Abstract
Exemplary techniques for recording a context for sensed biological data are described. One technique senses biological data from a patient and records supporting data with the sensed biological data.
Claims23
An implantable medical device (IMD) comprising:
- a mechanism sensing biological data from a patient;
- a pseudo-noise generating mechanism that generates a pseudo-noise sequence, wherein the sequence is a relatively constant low-energy signal throughout the frequency spectrum except near the lowest frequencies;
- and
- a mechanism embedding supporting data on the sensed biological data in a single data file, wherein the mechanism embedding supporting data combines the supporting data with the pseudo-noise sequence to generate a pseudo-noise signal that is embedded on the sensed biological data and the supporting data is encoded as binary data having bits of the binary data divided into multiple supporting data fields.

An implantable medical device (IMD) comprising:
- means for sensing biological data from a patient, wherein the means for sensing comprises at least one electrode for positioning in electrical contact with a patient tissue and an analog-to-digital converter for converting biological data sensed by the at least one electrode into digital data in accordance with at least one parameter setting of the IMD;
- means for obtaining supporting data;
- means for generating a pseudo-noise sequence comprising a context recording module operable to combine the supporting data with the pseudo-noise sequence to generate a pseudo-noise signal, wherein the means for generating the pseudo-noise sequence generates a relatively constant low-energy signal throughout the frequency spectrum except near the lowest frequencies;
- means for embedding the supporting data upon the sensed biological data by embedding the pseudo-noise signal upon the sensed biological data as a digital watermark;
- and
- means for generating a data file containing the sensed biological data embedded with the supporting data.
3 more elements
A computer-implemented method comprising:
- sensing biological data from a patient;
- accessing supporting data relating to said sensing;
- and
- embedding the supporting data on the sensed biological data, wherein the embedding is performed on portions of the sensed biological data from which substantially no parameter values are derived and which are of less prognostic value than the other portions of the sensed biological data.
