  • Patent number: 9591733
    Abstract: A drum assembly includes a drum, a stimulus processor assembly and a Tesla coil. The stimulus processor assembly receives a stimulus, generates an input signal, and converts the input signal to an output signal. The Tesla coil receives the output signal from the stimulus processor assembly. The Tesla coil emits an electrical discharge in response to the output signal. The electrical discharge occurs at least partially within the drum interior. The stimulus processor assembly uses a conversion algorithm to convert the input signal to an output signal. The Tesla coil can be positioned inside or outside of a drum interior of the drum. A discharge router can send the electrical discharge from the Tesla coil to the drum interior. The electrical discharge can have an intensity that is correlative to the decibel level of the stimulus. The stimulus can be generated by the drum or by a source remote from the drum.

    Abstract: Devices, systems, and methods are provided for providing physical feedback in a handheld electronic controller. In general, the devices, systems, and methods can allow a handheld controller in an electronic system to provide a shock force or impact force to a user of the controller. In one exemplary embodiment, the controller can be configured to provide the shock or impact force in correspondence with a virtual shock force or impact force in an entertainment system in communication with the controller being controlled by the user. The actual shock force or impact force can be directionally imparted to the controller such that the user feels the actual shock force or impact force in a same direction as the virtual shock force or impact force.

  • Patent number: 8830019
    Abstract: The structure includes cylindrical columnar and tubular bonded magnets. The columnar magnet has at least one pair of N and S poles that are alternately produced in the longitudinal direction. The tubular magnet surrounds the columnar magnet, and has at least one pair of N and S poles that are alternately produced in the longitudinal direction. Poles of the columnar and tubular magnets that are opposed to each other in the direction perpendicular to the axis of the columnar magnet as the propulsion force direction are of opposite magnetic polarity so that magnetic fields are produced in the direction perpendicular to the propulsion force direction. The surface magnetic flux density profile balance can be smoothed by adjusting higher and lower parts of the profiles of the columnar and tubular magnets.

  • Patent number: 8803646
    Abstract: A system and method for magnetic levitation with a tilted orientation. In one embodiment, a magnetic levitation base together with a magnetic levitation affecting element that is located to the side of the levitation base support the magnetic levitation of a spinning magnetic top in a tilted orientation. The tilt angle of the levitating magnetic top may be greater than the tilt angle of the levitation base. In one embodiment, the levitation affecting element may comprise one or more magnets similar to that of the levitation base. The mass of the top and the tilt of the levitation base that are required for magnetic levitation may be adjusted by adjusting the levitation affecting element (e.g. altering its position and/or the strength of its magnetic field.) The general direction of the tilt may be reversed by changing the magnetic north-south direction (e.g. turning over or reversing the electromagnetic current) of the levitation affecting element.
