Abstract: A method is disclosed for the fabrication of a tunable radio frequency (RF) power output filter that includes fabricating a core body and then forming a plastically deformable metallic shell over the exterior surface of the core body.

Abstract: The present invention provides an initial strike-face layer for armor, a method of constructing an armor plate and armor. In one embodiment, the initial strike-face layer includes a substantially planar surface having a relief pattern with raised or recessed structures, each of the structures having sides that are oblique to the substantially planar surface.

Abstract: A method for conducting heat between a heat source and a heat sink includes disposing under a compressive force therebetween a plurality of thermally conducting unit cell structures that mechanically cooperate to form thereby a body structure having an aggregate thermal conductivity that changes in response to a compressive force exerted thereon, wherein an amount of said plurality of thermally conducting unit cell structures disposed therein is selectable to affect thereby a desired aggregate thermal conductivity in response to the compressive force.

Abstract: A weather resistant cabinet for housing electrical equipment includes a one-piece, unitary tubular housing. The tubular housing has two open ends and is preferably formed from aluminum using a deep-drawing process. Two covers are attached to the two open ends of the tubular housing. The two covers include heat sinks and are preferably formed from aluminum using an extruding process. The covers are attached to the tubular housing using either mechanical fasteners and a gasket, or by a dip-brazing process.

Abstract: A heating/cooling apparatus for electronic components of a wireless base station is described. The apparatus includes a heat exchanger having a material-filled chamber and a plurality of extrusions. The chamber is located adjacent to the electronic components. A heater is provided within the chamber. The material within the chamber, which is preferably a liquid, serves to conduct heat from the electronic components to the extrusions. The heater serves to heat the material within the chamber, which in turn conducts that heat to the electronic components, when heat is required to maintain operation of the components with prescribed parameters.

Abstract: A lockable piano-type hinge assembly including a locking hinge piece in addition to two hinge pieces which include the hinge pin barrels. The hinge pin is secured to the locking hinge piece which has an opening aligned with a locking loop secured to one of the hinge pieces. When the hinge assembly is assembled, the locking loop extends through the opening of the locking hinge piece and a locking device is insertable through the locking loop to prevent relative movement of the locking hinge piece and removal of the hinge pin from the barrels.

Abstract: Outdoor, electronic component containing cabinets are cooled by forced circulation of outside air through the cabinet for direct, cooling contact with the components. The incoming air is filtered, heated as necessary to evaporate water droplets in the air prior to entry of the air into the component containing portions of the cabinet, and the air flow is regulated for slowing the flow rate of the air within the cabinet as is necessary for maintaining the relative humidity within the cabinet below a maximum percentage; typically 40%.

Abstract: A structure on which various equipment, particularly outdoor electronic cabinets, can be mounted comprises a shallow, box-like frame including rigid sides, bottom plates secured to the sides, and cross braces extending between and secured to opposite sides. For rigidity and strength, the cross braces comprise U-beams having upper and lower laterally extending flanges, the upper flanges serving as horizontal surfaces for the mounting of equipment on the support. In a preferred use, the support structure is placed on the ground at a cleared outdoor site and locally available ballast is loaded into the structure for firmly anchoring it in place.

Abstract: An EDS tester is combined with an employee identifier and recording monitor so as to provide and audit trail of compliance with the fact of ESD testing and, if desired, a record of the ESD test results such as body resistance or charge. In one illustrative embodiment, a fingerprint identifier pad is used together with the ESD test to identify a unique biological characteristic of the worker being tested. In addition, the feature of providing physical contact with the workers body typically required for ESD testing may be combined with the fingerprint identifier pad thereby enabling the ESD test results to be correlated with a specific individual.

Abstract: Apparatus performs active, dynamic balancing of a rotating machine by shifting the spatial distribution of an inertial liquid within a body that co-rotates with the rotating shaft of the machine. The body includes chambers, substantially disposed at equal angular intervals, for containing the inertial liquid. The chambers communicate through a channel lying at or beyond the outermost radial position of the outward ends of the chambers. A motive element or elements are provided for impelling the inertial liquid through the channel. The chambers, channel, and motive elements form a sealable system.

Abstract: Temperatures along the surfaces of water tubes in an operating steam boiler are determined by detecting infrared radiation emitted from the tube surfaces in one or more narrow pass-bands founds to be available despite the presence of hot and turbulent flue gases between the sensor and the tube surface to be measured.

Abstract: This invention employs principles associated with air-lubricated thrust bearings, to provide highly sensitive indicators of the presence of defects along the surface of a cable insulative layer. A spring-loaded mounted probe containing an axial air passage is closely directed at the cable surface. The cable is moved linearly under the probe, and air is introduced to create air flow at and along the surface in the vicinity of the probe's outlet oriface. The static pressure at the probe outlet oriface is essentially constant, until a surface defect such as a scratch or a protrusion causes a substantial change in the air pressure or air flow rate. The change is detected and recognized as an indication of defect.

Abstract: A combination latch/switch mechanism is operative to lock a circuit board into a support housing and enable and disable selected circuits during the insertion process. A lever of the mechanism includes a notch to engage the support housing and a contact arrangement engaging and disengaging circuit paths as the circuit board is inserted into the housing.
