Provided is a fully automated web service with location based services generally involved in transmission of situational location dependent information to automatically located mobile receiving data processing systems. The web service communicates with a receiving data processing system in a manner by delivering information to the device when appropriate without the device requesting it at the time of delivery. There are varieties of configurations made by different user types of the web service for configuring information to be delivered, and for receiving the information. The web service maximizes anonymity of users, provides granular privacy control with a default of complete privacy, and supports user configurable privileges and features for desired web service behavior and interoperability. The web service is fully automated to eliminate human resources required to operate services. Integrated with the web service are enhanced location based services providing map solutions, alerts, sharing of novel services between users, and complete user control for managing heterogeneous device interoperability through the web service.

System and method for anonymous location based services

Systems and methods for positioning and navigating an autonomous vehicle (102,310) allow the vehicle (102,310) to travel between locations. A first position estimate (112) of the vehicle (102,310) is derived from satellites (132-170,200-206) of a global positioning system (100A) and/or a pseudolite(s) (105). The pseudolite(s) (105) may be used exclusively when the satellites (132-170,200-206) are not in view of the vehicle (102,310). A second position estimate (114) is derived from an inertial reference unit (904) and/or a vehicle odometer (902). The first and second position estimates are combined and filtered to derive a third position estimate (118). Navigation of the vehicle (102,310) is obtained using the position information (414), obstacle detection and avoidance data (416), and on board vehicle data (908,910).

Integrated vehicle positioning and navigation system, apparatus and method

An apparatus and method for navigating a vehicle along a predetermined route use route data and path data to define the predetermined route. The route data represents one or more contiguous path segments between adjacent nodes along the predetermined route. The path data includes postures of the vehicle along each of the path segments. The postures define the desired position, heading, curvature and speed of vehicle at various locations along the path segments. The apparatus and method use the posture information to generate and track a path thereby allowing the vehicle to navigate along the predetermined route.

Apparatus and method for autonomous vehicle navigation using path data

A sensing unit, such as a camera, or the like, senses the conditions of articles and mobile existences, including humans, in a life space, such as a house of a household, or the like. An article management/operation server manages, on an article database, attribute information of the articles, which include operators, etc., according to the information from the sensing unit. The server receives a user's instruction input through a console unit and refers to the article database to convert this instruction to a control command, which is then transmitted to a life-support robot.

Article handling system and method and article management system and method

Positioning system for locating a mobile body comprising a plurality of earth based spread spectrum (SS) broadcasting stations arranged geographically in a cellular pattern. Each SS broadcasting station include a modulator providing a channel signal structure which is substantially orthogonal with respect to adjacent stations in the cellular pattern, each channel signal including navigation beacon data including a unique beacon identification, station latitude and longitude, time_slot and phase characterizations and selected parameters of adjacent stations. In one embodiment, each modulator provides a chirped SS signal in which the navigation beacon is a frequency tone that is repeatedly swept over a selected frequency band for each station. In a further embodiment, each modulator provides a GPS like direct sequence SS signal in which the navigation beacon is a PN coded broadcast. A receiver on the mobile body receives the SS signals from at least three of the SS broadcasting stations and determines the location thereof. A fourth SS broadcasting station provides altitude CPS satellite signals can be used for timing control.

Cellular positioning system (CPS)

A vision navigation system for a mobile robot 21. The mobile robot has a plurality of light beacons 3, 5, 7 mounted on it to identify its location to fixed overhead television cameras 1 having a predefined viewing area. Navigation commands are generated by finding present robot location and transmitting new coordinates via the beacons which are used both for communicating with a master station and to locate the mobile apparatus. There are a minimum of three navigation beacons which are arranged in a tnangular pattern to enable robot direction to be determined, even when some beacons are obstructed from view of overhead cameras. The television system uses a gray scale image and has a video bus that transmits the actual pixel value synchronized with a pixel clock.

Vision navigation system for free-roaming mobile robots

A communication system for a mobile apparatus includes a means for communicating commanded destination to the mobile apparatus. The mobile apparatus includes a plurality of beacons that are used for both communicating with a master station and as a means of locating the mobile apparatus by the master station. The location of the mobile apparatus is used to generate commands which are transmitted to the mobile apparatus by light emitting diodes such that the light emitting diodes mounted on the mobile apparatus are used for both navigation purposes and communication.
