RF/EMI Shields
Posted in Electronics & Computers, Electronics, Products, MDB on Monday, 01 March 2010
Photofabrication Engineering (Milford, MA) has introduced a line of EMI/RF shields with snap-on/snap-off covers, allowing access to components within the shields. The shields are designed to protect components from radio frequency/electromagnetic interference and environmental hazards, and to provide electrical grounding in medical and biomedical equipment. Standard forming tools are available in any size and shape to create covers that attach onto a fence, yet can be removed and replaced easily. The photochemically etched fences have grooves etched approximately 50% of the material thickness, so custom spring finger designs snap into them firmly. Shielding options for circuit board applications include one-piece or two-piece construction; standard base materials such as brass, tin, tin-lead, nickel, copper, and cold-rolled steel, all of which can be provided with solderable plating; and nickel-silver base material, which does not require additional finishing because it is already solderable.
Modular Electronic Air Sterilization Technology

This germicidal irradiation system eliminates airborne bacteria, molds, and viruses in one pass.

Ultraviolet germicidal irradiation (UVGI) technologies are being used as infection control devices, primarily in healthcare facilities. No standard exists, but the dose of UV and the airflow are critical to ensuring all contaminated air is treated. The UVGI process is mainly influenced by the microorganism population, the irradiation intensity, and the intimate exposure time to the lamps. This new technology enables the system to increase the intensity field or to improve the inactivation process, without adding more energy or increasing the output efficiency of the lamps.

ITT Interconnect Solutions (Santa Ana, CA) has an nounced the QLC ZIF (zero insertion force) connectors for portable medical equipment that feature a 260-position pin count. Constructed with a lightweight aluminum shell, the connectors feature a quick-disconnect latch for easy mating and unmating, as well as EMI and RF shielding. The connectors can withstand up to 20,000 mating cycles.
Remote Diagnostic Technology for Hearing Assessment
Posted in Bio-Medical, Electronics & Computers, Electronics, Medical, Patient Monitoring, Briefs, MDB on Tuesday, 01 September 2009

Clinicians can remotely assess, diagnose, and remedy hearing loss.

Individuals with hearing loss need to have ready access to hearing screenings, assessments, treatment, and consultation. This diagnostic technology facilitates early detection and intervention of hearing loss. It allows for improved monitoring and expands service scope, reach, and access. By reducing or eliminating travel times, it is also a more efficient utilization of time for audiologists and professional staff. The tele-hearing device and protocol provides clinicians the tools and the ability to remotely assess, diagnose, and remedy hearing loss. This is accomplished either directly or indirectly by facilitating assistance to other less experienced clinicians remotely.
Nano-Pervaporation Membrane With Heat Exchanger Generates Medical-Grade Water
Posted in Bio-Medical, Electronics & Computers, Electronics, Medical, Briefs, MDB on Tuesday, 01 September 2009

A small system produces high-quality water using a heat exchanger that meets requirements for evaporation of substances such as pharmaceuticals and vitamins.

A nanoporous membrane is used for the pervaporation process in which potable water is maintained, at atmospheric pressure, on the feed side of the membrane. The water enters the non- pervaporation (NPV) membrane device where it is separated into two streams — retentate water and permeated water. The permeated pure water is removed by applying low vapor pressure on the permeate side to create water vapor before condensation. This permeated water vapor is subsequently condensed by coming in contact with the cool surface of a heat exchanger with heat being recovered through transfer to the feed water stream.
Wireless Brain Implant Using a Telemetric Electrode Array System
Posted in Bio-Medical, Electronics & Computers, Electronics, Implants & Prosthetics, Medical, Briefs, TSP, MDB on Tuesday, 01 September 2009

A 3D intra-cortical electrode array is embedded for signal acquisition, processing, and wireless communication.

The ability to monitor the activities of ensembles of single neurons is critically important in understanding the principles of information processing in the brain that underlie perception, cognition, and action. Multiple microelectrode recording using appropriate neuronal implants provides this ability. The Telemetric Electrode Array System (TEAS) project aims at developing and embedding a three-dimensional intra-cortical electrode array with all electronics required for signal acquisition, processing, and wireless communication entirely into the head.

For companies that do not need NASA-developed technology or advanced test facilities but still want to leverage some of the brain power of NASA’s engineering teams to solve a design problem in their product, NASA funds the Space Alliance Technology Outreach Program (SATOP). Administered by Bay Area Houston Economic Partnership, SATOP is a cooperative program among Florida, New Mexico, New York, and Texas that brings together more than 55 space companies, universities, colleges, and NASA centers to make NASA expertise available to small businesses.
