Method for Providing an Adaptive Wireless Ambient Service to a Mobile Device
TL;DR: In this article, a system for providing a wireless ambient service to a mobile end-user device operating on a Wireless Wide Area Network (WWAN) is described, which includes one or more device agents and an ambient service proxy server that cooperate to implement the service.

Opt-in and time limited bi-directional real-time location sharing
Tessa Husain,Christina Janczak +1 more
TL;DR: An opt-in and time limited bi-directional real-time location sharing (OTLBLS) system and method that enable individual users of the disclosed system to communicate, bidirectionally in real time while also sharing certain information including, for example, locations, messages and metadata is described in this paper.
Patent
Location positioning engine system and method
Michael A. Kerr,David Stewart +1 more
Abstract: A system for associating content with geographic boundaries, determining the location of a wireless handset relative to the boundaries, and delivering targeted content to the wireless handset is described. The application is configured to determine the location of the wireless handset based on the strength of signals received from the network components by the wireless handset. The application then filters content items by boundary and delivers at least one content item to the wireless handset when the wireless handset is located within the boundary.
Patent
Method and system for an ontology based request/reply service
TL;DR: In this article, an ontology-based request/reply service (RRS) is defined by the unique service indicated in the request, and instantiated dynamically as needed, according to an individual RRS ontology which establishes a syntactical and semantical framework dedicated to the unique services.
Patent
Motion-based configuration of a multi-user device
TL;DR: In this paper, an electronic device obtains first motion information describing motion of an accessory of a multi-user device that is in communication with a display, and obtains second motion information described motion of a user device associated with a first profile, wherein the motions of the accessory and the user device are detected during the first time period.

RADAR: an in-building RF-based user location and tracking system
TL;DR: RADAR is presented, a radio-frequency (RF)-based system for locating and tracking users inside buildings that combines empirical measurements with signal propagation modeling to determine user location and thereby enable location-aware services and applications.
Optimized Link State Routing Protocol (OLSR)
Thomas Clausen,Philippe Jacquet +1 more
TL;DR: The Optimized Link State Routing protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN and provides optimal routes (in terms of number of hops).
Journal ArticleDOI
The active badge location system
TL;DR: A novel system for the location of people in an office environment is described, where members of staff wear badges that transmit signals providing information about their location to a centralized location service, through a network of sensors.
Proceedings ArticleDOI
The Cricket location-support system
TL;DR: The randomized algorithm used by beacons to transmit information, the use of concurrent radio and ultrasonic signals to infer distance, the listener inference algorithms to overcome multipath and interference, and practical beacon configuration and positioning techniques that improve accuracy are described.
