Abstract: Techniques are disclosed for systems and methods using infrared imaging modules to image and detect phase transitions of water, such as ice formation, in a scene. An ice formation detection system may include one or more infrared imaging modules, a logic device, and a communication module. The infrared imaging modules may be positioned to image a scene in which ice formation is to be detected. The logic device may be adapted to process captured infrared images to detect ice formation in the scene. The logic device may also be adapted to use the communication module to report detected ice formation to an indicator, a display, a user interface, and/or an ice formation mitigation system.

Abstract: Binocular system, including method and apparatus, for viewing a scene. The system may comprise a left camera and a right camera that create left and right video signals from detected optical radiation. At least one of the cameras may include a sensor that is sensitive to infrared radiation. The system also may comprise a left display and a right display arranged to be viewed by a pair of eyes. The left and right displays may be configured to present respective left video images and right video images formed with visible light based respectively on the left and right video signals.

Abstract: A track saw system including a track having a pair of longitudinally-elongated rails extending along its top surface. Each rail has an angled sidewall extending from the top of the track at an angle of 45 degrees. The system further includes a base plate adapter having a pair of grooves formed in its bottom surface that are similar in size, shape, and relative position to the rails. The distance between the angled walls of the grooves is shorter than the distance between the angled walls of the rails. The rails of the track thus fit within the grooves of the base plate adapter with the angled sidewalls of the rails flatly engaging the angled sidewalls of the grooves. A firm, non-binding fit is thereby maintained between the track and the base plate adapter regardless of any expansion or contraction of the track that might occur due to variations in temperature.

Abstract: Apparatus and method for measuring the fluorescence of nanodrop liquid samples is described in which the sample is held by surface tension between two anvil surfaces. Each anvil surface has an embedded optical fiber with its end finished flush with the surface in the containment area wetted by the sample with the fiber in line. Sample excitation is provided from the side of the sample remote from the containment area. By selection of the fiber transmission numeric aperture the impact of exciting and ambient light on the measurement is minimized. A method of virtual filtering is taught in which any ambient or exciting light that does impinge on the measuring sensor is corrected by subtracting a scaled representation of the source from the measurement. The method and apparatus is capable of detecting 1 femptomole of sodium fluorescein in 1 microliter of TE buffer.

Abstract: A device that alters the breather hole configuration currently being employed in aircraft window assemblies. The device provides a means to allow slow moving air to pass and breathe through the breather hole, while stopping or significantly blocking non-steady air pulses from passing through. The device uses a combination of the cross-section and length of the air path that determines the effectiveness of the particular device to dampen out any unsteady airflow pulses.
