This blog article talks about a situation that comes up frequently in all of our daily lives — removing the front cover of a circuit breaker panel and working on the panel. The main point of today’s article is that in the circuit panel shown at right, we recently added the two yellow caps shown at A. This makes the circuit breaker panel less dangerous.

I was astonished to hear from D-Link that it has shut down its cloud that makes its smart plugs work. Pictured at right is one of the three DSP-W110 smart plugs that I purchased from D-Link in 2016. I still own the plugs and one of the plugs still has a device plugged into it — a table lamp.
But as of today, I cannot turn the lamp on or off using the app on my smart phone. As of today, the D-Link smart plugs don’t do anything any more. Continue reading “D-Link IOT cloud evaporates”
Many readers know that during World War II, military aircraft used red internal lighting. Pilots used red flashlights to view maps while in flight. The reason for using red is that if ordinary full-spectrum (white) light had been used, this would spoil the “night vision” (vision using rods instead of cones). Red light does not harm night vision as much as white light. This blog article talks about using night lights around the house that are red instead of white. Continue reading “Red night lights”
I enjoyed immensely my first viewing of Glass Onion. I then enjoyed immensely my second viewing of Glass Onion. In this blog article I will reveal how you can get an identical copy of the digital voice recorder (seen at right) that appears on the screen in this movie at 42:14. Continue reading “Heavens, the dog ate the caviar again”
(Update: The letter did get sent, and the USPTO received the letter (blog article).)
This blog article provides a document The Fool’s Errand That Is DOCX, dated December 27, 2022. This blog article invites you to sign a letter urging USPTO people to read the document. Continue reading “The Fool’s Errand That Is DOCX”
(Correction — I am told that both AIPLA and IPO also contacted the USPTO privately in recent weeks about this problem.)
It looks like maybe the USPTO blinked on the non-DOCX surcharge problem, at least a little. What forced the USPTO to blink was a letter from 117 patent practitioners pushing back on a December 20, 2022 Federal Register notice. The notice maintained and doubled down on January 1, 2023 as a date that all US patent filers would face a harsh choice — incur substantial risks of losses of patent rights due to the DOCX program, or pay $400 to be able to file a patent application in a way that eliminated those substantial risks. The only visible pushbacks on this December 20, 2022 FR notice were:
- the above-mentioned letter signed by 117 practitioners, and
- ceaseless personal efforts by Bradley Forrest, a partner at the Schwegman firm.
In this blog article I briefly describe the state of play on the DOCX program as it now appears.

If you are like most folks these days, you are getting ready to install an EV charger at your home. You agonize about whether to get this brand of EV charger or that brand of EV charger. And then just as you think you figured everything out about which EV charger to purchase, you smack into a wall. The charger is available with two kinds of plug, a so-called “6-50” plug or a so-called “14-50” plug. Which variant of the EV charger should you choose? Which plug is the right one to pick?
It turns out that this is a trick question. But if you click here, you can read a blog article by someone whose writing style you might recognize, who answers this question for you.
I recently received this handheld distance measurement device. Like a laser pointer, it shoots out a narrow beam of red light, making a small red dot on a surface that might be 100 feet away. It then uses a built-in telescope to view the red dot of light, and works out the distance to that surface. The device arrived today, and I compared its measurement with that of a long fiberglass measuring tape. The two approaches yielded answers that differed by only a tenth of a percent. How does it work exactly?
Star Trek fans might be able to guess where I am going with this. There were episodes of Star Trek where an enemy had somehow found a way to bypass the Enterprise’s shields, at which point the captain on the bridge of the Enterprise would shout out “modulate the shield harmonics!” In the world of Star Trek, this modulation apparently restored the protection of the shields. And indeed this kind of laser distance measurement uses a modulation of a signal to accomplish its remarkable result. Continue reading “Modulate the shield harmonics!”
