  • Patent number: 12072294
    Abstract: A variety of techniques for authentication of jewelry and gemstones is provided. With some examples, blockchain may be used to store a reference signature for the jewelry/gemstone, and a digital asset such as a non-fungible token can link this reference signature with the physical jewelry/gemstone. During an authentication process, the reference signature stored on the blockchain can be accessed and compared with a test signature derived from an item that is purported to be the original jewelry/gemstone to determine whether they match to support a declaration that the purported jewelry/gemstone is authentic.

  • Patent number: 11808628
    Abstract: A sunlight exposure indicator device is disclosed that can determine the amount of time (e.g., hours) of PAR sunlight that occurs in a specific area for the optimal growth of a plant, as corresponds to the plant industry common designations of Full Shade, Partial Shade, Partial Sun and Full Sun. These designations can be used to determine plant selection for all types of plants including grasses, shrubs, flowers, vegetables and herbs, and trees. This device utilizes irreversible, slow-reacting, photochromic pigments applied to a substrate. Using multiple instances of this device will allow someone to easily test and accurately determine the amount of PAR sunlight (hours) received during a one-day sunlight cycle in multiple spots simultaneously. The sunlight exposure indicator device is a one-time-use, non-electronic, disposable device.

  • Publication number: 20150116444
    Abstract: An imaging blanket for a variable data lithography printing system is disclosed that comprises a polymer body having incorporated therein carbon black and measured amount of surface-treated fumed silica. The carbon black serves to improve the thermal absorption efficiency for thermal patterning of a dampening fluid layer formed over the imaging blanket in use. The surface-treated fumed silica assists with desirable dispersion of the carbon black in the polymer body. The surface-treated fumed silica further assists with the formation of a surface micro-texture as part of the process of molding the imaging blanket. A method for manufacturing such an imaging blanket is also disclosed.

  • Patent number: 9001403
    Abstract: Methods and apparatus include improving print quality of a bi-directionally scanning electrophotographic (EP) device, such as a laser printer or copy machine, according to ambient pressure in which operated. A moving galvanometer or oscillator reflects a laser beam to create scan lines of a latent image in opposite directions. A damping of the motion occurs per air density implicated by temperature and pressure, where the pressure changes occurring especially from altitude changes. During use, a drive signal, such as a pulse train, moves the galvanometer or oscillator at or near its resonant frequency. Based on a parameter of the drive signal, such as pulse width, the ambient pressure can be made known. In general, a high-pressure environment requires a relatively longer pulse width to resonate the galvanometer or oscillator in comparison to a shorter pulse width for a low-pressure environment. Corrections to print quality stem from the determined ambient pressure.
