I call it The Ghost Door. It is a device to open and close various types of hinged doors and latch them closed using undisclosed sensor systems. I have the drawings and design ready to begin prototyping, and by dedicating myself full-time to learning and implementing small scale tech like Arduino/Pi/Intel/etc materials, it’s about working to bring an idea to functional concept. It helps to have a programming background of sorts, and the skills to research the right guides to do small time electronics work like soldering and working through issues. I can totally build this thing in my garage if I had the time and money, at least to the point of working with some engineers to optimize it for mass production.

What’s great about the product from an investment and revenue standpoint is that it works in both “retro-fit” and “brand new” applications. It should be able to be mounted and used on interior doors for the mobility impaired or for convenience.

In conjunction with manufacturers, the design and technology can also be incorporated into industrial / commercial / medical door applications as a competitor to existing products. As of now, it’s not quite an ‘internet of things’ device — thinking of security here — but the potential to be such a device is built-in to the concept’s scope. The device has one primary goal: To open and close doors in a novel manner that will be a profitable product.
