Abstract: The present invention is intended for use with a motor vehicle having at least one fluid-pressurized height adjusting member having first and second separable components. Apparatus constructed in accordance with the invention includes an integrated vehicle ride height system control system. The control system includes an electronic output drive signal circuit and input signal interpretation circuit to electronically interface with at least one position sensor. The position sensor provides output signals related to extent of separation of said first and second separable components of the fluid pressurized height adjusting member.

Abstract: A motor control system employed in a mechanism including displacers driven by motors, for example, a vehicle seat control system, includes motor operation parameter detection or simulation as inputs to adaptive algorithms to simplify the control system. The adaptive algorithms compensate for the interference with detection of generated or sensed pulses in previous pulse counting implementations. The seat control permits additional functions to be performed without numerous sensors, power controls and robust demands required in previous systems for controlling motors.

Abstract: A controller for energizing a power-operable element, such as a sunroof, window, door, vehicle seat, a component of a major appliance or of a machine or of a conveyor system. The disclosed controller senses both hard and soft obstructions and de-activates or otherwise alters operation of a motor that drives the element when an obstruction is detected. The controller can also be used to actuate a brake. The controller senses obstructions during start-up of the motor and regulates the speed of the power-operable element by pulse width modulating motor energization signals.

Abstract: An electronic control system is an in-line module for addition to or partial replacement of automotive vehicle seat control systems for providing massage and improved features of functional control, especially human lumbar massage and diagnostics. The module provides the following improved functions and features: an enhanced driver for automatic lumbar massage, or user taught lumbar massage cycle, and a transparency simulator for low power standby operation, motor stall protection, open motor circuit detection, short motor circuit protection, motor low current protection, motor over current protection, seat position sensor malfunction detection, electrical motor noise attenuation, electrical noise filtering, and also other options. These improvements do not require alternative wiring harness changes and do not affect existing operations of a memory or non-memory seat control mechanism.

Abstract: A controller for energizing a power window or panel such as a power sunroof. The disclosed controller senses both hard and soft obstructions and deactivates a motor that moves the sunroof when an obstruction is detected. The controller also senses obstructions during start-up of the motor and regulates the speed of the window or panel by pulse width modulating motor energization signals.
