  • Patent number: 11942906
    Abstract: The present invention provides a transmitter including a mixer, a harmonic impedance adjustment circuit and an amplifier. The mixer is configured to mix a first baseband signal with a first oscillation signal to generate a first mixed signal to a first node, and to mix a second baseband signal with a second oscillation signal to generate a second mixed signal to a second node. The harmonic impedance adjustment circuit is coupled between the first node and the second node, and is configured to reduce harmonic components of the first mixed signal and the second mixed signal to generate an adjusted first mixed signal and an adjusted second mixed signal. The amplifier is coupled to the harmonic impedance adjustment circuit, and is configured to generate an amplified signal according to the adjusted first mixed signal and the adjusted second mixed signal.

  • Publication number: 20230346178
    Abstract: An anti-collision mechanism comprises a body, a collision baffle, a magnetic element, and a magnetic field sensor, and the anti-collision mechanism is configured to be applicable to a sweeping robot. The magnetic field sensor is arranged at a distance from the magnetic element, the magnetic field sensor is configured to detect a change in the magnetic field intensity caused by a change in the distance between the magnetic field sensor and the magnetic element. When the collision occurs, the magnetic element is closer to the magnetic field sensor to make the magnetic field intensity change, thus generating signals to stop or turn the sweeping robot, which can realize the obstacle avoidance of the sweeping robot and enhance the service life. The sweeping robot is also provided.

  • Patent number: 8302113
    Abstract: A disk drive mechanism includes a bracket and a tray slidably received in the bracket. The bracket includes a bottom wall, two sidewalls protruding from the bottom wall, two guiding rails fixed to the sidewalls respectively, and two sliding rails slidably coupled to the guiding rails respectively. The bottom wall and the sidewalls cooperatively define an entrance. Each guiding rail includes an end maintaining a distance from the entrance. The tray is slidably coupled to the sliding rails and is capable of being inserted into and ejected out of the bracket from the entrance via the sliding rails. A supporting member is arranged between the end of each guiding rail and the entrance. The supporting member is used to support the sliding rails in a direction perpendicular to the direction of the tray inserted into the bracket. An electronic device using the disk drive mechanism is also provided.
