Patent number: 9381451Abstract: A quiescent zone fluid filter. A reservoir communicates via upstream and downstream communication ports with a fluid flow tube. At the upstream communication port, liquid flowing in the fluid flow tube enters a quiescent zone of the reservoir, whereupon particles therein descend. The liquid then rejoins the fluid flow tube at the downstream communication port free of particles therein. The quiescent zone fluid filter is advantageously implemented within a fluid flow control valve, as for example at the valve barrel of a barrel valve.Type: GrantFiled: March 6, 2012Date of Patent: July 5, 2016Assignee: GM Global Technology Operations LLCInventors: Pablo Valencia, Jr., Brian K. Bartnick

Patent number: 9079507Abstract: A method of and device for determining driving range for a vehicle operating with a rechargeable energy storage supply. The method includes performing a calculation based on a limited number of input parameters, including a driving distance, average speed, location and time of day. Other determinations, such as the possibility of using a battery power-depleting climate control system, as well as battery capacity and climate data for various seasonal and location factors may also be used in the calculations.Type: GrantFiled: October 27, 2011Date of Patent: July 14, 2015Assignee: GM Global Technology Operations LLCInventors: Irvin T. Smith, Brian K. Bartnick, Larry D. Laws, George K. Perekattu

Patent number: 8919378Abstract: A compact four-way fluid flow control valve wherein an inlet port and three outlet ports are all disposed on the sidewall of a manifold. A valve core is rotatably disposed within the manifold, and has first and second core openings. Annular seals are disposed at blind portions of the sidewall of the valve core in non-circumscribing relation to the core openings and in abutting relation to the manifold. Rotation of the valve core with respect to the manifold provides selected fluid flow to any of the outlet ports, as well as a trickle flow at a selected outlet port and fluid mixing between selected outlet ports.Type: GrantFiled: April 4, 2012Date of Patent: December 30, 2014Assignee: GM Global Technology Operations LLCInventors: Brian K. Bartnick, Corry W Johnson

Patent number: 8584708Abstract: A single actuator multi-port flow control valve composed of a plurality of generally cylindrically shaped port bodies rotatably mounted within a valve body. The port bodies are serially driven by a single actuator via a drive link system composed of a drive pin on the inferior side wall of a serial superior port body selectively abutting, during rotation, a driven tab on the superior side wall of its serially inferior port body. The position of each port body is known to an electronic controller which selectively actuates the actuator to set each port body angular position.Type: GrantFiled: August 24, 2011Date of Patent: November 19, 2013Assignee: GM Global Technology Operations LLCInventors: Brian K.

Patent number: 8443491Abstract: An assist handle includes a hinge and a bar having a global axis. The bar is rotatable about the global axis between a first position and a second position. A spring biases the bar toward the second position. A sleeve is defined by either the bar or hinge, and is generally aligned with the global axis. A pin is operatively attached to the other of the bar or hinge and is partially disposed within the sleeve. The pin is configured to allow rotation between the hinge and the bar. The pin includes a wide portion and an undercut portion smaller than the wide portion. The undercut portion creates at least one clearance region between the pin and the sleeve.Type: GrantFiled: May 24, 2010Date of Patent: May 21, 2013Assignee: GM Global Technology Operations LLCInventor: Brian K.

Patent number: 8418828Abstract: Embodiments of an unpowered pedal assist device are provided for use in conjunction with a vehicular control pedal movable between a non-depressed position and a depressed position. In one embodiment, the unpowered pedal assist device includes a multi-bar linkage and at least one resilient element coupled to the multi-bar linkage. The multi-bar linkage is configured to be coupled to the vehicular control pedal and, when so coupled to move from a start position to a finish position as the vehicular control pedal moves from the non-depressed position to the depressed position. The at least one resilient element is configured to bias the multi-bar linkage: (i) toward the start position over an initial range of travel of the vehicular control pedal, and (ii) toward the finish position over a primary range of travel of the vehicular control pedal.Type: GrantFiled: April 20, 2010Date of Patent: April 16, 2013Assignee: GM Global Technology Operations LLCInventor: Brian K.
