Abstract:

A circuit for counting in an N-bit string a number of bits M, having a first binary value includes N latch circuits in a daisy chain where each latch circuit has a tag bit that controls each to be either in a no-pass or pass state. Initially the tag bits are set according to the bits of the N-bit string where the first binary value corresponds to a no-pass state. A clock signal having a pulse train is run through the daisy chain to “interrogate” any no-pass latch circuits. It races right through any pass latch circuit. However, for a no-pass latch circuit, a leading pulse while being blocked also resets after a pulse period the tag bit from “no-pass” to “pass” state to allow subsequent pulses to pass. After all no-pass latch circuits have been reset, M is given by the number of missing pulses from the pulse train.

705 141

Abstract:

This specification relates to tracking phone calls related to online content items. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a probability that a call to a phone number resulted from a first interaction of a set of interactions. In general, another aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a rank score for an online content item, including for each call of a plurality of phone calls to the phone number, attributing the call to an online content interaction of a set of online content interactions; determining, using the rank score, whether to provide the online content item to a client device; and providing the online content item to the client device upon determining to do so using the rank score.

Abstract:

A vehicle computing system validates location data received from a Global Navigation Satellite System receiver with other sensor data. In one embodiment, the system calculates velocities with the location data and the other sensor data. The system generates a probabilistic model for velocity with a velocity calculated with location data and variance associated with the location data. The system determines a confidence score by applying the probabilistic model to one or more of the velocities calculated with other sensor data. In another embodiment, the system implements a machine learning model that considers features extracted from the sensor data. The system generates a feature vector for the location data and determines a confidence score for the location data by applying the machine learning model to the feature vector. Based on the confidence score, the system can validate the location data. The validated location data is useful for navigation and map updates.

Abstract:

In one embodiment, a method includes receiving from a client computing device a request to upload a multimedia file from the client computing device to a service. The method includes identifying transcoding servers configured to receive and transcode multimedia files from client computing devices and store the transcoded multimedia files. The method includes sending a reply to the client computing device that includes job configuration information that includes an access token authorizing the client computing device to access the transcoding servers. The information specifies upload policies that include failover instructions for if a failure occurs during an upload from the client computing device to a first of the transcoding servers. The failover instructions include sending the access token to the first of the transcoding servers to resume the upload or sending the access token to a second of the transcoding servers to restart the upload.
