The compensator line is operated at a second voltage while the wordline is at the first voltage; with the second voltage being greater than the first voltage. The wordline is operated at a third voltage while the access transistors are in an ON state, and the compensator line is operated at a fourth voltage while the wordline is at the third voltage. The third voltage may or may not be greater than the fourth voltage.

  • Publication number: 20180310773
    Abstract: A method for operating an automated food making apparatus having a motor, actuator arm, and an apparatus. The apparatus may be a paddle with flexible fins. The method rotates the paddle with a pin-shaft mechanism to dispense an ingredient placed in a canister, controls the motor automatically based on weight sensor readings, and locates a position of the actuator arm with position sensors. The same motor dispenses ingredients from a plurality of canisters. The method may have a plurality of paddle rotation and weight measurement steps until a target weight is reached. The plurality of paddle rotation steps may be unidirectional or bidirectional paddle rotation. The paddle may be rotated according to one or more paddle rotation algorithms, an error recovery algorithm, or different algorithms based on the amounts of ingredients remaining in the canister. The paddle may be rocked until the target weight is achieved.

  • Patent number: 10062035
    Abstract: The present disclosure provides methods and systems for using variable length representations of machine learning statistics. A method may include storing an n-bit representation of a first statistic at a first n-bit storage cell. A first update to the first statistic may be received, and it may be determined that the first update causes a first loss of precision of the first statistic as stored in the first n-bit storage cell. Accordingly, an m-bit representation of the first statistic may be stored at a first m-bit storage cell based on the determination. The first m-bit storage cell may be associated with the first n-bit storage cell. As a result, upon receiving an instruction to use the first statistic in a calculation, a combination of the n-bit representation and the m-bit representation may be used to perform the calculation.

  • Publication number: 20180225439
    Abstract: Authenticating users comprises a computing device that receives a manual authentication input of a user and initiates a first user session between the user and the user computing device. The device communicates a request for a first user authorization data from an authentication technology associated with the one or more computing devices and receives the first user authentication data. The user or the device terminates the first user session and subsequently receives an input of the user to initiate a second user session. The device communicates a request for second user authentication data from the authentication technology and compares the first user authentication data and the second user authentication data. The device identifies a match of one or more features of the first user authentication data and one or more features of the second user authentication data and authorizes the user to conduct the second user session.

    Abstract: This document describes techniques (400, 500, 600) and apparatuses (100, 700) for implementing low-power near-field communication (NFC) authentication. These techniques (400, 500, 600) and apparatuses (100, 700) enable a computing device (102) to detect, in a low-power state, an NFC-enabled device (104) with which to authenticate via NFC. In some embodiments, various components of a computing device (102) in a sleep state are activated to perform authentication and/or an indication is provided to a user indicating an initiation of the authentication.
