Seeing the birth of the universe in an atom of hydrogen

September 6, 2012 10:24 am | by EurekAlert! | News | Comments

Windows to the past, stars can unveil the history of our universe, currently estimated to be 14 billion years old. The farther away the star, the older it is — and the oldest stars are the most difficult to detect. Current telescopes can only see galaxies about 700 million years old, and only when the galaxy is unusually large or as the result of a big event like a stellar explosion.

Pressure sensor designed for mobile phones, portable devices

September 5, 2012 2:13 pm | Stmicroelectronics | Product Releases | Comments

STMicroelectronics has introduced a new pressure sensor that allows mobile phones and other portable devices to calculate their vertical elevation relative to sea-level with very high accuracy. This means that the mobile device will know not only on which floor of a building it is located, but almost on which step of the staircase.

Power supplies designed for compact spaces

The Norton Report: Removal of conformal coating with small sandblasters

September 4, 2012 9:45 am | by Jim Norton, President, Custom Products & Services, Inc. | Blogs | Comments

The development of conformal coating technology was driven to a large degree by the military and aerospace industries. While conformal coatings are mostly used on populated, printed wiring boards (PWBs), they are also used to protect components such as transistors, diodes, rectifiers, resistors, integrated circuits (ICs) and hybrid circuits including multi-chip modules (MCMs) and chip on board (COB).
