Abstract: A glycerin separation system heats a mixture of glycerin to about 231 degrees Fahrenheit and then allows the mixture to rest in a settling tank. Over time the mixture separates into layers of differing densities. The layers are removed individually by measuring the density of the exiting fluid. The glycerin is heating in a loop to allow for precise control of the temperature of the mixture. The pH is also controlled with a preferable level of 5.

Abstract: In one implementation, a computer-implemented method includes accessing, by a computing device, a real-time three dimensional (“3D”) image of at least a portion of a user who is standing in front a surface; identifying, by the computing device, coordinates in 3D space for at least one appendage of the user from the 3D image; determining, by the computing device, a position of the at least one appendage of the user over the surface based on the coordinates of the at least one appendage in 3D space; determining whether the position of the appendage is within one or more active areas of the surface; and based on the determination of whether the appendage is within the one or more active areas of the surface, updating a visual image that is being projected onto the surface by a projector that is located above the surface.

Abstract: The present invention provides an improved material dispenser which allows adjusting of the handle portion of the dispenser relative to the material being dispensed, allowing a user to achieve a more-or-less constant planar relationship between the material and the object being wrapped. Further, the present invention provides a means of securing the loose end of the material to the handle of the dispenser.

Abstract: An interface device for connection between a facsimile reproduction machine and a simplex radio includes a receiving circuit and a transmitting circuit. A switch connects an appropriate one of the circuits to the machine. A control circuit monitors the change in the mode of operation of the machine and operates upon the switch to cause a corresponding change of connection to the machine. The control circuit also operates upon the transceiver to condition it to a transmit mode upon the transmit circuit being selected.
