The Schaffner Group has expanded its product range with new EMC/EMI filter modules. The FN9280 series is equipped with single-stage EMC/EMI filters while the FN9290 series has a double-stage EMC/EMI filter with an attenuation of up to 80dB. The FN9290 series is suited for applications with higher interference levels, and the B versions of both series are suited for use in … [Read more...]
Device Injects Medicine without Using Needles
MIT researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The jet-injection system delivers a range of doses to variable depths in a highly controlled manner. According to MIT, the design is built around a mechanism called a Lorentz-force actuator — "a small, powerful magnet surrounded … [Read more...]
More Choices in Shielded Medical Connector Line
Hypertronics Corporation has expanded its successful Shielded HyperGrip® connector line. In addition to the 19-position HG3, the product series is now also available in a 12-position HG2 and a 33-position HG4 providing customers with an expanded range of choices in high-reliability shielded medical connectors. The Hypertronics HG Shielded line offers customers all of the … [Read more...]
Part II: The Impact of the Upcoming Medical RF Immunity Revision
The test-house manager’s perspective continued: At well over a quarter of a million dollars just to replace the existing 26-1000MHz amplifier and the same again to cover 1-6GHz at 200W (will take two amplifiers), the test manager will need to justify half a million dollars for the amplifiers alone. And the total will likely rise to around $600,000 or more with other equipment … [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...]
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...]
Half Watt RF Driver Amplifier
Analog Devices, Inc. has introduced the ADL5324 half-Watt RF driver amplifier. The ADL5324 offers superior power efficiency and temperature tolerance. The ADL5324 operates over a wide temperature range (-40° C to +105° C), and can be biased to operate on less power. In addition, the ADL5324 features dynamically adjustable bias which allows RF designers to set the driver’s power … [Read more...]
Expanded Inlet Filter Series Boasts Added Attenuation
The FN9233 inlet filter series from Schaffner EMC now includes the new FN9233E that features an earth line choke with approximately 6 dB more attenuation compared earlier devices. With a high symmetrical and asymmetrical performance, the FN9233E was developed for devices and switching power supply units that require a high level of interference suppression such as in … [Read more...]
Petite Particle Accelerator Proton Gun Kills Tumors
Scientists at the Compact Particle Acceleration Corporation are developing a 13-foot-long particle accelerator that costs about $30 million. Most accelerators use large magnets to generate the electromagnetic field that pushes charged particles. The magnets require 10-foot-thick concrete shielding and bulky hardware. CPAC's prototype creates the electromagnetic field with … [Read more...]
Novel Features of Short Pulse Electromagnetics
IEEE EMC Society Washington DC/Northern Virginia Chapter Meeting 6:30 p.m. - 8:30 p.m., May 28, 2012 Rhein Tech Laboratories, 360 Herndon Pkwy, #1400, Herndon, VA 20170-4865 Short pulses are inherently ultra-wideband (UWB) and have been the subject of interest for various applications such as wireless communications, high speed data transfer, fast switches, high speed … [Read more...]
