An electrical device that comprises a tunable cavity filter that includes a container and a post. The container encloses a cavity therein, wherein interior surfaces of the container are covered with a metal layer. The post is configured be movable through an opening in the container such that at least a portion of the post is locatable inside of the cavity.

Microwave and millimeter-wave compact tunable cavity filter

A reel for storing optical fiber is disclosed that significantly reduces the torsional force applied to optical fiber as the fiber is being wound onto the reel for storage. The optical fiber reel comprises two spindles that are offset with respect to the rotational center of the reel. Such an arrangement causes the fiber to be wound onto the reel in a substantially linear fashion, thus preventing the torsional force and resulting twisting that cause micro-cracks to develop. The spindles are of a sufficiently large diameter to facilitate operational use of the fiber while stored on the spindle without increasing the attenuation of signals that could result from the use of a smaller diameter spindle.

Method and apparatus for operational low-stress optical fiber storage

A method and apparatus are disclosed for suppressing interference in a radio frequency (RF) communication system using active shielding techniques. An opposing neutralizing signal is applied to actively neutralize stray signals in a microwave communication environment. An interfering or stray signal is detected using a sensing antenna, and the opposing neutralizing signal is generated in response thereto. The opposing neutralizing signal is applied to a signal neutralizing shield to shield any desired components or devices. The opposing neutralizing signal is approximately 180 degrees out of phase, and of equal magnitude to the detected interfering signal. A phase shifter/null feedback device receives the detected stray signal, if any, and adaptively adjusts the phase and magnitude of the opposing neutralizing signal. In one embodiment, the phase shifter/null feedback device includes an integrator that generates a DC value that is proportional to the energy of the interfering signal. The DC value is applied to a voltage controlled oscillator (VCO) using known feedback techniques to adjust the phase or magnitude, or both, of the opposing neutralizing signal and to thereby minimize the DC value.

A patch antenna's resonators are supported by a non-conductive frame. The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. In one embodiment of the invention, the frame includes a perimeter lip that snaps over the edges of the feedboard and thereby attaches the frame to the feedboard.

Patch antenna using non-conductive thermo form frame

An inexpensive, easy to assemble patch antenna is disclosed where unwanted polarizations in the transmitted RF energy are minimized. A feedboard, spacer and resonator are held in a compressed relationship by two halves of the antenna housing. The spacer is a thermo-formed sheet with semi-spherical spacers. The spacers have a height that provides the desired spacing between the feedboard and the resonator.

An opto-electric apparatus includes a circuit board, an opto-electric converter module with a plurality of electrical leads, a holder rigidly holding the opto-electric converter module, and a connection structure. The holder is rigidly fixed to the circuit board, and the connection structure is rigidly connected to the holder. The leads of the module protrude into holes in the structure. The structure electrically connects the circuit board to the leads.

Mounting opto-electric modules on circuit boards

An apparatus for storing anti-tank ammunition including a tube with a first cap disposed at a first end of the tube, and a second cap disposed at a second opposing end of the tube. The first cap includes a one-way valve which allows gas to escape the tube, but which prevents gas from entering the tube. The apparatus reduces the amount of corrosion which forms on the ammunition, thereby substantially lowering the number of backfires of the ammunition.

Corrosion protection system for anti-tank ammunition

The present invention provides a grounding system for discharging static electricity. The grounding system includes a body-contacting member which forms an electrical connection with at least a portion of a human body and a grounding cable. The grounding cable has an elongated conductive member with a first end for connection to ground potential and a second end for electrically communicating with the body-contacting member. At least one end of the elongated conductive member is embedded within a resistive material having an electrical conductivity of 10.sup.5 -10.sup.12 ohms/square. In one embodiment, the body-contacting member is a wrist or ankle strap while the resistive material is a polymer loaded with conductive and semiconductive particles. Exemplary conductive particles are selected from carbon, metals, and mixtures thereof.
