Minh-Tri Do Khac has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9948752
    Abstract: A method includes receiving a data packet transmitted by a near field communications (NFC) device at a NFC controller. Whether the data packet includes application identifier routing information is determined, and based thereupon the data packet is routed to a default application identifier routing address based on a look-up table lacking an application identifier routing address associated with the application identifier routing information. Whether the data packet includes protocol routing information is determined based upon the data packet lacking the application identifier routing information, and the data packet is routed to a default protocol routing address based upon the look-up table lacking a protocol routing address associated with the protocol routing information, using the NFC controller. The default application identifier routing address is different than the default protocol routing address.

  • Patent number: 9390300
    Abstract: An NFC-enabled device (12) comprising a host (22), an NFC interface (26) and an RF transceiver (24) configured to emit a first RF field (46) to power-up one or more in-range RF barcodes (16, 60), the NFC-enabled device (12) being configured to detect the presence of an RF barcode (16, 60) upon powering it up and being configured to read data (48, 62 ) from the one or more detected, in-range RF barcodes (16, 60), characterized by the NFC-enabled device (12) periodically (42) emitting the first RF field (46) and being configured to transmit only changes (64) in the read data (48, 62) from the or each RF barcode (16, 60) to the host (22). The invention therefore presents several advantages, namely: it can improve the user's experience by keeping the listen mode active, even in the presence of a nearby Kovio Tag; and it can save battery power by performing a periodic Kovio tag detection instead of a continuous one.

  • Patent number: 7177951
    Abstract: Address management methods and apparatus are provided for a node serving as peer group leader for a peer group of nodes in one level of the hierarchy of a PNNI hierarchical network, whereby the peer group leader represents the peer group to one or more neighboring nodes in the next level up of the hierarchy. The peer group leader has a memory (2) for storing peer group topology data (4), comprising address data which is supplied to the peer group leader from nodes in the peer group and represents addresses for access by the network, and peer group leader topology data (5), comprising address data which is supplied to said neighboring nodes by the peer group leader and represents addresses accessible via the peer group.
