Filed:

Apr 24, 2008

Appl. No.:

12/109190

Inventors:

Andrei Cernasov - Ringwood NJ, US
Joseph Marotta - Boonton NJ, US
Fernando De La Vega - Ridgefield Park NJ, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

G01N 27/416
G01N 27/82
G01R 11/02

US Classification:

324426, 324117 H, 324137

Abstract:

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.

International Classification:

H02M 3/335

US Classification:

363 18, 363 2112, 363 2114, 363 2118, 323282, 323283

Abstract:

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.

Appl. No.:

10/943976

Inventors:

Joseph Marotta - Boonton NJ, US
Donald Porawski - Cedar Grove NJ, US

International Classification:

H03K 7/08

US Classification:

375238000

Abstract:

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.

Appl. No.:

12/130045

Inventors:

Andrei Cernasov - Ringwood NJ, US
Robert Mead - Flemington NJ, US
Joseph Marotta - Boonton NJ, US

Assignee:

Honeywell International Inc., - Morristown NJ

International Classification:

G09B 9/08

US Classification:

434 30, 434 43

Abstract:

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.

Assignee:

HONEYWELL INTERNATIONAL INC. - MORRISTOWN NJ

International Classification:

H02H 7/09

US Classification:

361 33

Abstract:

A suppression circuit may be added to a motor driver circuit, which suppresses offset voltage and ringing in the output signal. The suppression circuit may include an RC circuit filter connected to a pin of a microchip providing a gating reference signal and a junction between high and low side MOSFETS connected to the microchip.

Assignee:

HONEYWELL INTERNATIONAL INC. - MORRIS PLAINS NJ

International Classification:

H02M 3/158

Abstract:

A power supply includes a DC-DC converter, a boost converter, an energy storage element; and a voltage clamping circuit. The DC-DC converter is connected to a power source with an output voltage in a first voltage range. The voltage clamper circuit is configured to discharge at least a portion of energy of the energy storage element and to produce current at a clamped output voltage range that is substantially equal to the first voltage range. The discharged energy provides hold-up time for the power supply.
