  • Patent number: 7965628
    Abstract: A data transmitting method for wireless communication system applied in a transmitting device for transmitting a number of data packets to a receiving device is provided. Firstly, n data packets are transmitted to the receiving device during the first time period, wherein n is a nature number. Next, the first accumulated number is recorded, wherein the first accumulated number denotes the times of resending the n data packets during the first time period. Then, determine that whether the first accumulated number exceeds a predetermined value or not. If the first accumulated number exceeds the predetermined value, then other communication methods are adopted and the method carries on transmitting the remaining data packets; if the first accumulated number does not exceed the predetermined value, the first accumulated number is cleared, and the method carries on transmitting the remaining data packets to the receiving device.

  • Patent number: 7925277
    Abstract: The invention provides a positioning system of positioning a wireless communication apparatus. The positioning system transmits and receives positioning signals which have different frequency bands and generates corresponding positioning values according to the positioning signals. The positioning system then judges and selects positioning values which have less error from the generated positioning values, and calculates an average value of the selected positioning values. Therefore, positioning of the wireless communication apparatus will be more precise. Furthermore, if the positioning system is implemented in a radio-wave-based wireless communication environment, the N positioning signals can be polarized in a linear polarization way, a left-handed circular polarization way or a right-handed circular polarization way, so as to reduce the environmental impact to enhance precision of the positioning.

  • Patent number: 7920130
    Abstract: The invention discloses a touch panel capable of identifying fingerprints. The touch panel includes a touch layer and a fingerprint sensing layer. The touch layer is used for sensing a specific location touched by a finger. The fingerprint sensing layer is disposed under the touch layer and includes a storage unit, multiple receiving modules, multiple transmitting modules, and a control module. The storage unit stores a first fingerprint data corresponding to the finger. Each receiving module respectively corresponds to one of the transmission modules. According to the specific location, one of the transmission modules transmits a signal, and the signal is then reflected by the finger to the corresponding receiving module. The control module converts the signal received by the receiving module into a second fingerprint data and then determines whether the second fingerprint data conforms to the first fingerprint data.
