Patent number: 11007926Abstract: An apparatus and method for controlling a headlight. The apparatus has a first light sensor at a first portion of a vehicle and a system controller. The system controller is operatively coupled to the first light sensor and configured to adjust a state of the headlight based at least in part on a first light detection notification that indicates whether light has been received by the first light sensor and a first identifying signal notification that indicates whether received light is modulated and if modulated the presence of one or more identifying signals.Type: GrantFiled: March 16, 2020Date of Patent: May 18, 2021Assignee: Arm LimitedInventors: George Christopher Smart, Andrew Robert Gardner

Publication number: 20190001099Abstract: There is provided a catheter assembly wherein at least one of the arterial lumen and the venous lumen are radially displaceable in the transverse plane relative to the longitudinal axis of the catheter body between an insertion position and a drawing position. The maximum radial displacement in the transverse plane, between the radially displaceable arterial and/or venous lumen and the longitudinal axis of the catheter body is greater in the drawing position than in the insertion position. There is also provided a method of inserting and removing the catheter assembly into or from a blood vessel, and a method of treating blood using the catheter assembly.Type: ApplicationFiled: July 28, 2016Publication date: January 3, 2019Inventor: Christopher Smart

Patent number: 8020537Abstract: A fuel vaporizer system for an internal combustion engine including a first closed chamber defining a first volume, the first closed chamber having a heat transfer surface; a second closed chamber at least partially surrounding the first closed chamber and defining a second volume; and a third closed chamber at least partially surrounding the second closed chamber and defining a third volume. A liquid fuel supply system including a liquid fuel supply line emits fuel into the first volume in an expanding pattern of liquid fuel spray from at least one orifice. A thermal fluid system from said engine is configured to circulate fluid, which may be engine coolant, through the second volume and transfer heat from the fluid through the first closed chamber and vaporize said liquid fuel. An exhaust system from said engine is configured to circulate exhaust through the third volume and transfer heat from the exhaust through the second closed chamber and heat said fluid.Type: GrantFiled: April 29, 2011Date of Patent: September 20, 2011Assignee: Advanced Mileage Technologies, LLCInventor: Christopher Smart

Patent number: 7980230Abstract: A fuel vaporizer for an internal combustion engine having a closed pressure chamber defining a volume, to be heated, and a liquid fuel supply system disposed to emit a liquid fuel spray. The closed pressure chamber may be constructed and arranged relative to the heat-transfer surface to establish between the at least one outlet and the heat-transfer surface a mixing domain in which the fuel spray, as it progresses through the volume from the outlet, is substantially heated and vaporized by mixing with re-circulated, heated fuel vapor that previously has moved over and received heat from the heat transfer surface. The fuel vaporizer may be associated with a vapor outflow passage through which pressurized vapor exits the closed pressure chamber for supply to said at least one combustion region. The heat-transfer surface may be arranged to be heated by engine coolant circulating around the exterior of the closed pressure chamber.Type: GrantFiled: June 1, 2010Date of Patent: July 19, 2011Assignee: Advanced Mileage Technologies, LLCInventor: Christopher Smart

Patent number: 6912918Abstract: The mass flow rate sensor includes a waveguide disposed in a flow passage having a bluff body facing in an upstream direction. Waves are pulsed along the waveguide for interaction with the fluid. A receiver is coupled to the waveguide to detect a propagated wave and provides a first output signal proportional to the transit time of the propagated wave for determining fluid density. The receiver also provides a second output signal proportional to the shedding frequency of vortices from the waveguide to determine velocity. An electronics module calculates mass flow rate from the velocity times density times area of the flow passage and a constant. In other forms, the velocity is ascertained by transmitting an ultrasonic beam through the shedding vortices to determine vortex frequency which is proportional to velocity.Type: GrantFiled: March 10, 2004Date of Patent: July 5, 2005Assignee: General Electric CompanyInventors: Lawrence C.
