content: I know there's a fair share of budding inventors here that build things for fun but, for those that actually want to take this sort of thing more seriously and hope to make things better for everyone or simply to revolutionise basic concepts, what would you create?For me, I would invent an alternative for taking blood pressure, particularly one that doesn't have to squeeze one's arm to take it (as to me causes discomfort, and at times can give inaccurate readings even from the patient making slight motion).I've recently thought of it of having a large ring-like design where it can adjust to the circumference of the patient's upper arm like for the basic cuff but instead of having it squeeze the arm to get the readings (and the pulse included), I'd have it "read" the systolic and diastolic levels instead, although that may sound impractical. I'd think more thought would have to be put on that should it be a successful product...So, what about you?

"Blood pressure monitors" fall into the medical device category, so need to be FDA-approved before one can sell them in the US.They probably could still sell them as a gadget, but if they intend to market them as true blood pressure monitors, that would ruin their marketing. They could even get in trouble for that, as even if not sold as blood pressure monitors, the fact they provide blood pressure measurements could mislead customers. So, yeah.

Patent office fees are a fraction of that, including maintenance fees for the first few years:https://www.uspto.gov/learning-and-resources/fees-and-payment/uspto-fee-scheduleWhether it's advisable to draft a patent application without a patent attorney is a different question. I'd say if you have read and analysed a good number of patents before, and discuss your own invention with a trusted third party to "take a step back" when describing it, you can do it yourself.

content: A truly economical and therefore ECO-FRIENDLY energy source for all. By that I mean one that would actually cost less than the ones available today. And by "cost less" I mean when EVERY cost is included including things like government or private subsidies. Those subsidies are just hidden costs that we all pay for anyway.And the cost in dollars or whatever currency is a true measure of how eco-friendly things actually are. Lower cost = less resources used = more eco-friendly.Such an energy source should be affordable, build-able, and maintainable by EVERYONE. No more electric bills. No more gas bills. Etc. You build it and it powers your house, your vehicles, your boat or plane, etc. And I would immediately put it in the public domain so there would be no fees for building it. My gift to the world.Do I dream? Sure I do. But the question was, "What would youliketo invent?" So I dream BIG! And I will leave the improved blood pressure cuffs to others. They obviously don't need to monitor their blood sugar which requires sticking a hole in yourself every time.

content: Your were talking about theUS patent process(only) in the earlier post, right? Much lower application and examination fees, especially for small entities and sole inventors.Sure, the maintenance fees climb over time. That's deliberate, to discourage people from maintaining a patent even if they don't commercialize it, blocking others from using the technology. If you decide to maintain the patent for many years, that should be based on the fact that you generate significant income from it.

It would be a flat board that you would place anywhere you like - on the ground, for example - and it would shield everything above it from the earth's gravity. So everything directly above the board would be weightless. Very useful.You could also use it as the heart of a perpetual motion machine: suspend a bicycle wheel so half of it is over the board. The weightless half will rise as the heavy half falls, rotating forever. Doesn't have to be anactualbicycle wheel, obvs.

content: I worked on a PPG sensor many years ago. It was designed to detect deep vein thrombosis in the lower legs. Place the sensor just above the ankle bone and pump your foot up and down about 10 times. This pushes the blood up into the upper part of the leg and then measure the time it takes for the lower leg to "re fill". If it takes about 10 seconds or so then all is OK. If it only takes a few seconds then it means the valves in the vein are not working ie thrombosis and usually the vein has to be bypassed.Don't ever remember the application of PPG ever being used as a means of measuring blood pressure.

What is more intriguing is that if you use 6 colours of LED, instead of just 2, you can measure the percentage of total hemoglobin cells which are oxygenated (SaO2), rather than the percentage of available hemoglobin cells which are oxygenated (SpO2). The two readings are almost the same for a healthy person, but for some sick people, and for heavy smokers, some percentage of the hemoglobin cells are fouled up with pollutants, and cannot be oxygenated.

It is however highly invasive—they insert an arterial line (artline; a thin plastic tube inserted after inserting a needle with the help of ultrasound) into an artery, and can measure the actual blood pressure continuously. The blood pressure on the monitor screen is updated every heartbeat.

