Patents by Inventor Jason Alan Schaefer

Jason Alan Schaefer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7440192
    Abstract: A system to produce orthogonal beams includes a laser diode operating in conjunction with a collimating lens, with or without an aperture, and a simple compact optic. At least one collimated beam is directed toward an optic comprised of components that are bonded together. Beams are reflected from at least one optical components at right angles to produce a plumb beam. Additionally, a beam is reflected from the optic at a right angle, as well as transmitted through the optic, to produce square and level beams. All beams are orthogonal to each other, have relatively equal power, and are aligned and oriented so as to appear to be originating from a coincident point. An optional orthogonal beam may be produced. An optic in the shape of a cuboid comprised of six small components is also disclosed.

  • Patent number: 7092167
    Abstract: A system to produce orthogonal beams includes a laser diode operating in conjunction with a collimating lens, an aperture, and a simple compact optic. Three collimated beams are directed toward an optic comprised of components that are bonded together. Beams are reflected from two optical components at right angles to produce plumb beams. Additionally, a beam is reflected from the optic at a right angle, as well as transmitted through the optic, to produce square and level beams. All four beams are orthogonal to each other, have relatively equal power, and are aligned and oriented so as to appear to be originating from a coincident point. Optionally, a fifth orthogonal beam may be produced. An optic in the shape of a cuboid comprised of six small components is also disclosed.
