A geographic based communications service system that includes a network and a plurality of access points connected to the network and arranged at known locations in a geographic region. One or more service providers or information providers may be connected to the network to provide services or information on the network. Content provided by the service providers may be based on the known geographic location of the user of a portable computing device (PCD). The known geographic location may be determined with a high degree of precision, using one or more access points and one of several different techniques. In one embodiment, the geographic location of the PCD may be determined within a radius of ten feet. Access points may be configured to determine the bearing of a signal received from a PCD, as well as the strength of the signal transmitted by the PCD. Access points may also be configured to send and receive signals with time stamps. These time stamps may be used to calculate signal travel time, thereby allowing a determination of the distance between an access point and a PCD. Each access point may include location circuitry. The location circuitry may include both analog and digital circuitry configured to perform the various methods used to determine the precise geographic location.

The invention provides a plasma processing apparatus in which ring-like conductors 8a and 8b are arranged closed to and along an induction antenna 1 composed of an inner circumference coil 1a and an outer circumference coil 1b. Ring-like conductors 8a and 8b are each characterized in that the radius from the center of the apparatus and the cross-sectional shape of the conductor body varies along the circumferential angle of the coils. Since the mutual inductances between the ring-like conductors 8a and 8b and the induction antenna 1 and between the ring-like conductors 8a and 8b and the plasma along the circumferential position are controlled, it becomes possible to compensate for the coil currents varied along the circumference of the coils of the induction antenna 1, and to improve the non-uniformity in the circumferential direction of the current in the generated plasma.

A system and related techniques automatically analyze Web search and other activity, to generate locality-selected results based on not just the user's location, but also the business or other content provider's location and the degree of local intent in the user's query. The locality or region to the user may be identified, for instance, by the presence of geographic clues or indicators in the general content of the Web site, for instance, the presence of ZIP codes, telephone numbers, town names or other semantic or other indicators which have some geographic connotation in search terms, key words or other query or semantic inputs. The user's degree of local intent may be automatically analyzed as well, for instance by the presence of terms such as “car repair” or “pizza restaurant” which may suggest the user intends to locate local goods, services or providers. The search service may then access a content database to identify ads or other media or content which match or correspond to the detected locality or region, such as ads for local restaurants, car dealerships, physicians or other services or products, and which correspond in location, working radius and degree of localness to the user's query. Because the delivery of localized search results according to the invention is specifically filtered for user-driven local intent, advertisements and other media or content may be delivered which better match the user's search objectives.

A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.

The present invention provides a method for preventing a driver of a motor vehicle from using a cellular telephone while the motor vehicle is in motion. The invention comprises a step of determining a position of the gear shift lever in such motor vehicle and generating a first signal when the position of such gear shift lever is moved to and remains in one of drive, overdrive, second, low, and reverse. Another step involves transmitting such signal generated in a previous step to a means disposed in a predetermined location on such motor vehicle for generating a reverse phase signal. Another step involves generating such reverse phase signal when such first signal is received by such means. A next step is transmitting such reverse phase signal for a predetermined radius from such predetermined location. A last step is preventing any cellular telephone transmission within such predetermined radius when such reversed phase frequency signal is being transmitted.

A method and apparatus for rapidly soliciting the help of nearby people in a crisis situation such as a kidnapping is disclosed. The invention allows a person such as a parent to alert people who are within a specified radius of the person to voluntarily assist in looking for a missing child, pet, elderly person or other party in the area immediately surrounding the site where the party was last seen. The system allows for this assistance to be solicited within seconds of recognition of the fact that the party is missing. The system operates over the public mobile phone network using available location based services (LBS) technology such as those mandated by the FCC for enhanced 911 mobile emergency calls. Users, once notified of the missing child, could log their locations into the system if they spot the child at a specific time after they receive the alert. The resultant child tracking record is reported to the initial caller periodically by mobile. In addition, local “hot spot” wireless networks based at retail stores, museums, amusement parks etc can also be used to specify the users' location. The alert signal received from a particular wireless hot point in a retail store, for example, would initiate a request for help in searching for the missing person to be broadcast to the same hot point in the same retail store or nearby hotspots over a network managed by a wireless hot spot aggregator or a wireless carrier.

