  • Drive High Intensity White LEDs Efficiently Using the PIC16C781
    High intensity white LEDs are rapidly gaining popularity because of their high light output for relatively low input current. Applications include small flashlights, backlighting, night visibility strobes for pedestrians and bikers, just to mention a few. This Technical Brief dis-cusses how
  • Buck Configuration High-Power LED Driver
    The circuit and firmware described in this application note demonstrates a minimal parts count driver/controller for a high-power (1W or greater) LED. The circuit is based on a buck topology switching power supply using the on-chip comparator peripheral within the PIC12F675 PIC (R) microcontroller
  • Sensor Lets Machines See Color Intensity
    EMX Industries Inc. introduced the ColorMax-1000, the first color sensor that outputs color intensity. EMX Industries Inc., introduced the ColorMax-1000, the first color sensor that outputs color intensity. The ColorMax-1000 color sensor has a high-intensity white LED that projects modulated light
  • Accuracy optimization of True Color Sensor solutions for LED color control of multiple LED light sources
    temperature control of for example 6500K, 4500K and 2700K and additionally compensate the negative side effects of LEDs. It is a known fact that LEDs are effected by temperature drift effects by shifting in wavelength and intensity. Additionally the latter is intensified by the aging factor. In many
  • MICRO: Spotlight
    with contact-angle measurement to evaluate wafer surface conditions. Included is a high-resolution camera and magnifying lens with high-intensity LED lighting for precise image capture. (S.F., North Hall, Booth 5160) designs and manufactures x-ray-based tools for the semiconductor manufacturing industry
  • Flexible circuit helps shed light on optical inspection line
    The L2 Illuminator employed in an optical inspection system provides uniform, high-intensity light. The Illuminator is used with equipment that inspects IC carriers and lead frames. Careful placement of LEDS on lamp side panels provides uniform, highintensity lighting from all internal surfaces
  • Medical Device Link .
    A medical device manufacturer in Ronkonkoma, NY, has developed a catheter-based system using high-intensity focused ultrasound (HIFU) to treat atrial fibrillation (AF). ProRhythm 's ( ) AF ablation catheter focuses therapeutic ultrasound energy by use of a proprietary dual-balloon design
  • Medical Device Link .
    machining involves removing material using a pulsed, high-intensity laser beam of often extremely short pulse duration. The beam is generated by any number of different laser technologies, but this article discusses pulsed laser systems in the picosecond range, and compares these with other pulsed lasers
