Abstract: In one aspect, the present invention is directed to a system for carrying out a simultaneous translation teleconference, the system comprising: a teleconferencing room; a scheduler, for managing a schedule of a human simultaneous translator and of the teleconferencing room; and a user interface between a user and the scheduler, for ordering a teleconference between the human translator and participants in the teleconferencing room; thereby allowing carrying out a simultaneous translation teleconference between the participants and the human translator. The user interface may be an Internet menu, an audio menu, a video menu and so on. According to one embodiment of the invention, the user interface is embodied as a code dialed with a requested telephone number, thereby informing the system of the telephone company thereof to identify a request for scheduling a teleconferencing room for carrying out an STT. Preferably, the code is associated with at least one language.

Abstract: It is an aim of the preferred embodiment, to provide an improved sensor unit that is at least as reliable as two sensor units of the prior art, thereby allowing one unit per fencing unit, i.e. per stretch of fencing between adjacent support posts to provide long term reliability.
