Rugged Spring Pins
Posted in Electronics & Computers, Electronics, Products, MDB on Thursday, 01 September 2011
Mill-Max (Oyster Bay, NY) offers a series of rugged spring pins capable of carrying 9 amps continuous current at 10 °C temperature rise. The Mill-Max 0850, 0851, 0852, and 0853 spring pins are suitable for rugged applications and for use in circuits operating above signal level. The 085X series is characterized by a greater mass and surface area, which provides a lower resistance electrical path than miniature spring pins. The spring pins feature a gold plated stainless steel spring, .050" diameter solid plunger, and thick wall construction to withstand demanding applications. They are designed for through-hole mounting, and each pin has a large diameter post and flange providing for a perpendicular and secure P.C.B. attachment. The 085X series provides .045" mid-stroke and .090" maximum stroke, allowing for use in applications where stack up tolerances are great. Applications include board stacking, docking stations, cable assemblies, quick connects, and anywhere there is a blind mate solution. The series is rated at 1,000,000 cycles minimum.

Filter/Amplifier Card
Posted in Electronics & Computers, Electronics, Products, MDB on Thursday, 01 September 2011
Krohn-Hite (Brockton, MA) offers the Model FLX-ICP4, a four-channel filter/amplifier with a flexible signal conditioning card suitable for use in ICP® sensor and other sensor/transducer applications requiring a constant excitation current. A user-selectable 4mA or 8mA constant current is provided for excitation power to the input of the ICP® sensor, while the return AC signal is conditioned through a differential fixed filter/amplifier. The FLX-IPC4 can be populated with up to 4 independent channels, including a fixed low-pass Butterworth or Bessel filtering from 1hA to 200kHz and a fixed low noise gain up to 10,000. The filter provides a typical common-mode-rejection of >80dB and a signal-to-noise ratio of >100dB. Typical noise is

Non-Magnetic D-Sub I/O Connectors
Posted in Electronics & Computers, Electronics, Products, MDB on Thursday, 01 September 2011
CONEC (Garner, NC) has enhanced its I/O connectors for use in areas with high magnetic fields by replacing the usual steel shells and hardware with tin-plated brass and making the brackets of diecast zinc. The non-magnetic D-Sub I/O connector is suitable for medical imaging systems and other medical applications. The nonmagnetic D-subs are available in standard densities of 9 through 50 positions, in solder cup and PC tail versions. High-density D-subs in the product line include sizes from 15 to 78 positions, also in solder cup and pc tail versions. Combination D-subs are available in 21 standard arrangements. EMI filter connectors are also available with this nonmagnetic capability. Current ratings are from 5 to 40 amps, depending on the base connector chosen.

Wrist-Mounted Device for the Visually Impaired
Posted in News, Electronics & Computers, Electronics, Manufacturing & Prototyping, MDB on Tuesday, 23 August 2011
The Tacit, a haptic sonar glove that helps a visually impaired person navigate complex environments, has been released as a public prototype. The invention uses ultrasonic sensors to sense objects from about 1 inch to 10 feet away, and translates that information into pressure on the user's wrist.

Flexing the Power of Skin-Mounted Electronics
Posted in News, Electronics & Computers, Electronics, Sensors, Medical, Patient Monitoring, MDB on Friday, 12 August 2011
Engineers are taking important steps toward a future in which skin-mounted electronics could monitor individuals in a natural environment and even offer the potential for human-computer interfacing — all with the flexibility and comfort of a temporary tattoo.

Researchers at the University of Illinois and Northwestern University recently developed a type of patch with a circuit that bends, wrinkles, and stretches with the mechanical properties of skin. The patches are mounted on a thin sheet of water-soluble plastic, then laminated to the skin with water, like a temporary tattoo.

Waving ‘Jell-O’ to the Next Wave of Biocompatible Electronics
Posted in News, Electronics & Computers, Electronics, Materials, Coatings & Adhesives, MDB on Friday, 15 July 2011
North Carolina State University researchers have developed a memory device that is soft, functions well in wet environments, and features “the physical properties of Jell-O,” according to Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the research. The device’s pliable nature and biocompatibility could open up new possibilities for biocompatible electronic devices.
