  • Patent number: 12176644
    Abstract: A connector assembly for coupling with one or more electrodes includes one or more cables with wires. A plug is electrically coupled with an end or ends of the cables. An electrode connector structure is electrically coupled with the cables and includes a body that is configured for forming an internal space. A cantilevered first arm has an end that cantilevers toward the internal space. The cantilevered first arm has a rest position and a flexed position. A stationary second arm and arm end extend into the internal space opposite the first arm. At least one of the ends of the cantilevered first arm and stationary second arm include an electrical contact. In the rest position, the end of the cantilevered first arm is positioned opposite the stationary second arm a first distance. In the flexed position, the cantilevered arm, moves away from the stationary second arm to separate the ends to a greater distance to receive the electrode and returns to the rest position to grip the electrode.

  • Patent number: 12068202
    Abstract: This application provides an integrated circuit device and a preparation method thereof, and relates to the field of semiconductor technologies. An isolation section for suppressing a leakage current path of two adjacent transistors may be formed by using a simple process. The integrated circuit device includes a substrate and a fin protruding from the substrate. The integrated circuit device further includes two adjacent transistors. The two adjacent transistors use two spaced segments on the fin as respective channels of the two adjacent transistors. A part that is of the fin and that is located between the two spaced segments is processed to obtain an isolation section. The isolation section is used to suppress current transfer between the two channels of the two adjacent transistors.

  • Patent number: 9801516
    Abstract: A surface cleaning appliance having a cleaner head that includes an agitator and a motor for driving the agitator. The appliance includes a switch coupling the motor to a supply voltage, a voltage sensor for measuring the magnitude of the supply voltage, a current sensor for measuring the magnitude of current through the motor, and a controller configured to output a PWM signal for controlling the switch. The controller then adjusts the duty cycle of the PWM signal in response to changes in the supply voltage and in response to changes in the current through the motor.

  • Patent number: 9438150
    Abstract: A method of controlling a brushless permanent-magnet motor. The method includes commutating a winding of the motor at times relative to zero-crossings of back EMF in the winding. Commutation is then advanced when the motor operates over a first speed range, and commutation is retarded when the motor operates over a second speed range higher than that of the first speed range.

  • Patent number: 9407085
    Abstract: A controller for a brushless motor that is configured to operate in normal mode or under-voltage mode. When operating in normal mode, the controller generates control signals for exciting a winding of the motor, monitors the magnitude of an input voltage, and switches to under-voltage mode in the event that the input voltage drops below an under-voltage threshold. When operating in under-voltage mode, the controller suspends excitation of the winding, monitors the magnitude of the input voltage, monitors the magnitude of a supply voltage used to power the controller, switches to normal mode in the event that the input voltage exceeds a restart threshold, and resets itself in the event that the supply voltage drops below a brown-out threshold.

  • Patent number: 8836254
    Abstract: A method of controlling an electrical machine that includes selecting an edge of a rotor-position signal as a reference edge and commutating a phase winding of the electrical machine at times relative to the reference edge. The rotor-position signal has at least four edges per mechanical cycle, each of the edges being associated with a respective zero-crossing in back EMF or minimum in inductance of the phase winding. The angular position of at least one of the edges relative to its respective zero-crossing or minimum is different to that of the other edges. The reference edge is then selected from the edges such that the angular position of the reference edge relative to its respective zero-crossing or minimum is the same with each power on of the electrical machine. Additionally, a controller and control system that implement the method.
