Abstract: A system and a method for determining and disseminating current traffic information is presented. A traffic data compilation computer linked to a data network collects location data from mobile units, each of which is associated with an identification number. The computer compiles the location data, calculates the velocity of each mobile unit, compares the velocity of each mobile unit against speed limit data stored in a memory, and stores the difference. The traffic data compilation computer determines the traffic condition based on the difference between the velocity of each mobile unit and the speed limit. In addition, traffic data compilation computer may determine the fastest route between point A and point B under the current traffic conditions. Traffic data compilation computer determines the possible routes between point A and point B, retrieves the velocity data from a database, and derives the estimated travel time for each of the possible routes.

Abstract: A communications network is described having a class-based queuing architecture. Shared class queues receive packet flows from different customers. In one embodiment, there are eight classes and thus eight shared queues, one for each class. A scheduler schedules the output of packets by the various queues based on priority. Each customer (or other aggregate of packet flows) is allocated a certain space in a class queue based on the customers' Service Level Agreement (SLA) with the service provider. A queue input circuit detects bits in the packet header identifying the customer (or other criteria) and makes selections to drop or pass packets destined for a shared queue based on the customers' (or other aggregates') allocated space in the queue.

Abstract: An active matrix color sequential liquid crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix circuit has an array of transistor circuits formed in a first plane. Each transistor circuit is connected to a pixel electrode in an array of pixel electrodes having a small area. The counterelectrode panel extends in a second plane that is parallel to the first plane, such that the counterelectrode panel receives an applied voltage. The liquid crystal layer is interposed in a cavity between the two planes. In a preferred embodiment, an oxide layer extends over the pixel electrode array. The oxide can have a first thickness in a peripheral region around the array of the pixel electrodes and a thinner second thickness in a pixel electrode region extending over the array of pixel electrodes.

Abstract: A method for distributing locating-relevant information includes providing a GPS position of a client to a server on a data network, and returning location-relevant information by the server based on the specified GPS position. Such location-relevant information include travel or tourist information (e.g., locations of tourist attractions, hotels, or restaurants). Commercial information such as discount coupons or advertising selected based on the Client's GPS position can also be provided. Financial or business transactions can be conducted using the GPS position for authentication or identification.

Abstract: A display panel is formed using essentially single crystal thin-film material that is transferred to substrates for display fabrication. The transfer includes the step of transferring the semiconductor regions onto a stretchable substrate. The resulting circuit panel can be incorporated into a display panel with a light emitting or liquid crystal material to provide the desired display.

Abstract: Novel corrosion inhibiting compositions comprising a combination of amino thiol or amino disulfide compounds with acidic amino acid polymers inhibit carbon dioxide induced corrosion of ferrous metals in aqueous systems. Particularly effective inhibitor compositions are the natural amino acids cysteine and cystine and their decarboxylated analogues cysteamine and cystamine in combination with polyaspartic acid. The inhibitor compositions are particularly useful for preventing corrosion and scale formation in oil production applications.

Abstract: A system and method for voice interaction for location-relevant mobile resource management are disclosed. In one embodiment, a network server transmits a voice message to a voice device at a mobile unit upon detection that the mobile unit is within a predetermined distance of a certain location. Pursuant to another embodiment, the network server receives a voice request for location-relevant information from a user at a mobile unit and transmits responsive location-relevant information to the user as a voice message. The network server may also conduct certain actions responsive to voice requests received from users at mobile units. Users may receive information from the server via voice devices even when not located at a mobile unit.

Abstract: A system and method are disclosed for providing encryption of location data transmitted from a wireless device to a wireline network server. In one embodiment, the wireless device encrypts a payload, adds a header to the payload to form a data packet, encrypts the payload and the header of the data packet, and transmits the encrypted data packet.

Abstract: The disclosed network includes two rings, wherein a first ring transmits data in a clockwise direction, and the other ring transmits data in a counterclockwise direction. The traffic is removed from the ring by the destination node. During normal operations (i.e., all spans operational), data between nodes can flow on either ring. Thus, both rings are fully utilized during normal operations. The nodes periodically test the bit error rate of the links (or the error rate is constantly calculated) to detect a fault in one of the links. The detection of such a fault sends a broadcast signal to all nodes to reconfigure a routing table within the node so as to identify the optimum routing of source traffic to the destination node after the fault. Since the available links will now see more data traffic due to the failed link, traffic designated as “unprotected” traffic is given lower priority and may be dropped or delayed in favor of the “protected” traffic.

Abstract: Light emitting diodes (LEDs) and LED bars and LED arrays formed of semiconductive material such as III-V and particularly AIGaAs/GaAs material are formed in very thin structures using organometallic vapor deposition (OMCVD). Semiconductor p-n junctions are formed as deposited using carbon as the p-type impurity dopant. Various lift-off methods are described which permit back side processing when the growth substrate is removed and also enabled device registration for LED bars and arrays to be maintained.

Abstract: A method and system whereby two mobile units can locate each other is presented. A user connects an interface device, such as a personal digital assistance (PDA), a wireless phone, a laptop, or a pager, to a mobile unit. The mobile unit regularly obtains its location through a location-determining technology (e.g., GPS) and sends the location to a service provider computer. The service provider computer maintains a database of the current location of all the mobile units, and provides the location of mobile units to each of the mobile units. The mobile unit communicates with the service provider wirelessly through a communication network and a data network, for example the Internet.

Abstract: A method and a system using the Global Positioning System (GPS) to detect and report vehicle accidents are presented. GPS, which is currently used primarily for vehicle positioning, can be combined with wireless technology to automatically report accidents to third parties. A mobile unit placed or installed in a vehicle receives code sequences from the GPS satellites, converts the code sequences to positional information, and transmits the positional information to a server. The server derives the acceleration of the mobile unit from the positional information and compares the acceleration with a threshold value. In one embodiment, a microprocessor included in the mobile unit derives the acceleration and compares the acceleration with a threshold value. The threshold value represents acceleration that can be achieved only with an external force such as a collision.
