David E Acker, Ian McNulty, Robert C Pacheco, Wayne Grandner: Magnetic determination of position and orientation. Biosense, Lerner David Littenberg Krumholz & Mentlik, September 24, 1996: US05558091 (629 worldwide citation)

A magnetic position and orientation determining system uses magnetic fields, desirably including uniform fields from Helmholtz coils positioned on opposite sides of a sensing volume and gradient fields generated by the same coils. By monitoring field components detected at the probes during applicat ...

Ian McNulty: Use of a focusing vortex lens as the objective in spiral phase contrast microscopy. U Chicago Argonne, Joan Pennington, January 4, 2011: US07864415 (1 worldwide citation)

A method and objective apparatus are provided for implementing an enhanced phase contrast microscope. A focusing vortex lens, defined by a diffractive spiral zone plate (SZP) lens, is used for the objective for the phase contrast microscope. The SZP lens focuses and imparts a helical phase to incide ...
