Abstract: An electronic structure includes an electronic device, and a heat sink assembly in thermal contact with the electronic device. The heat sink assembly is formed of a piece of pyrolytic graphite embedded within a metallic casing and intimately contacting an interior wall of the metallic casing. The heat sink assembly is substantially fully dense. The heat sink assembly is fabricated by assembling the piece of pyrolytic graphite within the disassembled elements of the metallic casing, and then simultaneously heating and pressing the initial assembly until it is substantially fully dense.

A cover plate (28) is mounted to the superstructure (22) over the cavities (40) to form cavity style filters. Amplifiers (32) and antenna elements (30) are then affixed to the superstructure (22) and cover plate (28). Ideally, the cover plate (28) is affixed to the superstructure (22) using an electrically conductive adhesive.

Abstract: A ceramic-polymer composite material such as part of a microelectronics package is formed of a ceramic mixture of aluminum nitride and boron nitride, and a low-loss polymeric material. The amount of aluminum nitride is preferably from about 50 to about 90 weight percent of the ceramic mixture, but the relative amounts of the two ceramics may be adjusted to achieve thermal expansion and thermal conductivity properties required for a particular application. A mixture of the ceramics and uncured thermosetting polymeric resin is formed, pressed into the shape of the microelectronics base and/or lid, and heated (either concurrently or subsequently) to compress the mixture and cure the polymer.

Abstract: An electronic structure is formed of alternating layers of a metal and a cured ceramic-polymer mixture. The ceramic-polymer mixture is prepared by mixing small ceramic particles into a flowable, curable polymer. The mixture is spread over a first metallic layer and, optionally, B-stage cured. Additional metallic layers and ceramic-polymer layers are added in alternating fashion. Metallic interconnects may be provided through overlying ceramic-polymer layers to a particular metallic layer. The resulting structure is heated to a moderate temperature to cure the polymer.

Abstract: A headrest suitable to be mounted on a vertical surface such as a rear window for vehicles is disclosed. At least one layer of plastically deformable material and at least one layer of resilient material is used to provide energy absorptive protection for the vehicle occupant's head. Vertical position adjustment may be provided on a transparent backing plate. Various signals and insignia may be inscribed on the side of the backing plate mounted toward a window.

Abstract: A pressure controller device for selectively applying and relieving a measured pressure upon a closed volume of fluid includes a housing, a barrel defining a fluid chamber and a plunger for axial movement within the fluid chamber for applying measured pressure to a fluid therewithin. The barrel has a port for delivery of fluid at measured pressure, and moves axially within the housing in a first axial direction in response to increased pressure within the chamber. The housing and barrel are biased apart, e.g., by a first biasing spring acting with a known force upon the barrel in an opposed, second axial direction. Indicia upon the barrel and housing indicate the relative positions of barrel and housing. As pressure in the fluid chamber increases, the barrel is urged in a first direction with a force proportional to the measured pressure to overcome the known force in the second direction, the relative positions of barrel and housing providing a measure of the pressure within the fluid chamber.

No tool is required to connect the termination device to the conductor.
