Abstract:
A portable electronic apparatus is connected to a power supply device via a transmission line, and it includes a designated connector, a charge control circuit, and a judgment circuit. The designated connector includes five terminals respectively corresponding to five pins of a USB connector of the power supply device. When the power supply device is connected to the portable electronic apparatus, the first terminal of the designated connector is logic high, the fourth terminal of the designated connector is logic high, and the third terminal of the designated connector is logic high after pulling up the voltage level of the second terminal, the judgment circuit pulls down the voltage level of the third terminal and detects the voltage level of the third terminal so as to generate a determining result for determining a type of the power supply device.
Abstract:
A global positioning system device and an ionosphere error estimation method thereof are provided. The global positioning system device is connected to a plurality of dual-band base stations, and receives a plurality of ionosphere pierce point coordinates and a plurality of ionosphere errors from the dual-band base stations. The global positioning system device calculates a user ionosphere error by an interpolation method based on the ionosphere pierce point coordinates and the ionosphere errors of the dual-band base stations and a user ionosphere pierce point coordinate of the global positioning system device.

Abstract:
A handheld mobile phone includes at least two buttons, a logic circuit, and a processing unit, wherein each button is used for performing at least one specific function. The logic circuit is coupled to the at least two buttons for generating a corresponding specific signal when one of the at least two buttons is pressed alone, and for generating at least a control signal when all of the at least two buttons are pressed. The processing unit executes the specific function of the pressed button according to the corresponding specific signal. When all of the at least two buttons are pressed, the processing unit controls the handheld mobile phone to enter a reset state from an operating state according to at least the control signal.
Abstract:
A detachable adapter is provided for being detachably connected to a data bus of a receptacle of a portable device to form a portable system. The adapter includes a conversion circuit and can inform the portable device that whether a power source is available and inform the portable device of connection status of the adapter through the data bus. The portable device can be connected to the power source through one of the receptacles of the adapter so that the portable device is powered or charged, and the portable device can be connected to at least one client device through the other receptacle of the adapter simultaneously.
Abstract:
A cabinet door buffer bar includes a hollow tube, a shaft, an elastic element and a sliding member. The sliding member and the inner wall of the hollow tube form different intervals there between so that a resilient member mounted thereon receives varying constraints and generates different buffer forces in different moving directions thereby provides the cabinet door a required buffer force to avoid generating annoying noise and incurring damages during closing of the cabinet door.

Abstract:
A longitudinal-slide door controlling mechanism is provided to improve door controlling for large vehicles, such as buses. The door controlling mechanism is designed to longitudinal-slide to save space-occupied by the door and enhance safety. The mechanism includes a track, a slider group, a flexible transmission group, and a drive element. The flexible transmission group is used to drive the slider group to move along the track. And the track is attached to the bus body. Therefore the bus door is driven to longitudinal-slide along the bus body. The space-occupied caused by the conventional rotary door is saved. Also, the passerby struck by the door during opening would be eliminated.

Abstract:
A touch-controlled electronic apparatus includes a touch screen, and the touch screen includes a first area used as touch buttons and a second area used for displaying images. A method for controlling the touch-controlled electronic apparatus includes the steps of: detecting whether the touch screen receives a touch signal; when detecting that the touch screen receives the touch signal, determining whether a touched position of the touch signal is located on the first area to generate a determining result; and determining to trigger a first interrupt request or a second interrupt request according to the determining result.
