The LED can
be used wherever there are large fluctuations in temperature and a large amount
of light is needed from a small area. The thermal coefficient of expansion
of the molding material precisely matches the coefficient of expansion of the boards,
and there is an ESD protective diode concealed in the molding. The high output
efficiency in the black package does not require additional reflectors. The
materials have been chosen so that even large fluctuations in temperature do
not have an adverse effect on reliability or on the life of the LED (approx.
50,000 hours). The Oslon LED
has a low thermal resistance of 6.5 K/W.
The Oslon Black Series has a lens with
a 90 degree beam angle and produces a typical brightness of 115 lm at an operating
current of 350 mA and a color temperature of 6500 K. By increasing the operating
current to 1 A, it is able to achieve a brightness of 250 lm. The LED uses a 1 mm²
chip and is available in all colors, including warm white. The Oslon Black Series solder pad is
compatible with the other LEDs in the Oslon product family.
The LED is useful for signal lights, interior
lighting for refrigerators and lighting for train, planes, automobiles, and
industrial designs.
Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed.
New disc magnet motors fit into the design trend of stepping up to closed loop performance while maintaining the cost advantage of stepper motor technology.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
