Abstract: Embodiments of the invention are directed to a 3D printing system that directs projected light at tunable wavelengths to cure a polymer resin from monomers or oligomers which floats on a dense liquid platform in which the curing occurs within a prepackaged vessel which facilitates the layer is printed at any given time.

Abstract: Embodiments of the invention is directed to a manufacturing process to mold and cast custom softening polymers into complex shaped devices, said process comprising the steps of: creating a 3D mold or shell; injecting the shell with a polymer or pre-polymer; cooling or curing the polymer in a short period of time; and forming a device.

Abstract: A system is provided for training a golf club stroke. The system includes a sensor, and a transmitter positioned in a spaced relation to the sensor, where the transmitter transmits a signal received by the. The system further includes a golf club including a head including a transparent medium region, where the head is positioned between the sensor and the transmitter. The signal passes through the transparent medium region.

Abstract: A system for cleaning and sanitizing a food preparation area is provided. The system includes a retractable hose device, including a hose and a device for retracting the hose, and a fluid directing nozzle connected to the hose. A proportioning device is connected to the hose which includes a first input for receiving one or more of a cleaning agent and a sanitizing agent, and a second input for connection to a supply of diluent.

Abstract: An improved crystal plating device having a base containing a power circuit and an oscillating circuit. The base is provided with a chamber and has a sealed top enclosing the chamber. At least one pair of filament posts are fixed to the base and disposed within the chamber and in the power circuit. A filament is connected across the filament post. A crystal holder is removably connected with the base. The crystal is held by the holder in the oscillating circuit. A pump is connected to the base to vacuum pump the chamber. Energizing the circuits will oscillate the crystal and evaporate the filament to plate the crystal and produce the desired frequency therefore. The improvement comprises a crystal holder designed to hold a plug-in circuit board having a plurality of prongs, the board containing the crystal. The crystal holder includes plug-in means for inserting the prongs of the circuit board in the oscillating circuit.
