Patent number: 9574092Abstract: Paint formulations having a high absorptivity with respect to solar radiation are disclosed herein. The disclosed paint formulations are also thermally and mechanically durable, thereby enabling the paint formulations to be used on components in solar thermal applications where exposure to high temperatures and environmental conditions may be an issue. The paint formulation can include an oxide-based pigment, an organic binder, one or more additives, an inorganic filler, and/or an organic solvent. The pigment can have a relatively high absorptivity with respect to light having a wavelength in the range from 250 nm to 3000 nm. Curing of the paint formulation can irreversibly convert the organic binder into an inorganic binder.Type: GrantFiled: April 17, 2012Date of Patent: February 21, 2017Assignee: BrightSource Industries (Israel), Ltd.Inventors: Shlomo Magdassi, Daniel Mandler, Mubeen Baidossi, Rachel Assa, Ophir Chernin, Yaniv Binyamin

Patent number: 8931475Abstract: Systems and methods for directly monitoring energy flux of a solar receiver in a solar energy-based power generation system include measuring infrared radiation emanating from the solar receiver. Such measurement can be achieved using one or more infrared thermography detectors, such as an IR camera. Resulting thermal data obtained by the imaging can be used to determine energy flux distribution on the receiver. A user or a system controller can use the determined flux distribution to adjust heliostat aiming to achieve a desired operation condition. For example, heliostats can be adjusted to achieve a uniform energy flux distribution across the external surface of the receiver and/or to maximize heat transfer to a fluid flowing through the receiver within system operating limits.Type: GrantFiled: July 9, 2009Date of Patent: January 13, 2015Assignee: Brightsource Industries (Israel) Ltd.Inventors: Yoel Gilon, Ophir Chernin, Gideon Goldwine, Gil Kroyzer, Rotem Hayut, Dan Franck, Israel Kroizer, Ziv Aumann

Publication number: 20140261390Abstract: A solar receiver includes a wavelength selective coating comprising a first diffusion barrier layer, a metallic IR reflective layer, a solar absorptive layer, an anti-reflective layer, and/or a hard coat protective layer. Selective absorber coatings, which are characterized by a high solar absorption coefficient and low thermal emission, can be used to convert captured solar radiation into usable heat. In embodiments, more efficient selective coatings are provided that combine relatively high solar absorbance (e.g., greater than about 0.96) with relatively low thermal emittance (e.g., less than about 0.07 at 700° C.), and that are thermally stable above 600° C., for example, in outdoor conditions. The use of such coatings in a solar field may allow for an increase in the operating efficiencies thereof at operating temperatures of about 600° C. or greater.Type: ApplicationFiled: March 11, 2014Publication date: September 18, 2014Inventors: Ophir CHERNIN, Christina HILDEBRANDT, Andreas GEORG, Thomas KROYER, Wolfgang GRAF

Patent number: 6669097Abstract: A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock.Type: GrantFiled: April 4, 2000Date of Patent: December 30, 2003Assignee: Symbol Technologies, Inc.Inventors: Paul Dvorkis, Edward Barkan, Howard Shepard, Joseph Giordano, Yuri Gofman, Robert Doran, John Barile, Henry Grosfeld, Avi Korenshtein, Kevin Cordes, Ophir Chernin, Mitch Maiman, Patrick Wallace
