Semaphore, английский
- Семафор
- An expeditious mode of communication by signal; it consists of upright posts and movable arms, now chiefly used for railway signals, electric telegraphs being found better for great distances.
- A signaling system in which a pair of hand-held flags or lever-operated wooden arms are placed in various positions to indicate numbers and letters of the alphabet. the intention to send a message by semaphore is signaled to the receiver by the triple flag hoist “yz1” or at close range by the semaphore letter “j” (left hand out to the side and right hand above the head, forming a right angle).
- In programming, a signal—a flag variable—used to govern access to shared system resources. a semaphore indicates to other potential users that a file or other resource is in use and prevents access by more than one user.
Semaphore indicator, английский
Vehicle direction indicator consisting of an arm on the side of the vehicle that can be manually or automatically raised and lowered. see trafficator. semi
Semaphore signals, английский
Signals usually worked mechanically by wire from a signal box’s lever frame, but can be electrically operated; these are mechanical arms rather than coloured lights.
