  • Publication number: 20200271465
    Abstract: A travel coordination system determines a route for a rider using a public transit system and a provider. The travel coordination system may determine route that describes a public transit stop at which the rider exits the public transit system, and the travel coordination system can route a provider so that the provider transports the rider when the rider arrives at the public transit stop. The travel coordination system may update the rider's route after transmitting the route to the rider. The travel coordination system may determine a public transit vehicle on which the rider is traveling or predict the rider's destination. If multiple riders are traveling on the public transit vehicle and if those riders exit the public transit station using the same public transit stop, the travel coordination system may match those riders together for transport by a provider.

  • Patent number: 10492028
    Abstract: Embodiments of the present disclosure support improving determination of a location of a driver device that performs bandwidth constrained communication with a server, based on sensor data acquired by the driver device. The driver device reduces dimensionality of the acquired sensor data before transmitting the sensor data to the server over a communication network. The server receives GPS data and compressed sensor data from the driver device, and determines a quality metric related to the GPS data. Based on the quality metric, the server increases dimensionality of the compressed sensor data to reconstruct original sensor data acquired by the driver device. The server than augments the GPS data with the reconstructed sensor data, and determines location information of the driver device based on the augmented data.

  • Patent number: 8587320
    Abstract: A system, apparatus and method are provided for testing a secondary servo control circuit in a redundant control configuration. A first circuit is configured to receive a control signal and to control an attribute of an actuator based on the control signal using a first control input of the actuator. A second circuit is configured to test operation of an actuator circuit using a test signal. The actuator circuit includes at least part of the second circuit and a second control input of the actuator. The test signal is selected to avoid causing independent motion of the actuator. The actuator could be a dual coil servo valve, and the test signal could be a current (such as a DC current, an AC current, or a pulsed current) having a magnitude less than a bias current of the actuator.

  • Publication number: 20110029377
    Abstract: An improved system and method for forecasting an inventory of online advertisement impressions by sampling in a map-reduce framework is provided. In a map-reduce framework, samples of visitor profiles may be collected and matched to targeting profiles for displaying advertisements by distributed sample mappers. Sets of samples of visitor profiles matched to the targeting profiles may be mapped and distributed to reducer servers for integrating the samples collected by sample mappers into a reduction sample set for each targeting profile. Each reducer server may aggregate a count of samples of visitor profiles matched to a targeting profile, and the sets of samples of visitor profiles matched to a targeting profile may be integrated into a reduction sample set for each targeting profile. The sample reducers may forecast a targeting profile inventory for each targeting profile and output the targeting profile inventory with a reduction sample set of visitor profiles.

  • Publication number: 20110015999
    Abstract: Embodiments of the present invention provide for methods, systems and computer program products for utilizing a lattice structure in an advertisement serving system. The method according to one embodiment of the present invention comprises storing one or more advertisement contracts in a lattice structure. A request for one or more advertisements that satisfy one or more constraints is then received and within the lattice structure, a lowest level of one or more pools of advertisement contracts satisfying the one ore more constraints is located. A set of advertisement contracts is generated, wherein the set of advertisement contracts comprise one or more advertisement contracts from lowest level of the lattice structure. The method further comprises adding to the set of advertisement contracts advertisement contracts from the pools of advertisement contracts that are parent to the pools of contracts in the lowest level of the lattice structure.

  • Patent number: 7869890
    Abstract: A parallel operation keyboard (POK) which enables a user to provide multiple inputs simultaneously in managing a process control plant. A lock is provided to disable such simultaneous inputs. In an embodiment, multiple groups of keys are provided, with each group of keys being operable independently to modify the parameter value of a corresponding control loop. A network management station (NMS) and a server are designed to provide a suitable interface. In one implementation, each group of keys contains four keys respectively specifying increasing the parameter value, decreasing the parameter value, manual mode (in which the present level of the variable is controlled by the increase/decrease keys) and normal mode (in which the set point, i.e., the desired value, for the variable is controlled).

  • Publication number: 20100185515
    Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating an inventory pool that represents a number of impressions deliverable to all users, then determining, from multiple past orders for booking impressions, a hierarchy of parameters utilized to target users and a number of impressions deliverable to users characterized by the parameters. The inventory pool may then be partitioned into multiple inventory pools according to the hierarchy, where each inventory pool represents a number of impressions deliverable to users characterized by parameters associated with the inventory pool. The hierarchy of pools may then be stored to a database.

  • Publication number: 20100185484
    Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating several inventory pools, where each inventory pool represents a number of impressions deliverable to different groups of users characterized by attributes. Impressions deliverable to users represented by each inventory pool may be allocated to each inventory pool. Impressions that correspond to multiple pools may be distributed between the multiple pools. The inventory pools may be stored to a database. Afterwards, and order may be received. The order may include parameters that define an audience and a number of impressions. The number of impressions in the order may be allocated from pools in the database.

    Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating samples of representatives that represent impression inventory, where each sample represents a number of users to which impressions are deliverable. An order may be received. The order may include a number of impressions to book and target audience information. A cushion of impressions needed to guarantee delivery of the number of impressions ordered may be determined. The number of impressions ordered plus the cushion may be allocated from the samples. A contract including the target audience information, the number of impressions, and the cushion may be stored to a database.
