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.

Silicone Cabling
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Standard and custom high flex silicone flat cables from Cicoil (Valencia, CA) are free of halogens, do not shed surface particulates, and are water and chemical resistant. The cables are suitable for incorporation into power conductors, shielded signal pairs, video and coax conductors, tubing for air or fluid transfer, and other design elements such as Cicoil’s patented Strip Mount™ fastening strip. The silicone encapsulation provides a solid, one-piece construction that creates a durable cable package with a lifetime of more than 10 million cycles, even under high-speed flexing or tight bending radius conditions. The cables are impervious to water, steam, UV light, and most chemicals, and are suitable for vacuum environments. Cables are available in continuous lengths, cut to order, or as assemblies, complete with connectors.

Compact Connectors
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Spectrum Advanced Specialty Products (Fairview, PA) has introduced the Mini-MIL circular connector, a small, lightweight connector that offers space and weight savings with performance equivalent to MIL-DTL-38999. It is available filtered and unfiltered with feed-through or Pi capacitance, and comes in a durable package designed for rugged applications that require high-performance EMI filtering. It is suitable for medical applications where size and/or weight restrictions do not allow for the use of standard-size MIL-DTL-38999 connectors. Custom connectors are available to meet high performance needs.

BGA Socket
Posted in Electronics & Computers, Electronics, Products, MDB on Friday, 01 July 2011
Ironwood Electronics (Burnsville, MN) offers a BGA socket for 1.118 mm pitch, 729 pin BGA IC’s. The SG-BGA-6345 socket is designed for 31 × 31 mm package size and operates at bandwidths up to 8 GHz with less than 1 dB of insertion loss. They are designed to dissipate up to several watts without extra heat sinking and can handle up to 100 watts with custom heat sink. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 8 GHz bandwidth on all connections. It is mounted on the target PCB with no soldering, and is constructed with shoulder screw and swivel lid which incorporates a quick insertion method so that ICs can be changed out quickly. The temperature range is -35 °C to 100 °C. The pin self inductance is 0.15 nH and mutual inductance is 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin.
