  • Patent number: 10548088
    Abstract: This disclosure relates to dynamic baseband management for a wireless device. The wireless device may be an accessory device. The accessory device may determine whether it has a short-range wireless communication link with a companion device. The accessory device may determine one or more proximity metrics relating to the companion device. The accessory device may further determine one or more metrics associated with user settings, user activity and/or application activity at the wireless device. The wireless device may select a (e.g., full, limited, or off) baseband operating mode based on any or all of these considerations.

  • Patent number: 10531964
    Abstract: A pivoting wedge expandable spinal implant. An upper portion and a lower portion are pivotally connected together. The implant, in a collapsed position, is inserted into a disc space. A driving screw engages and applies a force to a pushing portion, driving the pushing portion toward the implant's distal end. The pushing portion engages and drives a wedge toward the implant's distal end. The wedge pivots upward against an inner surface of the lower portion. The wedge continues to pivot along an inner surface of the upper portion, translating the force to the upper portion, pivoting and expanding the upper portion to an expanded position.

  • Patent number: 10480537
    Abstract: An evacuator for supplying vacuum to a device in a boosted engine air system is disclosed. The evacuator defines a body comprising a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap located between an outlet end of the converging motive section and an inlet end of the diverging discharge section.

  • Patent number: 10443627
    Abstract: Venturi devices that create vacuum have a housing defining a motive passageway converging toward a suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is generally aligned with and spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap, and the suction passageway enters the suction chamber at a position that generates about a 180 degree change in the direction of suction flow from the suction passageway to the discharge passageway. The motive passageway may terminate in a spout protruding into the suction chamber disposed spaced apart from all one or more sidewalls of the suction chamber and may subdivide downstream of the single entrance into two or more subpassageways each leading to one of two or more motive exits.

  • Patent number: 10422351
    Abstract: Devices for producing vacuum using the Venturi effect are disclosed that have a motive passageway converging toward a suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway, all of which are in fluid communication with the suction chamber. The motive passageway has a single entrance, and subdivides downstream thereof into a plurality of subpassageways, one each leading to one of the plurality of motive exits, which are spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap. The fletch having a plurality of ribs extending between an exterior surface of the generally conically-shaped main body thereof and an interior surface of the motive passageway is disposed in the motive passageway. The ribs divide the motive passageway into the plurality of sub-passageways, each converging fluid flow over the exterior surface thereof toward one of the plurality of motive exits.

  • Publication number: 20190201209
    Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

  • Patent number: 10324213
    Abstract: A capacitive proximity sensor may include a proximity sensing capacitor to provide a voltage output based on a voltage input, the capacitor including a ground plane and an electrode loop capacitively coupled to the ground plane. The proximity sensor may include a processor to detect an object proximity based on a change in the voltage output. This proximity sensor provides automated detection of a person, and thereby reduces the need for a vehicle occupant or child caregiver to activate a sensor by pressing a button. The use of a capacitance-based proximity sensor reduces issues associated with fabric, clothing, or other materials separating the proximity sensor from a person.

  • Patent number: 10316864
    Abstract: Devices for producing vacuum using the Venturi effect have a housing defining a suction chamber, a motive passageway converging toward the suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway in fluid communication with the suction chamber. A solenoid valve is positioned in the suction passageway and has an elongate sealing member received inside a coil, a first seal seat at a first end of the coil, and a second seal seat at the second end of the coil. The elongate sealing member is translatable within the coil between the first seal seat and the second seal seat, which define an open position and a closed position. Within the suction chamber, a motive exit of the motive passageway is generally aligned with and spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap.
