A representative method includes: obtaining initial location information; computing initial moving information based upon the sensor readings; computing estimated location information based on the initial moving information and the initial location information; acquiring geographical location readings if a location update condition is satisfied; generating reference location information based on the geographical location readings acquired; comparing the estimated location information with the reference location information to obtain a deviation information; computing a calibrated moving information based on the estimated location information and the deviation information; and computing a calibrated location information based on the deviation information, calibrated moving information and the estimated location information.

Abstract: An operating method of a display device includes controlling a shift of a cursor of a user interface reference frame according to a shift of the pointing device with reference to an initial point in a 3D spatial reference frame; and updating a position of the initial point in the 3D spatial reference frame according to an updating signal. An advantage of the present invention is when the operating range is changed, reference coordinates utilized by the pointing device are appropriately adjusted, so as to lower the affect of offset, allowing the pointing device to be applied in different areas/directions without having the cursor displayed on the display device to incorrectly reflect shift of the pointing device.

Abstract: A power consumption measuring device includes an analog-to-digital converter and an arithmetic unit and serves to convert a current signal supplied to a load into a measurement digital signal by the analog-to-digital converter, send the measurement digital signal to the arithmetic unit for measuring a power consumption level of the load. The power consumption measuring device is characterized in that: the arithmetic unit selects a current gain value and a correction compensation value based on a current range into which the measurement digital signal falls and adapted to adjust a gain value of the analog-to-digital converter for reducing an error rate and enhancing accuracy of the next measurement digital signal.

Abstract: A motion sensing system includes a hand-held device and a receiver device. The hand-held device includes a microcontroller, a G-sensor (one 3-axis accelerometer), only one 2-axis gyroscope, and a wireless transmitter. The receiver device is preferably a dongle and includes a microcontroller and a wireless receiver. A first axis of the 2-axis gyroscope is parallel to the Z axis of the hand-held device and the second axis of the 2-axis gyroscope forms an acute angle ? with the X axis of the hand-held device. The acute angle ? allows the microcontroller of the receiver device to calculate rotational data around each of the three axis of the hand-held device.

Abstract: A method for producing a mapping tool, a video game system for a stand-alone computer having the mapping tool and operation method thereof is disclosed. The mapping tool is created by means of linking a remote motion signal generated from a remote device which is operated by user with an input source signal from a conventional input source motion mapping table. User may operate the video game system for the stand-alone computer through the mapping tool. The present invention employs the mapping tool to replace conventional input source motion mapping table, thereby providing natural ergonomic and consistent usage of existing PC games or games for stand-alone computer having the input source motion mapping table.

The motion sensing device may include an accelerometer, a rotational sensor, a microcontroller, and an RF transmitter. The microcontroller may output processed motion data to the receiving device. The receiving device may include an RF receiver, a microprocessor, and a Universal Serial Bus interface for connection to a computer. The receiving device's microprocessor may output the processed motion data to motion mapping software. The motion mapping software may map the motion data to a corresponding predetermined input event defined by the motion mapping software and transmit a control signal back to the receiving device's microprocessor indicating the corresponding predetermined input event. Upon reception of the control signal from the mapping software, the receiving device's microprocessor may generate a hardware input event according to the control signal and transmits the generated hardware input event back to the computer.
