  • Patent number: 11026662
    Abstract: For phase inversion-based ultrasound imaging with a transmit and receive circuit at an array, a unipolar transmitter is used to reduce the number of high voltage wires. Rather than adding a T/R switch or increasing connections by connecting the receive amplifier to a different electrode than the transmitter, two different receive paths from the element to the receive amplifier are provided. One path is used where the unipolar transmitter ends in one state (e.g., 0V), and the other path is used where the unipolar transmitter ends in another state (e.g., Vtx).

  • Patent number: 10970266
    Abstract: A method includes reading, by a capture engine, log data. The log data can be synchronously hardware-replicated. The log data reflects that an update was started for a database of a first site. The capture engine corresponds to a capture engine of a second site. The method also includes identifying, by the capture engine, the update. The method also includes determining whether the update was committed to the database of the first site. The method also includes replicating, by an apply engine, the update to a database of the second site based on the determining. The update is replicated to the database of the second site based on a determination that the update was committed to the database of the first site. The committed update corresponds to a consistent replication of updates across two or more databases that reside in multiple database management systems.

  • Publication number: 20210096959
    Abstract: Aspects of the invention include a continuous availability for workload and site switches with no data loss at unlimited distances in an active-active sites configuration. A non-limiting example computer-implemented method includes synchronously replicating commit records of changed workload data, by a processor, from an active site to a bunker site upon a workload data commit. The method asynchronously replicates committed transactions on changed workload data, by the processor, from the bunker site to a recovery site.

  • Patent number: 10949775
    Abstract: An airline operations system, controller and method reschedules flights affected by a disruption that precludes a planned schedule for the flights. The method includes obtaining data related to a scheduled origination and a scheduled destination for each of a set of passengers scheduled on the flights, generating a passenger connection network of connections between the scheduled origination and the scheduled destination for a subset of the set of passengers, applying at least one criterion to the passenger connection network and rescheduling at least one connecting flight based on the criteria. The system and controller solves a network flow problem to reschedule a subset of connecting flights to have a delayed projected departure time. Resulting output can include the set of delayed flights along with modified projected departure times, a set of flight cancellations and a set of passengers with missed connections.

  • Publication number: 20200370999
    Abstract: A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

  • Patent number: 10749159
    Abstract: A sensor system senses one or more characteristics of vehicles in a vehicle system with sensors disposed onboard the vehicles and communicate data representative of the one or more characteristics from the sensors to one or more of a controller or a control system of the vehicle system. The data communicated from the sensors onboard the same vehicle can be synchronously communicated with respect to the sensors onboard the same vehicle and asynchronously communicated with respect to the sensors disposed onboard one or more other vehicles in the vehicle system. The systems and methods can direct components disposed onboard a vehicle system to change operations, monitor data output by sensors operatively connected with the components, and determine which of the sensors are operatively connected with which of the components based on the operations of the components that are changed and the data that is output by the sensors.

  • Publication number: 20200226937
    Abstract: A vertiport system dynamically updates configuration of a vertiport based on predicted usage of the vertiport during a given time frame. The vertiport system predicts vertiport usage using flight data and estimated passenger demands and determines a desired number of parking pads and a desired number of final approach and takeoff (FATO) pads for the vertiport during the time frame. Based on the desired number of parking pads and the desired number of FATO pads for the vertiport, the vertiport system determines an updated configuration of the vertiport. According to the updated configuration, the vertiport system updates the configuration of the vertiport for at least a portion of the time frame.

  • Patent number: 10528501
    Abstract: Methods and systems of synchronizing events using a plurality of sequencing controllers are provided. For each sequencing controller, a serial communication bus (SCB) is monitored for a first reference level. Upon identifying that the SCB is at the first reference level for a predetermined period, a bit sequence indicative of an event position is broadcast to be arbitrated on the SCB. The SCB is monitored for the arbitrated bit sequence. Upon determining that the arbitrated bit sequence corresponds to the bit sequence of the event position, an event corresponding to the event position is enabled.

  • Patent number: 10510628
    Abstract: For multidimensional transducer array interconnection, circuit boards with electronics are stacked to form a surface for connection with the array. The surface of the circuit boards for connecting with the transducer array is metalized and diced. Rather than relying on small exposed traces, larger contact pads are formed by metalizing the surface and then dicing the surface. This forms an array of contact pads for connecting with the z-axis or other connectors for elements of the multidimensional transducer array.
