Illumination technology, now including ultraviolet disinfection systems
A product development company with a focus on illumination systems. The company takes concepts and then develops high quality prototypes to demonstrate risk-reduced solutions for license to third parties. Some recent examples are shown above.
High efficacy systems from the inventor of the light guide disinfection system (US7534356). Ultraviolet (UV) light cannot reach surfaces that are shaded from the UV source (in cracks/crevices that lead to hospital acquired infections (HAIs), textured surfaces in foods/plants that enable fungal/mildew growth). The current remedy is chemical disinfectants/fungicides. The innovation uses a ‘dry fog’ of pure water directed near the surfaces to be disinfected, causing the UV to forward-scatter, illuminating the surfaces from many new angles/locations, reaching the shadows. Another innovation is the introduction of 'Dosimetric Avatars' (TM), which are dosimeters constructed to record surface irradiation that correlates with how a real object would react (e.g., a strawberry's surface being disinfected by UV-C), accounting for microscopic and/or macroscopic surface features that cause shadowing.

Augmented Reality Pusher Tray Systems
Use the front lens in a pusher tray as a light guide, upon which monochrome or full color decals are applied that illuminate. There are several advantages to this. First, manufacturers might well consider paying more for their products to be illuminated. Second, the light guide and label are both clear, and the illuminated graphics portion on the lens decal can be aligned with the product label, creating an augmented reality point of purchase marketing display. Third, sell labels to existing customers who've purchased the pusher trays, and since these labels change quite frequently (e.g. sales & price changes), it becomes an ongoing revenue stream.
US Patent Appl. No. 62/909,943
We've all seen restaurant menu boards that seem to light up when fluorescent-colored markers are used. The surface that is written upon is an exposed surface of a light guide. Another common use can be found in 'glow board' type toys. Some products have integral acrylic or glass sheet material that can be used as a light guide, such as those used in 'product pushers' and other merchandising displays found in supermarkets (patent pending).
Generally, a sheet of glass or acrylic that is illuminated on at least one edge by one or more LEDs. This is called edge lighting. Alternatively, the light can enter the surface of the sheet using a Window Puck (TM). In either case, once the light enters the sheet, it remains trapped between the top and bottom surfaces of the sheet until it exits out another edge, or is caused to exit a surface; e.g. by writing on the surface with a fluorescent marker, engraving the surface, or silk screening the surface ... or by applying this new DECAL to the surface! Light guides can be covered on their rear surface with a dark card to enhance contrast, an image-bearing card to add some additional daylight-only imagery, or can be used without the card or with perforated decals to add transparency.
They are numerous: small plug-in nightlights, mid-size desk lamps, hand held tablets (e.g. glow boards), and large easel- and wall-mounted versions . The wall mounted versions can be suspended from a ceiling, catilevered from a vertical wall, or placed on a hook like a picture. Note that existing products are either blank (requiring the consumer to provide their own artwork using fluorescent markers) or permanent (engraved or silk-screened images requiring the purchase of a new product for new images like that shown in the links for night lights and desk lamps). With these new technology decals, simply peel-off the old one, and apply a new one to the smooth exposed surface of the light guide (like those found on glow boards and LED writing boards, or have the night light and desk lamp manufacturers make blank versions), and it looks just as professional as engraved or silk screened! In fact, they make great neon signage at a fraction of the cost!
