Patent number: 8634771Abstract: Wireless devices that support bootstrapping of a peer-to-peer connection. The wireless devices may use an infrastructure mode connection to exchange security information, such as a PIN, used in establishing the peer-to-peer connection. This security information may be encrypted in accordance with a security protocol used by the access point and then may be applied in a security protocol used to establish a peer-to-peer connection. Such a bootstrapping capability supports operating scenarios in which devices that are communicating over an infrastructure network encounter an operation that requires transfer of large amounts of data and automatically transition to a peer-to-peer connection that provides better performance. With these techniques, a computing device may automatically connect to a display device and stream audio/video data to the display.Type: GrantFiled: June 15, 2011Date of Patent: January 21, 2014Assignee: Microsoft CorporationInventors: Amer A.

Patent number: 8542665Abstract: A method to add a new wireless device to a home network through one common interface administrator such as a TV hosting an application. A user simply inputs one identification code of the new wireless device to the TV using a remote commander. Since all wireless devices are registered through the same application regardless of their type, the setup experience is consistent to a user who is required to have no special knowledge. Through the process, the administrator TV obtains information of wireless devices sought to be registered in the home network, enabling the administrator TV to capture the network structure or topology, which may be used for further applications, without implementing dedicated protocols such as UPnP to collect the information.Type: GrantFiled: August 6, 2007Date of Patent: September 24, 2013Assignees: Sony Corporation, Sony Electronics Inc.Inventor: Tohru Doumuki

Patent number: 8532079Abstract: An access point transmits a preemptive peg packet when it has no data to transmit in order to maintain the contiguity of its transmission timing position with respect to the timing position of other contention-free sessions (CFS) transmitted by other access points in an existing, periodic sequence. The cyclic prioritized multiple access (CDMA) method establishes the transmission timing position of contention-free sessions (CFS) between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations. If an access point has no traffic, it will transmit a short, preemptive pegging packet and reset its backoff timer. In this manner, no gaps longer than the distributed coordination function (DCF) Interframe Space (DIFS) are left idle. This prevents other stations from using DCF contention to seize the channel, until all access points have completed one contention-free session (CFS) per periodic cycle.Type: GrantFiled: November 15, 2011Date of Patent: September 10, 2013Assignee: AT&T Intellectual Property II, L.P.Inventor: Mathilde Benveniste

Patent number: 8525645Abstract: A method of recognizing a tag in an RFID reader includes: obtaining a predetermined frame size in the case where throughput obtained by reflecting a slot length based on the remaining number of tags except for recognized tags within a frame progressing current tag recognition that substantially has a maximum value; and when the current frame size is different from the predetermined frame size, stopping the current progress of frame and changing the current frame size into the expected frame size. The method of recognizing a tag may further include when the current frame size is equal to the expected frame size, changing the current frame size into the frame size that does not cause a throughput inversion phenomenon for the remaining number of tags to be recognized within the frame progressing the current tag recognition. By the throughput inversion phenomenon, the occurrence of throughput loss can be prevented and the tag recognition time is reduced to recognize the tags at high speed.Type: GrantFiled: June 29, 2009Date of Patent: September 3, 2013Assignee: Gwangju Institute of Science and TechnologyInventors: Hyuk Lim, Jae-Hyung Jang, Yung-Kwan Kim