A system and method is disclosed for forwarding location dependent messages from a message sender's mobile cellular device to an intended recipient's mobile cellular device. The method is principally practiced in a communication network comprising a plurality of mobile cellular devices having location determining capabilities such as triangulation and GPS. In an embodiment, the message sender identifies an intended message recipient and selects a geographic location and corresponding radius of circumference defining geographic pre-conditions for transmitting the location dependent message to the intended message recipient. The message is first transmitted to a central server which periodically monitors the geographic location of the intended recipient in real time or near real-time to determine if the intended recipient enters within the radius of circumference of the geographic location selected by the message sender. The message is transmitted from the central server when it is determined that the intended recipient has satisfied the geographic pre-conditions. In other embodiments, a cellular mobile device user is alerted when one or more contacts of the user arrives within a certain geographic proximity of the user.

A peer-to-peer (P2P) search request message may multicast from an originating peer to its neighboring peers. Each neighboring peer may multicast the request message in turn until a search radius is reached. Each peer receiving the request message may conduct a single node search. If the single node search is successful, a P2P search response message may be generated. Each receiving peer may filter duplicate messages and may multicast to less than 100% of its neighbors. Responses may be cached and cached responses sent in response to request messages, expanding the effective search radius of a given P2P search. The multicast probability for a neighbor may be a function of how frequently the neighbor has previously responded to a particular search type. To reduce abuse by impolite or malicious peers, in addition to rate-based throttling, originating peers may be required to solve a computationally expensive puzzle.

Disclosed is a visual and audio system for theaters including a spherical screen having a desired radius of curvature while having a surface reflectivity of 5-50%, and a projector located at a focal point of the spherical screen.

MAP responses (or RADIUS response) are translated to corresponding SIP commands that are forwarded to the mobile device, thereby completing the connection set up.

A check valve which is positioned in the vacuum air line of an internal combustion engine. The check valve includes a single-piece valve body having an outlet port and two or more inlet ports, with one outlet port located substantially in line with the inlet port and connected by a venturi tube. The second inlet port is separated from the main air flow line by the valve stem and a diaphragm which allows communication there between and prevents back pressure. The second inlet port communicates with the outlet port through the valve stem and a second venturi tube which provides a vacuum boost to a device, usually vehicle brakes, connected to the inlet. The use of seal diaphragms having a non-constant radius allows for faster recovery time for replenishment than prior art devices.

In a General Packet Radio Service (GPRS) network, a system and method of dynamically allocating an Internet Protocol (IP) address to a mobile terminal (MT) operating in the network. A Gateway GPRS Service Node (GGSN) requests IP addresses over the Gi interface from a Radius server in an IP-based network. A Conditional PDP Address (CPA) parameter is stored in the MT's Home Location Register (HLR) as part of the user subscriber data, and is passed to the GGSN during the GPRS Attach procedure. The CPA parameter indicates whether the subscriber is entitled to a backup IP address in case of failure to obtain one over the Gi interface, and whether the MT is a user of a real-time application. A timer in the GGSN sets a maximum time period (Ti) that the GGSN will wait for a response from the server, and a counter (Ni) sets the maximum number of requests that are sent. A Network Access Server (NAS) in the GGSN sends a request for an IP address from the GGSN to the server, and determines whether Ti expires without receiving a response from the server. If no response is received, the GGSN allocates an IP address. A public IP address is allocated only if the MT is a user of a real-time application. Otherwise, a private IP address is allocated.

A point-of-interest mapping search system that combines inexact string searches with a proximity search to provide an extremely high probability of return of a set of search results in an initial search response that are useful to the user. Relevance of any particular point-of-interest item in a combined inexact string / proximity is dependent on both (1) a quality of the name match; and (2) a proximity to the starting location (or other relevant search center point) of the POI search. The inexact string name / proximity search is performed efficiently by iteratively expanding a search radius around a given location, searching concentric circles of proximity until a specified target number of relevant results have been found. It is the combination of the use of a combined inexact string match together with a proximity search performed against a database of geo-referenced business names that provides advantageous results.
