    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: A night vision system along with an image intensifier tube and method for forming the tube are provided. The night vision system incorporates the image intensifier tube in both an analog channel as well as a digital channel, with an addressable display within the analog image intensifier tube analog channel configured to create an electronically addressable output. An analog image intensifier tube is included in the digital imager for presenting binary digital signals representative of an image, or of symbol indicia, and registering those digital representation from the digital imager onto one or more electron multipliers of the analog image intensifier tube within the analog channel. The provided night vision system also utilizes a cathodoluminescent screen, which is a highly efficient light source that reduces system power.

    Abstract: A night vision system along with an image intensifier tube and method for shuttering the continued draw of electrons from an electron multiplier are provided. The night vision system includes the electron multiplier, or possibly two electron multipliers, each comprising a silicon membrane. A shutter voltage is applied between a first surface and a substantially parallel, opposed second surface of the silicon membrane to discontinue draw of electrons through the electron multiplier and for substantially discontinuing display of an image from the image intensifier tube under certain bright light conditions. Utilizing a global shutter control on the electron multiplier, and the significantly lower voltage for such control mitigates power consumption within the image intensifier, as well as electromagnetic interference and delay response time. A relatively low voltage negative bias shutter voltage on only the electron multiplier selectively provides global shutter to the image intensifier device.

    Abstract: 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.

    Abstract: A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.

    Abstract: 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.

    Abstract: 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.
