摘要： A method of controlling the performance of a night vision device includes supplying, by a power supply, to a microchannel plate of a light intensifier tube, a control voltage that controls a gain of the microchannel plate, determining an amount of compensation to apply to the control voltage based on a change to the control voltage attributed to a change in temperature of an operating environment of the night vision device, adjusting the control voltage in accordance with the amount of compensation to obtain a compensated control voltage, and supplying, by the power supply, the compensated control voltage to the microchannel plate of the light intensifier tube. The method may further include determining whether the night vision device has been used for a predetermined amount of time, and only after that predetermined amount of time, is the method configured to supply the compensated control voltage.

摘要： A landing zone designation system is provided that includes a master and a slave landing strobes. A detector on an aircraft can detect master and slave optical signals, and a processor can be coupled to the detector to compute placement of the aircraft relative to the master and slave landing strobes. A method is provided for designating a landing zone for an aircraft. The method includes emitting first and second optical signals, where a determination is made whether the aircraft is to land at a first landing zone or a second landing zone depending on a difference between the first optical signal and the second optical signal. A distance to landing within the determined first landing zone or the second landing zone can also be determined.

摘要： A landing strobe is provided having an optical emitter configured to emit an optical signal. An input device can be coupled to the optical emitter for setting the optical signal to a signature strobe output unique to the landing strobe. A landing zone designation system is also provided having a landing strobe configured to emit a signature strobe output unique to the landing strobe. An aircraft spaced from the landing strobe can include a detector for optically receiving the signature strobe output to determine the landing zone is proper to land the aircraft if the signature strobe output matches an expected signature strobe output.

摘要： A landing strobe is provided that comprises a vane extending from the landing strobe, and an actuator coupled to the vane. The actuator can be configured to move the vane from a first position to a second position upon impact of the landing strobe. The landing strobe can also comprise an optical emitter configured to emit an adjustable radiation pattern extending radially around a central axis that is substantially vertical when the van is moved to the second position. A landing strobe system is also provided and comprises a landing strobe configured to be released from an aircraft arranged over a landing zone. The vane is configured to extend at an upward angle outward from the landing strobe when released from the aircraft. The vane is further configured to extend at a downward angle outward from the landing strobe when the landing strobe contacts the landing zone.

摘要： A method of processing a double sided wafer of a microelectromechanical device includes spinning a resist onto a first side of a first wafer. The method further includes forming pathways within the resist to expose portions of the first side of the first wafer. The method also includes etching one or more depressions in the first side of the first wafer through the pathways, where each of the depressions have a planar surface and edges. Furthermore, the method includes depositing one or more adhesion metals over the resist such that the one or more adhesion metals are deposited within the depressions, and then removing the resist from the first wafer. The method finally includes depositing indium onto the adhesion metals deposited within the depressions and bonding a second wafer to the first wafer by compressing the indium between the second wafer and the first wafer.

摘要： A system. At least some embodiments are a system including a first processor and a non-volatile random access memory coupled to the first processor, the non-volatile random access memory storing program instructions for execution by the first processor in which the programming instructions are stored only in encrypted form. The system further includes an encryption engine coupled to the first processor and coupled to the non-volatile random access memory. A bridge logic device coupled is to the processor and configured to couple to an external peripheral network bus. The encryption engine is configured to decrypt software program instructions stored in the non-volatile random access memory for execution by the first processor.

摘要： A system includes a threat warning system and a countermeasure system. The threat warning system generates threat data that includes at least a threat coordinate value. The countermeasure system includes a wide-angle laser beam director and the infrared counter measure system that is configured to receive the threat data including the threat coordinate value from the threat warning system and causes the beam director to direct a divergent laser beam based on the threat coordinate value and cause the beam director to vary an angle of the cone based on an aircraft signature perceived by a threat.

摘要： A night vision system along with an image intensifier tube having a microchannel plate and method of forming the microchannel plate are provided. The microchannel plate comprises a plurality of spaced channels extending through the microchannel plate, wherein each channel sidewall surface near the input face of the microchannel plate comprises a series of layers formed thereon. The input face of the microchannel plate, as well as the sidewall surfaces of each channel near the input surfaces, are configured with an electron backscatter layer arranged between a contact metal layer and a secondary electron booster layer. When formed partially into the channel openings near the input face, the electron backscatter layer and overlying secondary electron booster layer are configured circumferentially around the sidewall surfaces and extend radially inward toward a central axis of each channel.

摘要： A night vision system, a microchannel plate (MCP), and a planetary deposition system and methodology are provided for selectively depositing an electrode contact metal on one side of MCP channel openings. One or more MCPs can be releasably secured to a face of a platter that rotates about its central platter axis. The rotating platter can be tilted on a rotating ring fixture surrounding an evaporative source of contact metal. Therefore, the rotating platter further rotates so that it orbits around the evaporative source of contact metal. A mask with a variable size mask opening is arranged between the rotating platter and the evaporative source. While the mask orbits around the evaporative source with the rotating platter, the mask does not rotate along its own axis as does the rotating platter.
