Abstract: A method includes determining a rotational position of a rotating projectile as a function of an orientation of a sensor on the rotating projectile. The method also includes actuating a steering mechanism on the rotating projectile at the determined rotational position. The method also includes altering the trajectory of the rotating projectile.

Abstract: A synthetic crystal oscillator enables a conventional crystal to be replaced with purely active electronic elements. Stability and performance characteristics are shown to be comparable-to-superior to a conventional crystal oscillator with side-by-side simulations. The synthetic crystal oscillator with purely active electronic elements offers cost, miniaturization and performance benefits. In some examples, the purely active electronic elements include an RLC circuit generate multiple stable concentric oscillations associated with nonlinear resonance used as an oscillator without a conventional crystalline structure coupled to the electrical circuit.

Abstract: The present disclosure relates to a search and protect device for airborne targets including projectiles. The disclosure is directed to a search and protect device for airborne threats of interest within a 360-degree field of view via a spinning device with range finders. The disclosure relates to a search and protect device that can autonomously determine threats and engage said threats with appropriate counter-measures by determining its future location through the use of range finders within an at least three sensor array with a rotating path of a given speed to protect a target. The location of the projectile may be determined using a distance formula and further trigonometry.

Abstract: A method of monitoring a space for armed and dangerous individuals comprises obtaining a series of digital images of the space via a first digital camera; detecting a series of ambient noise levels of the space via an electronic noise detecting device; processing the series of images; processing the series of ambient noise levels; checking for an armed and dangerous individual; and triggering an alarm signal. Processing the series of images may include comparing objects in a first image of the series of images to at least one predetermined weapon patterns; and comparing objects in the first image of the series of images to at least one predetermined human patterns. Processing the series of ambient noise levels may include determining an upper threshold noise level based on the series of ambient noise levels; and comparing a first ambient noise level to the upper threshold noise level.

Abstract: A system and method to expose a material to an ion beam during a continuous material production process may include a vacuum fixture to form the ion beam and a slit in the fixture to allow at least a portion of the ion beam to exit the fixture through the slit. The material can be placed in contact with an exterior area of the fixture so as to cover the slit. With the material in place, the vacuum within the fixture may be maintained and the ion beam formed. The material over the slit can be exposed to the ion beam. As the continuous process moves material past the slit, the vacuum within the vacuum fixture may help to maintain the material in contact with the fixture.

Abstract: Methods and apparatus are provided for ion implantation of a workpiece. The apparatus includes an ion beam generator for generating an ion beam, a deflection device for deflecting the ion beam to produce a deflected ion beam, and a drive device for rotating the deflection device about an axis of rotation to thereby cause the deflected ion beam to rotate about the axis of rotation and to produce a rotating ion beam. The apparatus may include a controller for controlling the deflection and/or the rotation of the ion beam to produce a desired distribution of the ion beam over the surface of the workpiece. The apparatus may further include an angle compensation device for causing the rotating ion beam to have a substantially constant angle of incidence on the workpiece.

Abstract: A method and apparatus for controlling complex systems includes hierarchically coupled subsystems representing operative functions of the system. The hierarchically coupled subsystems are coupled to collect command data from a user and signal data from the system. Each subsystem may include one or more state machines and one or more digital signal processing and conditioning unit (DSPCU) objects. The DSCPU objects accept process commands and convert control system signals into states for further processing by the state machines. Associated with the DSPCUs of each subsystem is a data flow diagram for dictating an order of flow of commands and signals at the DSPCUs. A method of controlling the system represented by the hierarchically coupled subsystems schedules the execution of the subsystems according to an execution protocol.

Abstract: A musical electronic lock 10 is provided to unlock a locking means 12. The musical electronic lock 10 comprises a digital tone generation circuit 20 and memory 18 for electronically producing a musical melody while an electronic logic circuit 16 decodes responses from a user. Responses are compared by the electronic logic circuit 16 with an electronically stored combination and timing information in the memory 18. When successfully operated, the user will activate a switch or switches 24 in a key input unit 14 to input a confidential alphameric code when prompted by particular notes of an electronically synthesized musical melody or other sequenc of audible tones generated by a speaker 22. The necessary information to operate the musical electronic lock 10 is significantly more difficult to disseminate than conventional combinations yet it is is far simpler to operate, due to the easy to remember musical melody.
