Publication number: 20250243875Abstract: A controlled area progression diffuser for a compressor may be defined by a bearing diffuser face of a bearing housing and a compressor diffuser face of a compressor housing that are spaced apart by a diffuser width, and airflow from a compressor wheel enters the controlled area progression diffuser through a diffuser inlet, flows between the diffuser faces, and flows out of a diffuser outlet to a volute. The diffuser faces may be shaped so that the diffuser width decreases as the controlled area progression diffuser extends radially away from the compressor wheel toward the volute so that an annulus area of the controlled area progression diffuser does not increase linearly for at least a portion of a radial length of the controlled area progression diffuser.Type: ApplicationFiled: April 16, 2025Publication date: July 31, 2025Applicant: BorgWarner Inc.Inventors: Robert Dirk Lotz, Robert Malcolm Wallace

Publication number: 20230349385Abstract: A rotating machine for delivering a working fluid to a system includes a compressor housing defining a compressor housing interior and partially defining a flow path. The rotating machine also includes a shaft and a compressor wheel disposed in the compressor housing interior. The rotating machine additionally includes a backplate coupled to the compressor housing and further defining the flow path. The backplate and the compressor housing are configured to direct working fluid from the compressor housing interior through the flow path. The backplate defines a working fluid connection adjacent the compressor wheel and/or the flow path such that the working fluid connection is fluidly coupled to the flow path and such that the compressor wheel delivers working fluid from the compressor housing interior and the working fluid connection to the flow path.Type: ApplicationFiled: April 21, 2023Publication date: November 2, 2023Inventors: John Robert ZAGONE, Robert Malcolm WALLACE, Kevin John FOGARTY, Samuel Whitney WELDON

Patent number: 11173073Abstract: Methods and apparatus are disclosed for monitoring incontinence events using inexpensive sensors coupled to an incontinence brief worn by a patient. In some examples of the disclosed technology, a radio frequency identification (RFID) tag is queried to return a sensor value indicating a level of moisture in an incontinence brief. A mobile device carried by a patient caregiver analyzes the sensor value and provides a display indicating a course of action to take, for example, whether to change the patient's incontinence brief.Type: GrantFiled: May 20, 2016Date of Patent: November 16, 2021Assignee: MacNaughton Living Trust utd Dec. 30, 2002Inventors: Carolyn Reeder MacNaughton, Robert Malcolm David MacNaughton

Patent number: 11104214Abstract: A roll tarp system for a truck or trailer having a container with a rear door. The roll tarp system includes a roll tarp mounted to an axle assembly and a cable coupler assembly coupled to the axle assembly. A flexible cable connects the cable coupler assembly to a rear arm which is pivotally attached to the rear door. The cable coupler assembly includes first and second hinge members and is rotatably coupled to the axle assembly to permit unrolling and rolling up of the tarp and to permit opening of the rear door in a sideways or upward direction. The cable coupler assembly may include one or more apertures to permit access to a manual drive shaft which passes through the cable coupler assembly.Type: GrantFiled: January 25, 2018Date of Patent: August 31, 2021Assignee: Roll Rite LLCInventors: Stephen Hunter, Douglas Piccard, Robert Malcolm, James Pinon

Patent number: 10947931Abstract: A product may include a bearing housing in which a shaft may be supported by a bearing so that it may rotate. A compressor wheel may be disposed on the shaft. A compressor cover may be connected with the bearing housing, which may form a compressor body and may define a chamber within which the compressor wheel may rotate. A diffuser may extend radially outward from the chamber and may receive gas from the compressor wheel. An inlet may be provided to the compressor body, which may receive a supply of exhaust gas. An EGR distribution cavity may be defined within the compressor body and may extend around the shaft. An EGR inlet channel may extend into the bearing housing from the inlet to the EGR distribution cavity. An EGR passage may extend from the EGR distribution cavity to the diffuser.Type: GrantFiled: October 12, 2018Date of Patent: March 16, 2021Assignee: BorgWarner Inc.Inventors: Joseph Powell McHenry, Gordon Clark Jenks, Robert Malcolm Wallace

Patent number: 10292624Abstract: A method and system for generating a three-dimensional scan of an object using a handheld scanner is disclosed. The method involves obtaining images of the object from a successive plurality of handheld scanner positions with respect to the object, and processing the images to generate a respective 3D frame for each of the plurality of handheld scanner positions. Each 3D frame includes data representing locations of a plurality of 3D points on a surface of the object. The method further involves comparing each successive 3D frame with at least one preceding 3D frame, determining whether a result of the comparison meets a correspondence criterion associated with generation of a 3D representation of the surface of the object, and initiating a recovery process when the correspondence criterion is not met.Type: GrantFiled: January 19, 2015Date of Patent: May 21, 2019Assignee: Vorum Research CorporationInventors: Robert Malcolm Sabiston, Jeffrey David Chang, Carl Saunders
