Patent number: 10509091Abstract: Various systems and methods for detecting electron spins using electron paramagnetic resonance are described. An excitation signal generator configured to generate an excitation signal of varying amplitude and phase as compared to a reference signal may be present. A crossed-loop resonator configured to isolate a detection signal produced by the excitation signal exciting an object with a magnetic field may also be present. Further, a detection device configured to detect electron spins of the object using the detection signal isolated by the crossed-loop resonator may be present.Type: GrantFiled: March 7, 2013Date of Patent: December 17, 2019Assignee: Colorado Seminary, which owns and operates the University of DenverInventors: Mark Tseitlin, Richard Quine, George Rinard, Gareth Eaton, Sandra Eaton

Patent number: 10502797Abstract: Embodiments of the invention are directed toward a crossed-loop electron paramagnetic resonance resonator comprising a first resonator having a first resonator axis; and a second resonator having a second resonator axis. The first resonator axis and the second resonator axis can be substantially perpendicular. Either or both the first resonator and the second resonator can be a ribbon resonator having a plurality of metallic ribbons formed in a loop. Each metallic ribbon can include a central axis. The plurality of metallic ribbons can be arranged parallel relative one to another.Type: GrantFiled: July 19, 2013Date of Patent: December 10, 2019Assignee: Colorado Seminary, Which owns and operates the University of DenverInventors: George Rinard, Gareth Eaton

Patent number: 6046586Abstract: A resonator structure including a first resonator having a first resonator loop formed by a hollow channel with conductive walls and a second resonator having a second resonator loop formed by a hollow channel with conductive walls. The first resonator loop and the second resonator loop intersect so that the first and second resonator loops are substantially shielded to prevent coupling of high frequency energy between the first and second resonator loops. The orthogonally of the resonator loops can be adjustably control in either of two orthogonal axes. A sample is placed in a space defined by the intersection of the first and second resonator loops. High frequency energy is applied to the first resonator. The angle at which the second resonator loop intersects the first resonator loop is selected to substantially decouple the first resonator from the second resonator. A detector circuit detects the high frequency energy in the second resonator loop and supplies the detected signal for subsequent analysis.Type: GrantFiled: April 13, 1998Date of Patent: April 4, 2000Assignee: Colorado SeminaryInventor: George A.

Patent number: 4431434Abstract: An improved electrostatic precipitator for removing high resistivity particles from a gas stream. The precipitator includes a charger section having a plurality of corona electrodes and hollow tubular collector electrodes. These electrodes are arranged in parallel, alternating arrangement in a single plane which is positioned perpendicular to the gas flow. The electrodes are connected to a high voltage electrical source while produces a thin high current electrical field which electrically charges the particles present. A temperature control fluid is passed through the collector electrodes to control the temperature of the particles collected so as to maintain the resistivity of the particles in a range in which back ionization will not occur. Due to the size and geometry of the charger section and the temperature control of the particle layer, an extremely high voltage, high current electrical field can be maintained. A collector section can be provided spaced downstream from the charging section.Type: GrantFiled: March 6, 1981Date of Patent: February 14, 1984Assignee: University of Denver, Colorado SeminaryInventors: George A.

Patent number: 4270547Abstract: A system is disclosed for monitoring vital physiological signs. Each of the system components utilizes a single hybrid circuit with each component having high accuracy without the necessity of repeated calibration. The system also has low power requirements, provides a digital display, and is of sufficiently small size to be incorporated into a hand-carried case for portable use. Components of the system may also provide independent outputs making the component useful, of itself, for monitoring one or more vital signs. The overall system preferably includes an ECG amplifier and cardiotachometer signal conditioner unit, an impedance pneumograph and respiration rate signal conditioner unit, a heart/breath rate processor unit, a temperature monitoring unit, a selector switch, a clock unit, and an LCD driver unit and associated LCDs, with the system being capable of being expanded as needed or desired, such as, for example, by addition of a systolic/diastolic blood pressure unit.Type: GrantFiled: October 3, 1978Date of Patent: June 2, 1981Assignee: University Patents, Inc.Inventors: Dale A.

Patent number: 4145122Abstract: This invention relates to an apparatus for monitoring the position of the eye and generating an electrical signal based upon its displacement from a neutral position, such apparatus being characterized by a pair of eyeglasses modified to provide an infrared mirror on the inside surface of one lens, an infrared light emitting diode located on the nosepiece in position to produce a virtual image thereof within the wearer's eye as reflected from the infrared mirror, and an image detector mounted on the bow of the eyeglasses adjacent the mirror filtered to respond only to infrared light and effective to locate the position within the eye of the reflected LED image. The invention also encompasses a novel detector which, not only monitors the position of the eye but, in addition, through the use of a photosensor array, provides the means for generating a signal whose magnitude is proportional to the displacement of the eye from its centered or reference position.Type: GrantFiled: May 31, 1977Date of Patent: March 20, 1979Assignee: Colorado SeminaryInventors: George A.
