Abstract: Observation platform for using structured communications. A signal from a first communication device is received at a second communication device associated with a computer system, wherein a first characteristic of the signal corresponds to an audible source and a second characteristic of the signal corresponds to information indicative of a geographic position of the first communication device. A first user associated with the first communication device is recognized at the computer system. Context information for the signal is derived at the computer system associated with the second communication device. A copy of at least one characteristic of the signal is stored in a storage medium, wherein the copy of at least one characteristic of the signal is available for developing performance metrics. The signal is relayed to a destination derived from the context information.

The travel limiter operatively disposed on a coupler of the wheel end and configured to limit axial displacement of the sliding clutch ring towards the wheel assembly when engaging the drive shaft.

Abstract: The present invention allows telephone subscriber loops carrying data traffic between computer systems to be switched to an alternative connection through a data network, thereby unloading data traffic from the telephone network. The invention operates by means of a break switch, which selectively switches a plurality of subscriber loops between a central office switching system and a data network. The break switch is coupled to a concentrator which takes a plurality of inputs from the break switch and connects them to a smaller number of modems in a modem pool. The concentrator allows a subscriber line to connect to different types of modems within the modem pool, depending upon requirements of a particular subscriber line user. The modem pool connects through a network interface to a packet-switched network, such as the Internet. A number of different methods can be used to transmit a command to switch a subscriber loop from the central office switching system to the packet-switched network.

Abstract: The present invention allows a modem to operate in both the voice band, from 300 to 3400 Hz, and also in the ADSL band, which extends above 3400 Hz. Unlike conventional ADSL modems, the present invention avoids the computationally-intensive operations required to extract all the available band of a telephone subscriber loop. Consequently, the present invention can be implemented with low-cost modifications to existing voice band modems. The present invention thereby offers higher data transfer rates at a fraction of the cost of more complicated ADSL modems. The present invention also provides bypassing functions, which allow communications through a modem located at the telephone central office side of a subscriber loop to be switched through a packet-switched network, which is capable of accommodating high data transfer rates, instead of a central office switching system, which generally imposes unnecessary limitations on data transfer rates.

Abstract: The present invention provides a method and an apparatus for facilitating high bandwidth transmissions of data through a computer network. The invention uses communications through a routed network, such as the Internet, to establish a communication pathway through a connection-oriented network, such as an ATM or a frame relay network. This technique effectively exploits the universal addressing structure of routed networks, such as the Internet, to establish high bandwidth connections through connect-oriented networks. The present invention also facilitates selection of a connection-oriented network for data transmissions from a plurality of connection-oriented networks based upon parameters such as availability and costs. One embodiment of the present invention facilitates connections through mixed connection-oriented and routed networks, as well as through multicast networks. Another embodiment multiplexes several flows of data into a single connection through a connection-oriented network.

Abstract: DLL devices are built with multiple MAC address instead of a single MAC address, and provide a multiple virtual DLL interfaces to the upper layers (3-7) in a computer. This results in a new class of multi-function computers for attachment to a network system which take advantage of the multiple virtual DLL interfaces, to increase performance of the respective functions executed by the computer. Thus, a new network interface control apparatus and a new class of multi-function computer systems for attachments to networks are provided. The memory in the medium access control device stores a plurality of additional network addresses in addition to the assigned network addresses. The address filtering logic includes circuits responsive to the additional network addresses, such as logic for blocking a particular frame on at least one of the plurality of data channels when the source and destination address of a particular frame are found in the additional addresses stored in the memory.

Abstract: A method and apparatus for recording, categorizing, organizing, managing and retrieving speech information obtains a speech stream; stores the speech stream in at least a temporary storage; provides a visual representation of portions of the speech stream to the user; categorizes portions of a speech stream, with or without the aid of the visual representation, by user command and/or by automatic recognition of speech qualities; stores, in at least a temporary storage, structure which represents a categorized portions of the speech stream; and selectively retrieves one or more of the categorized portions of the Speech stream.

Abstract: A method and apparatus for increasing the capacity of present and future satellite communication systems transmits signals from correspondent pairs of earth stations simultaneously in channels that have at least a partial overlap in bandwidth. Each receiver at each earth station subtracts from the received composite signal the portion of the composite signal which was transmitted by the receiving earth station. This leaves a desired signal which corresponds to the signal transmitted by the other earth station of the correspondent pair and which is then demodulated. Each receiver at each earth station thus reconstructs an estimated target signal which has the amplitude, delay, frequency and phase of the signal as transmitted from the earth station and retransmitted by the satellite. The reconstructed target signal provides a very precise estimate of the portion of the composite signal transmitted by the earth station.
