Patent number: 11963652Abstract: A handheld vacuum cleaner includes a dirt separator. The dirt separator includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes.Type: GrantFiled: July 27, 2018Date of Patent: April 23, 2024Assignee: Dyson Technology LimitedInventors: Charles Howard Percy-Raine, Andrew John Isaacs, Alexander Michael Campbell-Hill, Stephen Robert Dimbylow

Patent number: 10975855Abstract: A pump comprising a side wall closed at each end by an end wall forming a cavity for, in use, containing a fluid, one or more actuators each operatively associated with one or more of the end walls to cause an oscillatory motion of the associated end wall(s) whereby, in use, these axial oscillations of the end wall(s) drive substantially radial oscillations of the fluid pressure in the cavity, two or more apertures in the cavity, a valve disposed in at least one of the apertures, wherein the actuator(s) is arranged to be non-axisymmetric in use such that, in use, a pressure oscillation with at least one nodal diameter is generated within the cavity.Type: GrantFiled: February 3, 2012Date of Patent: April 13, 2021Assignee: THE TECHNOLOGY PARTNERSHIP PLC.Inventors: Andrew Robert Campbell, Justin Rorke Buckland

Patent number: 10087923Abstract: A fluid pump comprising one or two cavities which, in use, contains a fluid to be pumped, the chamber or chambers having a substantially cylindrical shape bounded by first and second end walls and a side wall; an actuator which, in use, causes oscillatory motion of the first end wall(s) in a direction substantially perpendicular to the plane of the first end wall(s); and whereby, in use, these axial oscillations of the end walls drive radial oscillations of the fluid pressure in the main cavity; and wherein an isolator forms at least a portion of the first end wall between the actuator and the side wall and includes conductive tracks, wherein electrical connection is made to the actuator via the conductive tracks included within the isolator.Type: GrantFiled: February 11, 2013Date of Patent: October 2, 2018Assignee: The Technology Partnership PLC.Inventors: Andrew Robert Campbell, Justin Rorke Buckland

Patent number: 9869659Abstract: An acoustic sensor includes a side wall, closed at each end by an end wall, to form a substantially cylindrical cavity, a transmitter and a receiver operatively associated with first and second respective end walls. Properties of the relative dimensions of the cavity are configured to create a desired oscillatory motion of the end walls, and oscillations of a fluid pressure in the cavity, to generate an electrical signal via the receiver to be output from the sensor. An array of acoustic sensors can be connected to allow calibration of one of the array of sensors.Type: GrantFiled: December 6, 2012Date of Patent: January 16, 2018Assignee: The Technology Partnership PLC.Inventors: Justin Rorke Buckland, Andrew Robert Campbell

Publication number: 20110304774Abstract: Embodiments are disclosed that relate to the automatic tagging of recorded content. For example, one disclosed embodiment provides a computing device comprising a processor and memory having instructions executable by the processor to receive input data comprising one or more of a depth data, video data, and directional audio data, identify a content-based input signal in the input data, and apply one or more filters to the input signal to determine whether the input signal comprises a recognized input. Further, if the input signal comprises a recognized input, then the instructions are executable to tag the input data with the contextual tag associated with the recognized input and record the contextual tag with the input data.Type: ApplicationFiled: June 11, 2010Publication date: December 15, 2011Applicant: MICROSOFT CORPORATIONInventors: Stephen Latta, Christopher Vuchetich, Matthew Eric Haigh, JR., Andrew Robert Campbell, Darren Bennett, Relja Markovic, Oscar Omar Garza Santos, Kevin Geisner, Kudo Tsunoda
