  • Patent number: 10250298
    Abstract: A method and a system for communicating personal health data in a Near Field Communication (NFC) environment are provided. An NFC manager sets control information in an NFC Data Exchange Format (NDEF) for providing synchronized communication of personal health data between the NFC manager and an NFC agent. The control information may include a direction flag, a state flag, sequence identifier field, and request/response flag. The NFC manager writes the NDEF format including the control information and payload data into an NFC tag associated with the NFC agent. Subsequently, the NFC manager reads the NDEF record stored in the NFC tag and determines whether the NDEF record is written into the NFC tag by the NFC agent based on the control information in the read NDEF format. Accordingly, the NFC manager repeats the above mentioned steps if the NDEF record includes payload data of the NFC agent.

  • Patent number: 10021710
    Abstract: For a system providing coexistence between a WPAN coordinator and WLAN Access Point (AP), the WPAN coordinator requests WLAN AP for WPAN operation in a selected WLAN channel. The WLAN AP responds with the allocated time limit for which the WPAN operation can be performed. After expiration of the allocated time limit, the WPAN coordinator relinquishes the channel to the WLAN AP. A method addresses the operation of the WPAN system in 2.4 GHz ISM band when a non-overlapping WPAN channel selection is infeasible.

  • Patent number: 9032211
    Abstract: Methods for selectively securing records in a Near Field Communication Data Exchange Format (NDEF) message. A method includes placing a place marker signature record in the NDEF message. The place marker signature record is a modified signature Record Type Definition (RTD). A first set of records preceding the place marker signature record in the NDEF message is unsecured. The method also includes securing a second set of records following the place marker signature record. Another method includes placing a secured bytes field in the signature RTD. The secured byte field indicates a number of bytes of data to be secured preceding this field.
