Patent number: 11709333Abstract: A holographic sight comprises a unitary optical component carrier having a plurality of receptacles for receiving optical components. A collimating optic abuts a surface of a first receptacle. A mirror abuts a surface of a second receptacle. A collar is positioned in a third receptacle and a laser diode is positioned within the collar. A first portion of the collar is affixed relative to a first portion of the third receptacle and a second portion of the collar is free to expand and contract relative to the third receptacle. The laser diode is affixed to the collar proximate the second portion and is free to move relative to the third receptacle with expansion and contraction of the second portion.

Patent number: 10292402Abstract: Edible seeds are sanitized with a composition comprising water, a biocidal agent and a solvent. The composition is applied to the seeds and the seeds are later dried without first rinsing the seeds. The application rate may be 15% by weight of the seeds or less. The solvent may be a water-miscible alcohol such as ethanol or propylene glycol. When sanitizing mucilaginous seeds, the composition comprises one or more alcohols in an amount effective to inhibit the release of mucilage. The composition is initially applied as a mist to mucilaginous seeds. The biocidal agent may be an oxidizer such as peracetic acid. A treatment system includes an atomizing sprayer and a dryer, for example a fixed bed forced-air dryer.Type: GrantFiled: November 13, 2015Date of Patent: May 21, 2019Assignee: Agri-Neo Inc.Inventors: Johannes Mathieu, Nicholas Dillon, Fadi Dagher, Devin Thomas Michaud, Steven Kent Whitesides
