Folding table. General use Folding Table. A folding table is a type of folding furniture, a table with legs that fold up against the table top. This is intended to make storage more convenient and to make the table more portable. Many folding tables are made of lightweight materials to further increase portability.
Slide rule. Typical ten-inch (25 cm) student slide rule (Pickett N902-T simplex trig) A slide rule is a hand -operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry.
Folding machine. A folding machine is a machine used primarily for the folding of paper. Folding is the sharp-edged bending of paper webs or sheets under pressure at a prepared or unprepared bending point along a straight line according to specified dimensions and folding layouts. [ 1 ] Paper can be folded with either a buckle or a knife; thus ...
A Tip-top table is a folding table with the tabletop hinged so it can be placed into a vertical position when not used to save space. It is also called tilt-top table, tip table, [1] snap table [2] [3] some variations are known as tea table, loo table. These multi-purpose tables were historically used for playing games, drinking tea or spirits ...
A folding hash code is produced by dividing the input into sections of m bits, where 2 m is the table size, and using a parity-preserving bitwise operation such as ADD or XOR to combine the sections, followed by a mask or shifts to trim off any excess bits at the high or low end. For example, for a table size of 15 bits and a 64-bit key value ...
Code folding. Code or text folding, or less commonly holophrasting, [1] is a feature of some graphical user interfaces that allows the user to selectively hide ("fold") or display ("unfold") parts of a document. This allows the user to manage large amounts of text while viewing only those subsections that are currently of interest.
In signal processing, the Nyquist frequency (or folding frequency), named after Harry Nyquist, is a characteristic of a sampler, which converts a continuous function or signal into a discrete sequence. For a given sampling rate (samples per second), the Nyquist frequency (cycles per second) is the frequency whose cycle-length (or period) is ...
The scissor mechanism is a mechanical linkage system used to create vertical motion or extension. It consists of a series of interconnected, folding supports that resemble the shape of a pair of scissors, hence its name. The scissor mechanism is widely employed in various applications, including scissor lifts, folding tables, adjustable height ...
