Patent number: 7208928Abstract: A power converter for coupling an energy source to a load device comprising a selectively coupled output stage to deliver energy from an energy source to a load device, a controller coupled to the output stage, an output stage, a capacitive element coupled to the output terminals, a rectifying element, and a switch responsive to a control signal from the controller. The rectifying element and switch are coupled to the inductive and capacitive elements. The controller is responsive to input signals for generating the control signal to open the switch in a first state and close the switch in a second state. The input signals to the controller produce one or more output voltages across the output terminals, an input voltage across the input terminals, a selectable reference voltage and a feedback signal measured with respect to the inductive element.Type: GrantFiled: March 16, 2001Date of Patent: April 24, 2007Assignee: The Board of Trustrees of the University of IllinoisInventors: Dragan Danilo Nebrigic, Milan Marcel Jevtitch, Vladimir Gartstein, William Thomas Mllam, James Vig Sherrill, Nicholas Busko, Peter Hansen

Patent number: 6643151Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor and/or the load capacitor. Also, a three-state control scheme is used to charge the fly capacitor, wait for the output voltage to drop to a predetermined level, and discharge the fly capacitor. Furthermore, a multiple-output charge pump power converter provides multiple voltage levels for devices such as portable communication electronic devices.Type: GrantFiled: October 9, 2001Date of Patent: November 4, 2003Assignee: The Board of Trustees of the University of IllinoisInventors: Dragan Danilo Nebrigic, Milan Marcel Jevtitch, Vladimir Gartstein, William Thomas Milam, James Vig Sherrill, Nicholas Busko, Peter Hansen

Patent number: 6370046Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump that includes a flying ultra-capacitor CUF. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Further efficiency is achieved by controlling the charging and discharging of the flying ultra-capacitor CUF, both in rate of current change and in voltage ripple.Type: GrantFiled: August 31, 2000Date of Patent: April 9, 2002Assignee: The Board of Trustees of the University of IllinoisInventors: Dragan Danilo Nebrigic, Milan Marcel Jevtitch, Vladimir Gartstein, William Thomas Milam, James Vig Sherrill, Nicholas Busko, Peter Hansen

In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Also, the dynamic control accommodates the advantages of using ultra-capacitors in the charge pump. The power converter is capable of operating with a sub-one volt input voltage incorporating low-threshold, low on-resistance power MOSFET switches in the switch matrix of the charge pump.Type: GrantFiled: March 22, 2000Date of Patent: October 30, 2001Assignee: The Procter & Gamble CompanyInventors: Dragan Danilo Nebrigic, Milan Marcel Jevtitch, Vladimir Gartstein, William Thomas Milam, James Vig Sherrill, Nicholas Busko, Peter Hansen

Patent number: 5903319Abstract: A method and apparatus for the elimination of temporal and spacial distortions from interlaced video signals, particularly those that occur in signals associated with affine transformations. This elimination is particularly of value for signals that have been magnified so as to prevent the visual appearance of reverse movement of moving images. The removal of these distortions is achieved by sequentially inputting the images fields into three field buffers, updating the data in a rotary manner. This data is withdrawn from any two of the field buffers, while the third field buffer is being updated, and averaging the data from the two. When such averaged data is displayed, there is no apparent reverse direction motion to the image. The method and apparatus are applied to a system wherein there is affine transformation to achieve selected pan, tilt, rotation and magnification of images during the correction of distorted images received from a wide angle lens.Type: GrantFiled: January 17, 1995Date of Patent: May 11, 1999Assignee: Interactive Pictures CorporationInventors: Nicholas Busko, H.

Patent number: 5877801Abstract: A system for achieving perspective-corrected views at a location removed from the site of the creation of a distorted wide angle image without the transmission of control signals to the site of image creation. Angles of tilt, pan and rotation, as well as degrees of magnification, are achieved without the use of mechanical devices by using transform algorithms. The system provides for the transmission of signals related to an uncorrected image from a site where this distorted image is created, with the transmitted signals being received at one or more processing sites for creating the perspectively-corrected views. Transmission can be via telephone lines, with the system including signal compression and decompression units. Wireless transmission is also utilized where desired.Type: GrantFiled: June 5, 1997Date of Patent: March 2, 1999Assignee: Interactive Pictures CorporationInventors: H. Lee Martin, Daniel P.
