Publication number: 20240093686Abstract: Rotary positive displacement machines based on trochoidal geometry and including a helical rotor that undergoes planetary motion relative to a helical stator can be designed and configured so that the axial load or rotor pressure force is positive, negative, or neutral. In some embodiments, a change in axial load, caused by a change in differential pressure across the machine, can be used to trigger a change in a mechanical configuration of the machine.Type: ApplicationFiled: September 20, 2023Publication date: March 21, 2024Inventors: Greg John Montie, Peter Thomas Christopher Suke, Bryan Allen Callaway

Patent number: 11876721Abstract: The techniques described herein enable the use of a time factor for traffic management and routing. A system is configured to analyze traffic for a service over a period of time and identify (e.g., learn) traffic patterns that reflect a substantial effect on traffic during a particular real-world event. Using the traffic patterns identified via the analysis, the system can provide valuable time-based traffic information to service providers. A service provider can then create a predefined time-based profile that is used by a traffic manager to switch from a current traffic routing configuration to a different traffic routing configuration that better accommodates an expected traffic load for various endpoints. The predefined time-based profile specifies a scheduled time at which the switch is to occur, and this scheduled time can correspond to a start time for a real-world event that is known to cause an increase or decrease in traffic.Type: GrantFiled: April 9, 2021Date of Patent: January 16, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Matthew John McCreesh, Abhishek Agarwal, Allen Callaway, Rohin Koul

Patent number: 11815094Abstract: Rotary positive displacement machines based on trochoidal geometry that includes a helical rotor that undergoes planetary motion relative to a helical stator are described. The rotor can have a hypotrochoidal-based cross-sectional shape, with the corresponding stator cavity cross-sectional shape being the outer envelope of the rotor cross-sectional shape as it undergoes planetary motion, or the stator cavity can have an epitrochoidal-based cross-sectional shape with the corresponding rotor cross-sectional shape being the inner envelope of the stator cross-sectional shape as it undergoes planetary motion. Such machines can be configured so that the stator axis is spaced from the rotor axis, the rotor is configured to spin about its axis and the stator is configured to spin about its axis, and/or the rotor and the stator are held at a fixed eccentricity so that the rotor undergoes planetary motion relative to the stator, but does not orbit.Type: GrantFiled: March 10, 2021Date of Patent: November 14, 2023Assignee: Rotoliptic Technologies IncorporatedInventors: Greg John Montie, Peter Thomas Christopher Suke, Adrian James Corless, Bryan Allen Callaway

Publication number: 20230098259Abstract: Sealing in rotary positive displacement machines based on trochoidal geometry that comprise a helical rotor that undergoes planetary motion within a helical stator is described. Seals can be mounted on the rotor, the stator, or both. The rotor can have a hypotrochoidal cross-section, with the corresponding stator cavity profile being the outer envelope of the rotor as it undergoes planetary motion, or the stator cavity can have an epitrochoidal cross-section with the corresponding rotor profile being the inner envelope of the trochoid as it undergoes planetary motion. In some embodiments, the geometry is offset in a manner that provides advantages with respect to sealing in the rotary machine. In multi-stage embodiments, the rotor-stator geometry remains substantially constant or varies along the axis of the rotary machine.Type: ApplicationFiled: October 7, 2022Publication date: March 30, 2023Inventors: Greg John Montie, Bryan Allen Callaway

Patent number: 9546069Abstract: The claimed subject matter includes techniques for controlling lines. An example method includes receiving power at a motor to rotate a control surface and a line brace. The method also includes receiving programmed movements at a control circuit. The method further includes receiving a controlled force based on the programmed movements to arrange a skate in a predetermined position along a skate track in a skate surface. The method also includes rotating the control surface to cause a peg ramp on the control surface to move a peg in the skate towards a wedge fixed to a line. The method further includes causing the line to move to a new position along the direction of the skate track via a force of the peg against the wedge.Type: GrantFiled: April 9, 2015Date of Patent: January 17, 2017Assignee: Microsoft Technology Licensing, LLCInventor: Allen Callaway
