Abstract: An accelerometer is limited to a very small displacement range, and within that range, is useful for detecting motion and change of rate of motion by optical, magnetic, or electrical means. A unique spring suspends a planar mass that is very sensitive to motion of an object in which the accelerometer is held. In one embodiment, an optical detector detects the motion of the mass by the intensity of reflected radiation. In another embodiment, a Hall-effect sensor detects the motion of the mass by a current generated by the motion of the mass in an electric field. The accelerometer may be used in a variety of automotive, appliance, and industrial applications.

Abstract: An data interface module is provided for allowing a user to remotely modify a predetermined number of operating parameters of a motor driven by a motor control and for displaying the same. The interface module includes a micro-controller interconnected to a communications network and a visual display structure. The visual display structure has a first screen which displays a scrollable list of the operating parameters and a second screen which displays a data value for a user selected one of the operating parameters. A user may modify the user selected operating parameter when the second screen is displayed.

Abstract: An interface module is provided for allowing a user to remotely set the operating parameters of a motor driven by a motor control. The interface module includes a micro-controller having a plurality of input devices interconnected thereto. Each input device provides a control signal to the micro-controller which, in turn, generates an instruction signal in response thereto. A communications link transmits the instruction signal from the micro-controller to the motor control over a network.
