Patent number: 8168955Abstract: Locations of the origins of the photons are acquired from a scanned sample with reference to a scan frame. The location on the sample from which a photon was emitted is inferred from the location of the scan as commanded by a scan drive signal, a feedback signal related to the position of the scan device, or alternatively by the point in time during a scan at which the photon is detected. A position function, e.g., photon probability density, is associated with a photon position. Summing or other processing of photon probability density functions can require fewer photons to converge to an ideal density distribution associated with an image feature than are required using conventional pixel binning. Stored data can be mapped into pixels or voxels of a display or otherwise processed. Original data remains available in the digital storage for post-hoc analysis. Imprecision introduced by the display process need not adversely affect the precision of the collected data.Type: GrantFiled: May 9, 2011Date of Patent: May 1, 2012Assignee: Board of Regents of the Nevada System of Higher Education, on behalf of the University of Nevada, RenoInventors: John L. Sutko, Nelson G. Publicover

Patent number: 8031926Abstract: Locations of the origins of “discrete events,” e.g., photons or other units of radiant energy are acquired from a specimen with reference to a scan frame or other region of interest of the specimen. The location of origin of a discrete event can be determined from the corresponding location datum as derived from a scan-drive signal, a positional feed-back signal, or by a point in time during a unit of sampling time (“image-acquisition period”) at which the event is detected. A probability-density function (PDF) is associated with the detected locations. Summing or other processing of the PDFs is performed to produce imagable data. From the data, images can be produced that require fewer discrete events to converge to an ideal density distribution associated with an image feature than required by pixel-based binning methods. Stored data can be mapped into pixels or voxels of a display or otherwise processed, including post hoc processing.Type: GrantFiled: November 21, 2007Date of Patent: October 4, 2011Assignee: Board of Regents of the Nevada System of Higher Education, on behalf of the University of Nevada, RenoInventors: John L.

Patent number: 7796314Abstract: Dual axis, beam-steering devices are disclosed. An exemplary device includes a support platform having a top surface. A reflective surface is coupled to the top surface of the support platform. First and second galvanometers are coupled via respective linkages to the support platform such that the first galvanometer rotates the support platform about a first rotational axis, and the second galvanometer rotates the support platform about a second rotational axis that is orthogonal to the first rotational axis. The support platform can be simultaneously rotated with respect to both the first rotational axis and the second rotational axis to steer a beam of electromagnetic energy (e.g. light beam) reflected by the reflective surface.Type: GrantFiled: March 8, 2005Date of Patent: September 14, 2010Assignee: Board of Regents of the Nevada System of Higher EducationInventors: John L.

Patent number: 4440638Abstract: A device capable of manipulating, sorting, separating and measuring the properties of charged species particles by physical interaction via electrostatic forces. The device operates on charged species particles ranging from small molecular species to intact mammalian cells. The device has a semiconductor substrate serving as an electrode. A dielectric layer overlays the substrate. A chamber holds a fluid which contains the charged species particles. The fluid in the chamber is placed in physical contact with the dielectric layer. A control electrode of metal is disposed opposite the dielectric layer and is also in physical contact with the fluid. A voltage source establishes an electric field between the electrodes which extends into the liquid. Charged species particles are either attracted to or repelled from the dielectric layer surface. The device structure readily provides for precise and continuous control of the electric field at the dielectric layer-fluid boundary interface.Type: GrantFiled: February 16, 1982Date of Patent: April 3, 1984Assignee: U.T.
