Abstract: An adjustment module is capable of adjusting a position of a lens of a projector. The adjustment module includes a base, a first tray, a second tray, at least one guide roller, and at least one boundary constrainer. The first tray is slidably disposed on the base along a first axis. The second tray is slidably disposed on the first tray along a second axis substantially perpendicular to the first axis. The lens is fixed on the second tray. The guide roller is rotatably disposed on the second tray. The boundary constrainer is disposed on the base. The guide roller is capable of confining the lens within an image area of the lens by rotatably contacting the boundary constrainer.

Abstract: A data processing system including an electronic device and a multi-function peripheral is provided. The electronic device has a device code and stores a user-setting file. The multi-function peripheral connects with the electronic device via a transmission interface. The multi-function peripheral includes a memory unit and a processing unit. The memory unit stores identification data. The processing unit requests the electronic device to transmit the user-setting file to the multi-function peripheral through the transmission interface according to the identification data, and executes the user-setting file.

Abstract: A computer and a method for processing keyboard input thereof is disclosed. The method includes the steps of receiving an interrupt request; reading a scan code stored in a scan code buffer; determining whether the scan code is a predetermined scan code representing an Fn key; reading an event code stored in an event code buffer if the scan code is the predetermined scan code; and executing a corresponding service program or function according to the event code.

Abstract: A buckle structure includes a housing including a top plate and two side plates, a sliding wedge and a pivotal piece. Each side plate has a guiding slot. The sliding wedge is positioned below the housing and has projection portions projecting from its two sides. The projection portions are fit into corresponding guiding slots of the housing, and stoppers are positioned on top surface of the sliding wedge. The waist belt is fastened by the stoppers positioned on top surface of the sliding wedge so that the waist belt will not be loosed. Connection portions are extending from the top plate, and each connection portion has a through hole at its midpoint. Pivotal pins are extending from the pivotal piece and correspond to the through holes of the two connection portions. The pivotal piece is formed with the two pivotal pins so structure is simplified and cost is lowered.

Abstract: The present invention provides a fan to generate airflow passing around a lamp reflector. A wake region is formed near a leeward surface of the lamp reflector, and a light cut is installed in the wake region. The light cut has a fixing end and is fixed on a side end surface of a lamp holder of the lamp by means of fastening bolts, the other end keeps a selected distance away from the lamp reflector and has a suitable distance along contours of the lamp reflector toward a rear end of the lamp reflector so as to prevent the light with high illumination going through the lamp reflector to the exhausting outlet for avoiding light leakage; hence, the exhausting outlet shall not be added inclined louvers and the windage is lowered down comparatively.

Abstract: The present invention provide a fan to generate airflow to pass around a lamp reflector with an organized figure of column and cone. A wake region is formed on a leeward surface of the lamp reflector, and a light cut is installed on the wake region. The light cut has a fixing end and is fixed on a side end surface of a lamp holder of the lamp by means of fastening bolts, the other end keeps a selected distance away from the lamp reflector and has a suitable distance along contours of the lamp reflector toward a rear end of the lamp reflector so as to that to prevent the light with high illumination going through the lamp reflector to the exhausting outlet for avoiding light leakage; hence, the exhausting outlet shall not be added inclined louvers and the windage is lowered down comparatively. Therefore, the heat-dissipating efficiency is raised to effectively reduce the heat loading of the projector, promote products life and decrease noise.

Abstract: This disclosure relates a cylinder lock with anti-picking device. A shaft is provided to extend into the keyway of the lock to prevent the entry of any foreign object. Only when a special tool is used to retract the shaft can a key be inserted into the keyhole, thereby eliminating the risk of picking by unauthorized persons.
