Abstract: An apparatus for producing high yields of carbon nanostructures is disclosed. The apparatus includes an electric arc furnace and a feeder that directs solid carbon dioxide into an electrical arc generated by the electric arc furnace. Carbon nanostructures are produced within the electrical arc without producing magnesium oxide (MgO).

Abstract: A camera used to acquire video images at the remote site having a means for acquiring a video image, a wireless transceiver for transmitting the video images to a wireless Internet router. The camera includes a built-in web server for serving the images over the Internet to client computers having standard Internet web browsers. Moreover, the camera further includes an enclosure supporting the image acquisition means and web server hardware, a battery in a circuit with the camera, a hand operated switch adapted to close the circuit, and a handgrip for use by an operator in carrying the camera.

Abstract: A work site monitoring and employee time tracking system that includes a work site Internet connection having a broadband modem in communication with a router for transporting data to and from the work site and a work site IP camera in communication with the router for transporting images from the work site to client computers in communication with the Internet. A biometric fingerprint scanner for identifying and clocking-in and clocking-out work site workers is also included. The biometric scanner is in communication with the router for transmitting identification, clock-in and clock-out data to a server computer in communication with the Internet.

Abstract: A remote imaging system for the unattended acquisition of image data at a first site and wireless transmission of the image data to a remote Internet server via a cellular modem. The system includes at least one analog video camera and a first frame grabber to receive image data in analog format from the video camera and convert the image data to digital format for transmission over the Internet. The invention also includes a method of automatically selecting images for storage. The method includes steps of acquiring a plurality of images of an area, comparing each image against first predetermined criteria, and separating each image that meets said first predetermined criteria from images that do not.

Abstract: An aircraft having a memory loaded with geolocation data corresponding to restricted airspace boundaries and an autonomous system for rerouting the aircraft outside of the restricted airspace boundaries as the aircraft approaches to within a predetermined distance of the restricted airspace.

Abstract: The present invention relates to a system for retrieving data from remote difficult to reach terrain, such as wilderness areas, etc. and in particular to a system comprised of one or more surface based data collectors in communication with one or more wireless transceivers adapted to transmit the collected data to an unmanned aerial vehicle adapted to fly within a predetermined distance from the data collector and receive data collected therefrom. The present invention further relates to an unmanned aerial vehicle adapted to fly a flight pattern relative to a moveable surface object or for controlling the position of a moveable surface object relative to the flight path of the unmanned aerial vehicle. Finally, the present invention relates to an improved unmanned aerial vehicle having airframe structural elements with electrical circuits adhered to the surfaces of the structural elements.

Abstract: The present invention is an aircraft having a memory loaded with geolocation data corresponding to restricted airspace boundaries and an autonomous means for rerouting the aircraft outside of the restricted airspace boundaries as the aircraft approaches to within a predetermined distance of the restricted airspace.

Abstract: The distance to a target is determined by transmitting a radio frequency signal comprised of a plurality of pulses to a target from a transmitter at a given transmission time, receiving a plurality of return scans at a receiver, selecting a scan meeting a predetermined parameter that includes a reflected pulse; comparing the scan with a template of a reflected pulse at different locations to select the time at which the match between the scan and the template have the closest match; and calculating the distance to the target. The signal is transmitted and received through a wall of an aperture-free container that is transparent of said radio frequency pulses. The device also includes a barrier plate that is opaque to radio frequency pulses between the transmitter and receiver.

Abstract: A system is described for discriminating between a transmitted signal and background noise comprising a transmitter adapted to transmit a signal including first and second pulses, separated by a predetermined time interval; and a receiver including a pulse detector to detect pulses received from the transmitter; a delay circuit adapted to delay transmission of the first pulse for a predetermined period of time in communication with the detector to receive a pulse therefrom; and an AND gate having an output, a first input in communication with the delay circuit and an second input in communication with the detector, the time of transmission between the pulses equaling the time delay of the delay circuit, whereby the AND gate allows transmission of a signal only when simultaneously receiving pulses from the detector and the delay circuit.
