Abstract: An embodiment of the invention provides a driving method for a display unit, wherein the display unit includes a first electrode, and a second electrode disposed opposite to the first electrode, wherein the first electrode is separated from the second electrode by a distance, and a first particle with a polarity is distributed between the first electrode and the second electrode. The driving method includes the steps of: casting a first voltage difference between the first electrode and the second electrode to make the first particle move toward the second electrode; stopping casting of the first voltage difference; and casting a second voltage difference between the first electrode and the second electrode to apply an opposite force to the first particle, wherein the polarity of the second voltage difference is different from that of the first voltage difference.

Abstract: An electric projector screen is revealed. A linkage member is sleeved in a winding tube in a fixed seat and a locator is fixed on the winding tube. An interlock pipe mounted with a connection part therein is arranged between the linkage member and the locator. The interlock pipe and the connection part are corresponding to each other for location. An output end of a motor in the interlock pipe is connected to the connection part while the other end of the motor is arranged with a fastening plate. The cover has limit holes corresponding to the locator so that the locator is pressed tightly by stoppers passing through the limit holes. Thus the screen fabric is located and limited during motor maintenance and replacement and damages caused by sudden opening of the screen fabric are prevented. The motor maintenance and replacement become easier and more convenient.

Abstract: A channel management method is provided for use in a channel management device. The channel management method includes the following steps. First, a scan request is received. Also, a number of television channels are scanned to generate a first set of channel list. Next, a number of network channels are scanned to generate a second set of channel list. Then, an integrated channel list is generated according to at least one set of channel lists which at least includes the first and the second set of channel lists. Afterwards, the content of a corresponding program is provided according to the integrated channel list and a selected channel thereof, when the selected channel is selected.

Abstract: A camera module comprises a main body, a cone disposed in the main body to accommodate a lens, a base joined to the cone, a frame movably disposed on the base, an image detection unit fixed to the frame and moving on the base via the frame, a first circuit board joined to the image detection unit and moving on the base via the image detection unit, a second circuit board disposed on the main body, and a flexible circuit board with one end connected to the first circuit board and the other end connected to the second circuit board. The flexible circuit board has a plurality of slits dividing the flexible circuit board into a plurality of strips. The slits are parallel and extend from the first circuit board to the second circuit board.

Abstract: A locator comprises a first clamping element, a second clamping element opposite to the first clamping element, a guide bar extending through the first clamping element and the second clamping element, and a transmitting element rotatably disposed between the first clamping element and the second clamping element and abutting the first and second clamping elements. When the transmitting element rotates, the first clamping element and the second clamping element move along the guide bar to approach or move away each other, thereby clamping or releasing an object.

Abstract: A camera module comprises a base, a lens joined to the base, a frame movably disposed on the base, an image detecting unit fixed to the frame and moving on the base via the frame, and a solenoid having a post moving between a first position and a second position. When the image detecting unit moves on the base via the frame, the post is in the first position and has no contact with the image detecting unit. When the image detecting unit moves on the base not via the frame, the post is in the second position and abuts the image detecting unit to position the image detecting unit.

Abstract: A multi-page electronic program guide displays the program information for only one selected channel on each screen. The names of various channels are labeled in channel cells at the left side of the screen when the program information of the selected channel is displayed on the major screen. Thereby, the user can select other channels from the channel cells. Once a specific channel is selected, the program displayed in various time zones are completely displayed on one screen.

Abstract: A papermaker includes a mesh having a plurality of protrusions used to screen water and fiber that has not been broken down from a pulp is also used to web the pulp into a pulp web, such that a plurality of holes is formed to extend through the pulp web. After squeezing and drying steps, a paper with a plurality of voids is formed. The voids are formed without subsequent cutting process, such that the amount of pulp used for making the paper is reduced, and the cost and labor are reduced. Alternatively, when a pulp is webbed by a conventional mesh into a pulp web, a mold having a plurality of protrusions may be used to press the pulp web, so as to form the voids in the pulp web. Thereby, voids are formed simultaneously with the paper.
