Publication number: 20130233300Abstract: A solar energy collection system includes a reflector configured to reflect and focus a majority of solar energy from visible light and infrared spectra. The solar energy collection system also includes a light trap configured to receive concentrated solar energy from the reflector. The light trap includes a black body that is configured to absorb a majority of the concentrated visible light and infrared energy and convert the absorbed energy into thermal energy.Type: ApplicationFiled: March 9, 2012Publication date: September 12, 2013Inventor: Virgil Dewitt Perryman

Patent number: 8011361Abstract: A tower type heat dissipating structure is applied to dissipate the heat of a solar power system. The solar power system is provided with a reflector having a hemispheric surface for reflecting the sunlight to a solar cell. The heat dissipating structure comprises a heat-conducting plate, a plate type heat pipe and a plurality of heat dissipating fins. One side of the heat-conducting plate is connected with the solar cell, and the other side is provided with a groove for being embedded an end of the plate type heat pipe. The heat dissipating fins is arranged with an inclination angle against the plate type heat pipe that can promote the heated air within the gaps to rise. The heat is rapidly conduced to prevent the solar cell from being destroyed by overheating for reducing the repairing costs.Type: GrantFiled: March 26, 2009Date of Patent: September 6, 2011Assignee: Celsia Technologies Taiwan, Inc.Inventors: George Anthony Meyer, IV, Chien-Hung Sun, Chieh-Ping Chen

Patent number: 7946287Abstract: Solar concentrator system(s) that include parabolic Total Reflection Reflectors with corrected Curved Rectangular Total Reflection Prisms are provided. The corrected Curved Rectangular Total Reflection Prisms remove optical imperfections of diffusion typically present at conventional rectangular prisms of conventional parabolic and paraboloid TRR, and enable accurate focusing and high concentration ratios. A variation of the corrected Curved Rectangular Total Reflection Prisms allows the construction of a corrected solar wave guide with total reflection walls (Solar Artery), which enables the removal of the diffusion (and losses) typically present at conventional Hollow Solar Wave Guides, and increase by one or more orders of magnitude the light-propagation range of Solar Arteries for the same level of losses.Type: GrantFiled: April 2, 2004Date of Patent: May 24, 2011Inventor: Alexandros Papadopoulos

Patent number: 7550054Abstract: A method of manufacturing a mirror for a dish reflector of a system for generating electrical power from solar radiation is disclosed. The method includes the steps of: (a) shaping a blank of a deformable material to have a concave surface that is a required surface profile for a mirror; and (b) glueing, laminating or otherwise adhering together a back surface of a sheet of reflective glass and the concave surface of the shaped blank to form the mirror.Type: GrantFiled: March 28, 2002Date of Patent: June 23, 2009Assignee: Solar Systems Pty Ltd.Inventor: John Beavis Lasich

Patent number: 5979438Abstract: A sunlight collecting system comprises an oval mirror 1 directed downwardly and provided at a given elevation, and a plurality of heliostats 5 arranged on the ground about the oval mirror 1, each heliostat having a concave mirror 13 for reflecting and converging sunlight L onto the oval mirror 1. The sunlight L reflected on the concave mirror 13 of each heliostat 5 is focused to a point at a first focal point of the oval mirror 1, and converged to a second focal point of the oval mirror 1 after reflected by the oval mirror 1.Type: GrantFiled: June 3, 1998Date of Patent: November 9, 1999Assignee: Mitaka Kohki Co., Ltd.Inventor: Katsushige Nakamura

Patent number: 5971551Abstract: A nonimaging concentrator (or illuminator) of light. The concentrator (or illuminator) has a shape defined by dR/d.phi.=Rtan.alpha. where R is a radius vetor from an origin to a point of reflection of a light edge ray from a reflector surface and .phi. is an angle between the R vector and an exit aperture external point of the concentrator (illuminator) and coordinates (R, .phi.) represent a point on a reflector curve and .alpha. is an angle the light edge ray from an origin point makes with a normal to the reflector curve. The reflector surface allows the light edge ray on the reflector curve to vary as a function of position. In the concentrator an absorber has a shape variable which varies with position along the absorber surface.Type: GrantFiled: July 7, 1995Date of Patent: October 26, 1999Assignee: ARCH Development CorporationInventors: Roland Winston, David Gerard Jenkins

Patent number: 5680867Abstract: In an electronic blood pressure measurement device which is arranged to extract pulse waves from the measured cuff pressure, a pulse wave pattern is generated from the pulse wave amplitude and pulse wave interval data and this pulse wave pattern is compared with reference patterns to classify the pattern in order to accurately obtain biological information other than the blood pressure. Blood pressure amplitudes PA(i) are computed from the measured cuff pressures C(i) and a pulse wave pattern is generated (35) on the basis of this pulse wave amplitude data and this pulse wave pattern is classified into a plurality of reference patterns (37) according to reference patterns or reference values (36). Here, the reference patterns or reference values are set as hemodynamic references based on dynamic characteristics of the blood vessel or cardiac output characteristics.Type: GrantFiled: February 13, 1995Date of Patent: October 28, 1997Inventors: Hideaki Shimazu, Hidetaka Shimizu, Noriyuki Yamaguchi, Masaru Komatsu
