Spektrum refers to their technology as "Digital Spectrum Modulation." Each transmitter has a globally unique identifier (GUID), to which receivers can be bound, ensuring that no transmitter will interfere with other nearby Spektrum DSMx systems. The Spektrum system is also one of the manufacturers which offers "Model Match" in which the ...
The MC-10 includes a BASIC interpreter in ROM and uses regular audio cassettes for bulk storage. Text and graphics are displayed on a television set via a built-in RF modulator. Less common for machines in its class is the integrated RS-232 serial port, which allows the MC-10 to use line printers and modems without additional hardware.
The two-rays ground-reflection model is a multipath radio propagation model which predicts the path losses between a transmitting antenna and a receiving antenna when they are in line of sight (LOS). Generally, the two antenna each have different height. The received signal having two components, the LOS component and the reflection component ...
The solution found by a number of researchers was to use two resonant circuits in the transmitter, with their coils inductively (magnetically) coupled, making a resonant transformer (called an oscillation transformer); [11] [46] [17]: p.352-353, 355–358 this was called an "inductively coupled", "coupled circuit" [45] or "two circuit" transmitter.
R1155 Receiver on top of a T1154 Transmitter. The wireless operator on an Avro Lancaster speaking to the pilot from his position in front of the Marconi T1154/R1155 transmitter/receiver set, circa 1943 Inspection of an R1155. The R1155 was a British communications receiver, commonly used in aircraft along with its associated T1154 transmitter
They made a new version of the HT-4, which was known as the BC-610 transmitter, a part of the SCR-299 mobile communications unit, and production began in 1942. General Dwight Eisenhower credited the SCR-299 in the reorganization of U.S. forces, which led to their victory against the Nazis at Kasserine Pass .
NX, formerly known as "Unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens Digital Industries Software. [1] [2] In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX.
The 9K35 Strela-10 (Russian: 9К35 «Стрела-10»; English: arrow) is a Soviet highly mobile, short-range surface-to-air missile system. It is visually aimed, and utilizes optical/ infrared-guidance.
