Abstract: Architecture that provides a data structure to facilitate personalized ranking over recommended content (e.g., documents). The data structure approximates the social distance of the searching user to the content at query time. A graph is created of content recommended by members of the social network, where the nodes of the graph include content nodes (for the content) and recommending member nodes (for members of the social network who recommended the content). If a member recommends content, an edge is created between the member node and the content node. If a member is a “friend” (tagged as related in some way) of another member, an edge is created between the two member nodes. Each node is converted to a lower dimensional feature set. Feature sets of the content are indexed and the feature set of the searching user is utilized to match and rank the search results at query time.

Abstract: An extensible architecture that enables developers to focus solely on the domain-specific nature of the stream processing algorithm to be implemented. It is positioned as an intermediary component between streaming data feeds and stream algorithms, thereby aggregating demand on data sources and hiding the complexity involved in managing active connections to different data sources. Per-algorithm stream throttling is provided so that individual algorithms do not get overloaded; thus, ensuring that algorithms receive fresh items from the data feeds to which the algorithms subscribe. Feed items can be discarded when an algorithm is not able to process the items in realtime to ensure that feed items are sampled at the fastest processing rate of the algorithm. Thus, a single instance of an algorithm can handle an entire data stream. Moreover, redundancy can be achieved by running the same configuration on multiple machines.

Abstract: A system and method that employs standardized data collection forms for use by health care providers and patients to enable efficient collection, storage and management of patient data for treatment of diseases, such as rheumatoid arthritis.

Abstract: A sling leather seat, seven inches wide, and approximately 29-30 inches long, having first and second end pieces and a center segment upon which a turret gunner can be seated, has a first ring between the first end piece and the middle segment, and a second ring between the second end piece and the middle segment. A leather waist belt is connected to the sling seat by a pair of elongated tethers connected between the first and second rings and the waist belt, respectively, including chains, cables and/or straps as the tethers which are of a length to allow the gunner to stand up, off the sling seat, but which will prevent the gunner from being ejected from the gun turret in the event of a vehicle rollover. The first and second end pieces of the sling seat are connected to a pair of rings, respectively, on the interior of the gun turret. The body belt in the preferred embodiment is tethered to the sling seat.

Abstract: A system and method controls entry or exit of a vehicle to or from a vehicle lot. A tag transmitter is adapted to be mounted on a vehicle for transmitting a wireless RF signal that includes vehicle data relating to the vehicle. A lane sensor is associated with a vehicle lane through which vehicles pass for at least one of entering and exiting the vehicle lot and is configured to receive wireless RF signals from the tag transmitter when the vehicle is in the vehicle lane, while substantially rejecting wireless RF signals from other tag transmitters mounted on other vehicles within the vehicle lot or in an adjacent vehicle lane. A processor is operatively connected to the lane sensor and receives and processes the vehicle data to validate and control the vehicle's entry or exit to or from the vehicle lot.

Abstract: Isolation is provided to two signal sources whose output signals are combined by the use of an outphasing technique. A first divider divides the signal from a first signal source into two signals and a second divider divides the signal from the second signal source into two additional signals. A first output of the first divider and a first output of the second divider are connected together by an attenuator and delay line which is used to cancel the leakage across a hybrid combiner. A second output of the first divider and second divider is applied to the hybrid combiner where the two signals are combined to obtain a combination signal that has enhanced isolation.

Abstract: A corporate amplifier is defined as and includes a plurality of N amplifier modules where N is a positive integer that is greater than one. The plurality of amplifier modules are driven by a power splitter which takes a signal that is to be amplified and divides it into N equal amplitude components. Each component is applied to a member of the plurality of N amplifier modules for amplification. The outputs of the power amplifier modules are combined by a power combiner that has N input terminals with each input terminal being connected to an output terminal of a member of the plurality of N amplifier modules. A fault detector detects failure of one or more of the plurality of N amplifier modules and provides a fault signal indicating thereby a failed amplifier module. A compensation circuit compensates both the power splitter and the power combiner means so that if a fault is detected in one or more of the plurality of N amplifier modules the performance of the corporate amplifier will be optimized.

Abstract: A wide band, feedforward, power amplifier circuit has greater stability when quadrature hybrid devices are used to match the output impedance of the power amplifier with the load.

Abstract: The performance of a wide band feedforward power amplifier circuit is enhanced when a phase intercept distortion compensation circuit is used to provide phase and amplitude matching between the signal amplifier and the feedforward path.

Abstract: This disclosure relates to an amplifier incorporating various devices for detecting parameters such as average power, peak power and signal voltage to be used to provide the feedback signals for automatic level control of an RF amplifier whose output signal is passed through an antenna coupler to an antenna. These detection devices allow normal operational level setting as well as minimizing the chance of overloads resulting in amplifier circuit failure during tuning conditions.
