  • Publication number: 20230254917
    Abstract: A method for Bluetooth inquiry/paging and a communication device therefor are provided. The method includes transmitting a plurality of inquiry/paging messages in a transmission time slot to inquire/page a peer device, wherein, the number of inquiry/paging messages is greater than two; and activating a plurality reception windows in a reception time slot to receive response messages from the peer device. The invention also provides a corresponding communication device. The invention reduces the time required for inquiry/paging to the peer device, thereby reducing the time it takes to establish a Bluetooth connection between the two devices.

  • Patent number: 9196256
    Abstract: A data processing method for performing data processing on wireless received data and an associated data processing apparatus are provided, where the data processing method is applied to an electronic device. The data processing method includes the steps of: wirelessly receiving a plurality of packets corresponding to a same set of speech data from another electronic device; and selectively performing error correction operation on at least one of the plurality of packets to obtain the set of speech data, wherein whether to perform the error correction operation is determined according to at least one characteristic of the plurality of packets. More particularly, the error correction operation is selectively performed for at least one scenario of a timing critical scenario and a re-transmission limited scenario.

  • Publication number: 20100161858
    Abstract: An address conversion system is applied for a numerical control device and connected between a software inner address unit and a hardware contact point address unit. The address conversion system includes an address editing unit and an address conversion unit. The address editing unit includes an address display module and an address editing module. The address display module is configured for displaying hardware device startup addresses stored in the software inner address unit via an address display interface. The address editing module is configured for displaying contact point addresses stored in the hardware contact point address unit via an address editing interface. The contact point addresses are capable of being amended in the address editing interface. The address conversion unit is configured for matching the hardware device startup addresses with the corresponding contact point address.
