The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
Brian Hart Ltd., also known as Hart and Hart Racing Engines, was a motor racing engine manufacturer that participated in 157 Formula One Grands Prix, powering a total of 368 entries.

Hart's first inversor, also known as Hart's W-frame, is based on an antiparallelogram.The addition of fixed points and a driving arm make it a 6-bar linkage. It can be used to convert rotary motion to a perfect straight line by fixing a point on one short link and driving a point on another link in a circular arc.
Chain saw sales totaled $19.1 million in 1976, resulting in losses for the company and reflecting a flattening of future market potential. OMC discontinued them the following year.

During Hart's time at the University of Illinois, the computer center gave Hart a user's account on its computer system; Hart's brother's best friend was the mainframe operator and gave an account with a virtually unlimited amount of computer time; its value at that time has since been variously estimated at $100,000 or $100,000,000.
