True RMS provides a more correct value that is proportional to the square root of the average of the square of the curve, and not to the average of the absolute value. For any given waveform , the ratio of these two averages is constant and, as most measurements are made on what are (nominally) sine waves, the correction factor assumes this ...
HP LaserJet 4. The HP LaserJet 4 (abbreviated sometimes to LJ4 or HP4) is a group of monochrome laser printers produced in the early to mid-1990s as part of the LaserJet series by Hewlett-Packard (HP). The 4 series has various models, including the standard LaserJet 4 for business use, the 4L for personal use and the 4P for small businesses. [1]
A reconfigurable manufacturing system (RMS) is a system invented in 1998 that is designed for the outset of rapid change in its structure, as well as its hardware and software components, in order to quickly adjust its production capacity and functionality within a part family in response to sudden market changes or intrinsic system change.
Laser head from HP LaserJet 5L printer. Most HP LaserJet printers employ xerographic laser-marking engines sourced from the Japanese company Canon.Due to a tight turnaround schedule on the first LaserJet, HP elected to use the controller already developed by Canon for the CX engine in the first LaserJet.

Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing work. Apparent power is the product of root mean square (RMS) current and voltage. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of ...
PCL 5 was released on the HP LaserJet III [2] in March 1990, adding Intellifont font scaling (developed by Compugraphic, now part of Agfa), outline fonts and HP-GL/2 (vector) graphics. PCL 5e (PCL 5 enhanced) was released on the HP LaserJet 4 [ 2 ] in October 1992 and added bi-directional communication between the printer and the PC and Windows ...
Record Management Services (RMS) are procedures in the VMS, RSTS/E, RT-11 and RSX-11M operating systems that programs may call to process files and records within files. [1] [2] Its file formats and procedures are similar to of those in some IBM access methods [a] for several of its mainframe computer operating systems [b] and by other vendors for file and record management.
RMS 2011 was released in May 2011. RMS 2011 included more new features than any previous RMS version and provided modellers with enhancements to the seismic architecture to allow direct reference between the reservoir models and the 3D and 4D seismic data that the interpretation and modelling is based on. Key highlights of RMS 2011 included new ...
