Abstract: Aircraft-vision systems and methods for maintaining situational awareness and spatial orientation are described. In one aspect, a holographic image with visual cues is projected into a peripheral area—from the pilot's perspective—of an aircraft cockpit, such that visual cues stimulate the pilot's peripheral vision. These visual cues help the pilot to maintain spatial orientation in visually deficient flight conditions without increasing pilot workload.

Abstract: A system and method for minimizing or eliminating Coriolis-tumbling sensations on a trainee in a centrifuge-based simulator is described. In one example methodology, a simulator transitions its rate of rotation to replicate flight conditions in which G-forces are unloaded on a trainee from a first-G-force value to a nominal-G-force value. Before reaching the nominal-G-force value, an intermediate-G-force value—which is more than the nominal-G-force value, but less than the first-G-force value—is imparted and maintained on the trainee for a suitable duration of time. This intermediate-G-force value may be determined based on several factors including: (i) the angle of rotation of a gondola at during the first-G-force value, and/or (ii) the first-G-force value. After the intermediate-G-force value is imparted and maintained for a suitable duration of time, the G-forces imparted on the trainee may be further unloaded till the nominal-G force value is reached.

Abstract: In a lighting apparatus comprising a light source housing is pivoted on a clip that can attach alternatively to a head strap adapter or to an adapter secured to a night vision goggle mounting plate. The clip includes a horizontal member having a bracket on the light source housing is rotatable, a pair of spaced, upwardly extending, tabs, and a vertical member extending upward from a location between the tabs. The upwardly extending tabs enter slots on the bottom of the adapter or mounting base, and a rib on the top of the adapter or mounting base is received by a snap fit in a downwardly facing slot on a horizontal part at the upper end of the vertical member of the clip.

Abstract: A method of improving natural gas release from a well via an enhanced hydraulic fracturing operation. The method includes capturing or retrieving the flow back from the well following the fracturing operation. The flow back or other source water is introduced to an electrocoagulation (“EC”) treatment process. EC treatment separates the water from other fracturing fluid components in the flow back and also removes bacteria and other contaminants. Thereafter, the EC-treated fluid is recycled for subsequent fracturing operations. The process may also be used to treat all source water, including fresh water delivered to the well before it is used as a fracturing fluid.

Abstract: An electronic currency and authentication system and method. An electronic money validator is attached to electronic money. The electronic money validator authenticates the electronic money originated by electronic money issuer. The electronic money might be originated when cash or cash equivalent is received from a customer for deposit into the customer's account. The electronic money validator is retired when the electronic money is removed from circulation.

Abstract: A hyperbaric apparatus with storage compartment is provided comprising a chamber for housing a patient and administration of hyperbaric therapy, a moveable patient support platform for receiving the patient and for transferring the patient into and/or out of the chamber, and a base comprising a storage compartment for stowing a patient transport device. The storage compartment conveniently stows the patient transport device, excluding it from the space surrounding the hyperbaric chamber, thereby freeing-up floor space surrounding the hyperbaric treatment area, while keeping the transport device close-at-hand for removal of the patient upon the conclusion of hyperbaric treatment.

Abstract: A modular concrete unit for load-bearing surfaces, and a concrete assembly having at least two modular concrete units connected by a hinging attachment. The modular unit has a top surface, a bottom surface, and at least three side walls extending between the top and bottom surfaces. The side walls of each modular unit include at least one engagement means configured for hinging attachment to a neighboring modular unit. The concrete assembly made from at least two modular units further includes at least one hinge pin connecting the engagement means of a first concrete unit and the engagement means of a second concrete unit.

Abstract: A process for providing upset recovery training (URT) includes using a sustained-G multi-axis platform (e.g., a centrifuge-based simulator). Various embodiments of the present invention address an important aspect of URT that is not present in the prior art, namely the placing of physiological stresses on the trainees during URT, such as sustained motions including, but not limited to, sustained, elevated G-forces and continuous rotational cues. Elevated, sustained, G-forces and continuous rotational cues can create many physiological challenges to aircrew. These challenges can include motion discomfort, disorientation, and visual disturbances. Embodiments of the present invention provide URT that includes physiological stresses on the pilot. If a pilot learns the correct procedures for recovery from an upset, as in the prior art URT programs, but cannot execute the procedures in the real world because he or she has not been prepared for the physiological environment to be faced, then safety is compromised.

Abstract: A low profile lighting apparatus is characterized by a battery housing, a rail-engaging plate connected to the housing by a pair of arms, and a recessed activating push-button located between the arms and adjacent the rail-engaging plate. A flexible resilient tab, also recessed between the arms, secures the apparatus to a rail. A lock-out switch is built into a plug for closing an end of the housing. The plug has three discrete rotational positions, one for attachment, a second for activation of an illumination source, and a third for preventing accidental activation of the illumination source by requiring simultaneous axial pressure and rotation. Instead of the plug, a hinged door having a sliding latch part can be utilized. The sliding latch part includes a pair of resilient legs that cooperate with surfaces inside the door to urge the latch part toward a latching condition.

Abstract: A method of improving electrocoagulation (“EC”) treatment processes for treating waste water and similar applications. The method includes providing a variable power supply that outputs an alternating current (“AC”) to one or more EC treatment cells. The alternating current from the variable power supply is rectified before delivery to the EC cell. As an intermediate step between the variable power supply and rectification, the method described and claimed here uses a variable step down transformer to modify the output delivered to the EC cell.

Abstract: Some implementations include a method for operating a centrifuge-based-flight simulator in at least one of several different modes: a heightened G-force mode, a normal G-force mode; and transition modes (i.e., ramp-up or ramp-down modes) between the heightened G-force and normal G-force modes. During the normal-G-force mode the simulator ceases planetary motion altogether or substantially decreases rotations to replicate a plurality of flight conditions that physically imparts, on the trainee during operation of the simulator, a G-force that is not greater than approximately one (1) G. The reduction of planetary motion while maintaining realistic motion and force sensations that are appropriate for the virtual-flight conditions being experienced allows realistic flight simulation experience for the trainee and reduces the negative effects of constant planetary motion.

Abstract: In an adjustable light, a mounting base is formed with a pair of arcuate slots for receiving hooks protruding from a light module. For attachment of the light module to the base, the hooks enter open ends of the respective slots, and the light module is rotated to engage the hooks with the slots. A sheet of spring metal with two series of protrusions is sandwiched between a rear part of the base and a front part in which the slots are formed. The protrusions are exposed through the slots, and a space is provided behind the protrusions, allowing them to move resiliently when engaged by the hooks as the light module is rotated so that the light module can be retained in any selected one of a plurality of angular positions.
