Abstract: A reflected energy detecting device includes a transmitter for transmitting an electromagnetic signal and a receiver for receiving a reflected electromagnetic signal. An antenna may be operatively connected with the transmitter and the receiver for radiating the electromagnetic signal and capturing the reflected electromagnetic signal and the antenna may be movable. A main controller may be provided for controlling operation of the transmitter and the receiver and the movement of the antenna and the reflected energy detecting device may further include at least one platform. The at least one platform may support a remote reflector that is dimensioned and configured to redirect the transmitted electromagnetic signal in a desired direction and a platform controller that is configured to communicate with the main controller and to maintain alignment between the remote reflector and the antenna.

Abstract: A liquid immersed pumped solid state lasing system comprising a light source and a lasing element spaced from the light source. The light source and the lasing element are mounted in an insulated container. The top of the container is open for inputting a clear cryogenic cooling liquid into the container to totally immerse the light source and the lasing element in the liquid. Heat transfer occurs by conduction from the light source and the lasing element to the liquid thereby cooling the light source and the lasing element to cryogenic temperatures. The container has a window for the output of laser light. A plurality of electrical leads which are superconducting at cryogenic temperatures are attached to the light source. When the leads are connected to a power supply outside the container, the light source directs light on the lasing element so that the lasing element is excited and transmits a light output through the window.

Abstract: A laser pulse fiber optic neutron detector which is capable of discriminating against background neutrons and gamma rays while measuring both the energy of an incoming neutron and its direction has a sensor having a plurality of vertically-stacked organic fiber light pipes and a reflector at one end of the light pipes. Ionized tracks in the light pipes caused by neutron radiation are detected by directing pulsed laser radiation into one end of the light pipes and detecting the laser radiation backscattered and reflected from the light pipes.

Abstract: An integrated filter and shielded ignition assembly locates all ignitable terials inside of the sealed metallic enclosure. The sealed metallic enclosure is present to prevent electromagnetic radiation interference and thereby enables the enclosure to have only one path where electricity can flow. The filter is considered a low bandpass electric filter. The filter does not interfere with the ordinary electric function of the ignition assembly.

This TVSDA provides for one connector to be mounted in a plane at each end of the assembly. This mounting arrangement enables bulkhead mounting of the TVSDA. VSD's are connected, in a low parasitic inductance fashion, between leads interconnecting separate connector pins and the body of the TVSDA.

Voltage suppression devices are connected, in a low parasitic inductance fashion, between leads interconnecting separate connector pins and the body of the TVSDA. The TVSDA has a minimum VSD lead length.

Abstract: This filtering transient voltage suppression device assembly adequately pides for filtering of electrical noise and transients. It also provides a circuit with reduced parasitic inductance of the voltage suppression device (VSD). It provides for connector units to be mounted in planes at each end of the assembly. This mounting arrangement enables bulkhead mounting of the FTVSDA. Filters and VSD's are connected, in a low parasitic inductance fashion, between leads interconnecting separate connector pins and the body of the device. A mounting plate inside the device provides structure and electrical connections for assembly, as well as easy access.

Abstract: A method for making a thin film layered semiconductor laser which includes depositing layers of semiconductor and electrical lead materials on an undoped semiconductor substrate and heating each layer of the semiconductor material after it has been deposited to improve crystallinity of the deposited semiconductor material and to improve interfaced continuity of the material at the lasing interface and at the electrical conductor to semiconductor interface, and after the desired number of layers of semiconductor and electrical lead materials have been deposited, cutting and polishing the ends of the laser device and finally placing a non-conductive dielectric reflecting surface on one of the polished end surfaces of the laser.

Abstract: The electromagnetic energy is captured by the antenna and changes the reftivity of a Liquid Crystal Display (LCD) proportional to the field being measured. The LCD is illuminated by a fiber optic and this light is reflected from LCD proportional to the electromagnetic field. This field proportional light is captured by a fiber optic and transmitted to a photodetector where it is converted to an electrical signal proportional to the electric field. This electrical signal may then be displayed, recorded or processed with other information.

Abstract: A multiple cell electromagnetic radiation testing system includes a plurality of isolated strip transmission line cells coupled in electrical series and having aligned apertures in the walls of the cells. With this arrangement the respective cells bounded waves add to simulate application of a single electromagnetic radiation field at test specimens located in the apertures of the cell walls. Each cell has a plate-to-plate dimension that is small compared to a wavelength of the highest test frequency. The phase and arrival time of each cell voltage is controlled to simulate electromagnetic radiation impingement of the test sample at selected angles.

Fiber optics have an almost unlimited information transfer rate and does not have the electrical interference problems of the wire systems.

Abstract: The switch is mounted on a cantilever spring which has a contact that can be positioned over and engage individual contacts of a large bank of contacts. A device is mounted on the spring so as to be responsive to forces either electrostatic, magnetic, gas or liquid pressure. These forces selectively select one of the contacts of the bank of contacts.

Abstract: A system for depositing and definitely positioning optical fibers on a base material. The process includes depositing a cladding base on a plastic tape by radio frequency triode sputtering. A slitted mask is placed over the cladded tape and fiber core material is sputtered onto the cladded surface in a controlled manner to form strips of fiber cores on the cladded base.
