Abstract: A motorized leveling stage capable of adjusting the angular position of a work piece relative to a reference plane includes an upper stage, a lower stage, and a hinge coupling corresponding edges of the two stages together for relative pivotal movement of the stages. A first spring pivotally biases the upper and lower stages toward each other about the axis of the hinge. A slide is disposed for sliding movement on an upper surface of the lower stage in a direction generally perpendicular to the hinge axis. The slide includes an upper surface defining an inclined plane disposed in sliding abutment with a lower surface of the upper stage such that movement of the slide toward and away from the hinge respectively raises and lowers the upper stage relative to the lower stage. A motorized drive assembly is operable to control movement of the slide relative to the hinge.

Abstract: Methods and systems for mitigating undesirable video flash in infrared camera systems are disclosed. A frame of video can be stored in a buffer and information related to the frame of video can be processed prior to displaying the video such that the processed information facilitates display of the video substantially without flashing. A display of a non-flashed frame can be frozen while a flash event would otherwise cause a flashed frame to be displayed. The shift in a histogram caused by a flash event or some portion thereof can be subtracted from pixels of an image. Thus, image quality can be substantially enhanced.

Abstract: Systems and methods for providing a sealed container having a reduced pressure atmosphere are disclosed. The container is suitable for housing an infrared detector array. Outgassing can be enhanced by adding features to solder preforms that maintain pathways for gasses to more readily exit the container prior to sealing thereof. Getters can be used to mitigate undesirable gases within the sealed container. One or more bolometers can be used to determine if the sealed container is leaking. A vacuum positioning fixture can be used to assemble the components of the infrared detector assembly and to place the infrared detector assemblies into a vacuum chamber. The cost of manufacturing such infrared detector assemblies may be reduced and the reliability thereof enhanced.

Abstract: A device for associating a circuit breaker with a circuit may have one or more sensors for remotely sensing that a circuit is active. When a sensor senses that a circuit is active, a transmitter may transmit a signal to a receiver that alerts a user. In this manner, the user may determine which of a plurality of different circuit breakers is associated with a particular circuit. This device mitigates the contemporary need to repeatedly turn off circuit breakers, go to the room in which the circuit is being monitored, and check to see if the circuit is active.

Abstract: The present invention relates to a device package, such as an electronic system package, that is suitable for use in harsh military or commercial environments. The package components, including a base enclosure and mating cover, comprise a series of interconnected electrically conductive materials, forming a tortuous electrically conductive path, that advantageously shield electromagnetic interference (“EMI”). The electrically conductive, EMI-shielding layers and other coated layers (e.g., insulative electrocoated paint layers) are smooth layers that provide corrosion resistance to the interior and exterior surfaces of the package. The package is also designed such that its components form a water tight seal. Thus, innovatively, the package comprises a combination of components that synergistically shield electromagnetic interference, resist interior and exterior corrosion, and form a water tight seal. The package is configured to pass military specification EMI and salt fog standard testing.

Another imager sensitive to infrared radiation at least 3-microns in wavelength may be used to produce a second image signal. Preferably, the first image signal represents sensed electric light sources, and the second image signal represents sensed background such as terrain, runways, structures, and obstacles. A signal processor combines an image signal representing locally maximum values of the first image signal with the second image signal to create a displayed image.

A layer of metal is deposited over the patterned layer of photoresist, the metal layer includes metal feature portions in the metal feature areas, residual metal areas in the residual metal areas, and residual metal flaps at the edges of the metal feature portions. The wafer is sprayed with high-pressure solvent at a pressure to dissolve the layer of photoresist and to physically remove the residual metal portions from the residual metal areas, leaving only at least a portion of the residual metal flaps. The wafer is sprayed with a stream of frozen gas particles to remove the residual metal flaps.
