About Scott Grimshaw
I currently run a company called Tangidyne, based in upstate New York, which researches and manufactures a variety of solid state electronic sensors.
I worked in the semiconductor and optics industries for 10 years on integrated circuits, optical devices and solid state electronic sensors and in mid 1987 I decided to strike off on my own.
I began by creating my own technology company in 1990 and named it Cold Springs R&D. Cold Springs manufactured a quartz crystal sensor used to measure thin film coatings made by a technique called vacuum deposition. These quartz sensors are a disposable commodity that are produced in the millions each year and used by manufacturers of lenses, lcd monitors and a variety of electronic and optical products.
The market for these sensors is relatively small, and my company eventually managed to capture approximately 50% of the US market in the 13 years I ran the firm. That was about that time that I decided to move on and start inventing new products that have a much larger sales potential.
To accomplish that, I started Tangidyne. Here I have spent the past 4 years investigating new product concepts and building a variety of new inventions.
Tangidyne has been awarded 4 US patents, 1 UK Patent, and has 3 more applied for in fields as diverse as cargo container security, candles, and air quality sensing . I am now building products based on several of these patents. I am also licensing or selling the patents for products that are not practical to market directly through Tangidyne.
Active Projects
I'm experimenting with a mold detector for indoor air quality monitoring, based on my patented transparent quartz crystal sensor technology. It's designed to detect the early stages of black mold (Stachybotrys chartarum), a fungus that has been linked to respiratory illness and possibly death in infants (the Cleveland Outbreak).
I have built a door hinge, dubbed the PiezoHinge™, that doubles as a self powered RF transmitter . This hinge, which can be used in applications in homes, cargo containers, tractor trailers and the like, sends a uniquely coded wireless signal (WiFi) whenever the hinge is moved. It will never need batteries.
This device has been incorporated into a cargo container security system developed by Joe Ryan and Bob Salisbury of Virginia Beach, Virgina. A related application is for use in monitoring cargo on trucks, or building security systems.
I am currently working on a novel real-time method of identifying chemical substances present in air. It's based on the same transparent crystal sensor that is being used in the mold detector, and acts as a miniature solid state spectrophotometer. Ultimately, I believe this could be a new class of cheap, low power (9 Volt battery) and portable chem/bio detector.
