The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]
Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand. [ 2 ] Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio , ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network , optical ...
Watch the Video. Click here to watch on YouTube. Many animals engage in elaborate mating rituals. For flight-ready birds, these often involve complex dance moves and peacock-like displays of grandeur.
Angles are measured by the transceiver, which contains an array of transducers. The transceiver head normally contains three or more transducers separated by a baseline of 10 cm or less, hence the "short baseline" name. A method called “phase-differencing” within this transducer array is used to calculate the direction to the subsea ...
The horse really wanted to get up close and personal with the donkey in the footage.Who could blame him? The baby donk was positively precious. He looked like something out of a movie.
Jenna Bush Hager, Savannah Guthrie, Sheinelle Jones and their kids celebrated the holidays together at a recent party at the White House.
One of the starting points in these studies is the mounting of heat flux sensors on walls in existing buildings or structures built especially for this type of research. Heat flux sensors mounted to building walls or envelope component can monitor the amount of heat energy loss/gain through that component and/or can be used to measure the ...
