Abstract:
A method for data loading with a tablet includes receiving one or more software updates published by a ground station and storing the software updates on the tablet. The method also includes establishing communications between the tablet and a tablet interface module of an aircraft and determining if software on the aircraft needs to be updated. Based on determining that the software on the aircraft needs to be updated, the method includes transmitting at least one of the one or more software updates to the tablet interface module for loading into the aircraft and monitoring an installation process of the software updates in the aircraft via the tablet interface module.

A base (30) may also have an integrated heat pipe clamp attachment (100) forming an aperture in the base (30) into which a heat pipe may extend and may be clamped in thermal communication. The dissipation member (70) may be a series of fins and troughs and a fan (130) may direct air over the dissipation member (70) to cool the apparatus.
Abstract:
A sensor package (100; 100a; 100b) for sensing rotational positional data includes a stack of separated printed circuit boards that includes a first position target printed board (126), a second printed circuit board (120) having a rotary sensor and a third printed circuit board (140) having power supply components. The sensor package is included in a skew detection system (200) for an aircraft control system, which includes a control surface (210) having opposed first (210a) and second (210b) ends. A first drive mechanism (220a) is operatively connected to the first end of the control surface by a first rack and pinion assembly (230a) and a second drive mechanism (220b) is operatively connected to the second end of the control surface by a second rack and pinion assembly (230b). Each rack and pinion assembly includes a respective sensor package (100a, 100b) operatively connected to the pinion (234a, 234b) thereof. A processing component (240) is operatively connected to both sensor packages to determine presence of skew in the control surface.
Abstract:
A dual-mode, semi-active, laser-based and passive image-based seeker for projectiles, missiles, and other ordnance that persecute targets by detecting and tracking energy scattered from targets. The disclosed embodiments use a single digital imager having a single focal plane array sensor to sense data in both the image-based and laser-based modes of operation. A shuttering technique allows the relatively low frame-rate of the digital imager to detect, decode and localize in the imager's field-of-view a known pulse repetition frequency (PRF) from a known designator in the presence of ambient light and other confusing target designators, each having a different PRF.
Abstract:
A sensor (100) for monitoring external loads acting on a pin assembly includes a pin (24) having an axial interior bore defined therein and having a length defined from a first end to an opposed second end thereof. A core pin is mounted axially within the interior bore of the pin spaced radially inwardly from the interior bore for relative displacement with respect to the pin. A capacitor (108) is provided having an inner capacitor plate (118) mounted to the core pin (106), and an outer capacitor plate (114) mounted to the pin (24), such that relative displacement of the core and the pin (24) due to external loading on the pin (24) results in relative displacement of the inner and outer capacitor plates (118,114). The capacitor (108) is configured and adapted to be connected to an electrical circuit (110) to produce signals indicative of external loading on the pin based on relative displacement of the inner and outer capacitor plates (118,114).
Abstract:
A method to spread laser photon energy over separate pixels to improve the likelihood that the total sensing time of all the pixels together includes the laser pulse. The optical signal is spread over a number of pixels, N, on a converter array by means of various optical components. The N pixels are read out sequentially in time with each sub-interval short enough that the integration of background photons competing with the laser pulse is reduced. Likewise, the pixel read times may be staggered such that laser pulse energy will be detected by at least one pixel during the required pulse interval. The arrangement of the N pixels may be by converter array column, row, two dimensional array sub-window, or any combination of sub-windows depending on the optical path of the laser signal and the capability of the ROIC control.
