Ten years ago, we wrote about Six Degrees of Wikipedia, a cute web page that would find the link path between any two Wikipedia pages. The transformation of instrumentation from mechanical pneumatic transmitters, controllers, and valves to electronic instruments reduced maintenance costs as electronic instruments were more dependable than mechanical instruments. This is the basis for Coulomb's law, which states that, for stationary charges, the electric field varies with the source charge and varies inversely with the square of the distance from the source. 1972-75 - SDM3 electronic distance meter, the LTS20 laser theodolite, the DT0306 electronic digital theodolite and TM1A one-second theodolite T is the time period λ is the wavelength.

The Electronic Distance Meter uses electromagnetic waves to measure the distance. Propeller-type current meters (similar to the purely mechanical Ekman current meter, but now with electronic data acquisition) can be traversed over the area of the penstock and velocities averaged to calculate total flow. Other types of indicator include mechanical devices with cantilevered pointers and electronic devices with digital displays. The technologies, listed in the table below, differ in the distance over which they can transfer power efficiently, whether the transmitter must be aimed (directed) at the receiver, and in the type of. This imposes transmission problems on systems spread out in a room or on systems that require remote measurements. When the target is within nominal range, the device lock screen user interface will appear, thus emerging from what is known as sleep mode. Used electronics are the quickest-growing source of waste and can have serious health impacts.
