Active armor protection system for armored vehicles


A sensor system for defending armoured vehicles against projectiles through the use of active armour. A thermal sensor detects a projectile's presence, and a laser proximity sensor determines its location. A doppler sensor distinguishes between threatening and nonthreatening projectiles by measuring the projectile's velocity. The sensors are positioned in a housing with a segmented spherical window, wherein each sensor can detect the projectile through a window segment having a filtering characteristic which is matched to its associated sensor. An eyelid shutter, which can open and close, protects the window from small arms fire and shrapnel. A conical deflector protects the sensor system from objects such as tree branches. Heater elements are used to clear ice and snow from the window, and the eyelid shutter removes other material through the use of a cleaning liquid delivery system and rubber wipers.

Chovan , et al. March 30, 2004

Sensor for optically sensing air borne acoustic waves


The present invention relates to an optical sensor of air borne acoustic waves. The sensor comprises means for producing mutually coherent optical sampling and reference beams, which may be combined to form an intermediate frequency carrier, the sampling beam being exposed to the acoustic field, in which acoustic wave induced density variations occur. These density variations produce a variation in the index of refraction and thereupon a phase modulation of the sampling beam. This phase modulation may be recovered by an optical detector and a phase detector as an electrical signal representative of the acoustic signal. The invention has application to security systems.

Application of a mixed metal oxide catalyst to a metallic substrate


A method for applying a mixed metal oxide catalyst to a metallic substrate for the creation of a robust, high temperature catalyst system for use in decomposing propellants, particularly hydrogen peroxide propellants, for use in propulsion systems. The method begins by forming a prepared substrate material consisting of a metallic inner substrate and a bound layer of a noble metal intermediate. Alternatively, a bound ceramic coating, or frit, may be introduced between the metallic inner substrate and noble metal intermediate when the metallic substrate is oxidation resistant. A high-activity catalyst slurry is applied to the surface of the prepared substrate and dried to remove the organic solvent. The catalyst layer is then heat treated to bind the catalyst layer to the surface. The bound catalyst layer is then activated using an activation treatment and calcinations to form the high-activity catalyst system.

System and method for suppressing radio frequency transmissions


A system and method for suppressing radio frequency ("RF") transmissions includes a transmitter for transmitting electronic signals that suppresses (e.g., prevents, disrupts, jams, interferes with or otherwise disables) RF transmissions. Some embodiments of the invention include a transmitter that suppresses one or more signals transmitted from a target transmitter in an RF transmission system to a target receiver in a wireless device operating in the RF transmission system to prevent, disrupt, jam, interfere with or otherwise disable an RF transmission between the target transmitter and the target receiver in the wireless device (i.e., target wireless device). These systems and methods may be used to interrupt communication, command and control of non-friendly combatant. These systems and methods may also be used to suppress RF transmissions to prevent the detonation of improvised explosive devices, or IEDs.

Method and system for synchronizing and selectively addressing multiple receivers in a wireless, spread spectrum communication system


A system and method for synchronizing and selectively addressing multiple receivers in a wireless communication system includes a spread spectrum transmitter and one or more spread spectrum receivers. The transmitter transmits a signal having an observable parameter which is pseudo-randomly varied. The receiver measures the relative times between recurrences of a selected value of the observable parameter being pseudo-randomly varied, and determines an initial state of the transmitter based upon the measured relative times. The receiver then synchronizes itself to the estimated current state of the transmitter using the determined initial state as a starting reference. In a frequency hopping embodiment, the spread spectrum transmitter comprises a feedback shift register, and transmits a sequence of pseudo-randomly hopped frequencies determined by the shift register. A receiver is tuned to one of the hopping frequencies, measures the relative times of arrival between consecutive transmissions, and determines the initial code word in the transmitter feedback shift register from the measured relative times of arrival by constructing and solving a set of linear equations. The receiver then matches comprises its feedback shift register to the initial code word, adjusted by an amount of time elapsed during the synchronization process. Similar techniques may also be applied both to direct sequence spread spectrum communication systems.

Reactive composite material structures with electrostatic discharge protection and applications thereof


Applicants have discovered that electrostatic discharge (ESD) may, in some circumstances, result in current densities sufficient to ignite unprotected reactive composite materials. They have further discovered that a reactive composite material (RCM) can be protected from ESD ignition without adversely affecting the desirable properties of the RCM by the application of conducting and/or insulating materials at appropriate locations on the RCM. Thus ESD-protected RCM structures can be designed for such sensitive applications as ignition of propellants, generation of light bursts, and structural materials for equipment that may require controlled self-destruction.

Method and apparatus for the detection of objects using electromagnetic wave attenuation patterns


A method for detecting an object, comprising the steps of defining expected characteristics of scattered electromagnetic radiation to be received at a receiver; attenuating at least a portion of electromagnetic radiation received at the receiver by a presence of an object within a path of electromagnetic information; and detecting the attenuation to indicate a presence of the object. The object may be a low radar profile object, such as a stealth aircraft. The electromagnetic radiation is preferably microwave, but may also be radio frequency or infrared. By using triangulation and other geometric techniques, distance and position of the object may be computed.

Rocket thruster comprising load-balanced pintle valve


A rocket thruster of this invention includes a nozzle and a valve assembly. The valve subassembly includes a pintle with a head portion, which has a truncated substantially conical surface region facing and concentric with converging and throat regions of the nozzle to provide a variable effective throat area therebetween. The truncated portion of the head portion has an outer edge defining a bleed passageway opening communicating with a primary bleed passage leading through the head portion to a bleed cavity located on an opposite side of the head portion. During activation of a rocket motor to which the rocket thruster is coupled, gases imparting a load on the head portion pass through the primary bleed passage to the opposite side of the head portion for counterbalancing loads acting on the head portion. A thrust control subassembly moves the pintle axially for changing the effective throat area.

Disabling a target using electrical energy


One system described herein provides electrical energy by means of a Tesla coil that generates a strong electric field in the vicinity of an electrical target. An energy booster provides additional electrical energy to increase the probability of disabling and/or disrupting the electrical target. For example, an electrode may be configured with the Tesla coil to form the electric field of the electrical target. The electric field may cause a breakdown in the air about the Tesla coil that allows electric current to conduct to the electrical target. The Tesla coil may repetitively burst the electric field such that pulses of electric current are conducted to the electrical target.
