  • Patent number: 9011260
    Abstract: A device and a method for automatic swing control are disclosed. The device and method are used for the automatic swing control of an overhang. The device for automatic swing control comprises an actuator and a movable block. The movable block comprises a hanger and an angle sensing device. The hanger is pivotably mounted on the lower end of the movable block and is used to suspend the overhang. The angle sensing device is electrically connected to the actuator, and used to sense the movement parameters of the hanger, and starts the selective rotation of the actuator when the swing angle is less than a preset value, so that when the hanger is at its predicted highest swing position, the movable block moves toward the direction where the hanger is about to move after the hanger passes its actual highest swing position to drag the overhang to swing.

  • Patent number: 8491402
    Abstract: A swing mechanism for an infant and child swing includes a swing arm, a swing angle adjustment assembly and a PWM motor driving unit. The swing arm is driven by a motor for swinging forth and back in a first direction and a second direction. The swing angle adjustment assembly includes a knob, a connecting arm and a sensor, wherein the knob is associated with the sensor by the connecting arm thereby moving the sensor to a reference point at a swing height of the infant and child swing by turning the knob. The PWM motor driving unit inputs an adjustable voltage to the motor for driving the swing arm, and interrupting the adjustable voltage thereafter when the swing arm arrived the reference point in the first direction. A method for controlling the infant and child swing uses the swing mechanism as described above.

  • Publication number: 20130184088
    Abstract: An infant care apparatus includes a base, a reciprocating vertical motion mechanism, a vertical motion driving module, a reciprocating pendulum motion mechanism, and a pendulum motion driving module. The vertical motion driving module is kinematically connected to the reciprocating vertical motion mechanism so as to vertically move the reciprocating vertical motion mechanism in reciprocating vertical motion with respect to the base. The pendulum motion driving module is kinematically connected to the reciprocating pendulum motion mechanism so as to pendulum move the reciprocating pendulum motion mechanism in reciprocating pendulum motion with respect to the reciprocating vertical motion mechanism. An interaction between a reciprocating vertical motion of the reciprocating vertical motion mechanism and a reciprocating pendulum motion of the reciprocating pendulum motion mechanism forms a specific motion path.

  • Publication number: 20130102404
    Abstract: Various embodiments of the present invention are directed to a powered children's swing. In various embodiments, the swing includes a seat, swing frame, one or more swing arms, a first magnetic component, second magnetic component, swing motion sensor, and swing control circuit. The magnetic components are configured to generate a magnetic force that drives the seat along a swing path. The swing control circuit is configured to control the magnetic components based at least on input from the swing motion sensor and generate control signals causing the seat to swing with a substantially constant amplitude as specified by a user.

  • Patent number: 8419559
    Abstract: An infant swing includes a carrier, a first foot, at least one arm, a second foot, a pivotal positioning mechanism, a driving device, and a power supply device. The arm is connected to the first foot and the carrier. A second pivot base of the second foot is pivotally connected to a first pivot base of the first foot. The second foot is used for supporting the carrier above a supporting surface cooperatively with the first foot and the arm. The pivotal positioning mechanism is disposed between the first pivot base and the second pivot base. The pivotal positioning mechanism is used for constraining rotation of the second foot. The driving device is used for driving the arm. The power supply device is used for providing electric power to the driving device so as to make the carrier capable of swinging relative to the first foot.

  • Patent number: 8342977
    Abstract: The amplitude of a swing powered by an electric motor is controlled by detecting a peak voltage induced in the motor coil by the swing motion when the motor is not being powered and comparing the detected voltage with a one of a set of pre-measured reference values of peak voltages obtained at corresponding amplitude settings to provide a signal to a motor controller which adjusts the power supplied to the motor to bring the swing amplitude to. The motor controller supplies a PWM signal voltage to power the motor and adjusts the voltage on-time to bring or restore the swing to the selected amplitude.
