Patent number: 11393616Abstract: A driver circuit is provided to connect a charged capacitor through a switch to the inductive windings of an electromagnet for a haptic feedback application. A feedback circuit provides an indication of the current supplied. When the current reaches a desired level, the current is cut off, rather than being controlled. The cutoff level can be slightly below the desired level to allow the desired level to be reached with overshoot. A diode is provided in parallel with the electromagnet winding when the current is shut off, providing a recirculation path that prevents the current from being discharged, thereby dissipating less energy than classical solutions.Type: GrantFiled: September 24, 2020Date of Patent: July 19, 2022Assignee: Logitech Europe S.A.Inventor: Maxim Vlasov

Patent number: 11355948Abstract: Embodiments describe a wireless charging system including an accessory device and a host device. The host device can include a housing having a charging surface and power transmitting circuitry coupled to a power source. The power transmitting circuitry can include an inductive transmitter coil configured to receive a first power and generate magnetic field, an amplifier coupled to the inductive transmitter coil and configured to output the first power to the inductive transmitter coil, an output sensor coupled to the inductive transmitter coil and configured to measure the first power to the inductive transmitter coil, and a power tracking controller coupled to the sensor probe. The power tracking controller can be configured to receive measurement of the first power, and generate a control signal based on the measured first power to modify an output impedance of the amplifier to output a second power different from the first power.Type: GrantFiled: June 28, 2019Date of Patent: June 7, 2022Assignee: Logitech Europe S.A.Inventors: Maxim Vlasov, Laurent Plancherel
