Abstract:
An apparatus for transmitting a signal to a remote receiver, said apparatus comprising:a signal transmitting unit including: a) a first input for receiving a signal to be transmitted, said signal transmitting unit being operative to transmit said signal repetitively to create a succession of signal transmission events, each signal transmission event being spaced in time from a previous signal transmission event by a certain time interval characterized by a duration; b) a second input for receiving a data element to control a duration of the time interval, said signal transmitting unit being responsive to the data element to set the time interval between two successive signal transmission events at a duration conveyed by the data element; a time interval duration control module for successively generating different data elements and supplying the different data elements to said second input for varying said time interval to alter over time a rate or occurrence of the transmission events.
