Crane Aerospace and Electronics released its new 1120 and 1130 switch matrices. These matrices have 144 inputs and 144 outputs and 20,736 cross points – the highest I/O arrangement for Crane. The 1130 has been configured for ECL signals and, according to Crane, provides a transfer rate of 300 MB/sec. The 1120 has been configured for RS-422 signals and provides a lower transfer rate of around 10 MB/sec.
Users can interface the matrices through a built-in keypad and screen navigation, or by connecting with a PC through an RS 232 serial port or TCP/IP connection. The system is user dependent, with options to modify data output and set conditions, though it has built-in test features for signal detection and to monitor power and internal temperature.
Both the 1120 and 1130 matrices come equipped with redundant and user-replaceable power supplies in order to prevent downtime. When one power supply fails, the second is initiated to sustain the functions of the matrix. An alarm is triggered upon power failure to alert the user. Power supplies are replaceable through the front for user convenience.

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
