Abstract: A system and method for growing and maintaining biological material including producing a protein associated with the tissue, selecting cells associated with the tissue, expanding the cells, creating at least one tissue bio-ink including the expanded cells, printing the at least one tissue bio-ink in at least one tissue growth medium mixture, growing the tissue from the printed at least one tissue bio-ink, and maintaining viability of the tissue.

Abstract: A tapered box that is buried in the ground with a removable lid that is used to anchor baseball bases in place but also allows for them to be easily removed when the playing surface is being groomed. This novel system eliminates the problems created when soil accidentally falls into the present art anchoring systems. Additionally no concrete is needed to hold the anchor in place; non-corrosive materials are used to eliminate rusting parts from adhering to one another and, because the lid is made of a rubberized material it has shock absorbing properties to help prevent injuries.

Abstract: An escape hatch for use with an enclosure such as a tractor trailer is disclosed. The escape hatch comprises an opening defined by the body of the enclosure and a door that is secured to opening by an opening mechanism and a latch mechanism. The escape hatch prevents people from becoming trapped in an enclosure and provides a safe route of escape should a person inadvertently be locked in the enclosure.

Abstract: A system of locking a door is disclosed. The system according to the present invention comprises a releasable keeper that secures a door locking mechanism to keep a door secured to an enclosure in a locked position. A release mechanism that is operated from the interior of the enclosure releases the releasable keeper from the enclosure and enable the door to be opened and prevents people from becoming trapped within the enclosure by a locked door. In an exemplary embodiment, the release mechanism is operated by a lever that operates a pulley system to disengage the release mechanism from the releasable keeper.

Abstract: An integrated system for providing 3-axis attitude-control, energy-storage, and electrical power in which two counter-rotating inertia-wheels are tandem mounted with rotational axis oriented on and parallel to the longitudinal-axis of an airframe. A horizontal- and vertical-translating support is centrally-located between the wheels and houses a common wheel-bearing mount communicating with and supporting both inward-pointing inertia-wheel shafts. The preferred embodiment further consists of two outwardly-mounted tilt wheel bearing and suspension means, each communicating with and supporting an inertia-wheel outward-pointing shaft. Taken together, these supports and their associated two-axis actuator enable both wheels to be tilted equally in opposite directions to generate a combination of pitch and yaw reaction torque. Further, an electric generator integrally mounted to each inertia-wheel, and an electric load controller connected to each electric generator enable the creation of reaction roll torque.

Abstract: A pneumatic/mechanical actuator described herein consists of a variation of a Brayton-cycle machine for generating actuation force. The system avoids the continues heat problem of a Brayton-cycle by using compressed gas to drive a reversible turbine. The turbine only is driven when a change of actuation position. The system includes an internal-combustion engine-air compressor, a pneumatic energy storage and transfer system, a fuel/air mixing means, two electric pilot valves, two lean-ratio high-pressure catalytic-bed burners, a small-diameter and reversible turbine, a ratio speed-reducing transmission, an optical-encoder feedback position and speed sensor and a ball-screw push-rod mechanism. An alternative embodiment uses a free piston engine compressor hybrid to provide the compressed air. Manual or computer control may be used to monitor and direct desired changes in actuator position.
