  • Publication number: 20210324863
    Abstract: A vacuum pump generally comprises a low pressure portion and a high pressure portion separated by a gas impermeable partition. Gas molecules exit the low pressure portion through an opening in the partition and passively impinge on a featureless rotatable surface in the high pressure portion. A drive rotates the rotatable surface with tangential velocity in the supersonic range at multiple times the most probable velocity of the impinging gas molecules. Impinging gas molecules are ejected outwardly from the periphery of the rotatable surface generating a substantial net outward flow of gas and reducing the pressure in the low pressure portion. The vacuum pump is effective to reduce the pressure in the low pressure portion to a target minimum pressure without using seals to prevent gas molecules from leaking back to the low pressure portion and without using blades or vanes to actively impact the gas molecules.

  • Patent number: 11087561
    Abstract: An enhanced multimodal interface and various enhanced tools are provided to enable a user to create 3-D augmented reality (AR) sketches using a mobile device. Mobile device can comprise a sketch generator component (SGC) that can integrate multiple sources of inputs with enhanced tools, comprising enhanced 3-D snapping and proxy creation tools. The inputs comprise touch screen data, motion data, and image data from a camera. SGC can provide the interface, which can support absolute and relative drawing. Via the interface, the user can select and use desired enhanced tools to create a 3-D AR sketch that augments visual content of a real-world environment captured by the camera with drawing content added by the user using the enhanced tools. SGC enables a user to create desired strokes, planar or curved surface proxies, snapping points, or other sketch features, wherein proxies can align with real-world surfaces.

  • Publication number: 20210127889
    Abstract: A reusable cartridge and method for forming a beverage using a beverage machine. The cartridge may include multiple openings, e.g., arranged to receive an inlet needle, through which liquid may be introduced into the cartridge. One or more of the openings may be closed to flow, e.g., by a plug that engages with a corresponding opening by a friction fit. A filter basket may be inserted or removed into the interior space through the opening and a cover may engage at top to seal the opening closed.

  • Publication number: 20210065128
    Abstract: A computer-implemented method for modeling candidate equity includes tracking, in a computer system, a plurality of candidates in a recruiting pipeline including a plurality of stages, with each of the plurality of candidates being in a stage of the pipeline for a position and being owned by one of a plurality of recruiters. For each candidate, the system calculates a placement likelihood corresponding to the likelihood that the candidate will be placed in the position and computing a candidate equity based on the placement likelihood and an expected placement value. The system then compensates each recruiter based on revenue recognition rules and on an amount of change in the candidate equity of the candidates owned by the recruiter over time.
