The difference between a drought and a famine is down to man. Texas is in the middle of its worst drought on record right now but cowboys arenât starving â because Texas, and the US, have government and economy enough to ensure they donât.
Incremental Encoders. An encoder is an electrical mechanical device that converts linear or rotary displacement into digital or pulse signals. The most popular type of encoder is the optical encoder, which consists of a rotating disk, a light source, and a photo detector (light sensor).The disk, which is mounted on the rotating shaft, has patterns of opaque and transparent sectors coded into the disk (see Figure 1).he most popular type of encoder is the optical encoder, which consists of a rotating disk, a light source, and a photo detector (light sensor).

An encoder is a sensor of mechanical motion that generates digital signals in response to motion. As an electro-mechanical device, an encoder is able to provide motion control system users with information concerning position, velocity and direction.There are two different types of encoders: linear and rotary.A linear encoder responds to motion along a path, while a rotary encoder responds to rotational motion.s an electro-mechanical device, an encoder is able to provide motion control system users with information concerning position, velocity and direction.
