AVX Corporation has developed a wire-to-wire (WTW) connector system for junction applications, which offers a simple and reusable method for connecting discrete wires and leaded components in electrical and electronics applications. This extension of the 9286 Series WTW connectors does not connect wires in the traditional 1:1 configuration; instead it connects numerous wires … [Read more...]
Determining Space for Capacitors and Resistors with Unidirectional Terminations
IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the … [Read more...]
Impact of the Upcoming Medical RF Immunity Revision
As indicated last time, there are two key parties with a vested interest in the outcome of the upcoming Medical RF immunity revision:The test house manager who has to justify an upgrade to his test system to the people holding the purse strings.His customer, the company wishing to sell medical equipment compliant with the revised standard.I shall add a third … [Read more...]
Researchers Create Wi-Fi-Blocking Wallpaper
Researchers at the Centre Technique du Papier in France have developed a wallpaper capable of blocking Wi-Fi and cellphone signals. Known as "metapaper," the wallpaper utilizes a conductive ink to filter out specific frequencies, preventing signals from traveling in or out of an enclosed area. The researchers theorize that the wallpaper may become most useful in places where … [Read more...]
Physicists Find Silicon Lenses Focus Gamma-Rays
Researchers at the Institut Laue-Langevin (ILL) in Grenoble, France have demonstrated that silicon lenses can be used to focus gamma-rays just like visible light, undermining the decades-old belief that gamma radiation cannot be manipulated optically. Professor Dieter Habs of Ludwig-Maximilians University Munich and the Max Planck Institute for Quantum Optics in Garching hopes … [Read more...]
