Abstract
A method and device for decoding a sequence of signals in which information is derived, in part, from a duration of (a) one of the signals and/or (b) an inter-signal pause between two of the signals. The method and device may also be used to decode a signal to form decoded information, derived, in part, from a duration of the signal.
Claims4
A method for distinguising among a plurality of devices on a network or among a plurality of data elements, comprising the steps of:
- assigning a sequence of two or more signals to a device or data element, where each signal in the sequence has a frequency, and
- at least one signal has a specific duration;
- or
- the sequence has a time-specific pause between at least two adjacent signals;
- or
- at least one signal has a specific duration and the sequence has a time-specific pause between at least two adjacent signals;
- receiving one of the assigned sequences of signals;
- detecting the frequency and duration of the signals in the received sequence and time-specific pauses between adjacent signals in the sequence;
- and
- in response to the step of detecting, identifying the device or data element corresponding to the received sequence of signals.

A system for distinguishing among a plurality of devices on a network or among a plurality of data elements, comprising:
- means for assigning a sequence of two or more signals to a device or data element, where each signal in the sequence has a frequency, and
- at least one signal has a specific duration;
- or
- the sequence has a time-specific pause between at least two adjacent signals;
- or
- at least one signal has a specific duration and the sequence has a time-specific pause between at least two adjacent signals;
- means for receiving one of the assigned sequences of signals;
- means for detecting the frequency and duration of the signals in the received sequence and time-specific pauses between adjacent signals in the sequence;
- and
- means, responsive to the means for detecting, for identifying the device or data element corresponding to the received sequence of signals.
