Abstract: A method, system and apparatus for carrying a user including a board for supporting the user, a plurality of ground-contacting members coupled with the board, a motorized drive assembly coupled with the ground-contacting members and one or more sensors coupled with the drive assembly. In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors.

In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. As a result, the system is able to maintain a desired velocity when ascending, descending or traversing uneven ground without the need for excessive and sometimes impossible tilting of the board.

Abstract: Intelligent servomotor controller, including integrated servomotor controller having motor with rotor in first housing; rotor position encoder producing measured position of rotor; microprocessor within second housing mating to first housing, electrically connected to rotor position encoder, serial communications port connecting to another integrated servomotor controller communicating desired rotor position command using serial digital data, microprocessor having software receiving desired position commands through communications port, computing error between desired position command and encoder-transmitted measured rotor reducing error signals to zero. Microprocessor is a position based servo system within second housing and rotor within first housing to desired position defined by communication with another integrated servo element. Microprocessor produces actuation signal to direct PID filter connected to microprocessor, PID filter providing drive amplifier servo control of supplying current to the motor.

Abstract: A panel is provided, which is a building block, for a trade show booth. Each panel includes a support structure having rails secured to the edges. Each rail has magnetic fastening strips and metal guidance blades disposed in the lengthwise extending slots, which engage with similar structures in other panels or other rails. Separate rails have mutually engageable lobes and lobe-engaging openings to allow a plurality of panels to be placed in any trade show booth configuration.

Abstract: An integrated motion control device having a controller mated to a motor body with a set of rigid, electrically conductive signal pins. The motor is direct-current and preferably brushless, and has Hall sensors within the motor body and an encoder at a back end for precisely determining rotor position. Signals from the Hall sensors and encoder are fed to a microprocessor contained in the controller and including a PID filter for servo control of the motor. The controller contains an amplifier for driving the motor and a power supply for providing appropriate levels of DC power to various elements of the controller and motor. All electrical signals between the motor and controller are transmitted via the pins, eliminating wiring harnesses of the prior art and related signal noise and wiring problems. The motor body and controller are affixed with a few screws, allowing the controller to be removed from the motor while the motor remains connected to an application.
