Abstract: A headphone includes a headgear and two earmuffs connected to opposite ends of the headgear, and each of the earmuffs includes an adjustment assembly. The adjustment assembly includes a base, two elastic members, two protrusions, and two sliding blocks. The base has two opposite accommodating parts and two guiding grooves. The elastic members are disposed in the accommodating parts, respectively, and the elastic members extend along a first axial direction. The protrusions are slidably connected to the guiding grooves, respectively, and protrude into the accommodating parts. The sliding blocks are disposed in the accommodating parts, respectively, and each of the sliding blocks is respectively connected between the corresponding protrusion and the corresponding elastic member.

Abstract: A method for automatically adjusting an autostereoscopic three-dimensional (3D) display device is provided. The method includes steps of: displaying an autostereoscopic 3D frame by the autostereoscopic 3D display device; capturing a left-eye frame and a right-eye frame of the autostereoscopic 3D frame by two image capturing devices located at a left-eye position and a right-eye position, respectively; selecting multiple sampling points from the left-eye and right-eye frames; and analyzing the number of the sampling points satisfying a predetermined condition to determine a display angle.

Abstract: A large multi-touch electronic whiteboard comprises a switch for switching to an external system from the internal system in response to the needs.

Abstract: A large multi-touch electronic whiteboard comprises: a swivel holder and a gravity sensor to adjust the screen rendering in response to the rotation of the screen; and a virtual key displayed on the screen for transmitting a tile to a mobile device via the Bluetooth device when the virtual key is clicked.

Abstract: A method of operating presentation through a multi-touch panel, comprises steps of providing a presenting module having a format transformation module, user interface generator and presenting/reading mode switching module to a system; activating the presenting module and display interface generated by the user interface generator on a multiple-touch panel of the system, wherein the interface generated by the user interface generator includes a shrinkage image area to display the non-activated file, an operation area to display file which is activated and a buffer zoon to allow a user drag file in the shrinkage image area to the operation area, thereby activating the dragged file.

Abstract: A multi-user operating system through a multi-touch panel comprises a processor; a storage medium coupled to the processor; a multiple touch panel coupled to the processor to sense multi-touch event by at least one user, followed by displaying instruction result corresponding to the multi-touch event; a display dividing module coupled to the processor to divide the multiple touch panel into at least two sub-display areas; multiple user operation module being stored in the storage medium to instruct the display dividing module to execute a multiple user mode or a single user mode, thereby allowing the multiple user manipulate virtual objects on the at least two sub-display areas, simultaneously.

Abstract: A method for operating computer objects and the computer program product thereof are disclosed, and they are utilized to a computer. The computer includes an operating interface which comprises defining a work region, function instruction list and a plurality of computer objects, and parts of the computer objects are chosen. The steps of the method comprises: an input device which is connected to a processing device in the computer for defining the position information of the input device, and a computer object which is chosen on the work region of the operating interface is clicked for operating the computer object; wherein a function instruction, which comprises actions of rotation, zoom in/zoom out, movement, of the computer object, is clicked for users to operate the computer object.

Abstract: A mechanical switch includes a housing. A substantially X-shaped conducting plate is received in the housing and provided with a first terminal pair and a second terminal pair mounted on the conducting plate. Two blades each are engaged with a corresponding one of the first and second terminal pairs. A pushbutton is pivotally mounted on top of the housing with two springs extending from the bottom of the housing to respectively engage with a corresponding one of the two blades to allow the two blades to change engagement with terminals in each of the first and second terminal pairs such that an electrical appliance is controlled.
