Researchers create multi-colour LEDs

17 October, 2005

A team of University of California scientists at Los Alamos National Laboratory have developed what it claims is the first inorganic, multi-colour light-emitting diodes based on colloidal quantum dots encapsulated in a gallium nitride semiconductor.

Let there be light...emitting diodes

Russell Dupuis talks about the development and future of this revolutionary technology in conversation with Jane Sanders

LED current driver

04 October, 2005 | Supplied by:

LEDs in arrays need constant current driving - for consistent driving current through each LED. Putting a resistor across each LED will not ensure the current through each LED in the array will be the same because every LED has its own voltage drop value.

Processor core

04 October, 2005 | Supplied by:

The phyCORE-ARM7/LPC229x supports high-performance, low power LCP2292 and LPC2294 ARM7TDMI-S devices from Philips that offer up to four on-chip CAN nodes.

Lightweight relays

04 October, 2005 | Supplied by:

Leach International has developed two small, lightweight relay series - KX and KUL - designed to carry high-current loads up to 300 A.

Circuit elements for opto frequencies

10 September, 2005

Researchers at the University of Pennsylvania propose to shrink circuits to save space and power and, more importantly, accommodate electronic applications at much higher frequencies than are possible with current models - applications that include nano-optics, optical information storage and molecular signalling.

Intelligent AC motor soft starter

01 September, 2005 | Supplied by:

Designed for single phase compressors of up to 6.5kWatts (6.5 shaft horsepower), i-Start's patented switching technology not only reduces start-up currents to less than 45Amps, it reduces electrical load and hence wear on the starter as well, offering the potential of longer life for both compressors and starters alike.

Broadband TWT amplifiers

01 September, 2005 | Supplied by:

RFI Industries has released the TMD range of broadband TWT amplifiers.

Underwater piezo speaker

01 September, 2005 | Supplied by:

Based on the in-house expertise in vibration characteristic of piezoceramic material and microacoustics, Sonitron has developed what it claims is the first flat piezoceramic speaker for underwater applications.

Single board computers

03 August, 2005 | Supplied by:

SBS Technologies has introduced three 6U CompactPCI single board computers.

RFID reader cards

03 August, 2005 | Supplied by:

Richardson Electronics has signed a strategic partnership with WJ Communications to represent the global sales channel for its multi-protocol MPR 5000 and MPR 6000 RFID reader cards, available in a standard PCMCIA Type II package.

Motor range

03 August, 2005 | Supplied by:

M Rutty & Co is proud to announce that they are the new Australian representative for Mavilor Motors.

ARM operating system

03 August, 2005 | Supplied by:

Keil Software has announced the advanced real-time operating system for ARM (ARTX-ARM), a flexible real-time operating system with TCP/IP networking and flash file system support for ARM-based controllers.

Light beams tied in knots

15 July, 2005

Researchers from the British universities of Southampton and Glasgow have succeeded in tying knots in light beams.

LTC3780 buck-boost controller

06 July, 2005 | Supplied by: Soanar Limited

Linear Technology has introduced the LTC3780, a buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage.
