Analysis and annotation of printed time-varying signals
First Claim
1. A substrate for carrying a printed time-varying signal, wherein the substrate carries a background pattern, in which local portions of the background pattern uniquely identify a location of the background pattern over the substrate, thereby enabling the position of annotations on the substrate which relate to portions of the signal to be determined.

Abstract
A system for analysing and annotating time-varying signals comprises a substrate for carrying the time-varying signal in printed form, a printer for printing the time-varying signal over the substrate and a reading and writing device for reading a local background pattern of the substrate and writing on the substrate, the reading and writing device enabling the position of annotations on the substrate to be determined. Local portions of the background pattern on the substrate uniquely identify a location of the background pattern over the substrate. This enables the position of annotations on the substrate which relate to portions of the signal to be determined. This enables annotations written on the printed plot to be stored digitally. The locations of the markings which define the annotations enable not only the annotations themselves to be recorded, but also the parts of the signal to which they relate.

6. A system for analysing and annotating time-varying signals, comprising:
-
a substrate for carrying the time-varying signal in printed form, wherein the substrate further carries a background pattern, in which local portions of the background pattern uniquely identify a location of the background pattern over the substrate;
a printer for printing the time-varying signal over the substrate; and
a reading and writing device for reading a local background pattern and writing on the substrate, the reading and writing device enabling the position of annotations on the substrate to be determined. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

26. A computer program for collating data relating to the analysis of a time-varying signal, the computer program adapted to:
-
receive, from a reading and writing device, local background pattern information from a substrate which carries a printed version of the time-varying signal;
determine the position of annotations on the substrate from the local background pattern information received;
determine a timing window corresponding to the portions of the time-varying signal adjacent to the annotations; and
store data relating to the timing window. - View Dependent Claims (27, 28)
