University of Toledo U.S. Patents

This collection includes United States patents for inventions by UT faculty, students and staff that list UT/MCO/MUO as the original assignee (owner). These patents include those assigned to the University of Toledo as well as to the Medical College of Ohio/Medical University of Ohio prior to the merger in 2006. Only granted patents, not patent applications, are included. Use the 'Search within this Series' box to search for keywords in the authors, titles, or abstracts of the patents.

A.C. Motor control circuit
A.C. Motor control circuit
A microprocessor based A.C. motor control circuit which can be used for both open and closed loop control includes a pair of RAMs for storing separate groups of synchronized digital waveforms for driving an A.C. motor. The microprocessor is used to calculate the group of digital waveforms required to maintain a controlled motor parameter at a desired value. One RAM has an output connected to supply the group of digital waveforms stored therein to a motor driver, while the second RAM is connected to receive a new group of digital waveforms which have just been calculated by the microprocessor. Once the new group of waveforms have been loaded into the second RAM, the microprocessor generates control signals to disconnect the output of the first RAM from the motor driver, and to connect the output of the second RAM to supply the newly calculated digital waveforms to the motor driver. The first RAM is then connected to receive the next group of digital waveforms to be calculated by the microprocessor.
AC to DC converter system with ripple feedback circuit
AC to DC converter system with ripple feedback circuit
A nonlinear ripple feedback circuit for use with a current-sourced rectifier system with an inductor input filter. The nonlinear ripple feedback circuit eliminates the oscillation of the rectifiers and improves the line-current waveform by sensing of and compensating for any amplitude of ripple appearing in the DC-side current. A sample of the rectified line voltage is multiplied by the product of a voltage feedback control signal times the ripple feedback signal ratio to form the input to the pulse-width modulator which produces the gating waveform for the converter of the rectifier system such that the oscillation and sensitivity of the converter system is reduced, and the AC line current waveform has low distortion, regardless of the DC-side ripple current levels.
AC to DC converter system with ripple feedback circuit
AC to DC converter system with ripple feedback circuit
A ripple feedback circuit for use with a current-sourced rectifier system with a resonant load balancing filter. The ripple feedback circuit eliminates the oscillation of the rectifiers and improves the line-current waveform by sensing the low frequency AC components of the output current and by combining such AC components with the control voltage at the input to the multiplier of the pulse width modulator of the rectifier system. A sample of the rectified line voltage is multiplied by the control voltage less ripple feedback to form the input to the pulse-width modulator which produces the gating waveform for the converter of the rectifier system.

Active suspension systems and components using piezoelectric sensing and actuation...
A lightweight, high performance, active suspension system utilizing piezoelectric regulated springs, and a method of manufacturing the suspension system, is described. Piezoelectric material is bonded to suspension springs, and excited appropriately to vary the stiffness of the suspension system. A method of controlling the stiffness of a spring includes piezoelectric material bonded to the spring, a sensor system for generating a signal proportional to the loading imposed on the spring, and controller for exciting the piezoelectric material in response to the signal. A control system for controlling the stiffness of a spring including embedding a plurality of piezoelectric particles within an electrically conductive matrix forming the body of the spring is also described.
