摘要:
The present invention relates to a solid-state optically activated switch that may be used as limiting switch in a variety of applications or as a high voltage switch. In particular, the switch may incorporate the photoconductive properties of a semiconductor to provide the limiting function in a linear mode. In one embodiment, a configuration of the switch allows for greater than 99.9999% off-state transmission and an on-state limiting of less than 0.0001% of the incident signal.

A modular, lightweight, high-survivable, photovoltaic flexible blanket assembly for a space solar array is disclosed. The modular blanket is an accordion foldable or rollable flexible photovoltaic solar panel blanket assembly comprising a plurality of common photovoltaic modules spaced in an orthogonal pattern. Each module is mechanically attached with multiple low profile fasteners on their backside to an open weave mesh tensioned backplane structure. The backplane forms a tensioned dimensionally stable planar surface in the deployed configuration onto which the modules are suspended. Each module is common and comprised of a rectangular substrate that includes solar cell assemblies, circuitry, exposed electrical contacts for integration of blanket-level harnessing, and frontside and rearside shielding and coatings as required for the mission application. The blanket assembly may be dispersed with an open pattern of compliant and formable material on the backside to provide insulation against the vigorous vibration of the launch environment.

A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom is provided. Power transmitters can be coordinated as a phased array and the power generated by the phased array is transmitted to one or more power receivers to achieve remote wireless power generation and delivery. In many embodiments, a reference signal is distributed within the space-based solar power station to coordinate the phased array. In several embodiments, determinations of the relative locations of the antennas in the array are utilized to evaluate the phase shift and/or amplitude modulation to apply the reference signal at each power transmitter.

There is disclosed a radiation stable shield for use in space or high altitude applications. The shield comprises a plurality of overlapping planar glass flakes which are held in a lamellar matrix of flexible polymeric material. The flakes are each formed of a radiation stable glass which is suitable for use in space or high altitude applications. The flakes are arranged in alignment with the lamellar direction of the matrix.
摘要:
The present invention prevents occurrence of electrical discharge on an electrically conductive structure in an environment in which high-energy electrons impinge onto the structure or on an electronic element mounted to a surface of the structure, which electrical discharge would otherwise occur when the potential of the structure or the electronic element increases in the negative direction due to a negative charge flowing thereinto. An insulating tape bonded to the surface of the electrically conductive structure is partially cut-removed; an electrically conductive adhesive is applied to an exposed portion of the surface of the electrically conductive structure; and an insulating film is bonded to the electrically conductive adhesive, such that the electrically conductive adhesive is exposed to the outside. When encountering higher-energy electrons, the insulating film is charged, so that a strong electric field is applied to the electrically conductive adhesive, and electrons are emitted from the electrically conductive adhesive through field electron emission, to thereby prevent the potential of the electrically conductive structure from increasing in the negative direction.

A substrate structure for lightweight, flexible solar cell arrays, in which a plastic substrate is provided with a structure for discharging accumulations of electrons on its rear face and has appropriate heat emmissivity properties. In one embodiment, a Kapton substrate layer is coated with a grounded aluminum layer, which is suitably painted for emissivity. In another embodiment, a poorly conductive Kapton substrate layer, impregnated with carbon, is used to dissipate the charge, and to provide the appropriate emissivity. In a third embodiment, a grounded VDA layer is sandwiched between two Kapton layers.
