Abstract: A counter momentum generator is employed on a weapon system to manage horizontal recoil momentum of the weapon system. The counter momentum generator generates a counter momentum which that is not parallel to the recoil momentum. A horizontal component of the counter momentum negates a portion of the horizontal recoil momentum. A vertical component of the counter momentum combines with the vertical recoil momentum to aid in compression between the base of the weapon system and the ground.

It provides a mechanism for prioritizing data collection and analysis efforts.

Abstract: Ready armor modular protective systems that can be rapidly deployed in an urban environment. Exemplary armor systems include multiple space frame units. Adjacent space frame units can be coupled together with vertically adjustable coupling mechanisms. Coupling mechanisms (e.g. slot and pin connecting mechanisms) can facilitate relative displacement between adjacent space frame units when the units are connected. In this way, a wall of connected adjacent space frame units can be placed and/or moved along an uneven or irregular surface (e.g. having bumps or a grade) and the adjacent space frame units can remain in parallel and/or vertical orientation relative to one another. Suspension mechanisms can help to facilitate or enable rapid deployment of a ready armor modular protective system.

Abstract: An apparatus for passive sampling of airborne particles such as those found in an aerosol is disclosed. The passive sampler is designed to take advantage of natural air flow to collect airborne particles, such as those contained in an aerosol, for subsequent analysis. The passive sampler increases the sampling efficiency for diffusion and electrostatic collection of particles by using natural airflow or movement to bring particles closer to the deposition surface. Alternately charged electret filters further increase the sampling efficiency.

Abstract: Detecting the occurrence of loss of effective lubrication in high-speed machinery components is provided. The imminent catastrophic failure may be predicted when torque or power transfer is lost. An estimate of when failure will likely occur throughout the operation of the machinery may be determined as well as the damage state after the liquid lubrication supply has ended or becomes inadequate to lubricate the machinery components effectively. By monitoring the concentration of gas species and the rate of change in concentration of the gas in the gearbox or machinery enclosure after the supply of the primary lubricant ends, determinations may be made about the time to failure and the damage state. The determinations may be based on thermomechanical and chemical processes, on measurement of a baseline system, or by setting a threshold of expected change in gas concentration. These determinations may be transmitted for further decision making and response.

Abstract: A biplaner rotor blade has an upper airfoil section connected to a lower airfoil section such that the upper airfoil and lower airfoil are rotated in separate planes—an upper plane and a lower plane. The upper airfoil has a root end attached to a hub at an upper location of the hub and the lower airfoil has a root end attached to the hub at a lower location of the hub. The upper airfoil converges with the lower airfoil to form a blade tip end at the outermost portion of the blade, thus generating lift along two geometric planes.

Abstract: An image rendering system comprising a pixel array and variable-density column and row scanner circuits is disclosed. The variable-density column and row scanner circuits enable software-based reconfiguration of the active display area within the available screen area of the display. In addition, a hardware restore-to-black function is provided that enables pixels outside of the desired image region to be driven to black without their requiring image data or excitation. As a result, the functionality of the functionality of the display can be reconfigured to match the desired image region on a frame-by-frame basis. Therefore, displays in accordance with the present invention can operate at higher frame rates and with less power consumption that prior-art displays.

Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof.
