Four years ago, they broke through the microwatt barrier and into the milliwatt
Under a Defense Advanced Research Projects Agency program, the company sought to produce 20 milliwatts
of continuous wavelength and power with an initial goal of attaining 40 percent wall plug efficiency.
Alaser pointer that can be bought over the internet, a socalled Class IIIa device, has a power output of less than five milliwatts
. That''s pretty puny, less that one thousandth the power of a domestic light bulb, and fi ures from the United States Foods and Drugs Administration have suggested that you might have to stare down the beam for as long as ten seconds to suffer any eye damage - the exact figure depends on the colour of the laser light.
The laser with the high output of 450 milliwatts
will allow a DVD disc to record 8 hours of video, two times more than with a conventional 250-milliwatt laser, Sanyo said.
The types that can reach aeroplanes are much more powerful and dangerous and are for sale online at strengths of up to 500 milliwatts
The output of the micro-generator can easily cover the power needs of intermittent radio sensor systems such as Wireless HART, SP-100 and Wi-Fi in industrial applications, but its output impedance is too high to supply the 10s to 100s of milliwatts
required by sensor nodes during data collection and transmission.
That equals 36 microwatts--microwatts, not milliwatts
. A mainline pressure transducer can draw 5 milliamps at 5 Vdc, equaling 25 milliwatts
of required power.
Carrying this analysis on to the sphere of TVs, phone chargers, PCs and so on, each consuming power measured in milliwatts
, and the result is a thin line at the base of the bar chart I am constructing.
The transmitter consumes 8.8 milliwatts
, or about one-third as much power as other implantable transmitters, while transmitting 10 times more information.
The program goal is to develop a one cubic centimeter AlphaVoltaic (AV) battery that can deliver 35 milliwatts
continuously for many months to many years.
About 70 to 100 milliwatts
is generated when a person passes through a ticket gate.
That's because the processor runs at 300 milliwatts
(a 400-mW version is coming, and a 600-mW version is on the horizon), and draws very little amperage in comparison.
