Blinkenlights on the NSA's FROSTBURG supercomputer from the 1990s Typical LED pattern of a Thinking Machines CM-5. The Connection Machine, a 65 536-processor parallel computer designed in the mid-1980s, was a black cube with one side covered with a grid of red blinkenlights; the sales demo had them evolving Conway's Game of Life patterns.
"Wynken, Blynken, and Nod" is a poem for children written by American writer and poet Eugene Field and published on March 9, 1889. [citation needed] The original title was "Dutch Lullaby".
Fluorescence intermittency, or blinking, is the phenomenon of random switching between ON (bright) and OFF (dark) states of the emitter under its continuous excitation.It is a common property of the nanoscale emitters (molecular fluorophores, colloidal quantum dots) related to the competition between the radiative and non-radiative relaxation pathways.
Epson also bundled the Software Installation Program which was a patch kit to remove the EPSON check. Both machines were received well due to their reasonable prices and better compatibility. [27] In 1988, Epson made annual sales of 200,000 units and successfully established PC-98 clones in the Japanese PC market. [31]
The basic signal consists of flashing red lights, a crossbuck and an alarm (either a bell, a speaker that mimics a bell sound or an electronic siren), attached to a mast. At most crossings, the signals will activate about 30 seconds before the train arrives but there are sensors measuring speed so that the crossing knows when to activate; so ...
Flashing (weatherproofing), construction material used to prevent the passage of water around objects; Flash evaporation, causing evaporation by lowering a fluid's pressure below its vapour pressure; Flashing light, such as a light bulb or computer's cursor
NWAS ambulance displays the operation of a wig-wag: only one headlight operates at a time, with the two flashing alternately at a preset rate. A wig-wag is a device for flashing an automobile's headlamps, in its simplest form, so only one of the two headlights operates at a time, with the two flashing at a preset rate. In its traditional form a ...
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
