  • Publication number: 20200106340
    Abstract: A system for relieving pressure from within a generator casing can include a generator shaft defining a shaft channel therein and at least one rotating valve disposed within the shaft channel of the generator shaft and in fluid communication with an interior of the generator casing and the atmosphere. The rotating valve is configured to allow fluid within the generator casing to flow through the generator shaft to the atmosphere in an open state and while rotating. The rotating valve is configured to prevent fluid within the generator casing from flowing in a closed state.

  • Patent number: 10584673
    Abstract: A turbine for extracting kinetic energy from a fluid includes a runner, a turbine-inlet having an entrance and an exit that is adjacent the turbine's runner, and a turbine-outlet having an entrance that is adjacent the runner and an exit. The runner extracts kinetic energy from fluid flowing through the turbine; the turbine inlet directs flowing fluid into the runner; and the turbine-outlet directs flowing fluid away from the runner. When fluid flows through the turbine, the fluid flowing through the turbine-inlet toward the runner flows around and adjacent the fluid flowing through the turbine-outlet away from the runner.

  • Patent number: 10537986
    Abstract: A tracking-enabled extended-reach tool system acting upon a workpiece. The tool system includes a gimbal positioned adjacent an opening in a surface, a sensor system, a computer control, and a display. The extended-reach arm has a first end, a second end, an end effector including a tool adjacent the first end. The extended-reach arm engages the gimbal for relative rotational movement and relative slidable movement through the opening positioning the end effector and the tool on a side of the surface opposite the second end. The sensor system is configured to measure a linear position of the extended-reach arm relative to the gimbal. The computer control receives signals from the sensor system indicative of the linear position of the extended-reach arm relative to the gimbal. The display is connected to the computer control and displays a representation of the workpiece and the tool relative to each other in real time.

  • Publication number: 20200003896
    Abstract: Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.

  • Patent number: 9049702
    Abstract: A base station allocates resources for peer-to-peer communications by creating or updating peer sets from measured performance information received from one or more stations. Based on current resource assignments in each timeslot and based on the peer sets, the base station determines excluded timeslots and preferred timeslots. The base station then marks potential resources in a portion of a resource allocation map. One of the potential resources is allocated for peer-to-peer communication between a transmitter station and one or more receiver stations.

  • Patent number: 8982846
    Abstract: Systems, methods and apparatus are provided for scheduling resources in Orthogonal Frequency-Division Multiple Access (OFDMA) communication networks for “direct link” or peer-to-peer communications among stations operating therein so that OFDMA resources can be allocated to a transmitter station for a peer-to-peer communication session with a receiver station such that near-far issues caused by peer-to-peer communication are reduced/avoided. The disclosed technologies can prevent peer-to-peer communication links using different sub-channels within the same time slot from creating near-far issues for other receiver stations that are within communication range.

  • Patent number: 8705382
    Abstract: A subscriber station (SS) utilizes uplink resources that have been assigned to it for communicating with an infrastructure station to exchange data with a neighboring SS while maintaining its link to the infrastructure station. This is accomplished by the SS receiving an uplink allocation from the infrastructure station, transmitting a subscriber-to-infrastructure station header and trailer to the infrastructure station using the modulation and coding scheme (MCS) assigned by the infrastructure station and also transmitting a subscriber-to-subscriber (S2S) message payload, optionally using a second MCS level appropriate for the link between itself and the receiving SS. The subscriber to infrastructure station message is composed so that it occupies the first m codewords and contains a header that describes the length of the subscriber to infrastructure station message.

  • Patent number: 8634352
    Abstract: Some embodiments are directed to a method and apparatus for performing resource negotiation in a station implementing a direct communication link with at least one other station on an Orthogonal Frequency-Division Multiple Access (OFDMA) data channel. The station scans sub-channels on the data channel for base headers included in predefined position in transmissions sent on the sub-channel. The station then decodes a base header in at least one selected sub-channel to obtain parameters of a channel reservation. The obtained parameters are stored in a channel utilization table. The station selects a resource on the data channel in at least one of time or frequency that the station has observed to be free using information from the channel utilization table. The station then begins a resource negotiation process about the selected resource.

  • Patent number: 8179873
    Abstract: A method and apparatus for quieting multiple channels is provided herein. During operation, transmission activity on each channel is analyzed and a best band is identified. Once the band is chosen, a wideband transmitter is utilized to transmit simultaneous reservation messages on consecutive channels simultaneously. Because a wideband transmitter is used to transmit simultaneous reservation messages on multiple consecutive channels, the above procedure quickly quiets multiple channels while minimizing the reservation duration of all channels as a result of quieting the channels.

  • Patent number: 8130736
    Abstract: A method and system for facilitating channel measurements in a communication network is disclosed. The method includes contending for a control channel to reserve a logical subchannel of a data channel. The control channel operates in a first frequency band and the data channel operates in a second frequency band. Further, the method includes sending an announce message on the control channel for announcing a reservation at a particular time period of the logical subchannel of the data channel when the contention for the control channel is successful, sending a channel sense message on the logical subchannel of the data channel at the particular time period to facilitate at least one other node to perform channel measurements based on the channel sense message, and monitoring the data channel and performing channel measurements based on at least one other channel sense message received from the at least one other node.
