Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...
An encoder is a sensor which turns a position into an electronic signal. There are two forms: Absolute encoders give an absolute position value. Incremental encoders count movement rather than position. With detection of a datum position and the use of a counter, an absolute position may be derived.
A linear encoder is a sensor, ... Multiple, equally spaced reference marks may also be placed onto the scale such that following installation, the desired marker can ...
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic.
An interactive electronic technical manual (IETM) is a portal to manage technical documentation. IETMs compress volumes of text into just CD-ROMs or online pages which may include sound and video , and allow readers to locate needed information far more rapidly than in paper manuals.
The concept of SSTV was introduced by Copthorne Macdonald [1] in 1957–58. [2] He developed the first SSTV system using an electrostatic monitor and a vidicon tube.It was deemed sufficient to use 120 lines and about 120 pixels per line to transmit a black-and-white still picture within a 3 kHz telephone channel.
A short video explaining the concept of video codecs. A video codec is software or hardware that compresses and decompresses digital video.In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.
