Patent number: 9755468Abstract: Systems and methods for generating currents in a plurality of CTS that may be independently controlled by a microprocessor. In some cases, a DC power source (such as a battery) is connected to each inverter. In other cases, a rechargeable DC power source (such as a capacitor) is connected to each inverter. Multiple controllable, turn-less structures may be provided in a suitable configuration with a single, main control processor or alternatively, with both a main control processor and several intermediate level command modules, each intermediate level command module coupled to a respective one of the inverters to control currents through each conductor of the respective inverter.Type: GrantFiled: February 18, 2016Date of Patent: September 5, 2017Inventor: Oved Zucker

Publication number: 20130313948Abstract: A topological change in motor philosophy based on a turn-less stator that is coupled to independent inverters with separate drives is presented herein. The turn-less stator has a multitude of parallel H bridges and an extremely low impedance. This combination of a turn-less stator and independent inverters is unlike conventional motor and actuator technology that requires multi-turn windings for impedance matching with conventional high impedance power systems.Type: ApplicationFiled: March 15, 2013Publication date: November 28, 2013Inventor: Oved Zucker

Publication number: 20110254607Abstract: Conductive segments (transmission line conductors) are positioned within a transmission line structure in order to generate multi-cycle microwave pulses. The conductor segments are switchably coupled to one or the other conductor of the transmission lines, inside the transmission line structure. Microwave pulses may be induced in the transmission line by closing the switches in a controlled manner to discharge successive segments, or successive groups of segments, into the transmission lines. The induced pulses travel uninterrupted along the transmission lines in a desired direction to the load. Efficiency of systems and energy delivered to the load in multi-section transmission lines is increased and/or maximized by adjusting the ratio of characteristic impedances associated with the transmission line conductor segments according to an optimum ratio.Type: ApplicationFiled: June 14, 2011Publication date: October 20, 2011Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Simon Y.

Publication number: 20100225538Abstract: The elements of a phased array antenna are driven by different frequencies, rather than the same frequency, to realize a scanning beam. The scan rate of the beam may be set arbitrarily high according to the frequencies used to drive the phased array, without expensive phase modulators. In particular, each successive element of the phased array antenna is driven with a frequency that is offset from the frequency used to drive the previous element in direct proportion to the spacing between antenna elements. Thus, for a straight line implementation of a phased array antenna with an antenna spacing offset of ?/2, the frequency offset between adjacent antenna elements is constant. For implementations of phased array antennas with another linear or a non-linear spatial relationship between antenna elements, the frequency offset between adjacent antenna elements is determined based on a linear or non-linear spatial relationship of the antenna.Type: ApplicationFiled: May 17, 2010Publication date: September 9, 2010Applicant: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Oved ZUCKER

Publication number: 20070280305Abstract: A microchip, Q-switched, cavity-dumped laser is end-pumped by VCSEL or a laser diode and comprises an electro-optic Q-switch mechanism actively controlled by photoconductive switches. The fast response time of the system and its small dimension produce short pulses (ten pico-second range), with high energy (uJ range). The microchip structure may be built using planar, wafer-like components such that a high-density array of lasers may be manufactured without tight alignment tolerances, providing efficient power or energy scaling.Type: ApplicationFiled: June 5, 2006Publication date: December 6, 2007Inventor: Oved Zucker

Patent number: 7197209Abstract: A single fiber optic cable is configured as a multiplexer/demultiplexer that allows wavelengths to exit the fiber along its length and feed an optical sensor network in a cost efficient and space efficient manner. The fiber may be implemented as a multimode optical fiber that includes a plurality of Fiber Bragg Gratings that are tilted relative to the axis of the multimode fiber. Each grating is used to reflect multiple wavelengths of light out of the fiber depending on the diameter and the number of principal modes of the fiber. The plurality of FBGs allows light at multiple wavelengths to be extracted from the fiber at multiple locations along its length. At each location, reflected light at multiple wavelengths extracted from the multimode fiber may be fed through a plurality of fiber optic paths to optical sensors banks of optical sensors.Type: GrantFiled: July 15, 2004Date of Patent: March 27, 2007Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Yannick Morel, Oved Zucker
