Frequency-hopping spread spectrum ( FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver. FHSS is used to avoid interference, to prevent eavesdropping, and to enable code ...
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely operate a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of model ...
Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...
У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control ( AFC ), also called Automatic Fine Tuning ( AFT ), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It is primarily used in radio receivers to keep the receiver tuned ...
Kakashi Hatake ( Japanese: はたけ カカシ, Hepburn: Hatake Kakashi) is a fictional character and one of the main protagonists in the Naruto manga and anime series created by Masashi Kishimoto. In the story, Kakashi is the teacher of Team 7, consisting of the series' primary characters, Naruto Uzumaki, Sasuke Uchiha, and Sakura Haruno.
A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; [1] these elements are most often metal rods (or discs) acting as half-wave dipoles. [2] Yagi–Uda antennas consist of a single driven element connected to a radio transmitter or receiver (or ...
Ink on paper, 9 1⁄4 × 8 1⁄8 " (23.5 × 20.6 cm). Museum of Modern Art, New York. Surrealist automatism is a method of art-making in which the artist suppresses conscious control over the making process, allowing the unconscious mind to have great sway. This drawing technique was popularized in the early 1920s, by Andre Masson and Hans Arp.
Josh Klinghoffer, a guitarist who has played with Pearl Jam and the Red Hot Chili Peppers, was distracted by a cellphone while he was behind the wheel of an SUV that struck and killed a pedestrian ...
