This is marvelous technology. Caltech and UC Irvine have been developing it for years. Not degenerate, though, so higher performance not possible.
A new generation of symmetrical devices are coming out soon with drift rates as low as 0.02 deg/hr and ARW of 0.003 deg/ rt hr and thermally compensated by a firm in California.
For crash prevention the outputs of MEMS sensors need to be foolproof, since only milliseconds can make the difference between life and death during a major accident. ADI's quad-differential gyros use redundancy and differential noise cancellation to nix any sensor mistakes before they happen.
A Book For All Reasons Bernard Cole3 comments Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
