Who would've thought?

This may more properly belong on my Bethune Catholic blog as it relates to to our small holding, but....

One of our tricks to prevent dogs from digging into our chicken pen is to lay wire or fencing on the ground around the pen.

Here's the set-up. We have a large inner chicken pen which surrounds a chicken yard and the chicken houses. It is "roofed" with either chicken wire or horse fencing. Then, about four feet from the pen we have an outer fence, four feet high.

We have a two-fold anti-digging deterrent system. On the forest side of the chicken pen, we have an old section of chainlink fence laid flat on the ground and semi-secured with moisture barrier wires. Thus dogs (or foxes or coyotes) would have to start digging some four feet away from the outer pen fence to gain access to the inner chicken pen. Between the outer fence and the inner pen we have lined the ground with chicken wire all around the inner pen. Thus, if a dog dug under the outer fence, it would get caught under the wire. If the dog jumps the outer fence, it still can't dig into the inner pen.

All that said, I was doing a little not so random research on the US Patent and Trademark patent data base and found the patent, imaged below.

In case you can't read the "Abstract" on the figure, it reads (my emphasis):

Animals can be prevented from digging in an area by positioning a plastic mesh barrier on the surface of the earth where it is desired to prevent the digging. The mesh can be anchored so that it will remain reliably positioned and will become nearly invisible as vegetation grows through the openings of the mesh.

Who would have thought a plastic mesh would be as effective as a wire one? (The inventor claims it is in the patent.)

In the news

A little off track, but I saw this story this morning and thought it was worth some general comments. I know little of the particulars and haven't reviewed the patent application myself.... From The Times (via Foxnews) :

Microsoft submitted a patent application in the U.S. for a "unique monitoring system" that could link workers to their computers.

Wireless sensors could read "heart rate, galvanic skin response, EMG, brain signals, respiration rate, body temperature, movement facial movements, facial expressions and blood pressure," the application states.

The system could also "automatically detect frustration or stress in the user" and "offer and provide assistance accordingly."

Physical changes to an employee would be matched to an individual psychological profile based on a worker's weight, age and health.

If the system picked up an increase in heart rate or facial expressions suggestive of stress or frustration, it would tell management that he needed

"This system involves intrusion into every single aspect of the lives of the employees," Hugh Tomlinson, an expert on data protection law at the London law firm Matrix Chambers, said. "It raises very serious privacy issues."

The U.S. Patent Office confirmed Tuesday that the application had been published last month, 18 months after being filed. Patent lawyers said that it could be granted within a year.

Are there ethical issues in obtaining patents? Surely there are. I turned down a job once when I found out that the company I applied to was into researching contraceptives and the like. I wasn't going to write patent applications for such things.

How about this patent application? Well, I am not sure the concept itself is unethical-it just has to be used with consent and no pressure and for a good purpose. (For example: Is the concern for the worker or for revenues?)

Yet we know that promises of no pressure don't last long. Many states have laws where you can't force someone to work on Sundays, or punish them if they refuse. But we all know of instances where people get poor schedules or are eventually let go because they want to keep the Sabbath holy.

And, this system may already be in use.

The patent application was filed in June 2006 and describes a system which must be workable to be patented. By this time, I am willing to bet that it has been tested on someone, and may even be implemented in some places.

Microsoft isn't doing this for their own employees necessarily. They may want to introduce it into an office near you!

Technology isn't necessarily bad, but you have to apply it and use it ethically. Unfortunately we are are a low point in ethics in this country. People think things are only wrong if you get caught-there is no real moral right or wrong. So we must be careful with technology.
