  • Light emitting diode activation control
    Patent number: 10582598
    Abstract: A system and method may include receiving, at a first node of a circuit electrically coupled to a light emitting diode, a pulsed electrical signal that includes signal current pulses. The system and method may also include enabling discharging of a capacitor electrically coupled to the first node at an enable time that is during a particular time period between two particular signal current pulses of the pulsed electrical signal.
    Type: Grant
    Filed: November 2, 2017
    Date of Patent: March 3, 2020
    Assignee: KATERRA INC.
    Inventors: Bahman Sharifipour, Tony Fung, Ocean Wu, Marti Willemsen, Mark Thomas

  • Light emitting diode activation control
    Patent number: 10537005
    Abstract: A system and method may include receiving, at a first node of a circuit electrically coupled to a light emitting diode, a pulsed electrical signal that includes signal current pulses. The system and method may also include enabling discontinuous discharging of a capacitor electrically coupled to the first node during a particular time period between two particular signal current pulses of the pulsed electrical signal.
