As well as allowing the programmer to save and load programs, blocks of memory or screen images into the RAM disc and catalogue the contents of the RAM disk, Beta BASIC also provided commands for the creation and use of arrays held in the RAM disk, allowing programs running in the 30 KB or so of free memory on the Spectrum to manipulate arrays ...
TR-DOS is a disk operating system for the ZX Spectrum with Beta Disc and Beta 128 disc interfaces. TR-DOS and Beta disc were developed by Technology Research Ltd (UK), in 1984. [ 1 ] [ 2 ] A clone of this interface is also used in the Russian Pentagon and Scorpion machines.
IEC 61131-3 is the third part (of 10) of the international standard IEC 61131 for programmable logic controllers.It was first published in December 1993 [1] by the IEC; the current (third) edition was published in February 2013.
Anti-Multiface was a public domain program for the Amstrad CPC which allowed the restoring of saved memory dumps without the need for a Multiface to be present. It was limited to 128K machines and would not work on dumps bigger than 64K. The program was developed by Serge Querne but credited to "Merlin J. Bond of Magic Software".
The program was designed to make Z80 machine code programming easier, [1] with full symbolic instructions, and an editing style similar to the Spectrum's built-in BASIC. Zeus Assembler was later re-released by the manufacturer of the ZX Spectrum, Sinclair Research. A Commodore 64 version was released in 1984. "Zeus 64 Assembler".
Infrared remote control for the analog SLR camera Canon EOS 100 from 1991. Remote controls are used in photography, in particular to take long-exposure shots. Many action cameras such as the GoPros [45] as well as standard DSLRs including Sony's Alpha series [46] incorporate Wi-Fi based remote control systems. These can often be accessed and ...
Direct-sequence spread-spectrum transmissions multiply the symbol sequence being transmitted with a spreading sequence that has a higher rate than the original message rate. Usually, sequences are chosen such that the resulting spectrum is spectrally white. Knowledge of the same sequence is used to reconstruct the original data at the receiving ...
Spectrum management is a growing problem due to the growing number of spectrum uses. [6] Uses include: over-the-air broadcasting, (which started in 1920); government and research uses (which include defense, public safety—maritime, air, police—resource management, transport, and radio astronomy); commercial services to the public (including voice, data, home networking); and industrial ...
