Initially, both outputs of a latch are at Logic 1. If the “X” input to a display is switched to OV, current flow is from the positive rail via the four corner- mounted l. If a “O” input to a display is switched low, current flow is via the corner l.
The resistor is selected to limit current to 10 mA. Lasers Again Readers may remember the fuss over using lasers as part of London’s Christmas decorations last year.
74LS IC QUAD BUS TRANSRECEIVER — Majju
Apparently some thought the beams would constitute a hazard. In the American town of Atlanta they’ve been using lasers for some time to control traffic lights. Before anyone sees “red “, the health hazard is virtually nil and the system has been given a fond, approving kiss by the US Bureau of Radiological Health Standards as being “safe for eyes “.
Previously, the digital computer that controls the city’s traffic lights was coupled to the lights via telephone lines, or by dedicated cables. The system can control up to separate road junctions. At each set of lights is an optical transceiver that faces its neighbour at another junction.
Sensors, in the road, monitor the traffic density and this information is fed back along the laser chain to the computer. The digital computer “cornputes” all this information and, having computed sends a master command signal to the relevant traffic lights. In a good, clear, typical English summer’s day singular!
Peak power outputs of the GaAs laser diodes used are around 10W, datashest these are pulsed at 2kHz. A shining example to traffic light manufacturers everywhere. Thermometers For those with an interest in electronic thermometers, keep an eye open for the magic number AD And it’s only “transistor size” being housed in a standard TO can.
Better still, there are only two leadout wires. During manufacture, the resistive elements are precision laser trimmed to precise values. The result is a sensor that is linear over the range.
So much so that you can plug in different ones without any need to recalibrate. For the technical buffs, the output is The cheapest version costs barely the equivalent of a single British quid.
