A conductive hinge is made of a superelastic shape memory alloy such as nitinol (NiTi) having a large elastic strain limit for enabling the hinge to bend to a small radius during stowage and flexible return to a trained rigid hinge position by training the shape memory alloy to assume a predetermined deployed configuration when released from a stowage configuration. The hinge is trained by forging at a temperature above a training temperature. The hinge is stowed and released in the superelastic state to deploy solar cell panels as the hinges unfold to the trained deployed configuration.

A high average-power microwave window is provided whose thermal conductivity has been enhanced to enable it to transmit higher average RF power levels than conventional windows of the same size. Such a window is suitable for use with high-average power RF sources such as klystrons and magnetrons. The window comprises a ceramic substrate, typically a low-loss ceramic such as alumina or quartz, to which narrow strips of a high thermal conductivity material have been bonded. One such high thermal conductivity material is synthetic polycrystalline diamond, which can be bonded to the surface of a dielectric substrate using a high-temperature cement or can be directly deposited on the surface by a process such as chemical vapor deposition (CVD). High-purity alumina, a commonly-used material for high-power RF windows, has a thermal conductivity of 26.4 W / mx DEG C., while synthetic diamond has a thermal conductivity of 1000 W / mx DEG C., 2.6 times that of copper and 38 times that of alumina. The novel feature is the use of high thermal conductivity strips to increase the effective thermal conductivity of a microwave window by providing low-resistance paths by which heat can be extracted from the window, resulting in a significant increase in the window's power-handling capacity.

Titled “Graham Power, A New Method of Generating Power” inventor David Graham. Graham power is a power plant. In its simplest form, it is an air conditioning / refrigerant system which also produces power. This is accomplished by adding a turbine to an air-conditioning system. The evaporation process extract heat from the air and the turbine converts that heat into power. In fact it is a power generating system. Graham Power recycles the very fuel that it uses. Graham Power does not consume fuel nor does it release CO2 gas to the environment. It simply draws heat from the surrounding air and transforms it into useful power. In the process of extracting heat from the environment it cools the air. This cooling effect is beneficial to the atmosphere which is currently overheating.

A method of enhancing the power transmitted from a satellite includes the steps of modulating a carrier signal at an Earth station. The non-linearity is established of a downlink amplifier on the satellite. The modulated carrier signal is to compensate for the non-linearity of the downlink and / or the uplink amplifiers. The predistorted modulated carrier signal is transmitted in an uplink to the satellite. The uplink carrier is amplified in the downlink amplifier. A downlink signal is to an Earth station, whereby the downlink signal compensates for non-linearities in the downlink amplifier to thereby optimize amplification with minimum distortion of the signals. A system for implementing the method is described.

A preferred chemistry is a lithium / CFx activated with a nonaqueous electrolyte.

A generator apparatus includes a generator, a generator controller, and a rectifier bridge. A detector unit for recognizing a load shutoff is also provided. When a load shutoff is recognized, a switch is controlled to be transmissive so that energy produced by the load shutoff is stored in an energy reservoir.

A miniature energy harvesting device for producing electricity from acoustical energy, stray electromagnetic energy, noise and from energy of different anatomical motions. The device comprises a housing, a mechanical spring engaged with the housing between a static and dynamic state and a first magnet engaged with the mechanical spring. The device further comprises a conductive grid freely moveable within a cavity of the housing. The device further comprises a composite structure comprising a fixed magnet and a piezoelectric material. The composite structure is engaged with the grid and in communication with the first magnet. The first magnet and the fixed magnet apply a force upon the piezoelectric material when the mechanical spring is in the static state to produce a base voltage. Excitation of the mechanical spring causes the piezoelectric material to generate an alternating voltage output having a peak voltage greater than the base voltage.

A power conversion apparatus is provided. The power conversion apparatus includes an AC to DC adapter, an input port, a power conversion control unit, and a restart circuit. The AC to DC adapter converts an AC input voltage into a DC output voltage according to an external signal of an electronic apparatus and provides the DC output voltage to the electronic apparatus. The input port receives the AC input voltage through an AC input terminal. If the power conversion apparatus does not output the DC output voltage to the electronic apparatus, the power conversion control unit turns off the power conversion apparatus. If the restart circuit detects that an insertion action occurs on the input port, the restart circuit transmits a trigger signal to turn on the power conversion control unit in an off mode.
