  • Publication number: 20100220002
    Abstract: A method for onboard measurement of a deviation in orientation of an object from a desired orientation of the object. The method including: transmitting a polarized RF signal from a reference source, with a predetermined polarization plane; receiving the signal at a pair of polarized RF sensor cavities positioned symmetrical on the object with respect to the predetermined polarization plane; analyzing an output of the pair of polarized RF sensor cavities resulting from the received signal; and determining the deviation in orientation of the object relative to the predetermined plane based on the analysis. The method can further include controlling the object based on the determined deviation in orientation.

  • Patent number: 7717023
    Abstract: Apparatus and accompanying methods for the detection and subsequent destruction or disablement of Improvised Explosive Devices (IEDs) while maintaining a satisfactory level of human safety. Operationally, our inventive method and apparatus detects the IED using one or more methods including: detecting internal battery components; detecting magnetic signature(s) of the IED; detecting a characteristic energy spectrum of the IED; and/or detecting characteristic chemical signatures of the device(s). Once detected, the device may be further characterized and then subsequently deactivated and/or destroyed by a shaped pulse charge directed at the device or its power source (battery) from a safe distance.

  • Patent number: 7506586
    Abstract: A munitions energy system combines various sources of energy generation with energy storage to provide power to a munition through various stages of the munition's operation. The system uses energy harvesting technologies which convert energy captured from the environment of the munition to electrical power which can be used to meet the munition's power needs. Energy can be harvested from the mechanical, thermal, and electromagnetic environment of the munition. The harvested energy can be stored by the system for later use. The system can also receive energy from conventional sources such as batteries and manage the energy from all sources to meet the power requirements of the munition.

  • Patent number: 7425918
    Abstract: Methods are provided where: a signal is transmitted from an illuminating source and received cavity waveguides disposed on an object; a position and/or orientation of the object is determined based on the signal received in the waveguides; and data representing the determined position and/or orientation is transmitted to a remote location or generated for use in the object. The illuminating source can also be moved to indicate a change in a predetermined trajectory or target position where a new position and/or orientation of the object is determined based on the signal received in the waveguides and the object is controlled to change the predetermined trajectory or target position to the indicated new predetermined trajectory or new target position. A change can also be detected in the predetermined trajectory or target position and the object controlled to correct the change.

  • Patent number: 6724341
    Abstract: An autonomous onboard absolute position and orientation referencing system provides a means of efficaciously and economically embedding guidance and control components into the fins of supersonic, highly maneuverable small, medium-caliber and long range munitions. Embedded resonant cavities form an integral part of the referencing system. The magnitude and phase information received by the integral antennas is used to determine the munition orientation. Embedded sensors provide continuous, onboard information about the angular orientation of the munition, such as its pitch, yaw, and roll angles, as well as its absolute position relative to a ground station.

  • Patent number: 6626040
    Abstract: A sensor including: a base; at least one component which moves relative to the base; and a locking device for locking the at least one component in a predetermined stationary position in response to an external stimulus. Where the sensor is an accelerometer, the external stimulus is preferably an acceleration of the sensor in which case the locking device locks the at least one component during periods in which the acceleration exceeds a predetermined value. The predetermined stationary position can be a null position taken by the at least one component corresponding to an acceleration that is substantially zero or an active position taken by the at least one component when acceleration equals a predicted acceleration other than zero. Further, the locking device can lock the at least one component actively or passively.

  • Patent number: H1751
    Abstract: Remote telemetry control in the testing of multiple projectiles such as rets, simultaneously fired, in an environment requiring extremely low power dissipation in the inactive state and experiencing extremely high-G accelerations during launch. On-board battery charging, battery and telemeter conditioning and telemeter control are remotely effected in a highly reliable manner through interfacing a portion of which is on board each projectile and another portion of which is remote from the projectiles and also remotely controlled for safety reasons. The aforementioned on-board functions are prioritized to accomplish first the charging and conditioning requirements, whereby telemeter activation during same is prevented, and the control signals governing charging, conditioning and telemeter operation are electronically isolated to prevent spurious activation. Electronic switching circuitry is incorporated to protectively ensure deactivation of the telemeter during higher priority operations.
