Publication number: 20160049807Abstract: A power management unit accurately measures and controls charging current. The power management unit may be implemented more efficiently than prior designs, leading to cost savings in the implementation of the power management unit as well as in the implementation of the device that incorporates the power management unit. The power management unit incorporates a model of an external charge control device (e.g., a transistor) and uses that model in a way that allows the power management unit to eliminate external device pins and other circuitry.Type: ApplicationFiled: October 29, 2015Publication date: February 18, 2016Inventors: Kerry Thompson, John McNitt, Mark David Rutherford

Publication number: 20050024125Abstract: The highly efficient, high current drive, multi-phase voltage multiplier reduces the inefficiency due to the active level overlapping portion of the clock at high frequencies, reduces the inefficiency due to extremely large drive currents on the inverters supplying current to the multiplying capacitors C1(*) and C2(*), and increases the efficiency of the multiplier by allowing M-1 phases to charge the output at any given time and providing more time given to each capacitor to fully charge and discharge. The ripple on the output is much smaller than in a single dual phase multiplier. This multi-phase voltage multiplier supplies very large current to the load while remaining very efficient.Type: ApplicationFiled: August 1, 2003Publication date: February 3, 2005Inventors: John McNitt, Russell Radke

Publication number: 20050024063Abstract: A method and apparatus are provided for measuring high speed glitch energy between first and second. The method and apparatus induce a change in charge on the first node from a first charge level to a second charge level with glitch energy supplied by the second node. An amount of charge is then supplied to the first node to restore the charge on the first node from the second charge level toward the first charge level. A representation of the amount of charge supplied to the first node is measured.Type: ApplicationFiled: July 31, 2003Publication date: February 3, 2005Applicant: LSI Logic CorporationInventors: John McNitt, Scott Savage

Patent number: 6567536Abstract: An analysis system and method for providing athletic training and instruction by sensing different types of information, such as video, positional information, weight transfer information etc and synchronizing the information. The synchronized information is replayed for the user in a manner that enables simultaneous viewing of an athletic motion along with calculations and presentation of analysis information related to the athletic motion.Type: GrantFiled: February 16, 2001Date of Patent: May 20, 2003Assignee: Golftec Enterprises LLCInventors: Michael John McNitt, Jeffrey Jack Parks, David Arthur Erb

Patent number: 6537076Abstract: An analysis system and method for providing athletic training and instruction by sensing different types of information, such as video, positional information, weight transfer information during a training session and storing the information to a lesson file. The method and system displays video information simultaneously with positional measurement information related to that is synchronized with the video information. Additionally, the displays are controlled using a single control element, or group of control elements. Moreover, the fact as to whether the displayed information is synchronized is automatically detected so as to link corresponding control elements together.Type: GrantFiled: February 16, 2001Date of Patent: March 25, 2003Assignee: Golftec Enterprises LLCInventors: Michael John McNitt, Jeffrey Jack Parks

Publication number: 20020115047Abstract: An analysis system and method for providing athletic training and instruction by sensing different types of information, such as video, positional information, weight transfer information during a training session and storing the information to a lesson file. The method and system marks portions of sensed information contemporaneously during the training session. Contemporaneous marking allows for saving of only pertinent information to lesson file without the need to review an entire lesson to generate the lesson file.Type: ApplicationFiled: February 16, 2001Publication date: August 22, 2002Applicant: GolfTEC, Inc.Inventors: Michael John McNitt, Jeffrey Jack Parks

Patent number: 6424200Abstract: A termination impedance in a semiconductor circuit is trimmed to fall within a desired range by a trimming circuit such that the amount of variation in the termination impedance is less than the variation in the sheet rho (resistivity) of the semiconductor. An external reference resistor causes a reference current to flow in multiple branches of a current mirror circuit. One branch of the current mirror circuit has a resistance less than the reference resistor, another has a resistance approximately equal to the reference resistor, and another has resistance greater than the reference resistor. Variation in the sheet rho results voltage drops across the resistor in variation in the resistor values. A logic circuit detects the variations, and encodes a control signal. The control signal is received by a variable termination circuit that switches parallel resistance branches in or out of the termination impedance circuit such that an effective termination impedance is selected based upon the control signal.Type: GrantFiled: June 12, 2000Date of Patent: July 23, 2002Assignee: LSI Logic CorporationInventors: John McNitt, Brett Hardy
