Acta Mechanica is a peer-reviewed English, scientific journal publishing articles in the field of theoretical and applied mechanics, specifically in solid mechanics and fluid mechanics, published by Springer. The editor-in-chief is Hans Irschik (Johannes Kepler University Linz). [1]
A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer. The first public ...
An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.
HP-86B with 9121 dual diskette drive. The first model of the Series 80 was the HP-85, introduced in January 1980. [1] BYTE wrote "we were impressed with the performance ... the graphics alone make this an attractive, albeit not inexpensive, alternate to existing small systems on the market ... it is our guess that many personal computer experimenters and hackers will want this machine."
Case closed. The HP 200LX Palmtop PC (F1060A, F1061A, F1216A), also known as project Felix, is a personal digital assistant introduced by Hewlett-Packard in August 1994. [1] [2] It was often called a Palmtop PC, and it was notable that it was, with some minor exceptions, a DOS-compatible computer in a palmtop format, complete with a monochrome graphic display, QWERTY keyboard, serial port, and ...
The HP Integral PC (or HP 9807A) is a portable UNIX workstation computer system produced by Hewlett-Packard, launched in 1985 at a price of £5450. [1] It utilizes the Motorola 68000 microprocessor (running at 8 MHz) and ran the HP-UX 1.0 operating system .
HP 9815A. Chronologically, the models of the family were: HP 9810A, a keystroke programmable computer with magnetic cards and LED display, introduced in 1971, [1]; HP 9820A, introduced in 1972, was the first HP model that deals with algebraic input (not only RPN) [2] featured a high level language simpler than BASIC that was later named high performance language (HPL),
HP-150 II (aka HP 45849A) [6] replaced HP-150 in 1984. While still called HP Touchscreen II , the touchscreen was no longer standard, but rather a rarely adopted option. The optional touchscreen bezel was superior to the original bezel, in that the emitters and detectors were now located behind a solid infrared-transparent plastic; thus ...
