    Abstract: Method for laser machining explosives and related articles. A laser beam is directed at a surface portion of a mass of high explosive to melt and/or vaporize the surface portion while directing a flow of gas at the melted and/or vaporized surface portion. The gas flow sends the melted and/or vaporized explosive away from the charge of explosive that remains. The method also involves splitting the casing of a munition having an encased explosive. The method includes rotating a munition while directing a laser beam to a surface portion of the casing of an article of ordnance. While the beam melts and/or vaporizes the surface portion, a flow of gas directed at the melted and/or vaporized surface portion sends it away from the remaining portion of ordnance. After cutting through the casing, the beam then melts and/or vaporizes portions of the encased explosive and the gas stream sends the melted/vaporized explosive away from the ordnance. The beam is continued until it splits the article, after which the encased explosive, now accessible, can be removed safely for recycle or disposal.

    Abstract: A secured network system comprising a readykey controller which has a first card reader and a power relay switch connected thereto. The user of the stem inserts a microchip embedded card into the first card reader which then transmits an authorization signal to the readykey controller. The readykey controller then activates a power relay switch affixed to the computer which connects the computer's power supply to an external power source activating the computer. The secured network system also has a data relay switch which includes a manual A/B secured network switch. The manual A/B switch allows the user to receive and process classified data, by setting the switch to a predetermined position which connects a secured network server to the computer. The user inserts his proximity card into a second card reader which transmits a second authorization signal to the readykey controller. The readykey controller, responsive to the second authorization signal, activates the data relay switch. Activating the data relay switch connects the secured network switch to the secured network server via the data relay switch which allows for the transmission of classified data between the secured network server and the personal computer.

    Abstract: A magnetic gripper provides a support for releasable attachment to a ferromagnetic surface. A magnet adheres the gripper to the ferromagnetic surface. A frame is rotatably attached to the magnet where the frame defines cam surfaces to raise and lower the magnet from the ferromagnetic surface. An ear extends from the magnet to engage the ferromagnetic surface at a location spaced from the cam surfaces so that an end of the magnet near the ear can be first disengaged from the ferromagnetic surface, causing an air gap between the magnet and the ferromagnetic surface. The remainder of the magnet is sequentially disengaged from the surface as the cam surface is rotated. A foot support may be rotatably mounted to the frame so that a user can stand on the gripper to perform maintenance and repairs on the structure defined by the ferromagnetic surface.

    Abstract: The device has a semiconductor chip having active circuitry in the face thereof. The circuitry has busing over it containing two conductive layers having a plurality of contacts and vias with spacings between them that alternate with respect to one another to provide current ballasting and improved switching uniformity. The spacings between the alternating contacts and vias provide regions of maximum conductor thickness and therefore reduces the busing resistance. Staggering the rows of alternating contacts and vias provides further current ballasting. A first conducting layer is used to contact and provide electrically isolated low resistive conducting paths to the various semiconductor regions while the second conducting region is used to provide selective contact to the first conductive layer, thus providing a means of busing large currents over active semiconductor area without sacrificing performance parameters.

    Abstract: A shared spectrum communications unit and system provides communications without interfering with incumbent point-to-point receivers. This system includes a transmitter (e.g., of a PCS device) and a geographical location device which is operatively associated with the transmitter. The geographical locating device determines the position of the transmitter, and provides position information to a frequency authorization device. Geographical information pertaining to the PCS device is compared with the locations of the incumbent point-to-point receivers, using a database of the frequency authorization device including the locations of the point-to-point receivers, and a frequency allocation/authorization is generated to the PCS device when the PCS device is located outside of a predetermined range associated with local point-to-point receivers. An authorized frequency is stored and employed by the frequency authorization device for control of the operating frequency of the PCS device.
