connecting band (11) along the length direction of the first connecting band (11), and one surface of the first connecting band (11) is provided with a through hole (111) at a position corresponding to each first fastening piece (12). The second part (20) comprises a second connecting band (21) and a second fastening piece (22) disposed at the interior of the second connecting band (21). The second fastening piece (22) partially extends from one surface of the second connecting band (21) and may pass through one of the through holes (111) on the first connecting band (11) so as to be buckled to a first fastening piece (12) corresponding to the through hole (111).

Abstract: An on-demand data management system. The system comprises a file management module and a demand analysis module. The file management module receives files. Each file has attributes. The file management module segments the files according the attributes. The demand analysis module receives a data demand and selects data from the segmented files according to the data demand.

Abstract: The present invention is an apparatus for driving white LEDs. The apparatus includes a switchable current sink, a DC-DC converter and a reference circuit. The DC-DC converter provides a driving voltage to a plurality of LEDs. The switchable current sink regulates currents through the plurality of LEDs, and the switchable current sink further provides a first reference voltage and outputs a plurality of voltage drops. The reference circuit receives the first reference voltage and the plurality of voltage drops to provide a second reference voltage to the DC-DC converter. The DC-DC converter adjusts the driving voltage provided to the plurality of LEDs according to the second reference voltage. In this way, the driving voltage is regulated to a minimum possible value and consequently the voltage drops across the switchable current sink is minimized. Hence, the LED driving system maintains higher efficiency.

The switch is coupled between a power supply and the plurality of LEDs. The PWM generator is coupled to the power supply and the switch, and is capable of generating a PWM signal and controlling the brightness of the plurality of LEDs.

Abstract: A method for booting a computer to play a compact disc without loading an operation system is provided. The computer has a first booting button and a second booting button. The first booting button is for booting the computer completely and loading the operation system normally. And the second booting button is for booting the computer incompletely to drive a part of devices of the computer thereof for playing a compact disc without loading the operating system. The method includes the steps of ascertaining whether a booting action is triggered by the second booting button, initializing the part of devices of the computer when the booting action is triggered by the second booting button, activating an optical disc drive to read the compact disc by pressing predetermined keys located on a general keyboard, and to play through a speaker.

Abstract: A card connector is compatible with different types of memory cards. The card connector has an insulative frame and a plurality of conductive terminals received in the insulative frame. The insulative frame has a plug portion defining a plurality of slots for receiving different memory cards. The card connector has an anti-misplug mechanism mounted on the insulative frame. The anti-misplug mechanism includes a pressing pate and a spring strip. The pressing plate has an end pivotably received in the insulative frame and a stop portion stopping one of the slots in assembly. The spring strip is mounted below the pressing plate for providing returning force. When a card is received in one of slots in the insulative frame, the stop portion stops other slots of the insulative frame, thereby avoiding insertion of other memory cards into the card connector by mistake.
