Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
A sensor node, also known as a mote (chiefly in North America), is a node in a sensor network that is capable of performing some processing [1], gathering sensory information and communicating with other connected nodes in the network. A mote is a node but a node is not always a mote.
ANT was designed for low-bit-rate and low-power sensor networks, in a manner conceptually similar to (but not compatible with) Bluetooth Low Energy. [3] This is in contrast with normal Bluetooth , which was designed for relatively high-bit-rate applications such as streaming sound for low-power headsets.

The most common type is a two-channel sensor that scans a toothed wheel on the motor shaft or gearbox which may be dedicated to this purpose or may be already present in the drive system. Modern Hall effect sensors of this type make use of the principle of magnetic field modulation and are suitable for ferromagnetic target wheels with a module ...
In June 1999, George Lucas announced that Episode II of the Star Wars Prequel Trilogy would be the first major motion picture to be shot 100% digitally. Sony and Panavision had teamed up to develop the High Definition 24p camera that Lucas would use to accomplish this, and thus the first CineAlta camera was born: the Sony HDW-F900 (also called the Panavision HD-900F after being "panavised").
