A ladder without rungs.
This ladder uses the batteries from your power tools to power the ladder up and down. The ladder has only one rung that you stand on, and it goes up and down by pushing the button on the handle that you hold, or it could be controlled by your foot.
The demand for miniature devices is big and growing quickly. Smaller devices are lighter, faster, use less power and consume fewer resources. They have enabled wearables, point of care diagnostics, IoT devices, and the aerospace industry.
But methods for making these devices are slow and expensive.
Conversely, 3D printing,
LED video displays are a $15B market. It is also the last passive-matrix video device in production. The existing process uses discrete LEDs on conventional PCBs. With a passive backplane, all the image artifacts, 
HOW THE ENTRY WORKS
The large vehicle passing maneuver assistance device (LVPMAD) is designed to assist motorists to safely pass a large vehicle. The LVPMAD processors would track the speed of the large vehicle, location and speed of the passing vehicle. Inclinometer would determine road grade (which drastically affects braking distance),
The availability of high-performance Commercial Off-The-Shelf (COTS) electronics that can withstand Low Earth Orbit conditions has opened an avenue for wide deployment of CubeSats and small-satellites. Swarms of these small satellites offer whole new capabilities in Earth observation, global positioning and communication compared to a large monolithic spacecraft.
For 30 years lean combustion has been known to lower NOx emissions and many programs outline its benefit and in its Tapps II Combusor final report submitted by GE for its GEnx Engine in 2013 it shows zero fractal components. If things are the same, a small but important change can be made.
This IoT tool has for objective to quantify for a specific period, all the costs involved during the operation and maintenance of on grid streetlights based on LED or conventional technologies.
The occurrence of wounds or deep injuries in patients located in very distant places, places in conflict or even, in outer space, where the transportation of the patient can be very complicated or it can take days to carry the patient to an attention place, generates risk for lives of people located in these places or circumstances.
This project is about doing an experiment on circulation of light. It is known that mirrors can reflect light and there is a device called the periscope used for this purpose. The mirrors of a periscope are fixed 45 degrees to reflect light.
