In recent years ISM bands have also been shared with (non-ISM) license-free error-tolerant communications applications such as wireless sensor networks in the 915 MHz and 2.450 GHz bands, as well as wireless LANs and cordless phones in the 915 MHz, 2.450 GHz, and 5.800 GHz bands. Because unlicensed devices are required to be tolerant of ISM ...
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
It had 0–10 mR/hour range with external probe and headphones. This was designed to use two 150 volt batteries, although later they were fitted with a vibrator power pack which used four 1.35 volt mercury cells or, alternatively, a mains electricity power pack. Many of these units remained in service until the 1980s.
The generator contains the strontium-90 radioisotope, with a heating power of 250W and 1,480 TBq of radioactivity – equivalent to some 280 grams (9.9 oz) of Sr-90. [4] Mass-scale production of RTGs in the Soviet Union was the responsibility of a plant called Baltiyets, in Narva , Estonia .
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 ...
The EuroPowerPack is the combination of the MTU MT883 Ka-500/501 diesel engine delivering over 1100 kW (1500 PS) shaft power with the ten-speed (five forward, five reverse) Renk HSWL 295TM automatic transmission for the use in heavy tracked vehicles like tanks.
Powerpack removal of an M75 APC. A powerpack or power pack is a part of a modular powertrain that contains some type of engine (most frequently an internal combustion engine, but other types, including electric motors, are possible) and may also contain a transmission and various supporting components.
A radionuclide generator is a device which provides a local supply of a short-lived radioactive substance from the decay of a longer-lived parent radionuclide. They are commonly used in nuclear medicine to supply a radiopharmacy . [ 1 ]
