A circuit is used for driving a plurality of lamps, such as Cold Cathode Fluorescent Lamps (CCFLs). The lamps are paired to form a plurality of pairs of lamps. Each of the plurality of pairs of lamps has two lamps which are coupled to each other in series. The plurality of pairs of lamps are coupled in parallel. The circuit comprises a switch circuit, a transformer, and a plurality of balance chokes. The switch circuit is used for converting a DC electric power into a first AC electric power. The transformer has a primary winding and a secondary winding. The primary winding of the transformer is coupled to the switch circuit for receiving said first AC electric power and energizing the secondary winding to generate a second AC electric power from the secondary winding to energize the plurality of lamps. Each of the balance chokes includes a first winding and a second winding. The first winding and the second winding of each of the balance chokes are coupled to two of the plurality of pairs of lamps in series, respectively, so as to balance currents flowing through those two pairs of lamps.

A handheld electronic device with a function for magnifying/reducing an initial image displayed on the hand held device, and displaying at least one magnified/reduced image without shifting a focal point identified by the initial image and the applications of the same are provided. The handheld electronic device comprises a display unit, a position selector and an image magnification/reduction unit. The display unit is used for displaying the initial image and the at least one magnified/reduced image. The position selector is used to designate a datum mark associated with the focal point of the initial image. The image magnification/reduction unit, used to conduct at least one image magnification/reduction process to continually magnify/reduce the initial image in accordance with the datum mark, whereby each of the at least one magnified/reduced image is then displayed on the display unit immediately after each of the at least one magnification/reduction process.

The display control apparatus of the present invention includes a motion sensor, a processor and a display controller. The motion sensor is used to sense the motion of an electronic device and sends out a motion parameter to a processor. Each motion parameter is related to a special motion direction and motion velocity. When the processor receives a motion parameter, a corresponding display instruction is triggered. This display instruction is sent to the display controller to move the page based on the motion direction and motion velocity.

A multi-configuration portable electronic device including a first body, a second body, a dual-axis hinge and at least a guiding module is provided. The dual-axis hinge has a first axis pivotally coupled to the first body and a second axis pivotally coupled to the second body. The guiding module prevents the first axis and the second axis from acting simultaneously. The guiding module includes a track disposed in the first body and a slide connected with the second body. The slide has an interaction force with the track so that the slide can move from the second body to couple with the track.

Search methods. A string is first received. The string is divided to generate at least one string fragment set, comprising of at least a first and a second fragments. A record conforming to the string fragment set is searched for and retrieved. A first data block of the record may include or begin with the first fragment, and a second block may include or begin with the second fragment. The first block may include or begin with the second fragment, and the second block may include or begin with the first fragment.

Dialing methods for use in a device having a keypad. The keypad comprises a plurality of dual-purpose keys and non-numerical-purpose keys. The dual-purpose key has different input definitions in a letter mode and a number mode, and the non-numerical-purpose key does not have a numerical input definition. First, at least one keystrokes are received, and an input sequence corresponding to the keystrokes is generated. If any one of the keystrokes corresponds to one of the non-numerical-purpose keys, at least one address record conforming to a letter input definition of the input sequence in the letter mode is retrieved from an address book for dialing accordingly.

The present invention relates to a data management method between a mass storage device and a data capture/storage device. When the data capture/storage device is connected to the mass storage device, a connection signal is generated. The connection signal initiates the transfer of data files from the data capture/storage device to the mass storage device. Then, a first marker is added to the data files in the data capture/storage device, so the transferred data files can be differentiated from the not-yet transferred.

A keyboard with multifunction keys on a panel of a handheld electronic device is provided. The multifunction keys are set in a transverse, tilted or vertical direction and used for typewriting. Each multifunction key has a linear configuration and comprises three symbols such that depressing a central part of the key inputs a first symbol and depressing one end of the key inputs a second symbol while depressing the other end of the key inputs a third symbol. Therefore, the number of keys as well as the total area occupied by the keys on the handheld electronic device can be reduced.

Oriented longitudinal magnetic recording media on direct texture glass or glass-ceramic substrates with a film structure of one or more Ni-containing layer, a Cr-containing underlayer, a Co-containing magnetic layer and carbon overcoat exhibits are capable of achieving Mrt OR of >1.5, preferably >1.85. Such highly oriented glass media shows a significant SNR (>2 dB) and parametric improvement over the counterpart isotropic media with the same film structure on non-textured glass or glass-ceramic substrates.
