Patent number: 12045420Abstract: A touch sensitive apparatus comprises a top plate configured such that light from the one or more light sources is transmitted within the top plate with total internal reflection; and a base plate within which, light is transmissible. The base plate comprises a plurality of base plate elements optically separated from each other. The top plate and the base plate are configured such that if an external body touches a first surface of the top plate, then light is coupled from a second surface of the top plate into an underlying base plate element for transmission within that base plate element. Each base plate element has one or more detectors for detecting light transmitted within that base plate element. A processor determines information from the detectors relating to touching of the first surface of the top plate. An associated method is also described.Type: GrantFiled: December 23, 2020Date of Patent: July 23, 2024Assignee: Uniphy LimitedInventor: David Lomas

Patent number: 11720210Abstract: An optical input device includes at least one optically clear plate having at least one light source positioned at a peripheral edge thereof and arranged and configured to transmit frequency modulated light into the optically clear plate along its planar length at an angle such that the modulated light is contained within the plate via total internal reflection thereof. At least one photodetector is configured to receive some or all of the modulated light. A least one input mechanism is embedded within the optically clear plate and is mechanically moveable relative thereto. A processing module receives signals from the photodetector and generates data representative of information to be displayed on a display screen. Both mechanical movement of the input mechanism relative to the optically clear plate and the application of pressure to the clear plate generate respective changes in the modulated light received by the photodetector.Type: GrantFiled: February 16, 2022Date of Patent: August 8, 2023Assignee: Uniphy LimitedInventor: David Lomas

Patent number: 10684727Abstract: A touch sensitive screen arrangement includes an optically dispersive base plate and structures for transmitting light onto the base plate in response to an external body touching the screen at a touch point such that the location of incident light on the surface of the base plate is representative of the relative position of the touch point on the screen. The base plate captures and disperses light that is incident on it. The decrease in incident light intensity with distance from the location of incidence on the base plate approximates a substantially exponential function. A sensor detects intensity of light at a respective edge of the base plate. The arrangement calculates the relative position of the touch point on the screen from the detected light intensity and the exponential function and generates a control signal representative of a control input derived from the position of the touch point.Type: GrantFiled: December 5, 2018Date of Patent: June 16, 2020Assignee: Uniphy LimitedInventors: David Dearn, David Lomas

Patent number: 10443000Abstract: This patent application discloses engineering design modifications to the VSS exit, stripper entrance and the primary cyclone diplegs that can significantly reduce the underflow of reactor riser products into the stripper and reactor vessel and thereby produce higher desired product selectivities, improved stripping efficiency and a stripper vent gas, that continuously flows through the reactor vessel, with a low coke forming potential due to its low concentration of ethylene and higher molecular weight material, that could, if desired, be recovered separately from the primary riser products.Type: GrantFiled: June 5, 2017Date of Patent: October 15, 2019Assignee: Marathon Petroleum Company LPInventor: David Lomas

Publication number: 20090304112Abstract: An amplifier (10) comprises a digitally clocked automatic gain control loop (11, 12, 13, 14). A Pseudo random clock generator (14) generates the clock signals for the loop. The application introduces a scheme which reduces sidebands caused by digital gain control loops. The effect of gain control on a system can be seen as amplitude modulation on the signal whose amplitude is controlled. This amplitude modulation causes the same sidebands that are commonly seen with AM modulation. This invention introduces a novel method that alleviates AM sidebands for a digitally controlled gain control loop.Type: ApplicationFiled: March 12, 2007Publication date: December 10, 2009Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: David Lomas, Stephan Ahles
