what did J.P Knight invent?
The first known traffic signal appeared in London in 1868 near the Houses of Parliament. Designed by JP Knight, it featured two semaphore arms and two gas lamps. The earliest electric traffic lights include Lester Wire's two-color version set up in Salt Lake City circa 1912, James Hoge's system (US patent #1,251,666) installed in Cleveland by the American Traffic Signal Company in 1914, and William Potts' 4-way red-yellow-green lights introduced in Detroit beginning in 1920. New York City traffic towers began flashing three-color signals also in 1920.
'JP-7', where JP stands for 'Jet Propellant' is a jet fuel for the use in supersonic aircraft because of its high flash and thermal stability. For example in SR-71,because of the high temp. environment in which the engine operates, it uses low volatile JP 7 jet fuel which requires a chemical ignition system.
JP-8 is a fuel specified by the United States Air Force in MIL-DTL-83133E that boil in the range of 186°C (10% boiling point) to 300°C (final boiling point) using the ASTM D2887 test method. The density of JP-8 ranges from 0.775-0.840 kg/L.
The Z80's rotate-with-carry instructions, RRC and RLC, for Rotate Right and Rotate Left, are great for taking action based on individual bits being set or cleared. If you start with a clear carry flag, then get a byte from wherever, then you can rotate left or right one bit at a time. The bit you want to examine will eventually be in the carry. Then, execute a JP C, (location) or JP NC, (location) to jump based on whether or not the bit is set. (Of course, you could also use JR). The beauty of RLC and RRC is that they don't destroy the byte that you are using - after doing enough rotates, the byte will be as it was before.
Only in marketing. Had he achieved his goal , most of our homes would be powered with DC electricity, instead of AC electricity, according to many historians. Improvement for all: The answer given above is completely wrong. Tesla was a master of AC current and found a way to transmit AC current without wires. If his arch-nemesis Edison had successfully done something other than nothing with DC current, we would be living in a DC current world. The fact that almost everything on earth runs on AC electricity is probably Tesla's greatest SUCCESS. The failure was his lack of forethought in presenting a FREE energy distribution system to money hungry corporate capitalists. They discovered that Tesla's work could put them (specifically JP Morgan) basically out of the energy business, as over the air energy can't be regulated or metered.

The traffic light, as we know it today, actually went through a few phases of invention.1868 - JP Knight created a signal based on red and green gas lamps. It took an officer to operate it. It exploded about one month later and injured the officer on duty.1912 - Lester Wire invented the first electric traffic light. It was also based off of the red and green system.1914 - James Hoge improved upon the system by adding a buzzer to notify drivers that the light would soon be changing colors.1920 - William Potts made a four way signal. Potts replaced the buzzer with a yellow light.1923 - Garrett Morgan added a mechanical linkage to allow officers to operate the signal from a distance.
