Patent number: 8976767Abstract: A method of reducing data transfer while increasing image information over an 802.15.4 network includes obtaining an image with a sensor, modulating a representation of the image using a first 802.15.4 modem, sending the representation of the image to a coordinator, demodulating the representation of the image using a second 802.15.4 modem, and digitally enhancing at least one of the representation of the image and the image. A system for communication over an 802.15.4 network includes a sensor for obtaining data, the size of the data being at least an order of magnitude greater than the size of an 802.15.4 packet, a first 802.15.4 modem coupled to the sensor, a buffer for temporarily storing the data to allow transmission of portions of the data; the buffer being coupled to the sensor, a coordinator coupled to the sensor, the coordinator being capable of communicating with a computer, and a second 802.15.4 modem coupled to the coordinator.Type: GrantFiled: September 17, 2012Date of Patent: March 10, 2015Assignee: Simple Works, Inc.Inventors: Tom Black, Dale Mason, Robert Schneider, Paul Bricketto

Patent number: 8976691Abstract: A first communication device comprising memory in which data is stored may receive a request packet from a second communication device, measure received signal strength for the request packet, and determine whether to perform the requested search of the data stored in the memory based on the received signal strength and the power at which the request packet was transmitted. The search request packet may comprise a request to search the data stored in the memory, and a transmit power field that indicates a power at which the request packet was transmitted. The determining may be based on a result of a comparison between the received signal strength and a threshold and/or based on a comparison of a relative power and a threshold. The relative power may be calculated utilizing the received signal strength and the power at which the packet was transmitted.Type: GrantFiled: October 6, 2011Date of Patent: March 10, 2015Assignee: Blackbird Technology Holdings, Inc.Inventor: John Peter Norair

Patent number: 8976673Abstract: A method is implemented in a network element that functions as one of a plurality of controllers for one of a plurality of areas of a split architecture network. The controller provides a control plane for the area of the split architecture network where the controller is remote from a plurality of switches providing a data plane for the area of split architecture network. The controller facilitates optimized routing across the plurality of areas of the split architecture network by providing limited intra-area link cost data to other controllers of other areas of the split architecture network and to traditional routers of a network including the split architecture network. The limited intra-area link cost data provides costs of each possible shortest path traversal of the area of the controller without providing all internal link cost data.Type: GrantFiled: September 12, 2013Date of Patent: March 10, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Kiran Yedavalli, Neda Beheshti-Zavareh, Ying Zhang

Patent number: 8971212Abstract: A method for discovering resources includes identifying one or more geographically fixed transceivers with which a mobile device is in communication and through which the mobile device can communicate with other devices. A resource geographically associated with the identified one or more transceivers is identified. Identification occurs without regard to a signal strength or strengths experienced between the mobile device and the one or more transceivers. The mobile device is caused to display data corresponding to the identified resource.Type: GrantFiled: September 21, 2010Date of Patent: March 3, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Dhruv Tandon, Deny Joao Correa Azzolin

Patent number: RE45424Abstract: Methods and systems for reliable neighbor discovery in wireless ad hoc networks are provided herein. In one aspect, embodiments of the present invention provide methods and systems for analyzing the quality of a communication link. In embodiments, several factors affecting link quality may be incorporated in the analysis, and basic and/or complex statistical and/or probabilistic analysis may be used. In another aspect, embodiments of the present invention provide methods and systems for neighbor node discovery that adapt to network and/or node operating conditions and that dynamically maintain a neighbor node set at a given node according to these conditions. In a further aspect, embodiments of the present invention extend the utility of neighbor node discovery beyond the customary role of data routing support into the problem of deploying an ad hoc network by providing a display module for displaying node connectivity information.Type: GrantFiled: April 27, 2012Date of Patent: March 17, 2015Assignee: Social Perspective Mgmt, L.L.C.Inventor: Thomas Bronez
