Patent number: 8169985Abstract: The application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.Type: GrantFiled: February 14, 2006Date of Patent: May 1, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Chun-Ting Chou, Javier Del Prado Pavon, Sai Shankar Nandagopalan

Patent number: 8095565Abstract: Metadata is used to create customized user interface (UI) portions for an application. The metadata may be XML-based and can be interpreted and then rendered to implement a customized UI that also supports data binding between data and the UI controls. Once created, the metadata is processed by a rendering engine to display the UI controls. An interpreter may be used to interpret the metadata file before it is sent to the rendering engine. Neither the rendering engine nor the interpreter needs knowledge of the host application and provides support for arbitrary metadata driven UI. The metadata schema may include mechanisms to create custom controls for the UI; programmatically modify the UI controls by providing access to a code-behind assembly as well as support event handling for the UI controls.Type: GrantFiled: May 5, 2006Date of Patent: January 10, 2012Assignee: Microsoft CorporationInventors: Patrick M. Dengler, Arvind K. Krishnan, Jagdish Singh, Lawrence M. Sanchez, Sai Shankar, Satish Kumar Chittamuru, Zoltan Pekic, Nabarun Mondal, Namendra Kumar, Ricard Roma i Dalfó

Patent number: 7787434Abstract: The present invention provides a method (100), access point (20) and program product (35) for providing airtime and bandwidth fairness in wireless networks. To provide bandwidth fairness, a more fragment bit is set in a set of packets (46C) received by an access point (20) so that the packets of the set of packets (46C) can be transmitted to its destination (46C) successively (i.e., without back-off). To provide airtime fairness, upon receiving a packet (34) destined for a wireless station (22A), the access point (20) will calculate an airtime requirement for transmitting the packet (34), set a time counter (50) based on the airtime requirement. Thereafter, it will be determined whether the packet (34) can be transmitted to wireless station 22A before the time counter (50) expires. If not, transmission of the packet (34) will either not occur, or the packet (34) will be split into a set of fragments (48) for transmission.Type: GrantFiled: July 29, 2004Date of Patent: August 31, 2010Assignee: Koninklijke Philips Electronics N.V.Inventor: Sai Shankar Nandagopalan

Patent number: 7756089Abstract: Wireless stations (108-1-108-N) contending for exclusive access for a predetermined period of time (S232) to transmit on a communication medium (112) are regulated by a common external controller (104) using a single timing parameter (S204). Attempts at transmission access are preceded by respective delays that are expired simultaneously and at a common rate by the stations at times when the stations sense the medium to be idle (S224). The delays are pseudo-randomly selected to avoid collisions among stations in their respective access attempts (S208). Default, initial values of the respective delays (S204) applied to the stations, when multiplied by the respective expected number of transmission attempts by the stations over the long term over periods of time when no transmission attempt is unsuccessful, yield respective products equal to a constant value common to all stations (S312). The default values therefore serve as a knob by which the controller regulates air time opportunity.Type: GrantFiled: August 23, 2004Date of Patent: July 13, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Chun Ting Chou, Sai Shankar Nandagopalan, Javier Del Prado Pavon

The Beaconing protocol defines initializing an ad hoc network by means of starting a Beaconing Period, joining an existing Beaconing Period of ad hoc network and resolving collisions during the Beaconing Period.Type: GrantFiled: February 2, 2005Date of Patent: May 25, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Javier Del Prado Pavon, Amjad Soomro, Sai Shankar Nandagopalan, Zhun Zhong, Kiran Challapali, Joerg Habetha, Guido Hiertz

Patent number: 7711717Abstract: Recurring appointment items in a calendaring application are synchronized and recorded in a backend Line Of Business (LOB) service. Items marked in the calendaring application for time recording are used to create a recurring bound item with extended properties. A sweeper module scans on every run the mailbox for such recurring bound items. Occurrences of bound recurring appointments, which occur between the last scan and the current scan, are determined and detached from the corresponding recurring series, such that standalone bound items, are created for such occurrences that can be recognized by an LOB application. Entries for bound items are retrieved from a client data store and synchronized it with the backend LOB service through a create, update, or delete operation request.Type: GrantFiled: March 20, 2007Date of Patent: May 4, 2010Assignee: Microsoft CorporationInventors: Rakesh Gupta, David Koronthaly, Burra Gopal, Rolando Jimenez Salgado, Shyam Sundar Jayshankar, Satish Kumar Chittamuru, Himesh Shah, Arvind Kumar Krishnan, Sushil Kumar, Sai Shankar, Ashish Kumar Singhal, Jagdish Singh
