In United States patent law, an inter partes proceeding to determine the priority issues of multiple patent applications; a priority contest
Unwanted radio signals received by a radio telescope that originate in human activity rather than natural phenomena
Making body contact with an opponent who does not have possession of the puck Interference is also called when a player is standing in the crease or otherwise makes contact with the goaltender
Undesirable signals which interfere with the normal operation of electronic equipment or electronic transmission
Any electromagnetic phenomenon, signal or emission, man-made or natural, which causes or can cause an undesired response, malfunctioning or degradation of performance of electrical or electronic equipment
Any extraneous energy, from natural or manmade sources, that impedes the reception of desired signals The interference may be constructive or destructive, resulting in increased or decreased amplitude, respectively
(1) The superposing of one wave on another (2) The mutual effect of two beams of light, resulting in a reduction of energy in certain areas and an increase of energy in others
The act or state of interfering; as, the stoppage of a machine by the interference of some of its parts; a meddlesome interference in the business of others
(American football) the act of obstructing someone's path with your body; "he threw a rolling block into the line backer"
Disturbance of an electrical, electromagnetic or RFI nature that introduces undesirable responses into other electronic equipment
The overlapping or collision of two or more waves Waves move through each other, but while they overlap they can make a larger disturbance if their amplitudes are the same (constructive interference) or will make a smaller disturbance if their amplitudes (destructive interference) Click to see a constructive interference movie Click to see a destructive interference movie Back to Top Back to Wave Index
Energy which tends to interfere with the reception of the desired signals, such as fading from airline flights, r-f interference from adjacent channels, or "ghosting" from reflecting objects such as mountains and buildings
1 Extraneous signals, noises, etc that hinder proper reception of the desired signal in electronic equipment See babble, clutter, cosmic noise, crosstalk, jitter, static
disapproval Interference by a person or group is their unwanted or unnecessary involvement in something. Airlines will be able to set cheap fares without interference from the government
An act by a fielder which hinders a players attempt to hit a pitch or an act by a member of the team at bat that impedes a fielder attempting to make a play
An interferent is any gas other than the target gas that will cause a gas detecting sensor to give a signal In the case of a combustible sensor, any combustible gas or vapor will cause a signal
The suppression of crossing over that occurs in the extended chromosomal vicinity of an initial crossover event Interference is responsible for a severe reduction in the expected frequency of double crossover events in ten to twenty centimorgan lengths of the genome (see Chapter 7)
An effect caused by the superposition of two systems of waves, such as a distortion on a broadcast signal due to atmospheric or other effects
