Abstract

A limb movement monitoring system, comprising a motion sensor, a garment comprising spatially addressable photonic textiles and spatially resolving pressure-sensitive textiles and furthermore a muscular activity sensor, a processing unit processing the data from the sensors and issuing illumination commands to the spatially addressable photonic textiles and a database. There is furthermore a process for monitoring limb movement by the system.

Claims (25)

1. Limb movement monitoring system, comprising:

a motion sensor ( 1 ),

a garment comprising spatially addressable photonic textiles ( 2 ) and spatially resolving pressure-sensitive textiles ( 3 ),

a processing unit ( 5 ) which receives data from the motion sensor ( 1 ) and from the spatially resolving pressure-sensitive textiles ( 3 ) and which issues illumination commands to the spatially addressable photonic textiles ( 2 ),

a database ( 6 ) in communication with the processing unit ( 5 ), wherein

the database ( 6 ) stores data from the motion sensor ( 1 ) resolved into individual spatial descriptors and time,

the database ( 6 ) stores data from the pressure-sensitive textiles ( 3 ) resolved into at least the categories of x and y coordinates and pressure,

the database ( 6 ) furthermore comprises comparison motion data resolved into individual spatial descriptors and time,

the processing unit ( 5 ) compares the motion data from the motion sensor to the comparison motion data in the database ( 6 ), and

the processing unit ( 5 ) issues illumination commands to the spatially addressable photonic textiles ( 2 ) based upon the deviation of the motion data from the comparison motion data and the deviation of the pressure data from a preset threshold.

2. System according to claim 1 , further comprising a muscular activity sensor ( 4 ), wherein the processing unit ( 5 ) also receives data from the muscular activity sensor ( 4 ), the database ( 6 ) also stores data from the muscular activity sensor ( 4 ) and the processing unit ( 5 ) also issues illumination commands to the spatially addressable photonic textiles ( 2 ), based upon the deviation of the muscular activity data from a preset threshold.

3. System according to claim 1 , further comprising a user interface ( 7 ) for accessing data from the database.

4. System according to claim 1 , further comprising an external feedback system ( 8 ) communicating motion and/or pressure data.

5. System according to claim 1 , wherein the spatially resolving pressure-sensitive textiles ( 3 ) comprise piezoresistive fabrics.

6. System according to claim 1 , wherein the signals from the at least one motion sensor ( 1 ), from the pressure-sensitive textiles ( 3 ) and/or the commands to the spatially addressable photonic textiles ( 2 ) are transmitted wirelessly.

7. System according to claim 1 , further comprising a glove comprising spatially resolving pressure-sensitive textiles, wherein the glove transmits pressure data to the processing unit ( 5 ).

8. System according to claim 1 , further comprising sensors selected from the group comprising skin perspiration sensors, pulse sensors, blood pressure sensors and/or blood oxygen level sensors, wherein the sensors further provide input to the processing unit ( 5 ).

9. Process for monitoring limb movement by a system according to claim 1 , comprising the steps of:

a) calibrating the at least one motion sensor ( 1 ) by bringing the at least one motion sensor ( 1 ) into a predetermined position and registering the output signal from the at least one motion sensor ( 1 ) in this position

b) gathering motion sensor and pressure sensor output signals

c) assigning the motion sensor output signals to a position and a movement of the respective at least one motion sensor

d) storing the position, movement and pressure signals in a database ( 6 )

e) comparing the position, movement and pressure signals which have been stored within a predetermined timeframe to predetermined position and movement data in the database ( 6 )

f) deciding whether predefined boundary conditions with respect to position, movement and/or pressure are exceeded and communicating this.

10. Process according to claim 9 , further comprising a feedback system ( 8 ) which additionally communicates exercises for the limbs to be moved.
