Researchers at the University of Michigan have developed a solar-powered computer so small that it can be inserted into the human eye to help monitor glaucoma patients. Professor Dennis Sylvester explained:
In a package that's just over 1 cubic millimeter, the system fits an ultra low-power microprocessor, a pressure sensor, memory, a thin-film battery, a solar cell and a wireless radio with an antenna that can transmit data to an external reader device that would be held near the eye.
"This is the first true millimeter-scale complete computing system," Sylvester said.
"Our work is unique in the sense that we're thinking about complete systems in which all the components are low-power and fit on the chip. We can collect data, store it and transmit it. The applications for systems of this size are endless."
The processor in the eye pressure monitor is the third generation of the researchers' Phoenix chip, which uses a unique power gating architecture and an extreme sleep mode to achieve ultra-low power consumption. The newest system wakes every 15 minutes to take measurements and consumes an average of 5.3 nanowatts. To keep the battery charged, it requires exposure to 10 hours of indoor light each day or 1.5 hours of sunlight. It can store up to a week's worth of information.

Ted- I wouldn't call heart problems and diabetes laziness...
After years of fighting with the USPS about requesting non-delivery of the "pizza papers", I discovered a database of their regulations. I used the USPS own rules and regulations against them to stop getting the "pizza papers" in my box. They didn't take it well though.
The employees did not even know of this rule. I am betting that he did not know of it either. If he had, he probably would have told the people on his route about it.
More power to ya buddy
Plus, I bet if you supporters were the business owners who paid money to create these ads, you would be upset.
I think it was because he was lazy and not for the good of it all, because as Ali stated he could have put these ads in a recycling bin.
Frau, if you figured a way to keep the stuff that annoys you out of your mailbox with the legalese of the USPS, that is fabulous! Share with others, please! My own personal pet peeve is people other than my carrier slipping stuff into my mailbox. I find that many religious organizations are prone to doing that, and I've complained formally about it. People put strange things in the mail. Every spring brings baby chickens, ducks, and bees. Once a full grown peacock went through our local PO. How would you like to deliver that?
Doing something "wrong" is sometimes necessary to get a point across, and if he were my mailman, I would have definitely stood up for him.
I still call laziness. That's not pointing out the rules like a five-year-old. That's just stating the obvious.
yeah like a Zombie is alive.