Piece of over priced shit!You would think they would test it, and put a handle on it, instead of shipping some generic bare cutting that is just bearly functional (works on ~50% of the crimps you try it on).Like, test the.... 5000% profit margin thing you specify .

content: Ant Repellant micro-surfaces.Hi, I'm cautious about this one, along the lines of ICE-9, a mythical molecule that made for an unstoppable sweep, of all the oceans into a high temperature form of solid H2O.The invention would appear to be a kind of FURRY surface, very pointy on the smaller scales, and thus an impalement hazard to any ant attempting to walk on it.Advantage: no poisonous pesticides...at least at first glance.Disadvantage: You certainly would want to have control over it's application and prohibit a type that could self-grow over time. The stuff could ruin a whole lake, or...even a whole ocean (likely bad).You can imagine the production would be a mat having imbedded fibers that are sharp and hardened. It would have to resist any ant that starts over the pad, or floor surface.Now, I haven't considered the occasional large ant that is in the mix, of little workers. I'm not sure if those are Ant Police ?You might lift up some board, in the yard, and observe an occasional big ant, maybe called a SENTRY, I'll have to check.Many folks don't like the spray poisons when treating for a highly mobile ant pack, roaming the food counter.But that pointy and knife-like blade style might be rendering the mat as highly toxic, to the environment, I could see that.

content: Thanks for question.The stress level, in private is bad but tolerable. However, my current cash flow situation means that I live as a room boarder, ait like a roommate, and here I have more than usual, legal room rentals. The yard is very enjoyable and I have a limited but good kitchen use access.It's the landlord freaking out about ants everywhere that's not good.My mental picture is of an individual ant that gets cut, just by trying to walk. Somewhat along the lines of sticky pads. So first concern is whether or not a micro-blade would have enough force, to f××× up every individual, a lot.But doing well on the lethal effect means a need for caution, in environmental safety. That may might harm things / animals that were not considered.I've seen how ants will grab small items and take them somewhere. (See Roblers nano Nerf Gun video). That might mean that a fragmented mat could end up in pieces in ground burrows or in water ways.I'd be advocating to study the hell out of some invention like that 'death Mat' I've cooked up.The unintended consequences risk is up there.With caution and better materials a no-pass mat could still be beneficial, as it lacks the typical deliberate toxins content.An ant foot print doesn't have much force, either.

content: I think there's room in the market for an improved kill-a-watt style watt meter. I think I'd integrate it into a power strip. Average Joe home-owners need a better way to measure and manage power usage, including very low level "vampire" and "phantom" levels of power drain from media equipment.The cheaper designs are pass-through sockets, fail to measure low power levels, and sometimes catch fire.

content: Quote from: RJSV on October 26, 2024, 07:50:56 pmGuess what: we already have that. It's called diatomaceous earth. Really cool stuff. (I used to sell it when I worked at a hardware store.)What this is is the exoskeletons of microscopic critters called diatoms that live in seawater. When they die and drift to the bottom, their bodies accumulate and eventually their soft parts rot away, leaving a very hard and very sharp and spiny skeleton. This "earth" is harvested in places where it's accessible.It's a very fine white powder that you apply to places where you have insect pests. The insects crawl over it and it cuts their bodies with all those sharp edges, and the insects die of dehydration. Totally nontoxic: you could eat it and it wouldn't hurt you at all. (It's just silica.)You should try it if you have any annoying insect infestations.

content: Quote from: Analog Kid on October 31, 2024, 01:14:45 amExcept for the fact that the word "blood" appears in both, measuring blood pressure really has nothing to do with Theranos' claimed biological assays on a small blood sample.Also, optical blood pressure measurement is real, although certainly not perfect yet. A 2022 assessment of the Samsung Galaxy Watch 2 (released in 2019) concluded that the measurements were not accurate enough for clinical use, but certainly not "snake oil":https://pubmed.ncbi.nlm.nih.gov/35898281.The Galaxy Watch 5 Pro, released a few years later, supposedly does a significantly better job, but requires monthly calibration. I could not find a peer-reviewed assessment of that more recent implementation in a quick search though.
