Abstract: A mobile music store assembly includes a housing base; a first housing member that is selectively movable relative to the housing base between a first position wherein the mobile music store assembly is in a closed configuration, and a second position wherein the mobile music store assembly is in an open configuration; and a second housing member that is selectively movable relative to the first housing member and the housing base between a first position wherein the mobile music store assembly is in the closed configuration, and a second position wherein the mobile music store assembly is in the open configuration. The mobile music store assembly can further include a music player that is positioned substantially within the housing assembly. The music player is only accessible when the mobile music store assembly is in the open configuration.

Abstract: A digital audio signal reproducing device includes a system processor, a first rotation disk, a second rotation disk, a first sensor, a second sensor, and a lighting assembly. The first sensor detects rotation speed and direction of the first rotation disk to output a first control signal. The second sensor detects the second rotation disk being pressed to output a second control signal. When the first control signal and the second control signal are outputted to the system processor simultaneously, the lighting assembly is controlled by the system processor to perform a first blinking mode, and when only the first control signal is outputted to the system processor, the lighting assembly is controlled by the system processor to perform a second blinking mode.

Abstract: One embodiment of the invention includes a method for preventing a plurality of electronic devices from being pulled out of an equipment rack simultaneously. The method includes determining with an electronic sensor module whether an electronic device of a plurality of electronic devices coupled to the equipment rack is being slid out of the equipment rack. Provided the electronic device is being slid out of the equipment rack, an electronic locking module prevents any remaining electronic device of the plurality of electronic devices from being slid out of the equipment rack. A determination is made as to whether the electronic device has been slid back into the equipment rack. Provided the electronic device has been slid back into the equipment rack, the prevention is deactivated.

Abstract: A disk player includes: a base unit, to which a display unit is rotatably connected, having an upper housing and a lower housing, a board installed between the upper housing and the lower housing, a display LCD installed on an upper surface of the board for displaying operational state through the upper housing, and a board connection unit installed on and connected to the board, and connected to one side of the display LCD, for transferring signal to the display LCD.

Abstract: A multitasking information processing method comprises the steps of (a) providing a plurality of turntables each for detachably storing an optical disc thereon; (b) affording a plurality of optical units each comprising a driving means and an optical read head; (c) simultaneously controlling the driving means so as to move the optical read heads in radial directions of the optical disc to a plurality of predetermined disc positions for simultaneously retrieving information stored thereon; (d) multitaskingly or simultaneously processing a plurality of information sets retrieved; and (e) rendering data transmitting means capable of multitaskingly transmitting the processed information sets processed.
