i've worked on a similar product before.
there's no way they were turning a profit. they definitely missed stuff all the time even with a ton of sensors. and sensors aren't the only cost. annotation is by far the most costly operational expense. new product? needs several annotated photos and recalibrated weight sensors. merchant decides to put Christmas branding on the same UPC? now all your vision models are poisoned for that product. it needs to be re-annotated for the month and a half it exists and the models need to be swapped out once inventory changes over again. as long as merchants are redesigning products (always) your datasets will be in a constant state of decay. even if your vision sensors are stationary and know the modular design up front, you still need to be able to somewhat generalize in case things get misplaced (big problem for weight sensors) or the camera gets bumped.
between dataset management, technology costs, research costs, rote operational costs, etc this is a very expensive problem to solve. and large models with a ton of parameters are little help; they may lower annotation costs a bit but will increase the cost of compute.
once i really dug into this problem i saw Amazon Go's Just Walk Out for what it really was: a marketing stunt
Why are they even in business yet?
construction equipment for park improvements (backhoe, etc)
gas powered moped
electric moped
gas powered rc car
4-wheeler/atv/dune buggy
golf cart
segway/monowheel
antique cars for some kind of demo/event
shriner guys in those mini cars in a local parade (at least i think most americans know what i'm talking about)
anti-drunk driving display (they have these sometimes at colleges, and maybe high schools, but it's basically a wrecked car and there are police there to do pr)
Note: i think many of your options are just clearly not covered by the rule, maybe keep some of them but not so many?
I have been absolutely loving wearing these in colder, drier weather. Its an extremely minimal shoe- feels like being barefoot, They are too warm for warmer weather and they absorb water is wet weather. I dealt with wet weather by using sealskinz waterproof socks. I bought two sizes: a smaller size for just my foot and a bigger size to accommodate socks.
It’s so weird. Some things are not business opportunities. If people are feeling lonely because society is a mess, that’s not a business opportunity. That’s a social issue that should be solved.
I lived in an area that had under-controlled poison ivy overgrowth, and it was always a challenge to convince people that poison ivy can look differently than what's expected once it's developed unimpeded for years.
