Abstract: A portable information handling system interacts with a game controller through either a direct connection at a wired interface at the sides of opposing controller housings and the information handling system housing or through a bridge having a bridge housing that directly couples to the controller housing as a bridge to the information handling system, such as with a wireless interface. During a sliding coupling motion, pins of the controller housing wired interface move across pins of the bridge or information handling system wired interface. Analysis of the interface signals through a sliding coupling motion identifies the type of controller housing, such as a controller housing with game input devices or with extra functions like speaker audio and supplemental battery power.

Abstract: A keyboard with a vibration function is provided. The keyboard includes a base member, an upper cover, a basic key structure and a vibration key structure. The vibration key structure includes a control module, a vibration keycap and an isolation element. The control module is fixed on the upper cover. When the control module is triggered, a vibration key signal is generated and a vibration action is provided. The control module is covered by the vibration keycap. The vibration keycap is exposed outside the upper cover. The isolation element is arranged between the control module and the upper cover. The vibration key structure is enclosed by the isolation element, so that the energy of the vibration action from the control module is isolated.

Abstract: The present disclosure relates to a data transfer method. First, a transmitting index of a file is generated on a data transmitting device using a transmitting data block and a size of the file. The transmitting index is then transmitted to a data receiving device. The data receiving device confirms if the transmitting index matches with one of a plurality of receiving indexes stored in the data receiving device. The plurality of receiving indexes respectively represents a plurality of receiving files stored on the data receiving device. The file is transferred from the data transmitting device to the data receiving device when the transmitting index matches none of the plurality of receiving indexes. The file is not transferred when the transmitting index matches one of the plurality of receiving indexes.

Abstract: A visual object tracking method includes the steps of: setting an object window having a target in a video image; defining a search window greater than the object window; analyzing an image pixel of the object window to generate a color histogram for defining a color filter which includes a dominant color characteristic of the target; using the color filter to generate an object template and a dominant color map in the object window and the search window respectively, the object template including a shape characteristic of the target, the dominant color map including at least one candidate block; comparing the similarity between the object template and the candidate block to obtain a probability distribution map, and using the probability distribution map to compute the mass center of the target. The method generates the probability map by the color and shape characteristics to compute the mass center.

Abstract: A method for establishing a wireless connection between an electronic device and a computer host is provided. Firstly, a near field communication between a NFC reader of the computer host and a NFC tag of the electronic device is performed. Then, a Bluetooth wireless communication between the electronic device and the computer host is performed, and the NFC tag is disabled. Consequently, the NFC tag is not repeatedly read by the NFC reader. In other words, the use of the electronic device is more convenient.

Abstract: An electrical device having a wireless route function is provided. The electrical device comprises a signal processing module, a wireless route module and a wireless transceiver module electrically connected to the signal processing module and the wireless route module. The signal processing module is configured to generate a first signal. The wireless route module is configured to create a route mode. The wireless transceiver module is configured to build a plurality of first wireless connections with a plurality of first electrical products according to the route mode, and transmit the first signal to the first electrical products via the first wireless connections so that each of the first electrical products executes a first action in response to the first signal.

Abstract: A keyboard device for use with a tablet personal computer includes a base body and an upper cover. The base body includes a handle and plural keys. The handle is integrally formed with the base body. The upper cover has a receptacle for accommodating the tablet personal computer. The upper cover is connected with the base body. In addition, the upper cover is rotatable with respect to the base body in order to open or close the upper cover of the keyboard device. When the upper cover of the keyboard device is opened, the tablet personal computer is stored within the receptacle, so that the user may input characters or symbols to the tablet personal computer by depressing the keys. Whereas, when the upper cover of the keyboard device is closed, the keyboard device may be carried by grasping the handle.

Abstract: A separable game controller includes a first handle, a second handle and a fixing member. The second handle includes a first sensor, a second sensor and a first controlling unit. The first controlling unit is electrically connected with the first sensor and the second sensor. The first sensor is used for sensing whether the first handle and the second handle are separated from each other. When the first handle and the second handle are separated from each other, the first sensor generates a first signal. When the first signal is received by the first controlling unit, the second sensor is enabled by the first controlling unit to generate a second signal. According to the second signal, a displacement of the second handle is sensed by the second sensor.
