High Power LED Chip Array Packaging
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Electronics, Electronic Components, Power Supplies, Thermal Management, Power Management, Medical, Lighting, LEDs, Features, MDB on Thursday, 01 November 2012
The last few years have seen the development of larger, higher power, higher luminescence light-emitting diode (LED) chips. Prior to this, LEDs were typically 0.020" x 0.020", came in various colors and were used primarily as optical indicators. This new breed of LEDs come in various colors, including white and UV, are typically 0.040" x 0.040" and are designed to provide high intensity light for illumination applications. Individually packaged versions of these LEDs are being used in arrays and clusters to replace standard incandescent and compact fluorescent light bulbs and are much more efficient at converting electrical power into usable optical power.

Ultra-Sensitive Biosensor for Medical Diagnostics
Posted in Bio-Medical, Electronic Components, Sensors, Medical, Diagnostics, Briefs, MDB on Sunday, 01 July 2012

This device may enable miniaturization and new point-of-care applications in doctors' offices.

Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A. Alam, a Purdue Uni versity professor of electrical and computer engineering.

Panel-Mounted Latching Connectors
Posted in Electronic Components, Products, MDB on Sunday, 01 July 2012
Omnetics Connector Corporation (Minneapolis, MN) offers Latching Micro- D™ connectors with a new squeeze-latch system suitable for making quick cable connections to rack and panel equipment. In addition to being small and lightweight, the connectors, at .050" pitch, have passed extensive shock and vibration testing, including pull tests exceeding 100 pound pull force. The design eliminates the use of screwdrivers and hand tools. Medical devices, such as surgery tools, ultrasound monitors, and optical scopes require frequent connection and removal from instrument panels. These panel-mount connectors offer options for connecting inside the instrument, including P.C. board lead frames and direct wiring. Highly rugged and compact designs using aluminum alloy 6061 shells with nickel plating offer contact counts from 9 to 51 positions. Operating temperature ranges from -55 to 125 °C.

Crimp Terminal
Posted in Electronic Components, Rehabilitation & Physical Therapy, Patient Monitoring, Products, MDB on Sunday, 01 July 2012
Molex Incorporated (Lisle, IL) has introduced the Mini-Fit® Plus HMC (High Mating Cycle) crimp terminals, suitable for medical equipment manufacturers developing commercially available products such as patient monitors, diagnostic imaging devices, therapeutic machines, and patient handling equipment. They are rated up to 1,500 mating cycles and capable of up to 13.0A per circuit. The Mini-Fit HMC is available in wire-to-wire and wire-to-board configurations and offered in three wire gauge sizes, 16 AWG, 18 to 20 AWG, and 22 to 24 AWG. The terminals can be used with existing Mini-Fit receptacle and plug housings and with existing Mini-Fit and Mini-Fit Plus HCS headers.

Coaxial Nanocable Could Aid in Energy Storage
Posted in Batteries, Electronic Components, Energy Storage, Energy Efficiency, News on Friday, 08 June 2012
Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.
