Abstract: A visual inspection method of a curved object executed by a visual inspection system. The visual inspection system includes a robotic arm, a camera mounted at a tail end of the robotic arm, a fixing unit mounted under the camera, and a control unit electrically connected to the robotic arm and the camera. Specific steps of the visual inspection method of the curved object are described hereinafter. Fix a curved object which is to be inspected by the fixing unit. Capture the object which is to be inspected with a plurality of groups of preset parameters by the camera. Use the control unit to calculate a better shooting parameter. Use the better shooting parameter by the camera to proceed with visual inspections of the curved objects which are to be inspected in batches.

Abstract: An obstacle avoidance method for a robot arm is provided, including a modeling step, a collecting and evaluating coordinates step, an obtaining control parameter step, an establishing an occupation function step, and a finding an obstacle avoiding posture step. The present invention pre-stores the data obtained in performing the modeling step, the step of collecting and evaluating coordinates, the step of obtaining control parameter, and the step of establishing the occupation function into a database, thereby allowing the robot arm to quickly evaluate whether a collision behavior will occur in subsequent execution of a task. If a collision will occur, the robot arm executes the step of the finding the obstacle avoiding posture to dodge obstacles. The invention uses a non-contact approach for anti-collision design, which can improve the shortcomings faced by the existing contact type anti-collision design.

Abstract: A system for the intelligent obstacle avoidance of multi-axis robot arm includes a multi-axis robot arm and a host device. The multi-axis robot arm includes a plurality of knuckles and a plurality of connecting arms. The plurality of the connecting arms are alternately connected with the plurality of the knuckles. The host device is electrically connected with the multi-axis robot arm. The host device includes a database device, an operation control module and a signal transmission module. The database device, the operation control module and the signal transmission module are electrically connected. The signal transmission module transmits a control signal to the multi-axis robot arm for performing an optimum obstacle avoidance posture.

Abstract: A protective case for a tablet computer includes a main body for receiving the tablet computer therein and an inserting connector disposed in the main body. The main body has a receiving cavity for receiving a battery. The inserting connector is capable of electrically connecting the tablet computer with the battery when the tablet computer and the battery are received in the main body. Therefore, the tablet computer can be used in a longer continuous time by means of the battery providing electricity to the tablet computer.

Abstract: Disclosed is a projecting handheld game console and operating method thereof. The projecting handheld game console comprises a main body and a game handle to control the main body. The main body comprises a basic part and a projecting part which is fold connected to the basic part. The surface of the basic part has a display screen to display game images, and the projecting part has a projecting module to project and enlarge the game images. The projecting handheld game console can always adjust the height of the projector of the picture and overcome the shaking of the current handheld game consoles, then really satisfy a majority of gamers to see large screen gaming effects and to play together.

Abstract: A computer mouse is connected to a host system and includes a mouse body, and a connecting unit, a function-key-inputting unit, a touch-screen module, and a control module assembled on the mouse body. The connecting unit connects the mouse body with the host system for signal communication. The function-key-inputting unit transmits function-key-inputting instructions to the host system via the connecting unit. The touch-screen module is provided for displaying graphical information and detecting input instructions. The control module receives the function-key-inputting instructions and signals of the touch-screen module and transmits the instructions and signals to the connecting unit. The mouse can provide both regular functionality of a typical mouse and touch-controlling functionality via the touch-screen module. Incorporating with the host system, the mouse can provide a keyboard function, a hand-writing function, and a search function for convenience of operating and using.

Abstract: An electronic apparatus includes a display screen, a physical button, a touch pad separated from the display screen, and a processor. The touch pad is segmented into a first touch area, a second touch area and a third touch area. The processor judges an action of the physical button to select one of functions of the electronic apparatus and controls the display screen to show a selected function, the processor judges a track from the first touch area and through the second touch area and to the third touch area to operate the selected function and controls the display screen to show an operating result. Therefore, the operation method of the physical button and the touch pad is the same as a larger touch screen.
