Patent number: 10270347Abstract: A short-circuit protected power supply circuit includes a switching power supply and a short-circuit sense/protection circuit. The switching power supply includes a synchronous rectifier, an output inductor, and an output capacitor. The synchronous rectifier is responsive to a synchronous rectifier control signal to selectively switch between an ON state and an OFF state. The output inductor and output capacitor are electrically connected in series with each other and are electrically connected in parallel with the synchronous rectifier. An output node is located between the output inductor and output capacitor. The short-circuit sense/protection circuit is coupled to the output node and is configured, upon a voltage magnitude at the output node being less than a predetermined voltage magnitude, to cause the synchronous rectifier control signal to switch the synchronous rectifier to, or keep it in, the OFF state.Type: GrantFiled: August 18, 2017Date of Patent: April 23, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Joseph Marotta, Paul Schwerman, Serdar Tevfik Sozusen

Patent number: 9207758Abstract: Embodiments include systems and methods for assisting an operator (e.g., a pilot) of an apparatus (e.g., an aircraft) that includes a control compartment (e.g., a cockpit). The system includes a near-eye display and a processing subsystem. The near-eye display includes a transparent display panel and is adapted to be worn on a head of the operator. The processing subsystem is adapted to receive layout information defining a physical layout of one or more operational components located within the control compartment. The processing subsystem is further adapted to determine a location for a display indicator on the transparent display panel, where the location is determined to appear to the operator to be in proximity to an operational component. The processing subsystem is further adapted to generate a display signal to cause the near-eye display to display the display indicator in the location.Type: GrantFiled: May 30, 2008Date of Patent: December 8, 2015Assignee: Honeywell International Inc.Inventors: Andrei Cernasov, Robert Mead, Joseph Marotta

Patent number: 8325497Abstract: A power supply may comprise a pulse-width-modulation (PWM) controller; a synchronous rectifier having a forward metal oxide field effect transistor (MOSFET) and a catch MOSFET; a forward gate driver; a catch gate driver; and the PWM controller connected so that a low output of the PWM controller facilitates operation of the catch MOSFET and so that the low output precludes operation of the forward MOSFET. The power supply may include a self powered synchronous rectifier that may be constructed with delay times that are independent of lot-to-lot and temperature-related timing variations of MOSFETS.Type: GrantFiled: June 7, 2010Date of Patent: December 4, 2012Assignee: Honeywell International Inc.Inventors: Joseph Marotta, Xavier Enriquez, Stanislav Suchovsky, Steven Lawson

Patent number: 8058876Abstract: A battery health or prognosis system may employ a ferrite disc embedded in a printed wiring board (PWB) to perform both a battery current sensing role and a temperature sensing role. The ferrite disc may be surrounded with a coil that may be comprised of surface conductors and electrically conductive vias of the PWB. Excursions of coil current may be produced to generate observable hysterisis loops in the ferrite disc. The generated hysterisis loops may be compared to a temperature-dependent family of hysterisis loops for the magnetic material from which the ferrite disc is constructed. A processor mounted on the PWB may collect and process outputs from a Hall-effect sensor to develop both temperature and battery current information to produce a prognosis for the battery.Type: GrantFiled: April 24, 2008Date of Patent: November 15, 2011Assignee: Honeywell International, Inc.Inventors: Andrei Cernasov, Joseph Marotta, Fernando De La Vega

Publication number: 20060062291Abstract: Embodiments of the present invention provide a closed loop control system that is capable of handling a wide variety of loads. In some embodiments, the control system uses a pulse width modulated (PWM) signal to drive a plant. The PWM signal has a switching frequency. A feedback signal is measured from the plant and provided back to controller. The feedback signal may be converted into a digital feedback signal based on oversampling the feedback signal at a multiple, such as twice, of the switching frequency of the PWM signal. The digital feedback signal may then be filtered to reduce or remove any unwanted components. For example, the digital feedback signal may be passed through a notch filter that suppresses a range of frequencies centered around the switching frequency of the PWM signal. In addition, the digital feedback signal may be passed through a digital low pass filter. Based on the filtered digital feedback signal, the controller may then adjust the PWM signal delivered to the plant.Type: ApplicationFiled: September 20, 2004Publication date: March 23, 2006Inventors: Joseph Marotta, Donald Porawski
