Abstract: The present invention relates to a wireless communication system, comprising: a wireless communication device; and an external mechanism; wherein the wireless communication device comprises: a wireless media access controller; an antenna selector, being a switch of a switchable antenna; an antenna connector, connecting the external mechanism; and a built-in antenna; wherein the external mechanism comprises: a support mechanism; and an external antenna supported by the support mechanism.

Abstract: A combination lock includes an outer case with an inner case received therein and the outer case has a chamber which communicates with a passage in which a latch is received. A spring is mounted to the latch and provides a force to move the latch in a direction away from the chamber. A front unit having two disks is located in the first chamber and a rear unit having two disks is located in the second chamber. The two disks of the front unit drive each other and the two disks of the rear unit drive each other. A first dial plate drives one of the disks of the front unit and a second dial plate drives one of the disks of the rear unit. When the notches are in alignment with each other, the end piece of the latch can pass through the notches and the lock is unlocked.

Abstract: A multistage lock apparatus has a base, a disk holder, two selecting devices, two disk sets and at least one interfering element. The base has a mounting panel and a central tube. The disk holder is connected to the base and has a mounting beam, two extending beams, a middle beam, a connecting beam and two mounting spaces. The selecting devices are rotatably connected to the base. The disk sets are respectively mounted on the selecting devices in the mounting specs of the disk holder and each disk set has a driving disk and at least one driven disk. The at least one interfering element is mounted securely on the disk holder and each of the at least one interfering element has a mounting tab and two elastic panels.

Abstract: A display system includes an electronic device, a display device, a power line and two converters. The electronic device is used to provide image data, and the display device displays images according to the image data. The first converter is coupled to the electronic device and plugged to a first power socket for receiving the image data sent by the electronic device and power from the power line, combining image signal and power signal and transmitting the combined signal to a second converter via the power line. The second converter is coupled to the display device and plugged to a second power socket for receiving the power from the power line and the image data sent by the first converter and separating the signal to transmit the image data to the display device.

Abstract: A lock cylinder assembly has a base, multiple selecting disks and multiple disk sets. The base has an axis. The selecting disks are rotatably connected to the base along the axis of the base. The disk sets are operationally mounted along the axis of the base and are respectively connected to the selecting disks. Each disk set has multiple disks operationally mounted along the axis of the base. Accordingly, a lock cylinder assembly that can increase the difficulty of unlocking the lock cylinder assembly to improve the safety of using the lock cylinder assembly is provided.

Abstract: A dry treatment method for decreasing contact angle on an optical film surface, includes providing an optical film and subjecting the optical film to ozone treatment to increase hydrophilic groups on a surface of the optical film so as to decrease contact angle on the optical film surface. The optical film treated with ozone will increase hydrophilic groups on the surface of the optical film to decrease its contact angle thereon. This method is able to reduce disadvantage of higher expense and inconvenient use in prior art of wet method.

Abstract: A multimode key system provides a multiple of keys for multimode control, wherein only desired function keys are shown on the control panel at a time, and whereby the operation thereof can be much simplified. The key system can be a touch panel or a pressure sensing panel, which characterized in a shifting unit integrated with an outer shell. The shifting unit can shift the a printed keyboard or a keyboard display grid board, so that the windows on the grid board display a set of corresponding keys on the printed keyboard, and thereby a user can see and touch the keys to operate a corresponding appliance or an industrial device.

Abstract: A soft stop-proof hook head of a measure tape is located at one end of the measure tape and comprises a ruler hook. A surface of a ruler hook is enclosed by a soft elastomer. The soft elastomer is made of a flexible material. When the soft elastomer is pressed, it generates an elastic resistance; in measuring, the ruler hook is coupled to a measured bench mark of an object to be measured with a slide-stop effect. Moreover, the soft elastomer is extended with a slide piece for enhancing the slide-stop effect.
