When undertaking an activity causing sweating, a person can suffer from the effects of sweat dripping into his eyes. Many devices have been developed to address this problem, such as absorbent sweatbands. Such devices fail to prevent sweat from reaching the eyes once they become saturated, and must be dried or wrung out in order to restore their effectiveness...
Described herein are sweat-diverting devices which may be affixed to a wearer by an adhesive, such as a pressure-sensitive adhesive...
A sweat-diverting device may be reusable, with an adhesive reapplied for each wearing, or may be single use and disposable, with the adhesive integrated with the device during manufacturing.
The object of my invention is to provide a comparatively simple and practical wrinkle mask constructed of suitable pliable material preferably of rubber, which is adapted to envelop or cover the face or portion thereof to be treated and further for providing suitable means forming a part of the same for embracing the hair or head portion of the user, whereby the wrinkles or other deformities of the face may be easily and readily removed as will appear...
My invention dispenses with the usual work in massaging, employed for removing the wrinkles or blemishes from the face, and can be used at any time more particularly, however, at nights while the patient is sleeping.
Bohland managed to open a few auto wash bowls. The problem, however, was that his technique only really cleaned the underside of the cars. This was useful back in the days when many roads were still unpaved and their undersides constantly got filthy. But as road conditions improved, the auto wash bowl became less useful. By the 1930s, the last one had closed.
Patent #10,455,817 was granted in Oct 2019 for "animal olfactory detection of disease as control for health metrics collected by medical toilet."
In plainer language, it's a toilet that has a small door built into the side of it (the "scent dispenser"), allowing a dog to smell your poop (or other bodily fluids) in order to detect the presence of disease. From the patent:
The user deposits bodily waste into the toilet through actions which include urinating or defecting into the toilet, vomiting into the toilet, coughing up sputum into the toilet, and depositing mucus into the toilet...
An animal may be trained to sniff the scent dispenser in response to a command or signal. The user may give the animal the command or signal when the user desires the animal to assess the presence of disease in the user.
Oliver Halsted was granted a patent for an "exercising machine" in 1844. It was later marketed as the Health Jolting Chair. AKA the "wake-up chair." By pulling the levers on the side, it would bounce up and down. It was said to be a panacea for "dyspepsia, liver complaint, low spirits, general debility, constipation, 'so-called malaria,' jaundice, melancholia, and anemia."
July 25, 1967: During its broadcast of the TV series Combat!, ABC aired a commercial for a soft-drink called Squirt. The commercial appeared in color. What made this unusual is that it appeared in color even on black-and-white TV sets.
The commercial used a technology developed by the Color-Tel Corp., and patented by James Butterfield, that used pulses of light to trick the brain into thinking that it was seeing color. Butterfield described this as "subjective color".
The company had informed the media before the broadcast, but most people didn't know it was going to happen, and so they thought they were going nuts when they suddenly saw flashes of color on their black-and-white sets.

The technology had some limitations. It could only be used for still images. Also, the colors were muted and flickered a lot. But the really big problem was that the technology emerged just as color TVs were becoming popular. So it was a clever gimmick that no longer had much practical purpose.
I don't see what advantage an aroma disc would have over an incense candle (except, perhaps, for the lack of an open flame). Which, I assume, is why these are no longer around and incense candles are all over the place.
But Spector was successful enough to have his product featured on The Tonight Show with Johnny Carson:
AKA Cerebrex. Invented by Dr. Yoshiro NaKaMats. It was essentially a lounger chair that was supposed to improve brain function in only 30 minutes. Details from the Arizona Republic (Sep 12, 1986):
NaKaMats unveiled the chair this summer  and plans to mass-produce and lease the recliners for about 14,900 yen, or $93 a month.
Meanwhile, customers can use it only in his sun-flooded "oyasumidokoro," or sleeping place, a nearly empty room a few floors below his laboratory, where white-coated assistants bustle around prototypes of industrial robots in various stages of development.
The inventor explains how the chair works, sort of.
"It activates your alpha brain waves by emitting ultra-high frequency electronic pulses, which in turn increase the flow of blood to the head, through the chair's pillow and foot rest," he said.
