The antenna array comprises a receiving antenna array having antenna elements for receiving a signal, wherein the receiving antenna array is arranged in a first one-dimensional array. The antenna array further comprises a transmitting antenna array having antenna elements for transmitting the signal, wherein the transmitting antenna array is arranged in a second one-dimensional array which is different from the first one-dimensional array.

Abstract: Some examples estimate time-varying range and clock offset between first and second transceivers that are moving relative to one another. The first transceiver transmits a first stream of symbols at a first succession of times according to a first clock, and receives from the second transceiver a second stream of symbols transmitted at a second succession of times according to a second clock. The first transceiver estimates arrival times and delays of symbols of the received second stream of symbols, and uses them to calculate first and second values describing a relationship between the estimated arrival times and delays of symbols. The first transceiver receives from the second transceiver third and fourth values describing a relationship between estimated arrival times and delays of symbols of the first stream of symbols. The first transceiver estimates the time-varying range and time-varying clock offset using the first, second, third, and fourth values.

Abstract: Systems and methods of the present invention provide for server(s) assigning section or list item classifications to price list or business data extracted from a website. The server routes each new task verifying the classification to a crowd worker, and the server receives a completed. The server calculates a crowd worker score for each crowd worker based on each worker's quality scores according to the worker's review of the classifications on a worker user interface. The server generates a quality model for predicting a task quality score for the task, according to an error score for the crowd worker. If the error score in the quality model is below a predetermined threshold, the server transmits the completed task to a task reviewer's client for review.

Abstract: Systems and methods of the present invention provide for one or more server computers configured to assign section or list item classifications to price list or business data extracted from a website. The server assigns section or list item classifications to price list or business data extracted from a website. The server calculates a crowd worker score for each of a plurality of crowd workers based on each worker's quality and speed scores for tasks reviewing the classifications on a worker user interface. If a crowd worker score for a worker is below a crowd worker quality threshold, each new task is routed to the worker, and the received task, when completed, is routed to a worker whose crowd worker score is above the crowd worker quality threshold for review.

Abstract: A system and method for automatically determining an amount of review a crowd-sourcing task needs after an initial review has been completed by a processing worker. An evaluation metric is automatically assigned to the work performed by the processing worker to determine the appropriate amount of human review required for a particular task. The evaluation metric may be calculated by accessing and evaluating a plurality of transaction categories related, but not limited to, worker characteristics, document characteristics and processing characteristics. Additionally, the evaluation metric may be used to determine compensation of the processing worker and whether a promotion or demotion is necessary. The system is also capable of balancing individual workloads based upon the evaluation metric.
