  • 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.

  • Patent number: 9586374
    Abstract: Described are methods of making a paint roller using thermoplastic strip material, adhesive and a composite cover material. The materials can be assembled in a continuous manufacturing process by helically winding a strip comprising polypropylene around a mandrel so as to form a helically wound strip, advancing the wound strip along the mandrel, applying a molten layer of adhesive comprising polypropylene onto the outer surface of the wound strip, wrapping a strip of composite cover material about the wound strip and over the layer of adhesive, and allowing the adhesive to cool, thereby laminating the composite cover material with the outer surface of the wound strip.

  • Patent number: RE46498
    Abstract: Body bias can be applied to optimize performance in a non-volatile storage system. Body bias can be set in an adaptive manner to reduce an error count of an error correcting and/or detecting code when reading data from non-volatile storage elements. Also, a body bias level can be increased or decreased as a number of programming cycles increases. Also, body bias levels can be set and applied separately for a chip, plane, block and/or page. A body bias can be applied to a first set of NAND strings for which operations are being performed by controlling a first voltage provided to a source side of the first set of NAND strings and a second voltage provided to a p-well. A source side of a second set of NAND strings for which operations are not being performed is floated or receives a fixed voltage.
