System and method for attaching and securing a sensor
A sensor strap system according to an embodiment of the present disclosure includes: a sensor capable of detecting physical or physiological activities or conditions of a target subject; a top strap extending along a top surface of a bed, the top strap configured to secure the sensor to the top surface of the bed; and a circumferential strap extending about a circumference of the bed and coupled with the top strap.
1. A sensor strap system for attaching a sensor to a bed, comprising:
a sensor capable of detecting physical or physiological activities or conditions of a target subject;
a top strap extending along a top surface of the bed, the top strap configured to secure the sensor to the top surface of the bed; and
a circumferential strap extending about a circumference of the bed and coupled with the top strap.
2. The sensor strap system of claim 1 , wherein the circumferential strap has at least one non-elastic portion to which the top strap is coupled, and at least one elastic portion.
3. The sensor strap system of claim 1 , wherein the top strap is coupled with the circumferential strap via a connection mechanism.
4. The sensor strap system of claim 1 , wherein the top strap is capable of coupling with the circumferential strap at different positions along the circumferential strap.
5. The sensor strap system of claim 2 , wherein an end of the top strap is coupled with the circumferential strap at a fixed position along the circumferential strap to fix a position of the sensor relative to the length of the bed.
6. The sensor strap system of claim 1 , wherein the circumferential strap is adjustable.
7. The sensor strap system of claim 5 , wherein the circumferential strap further comprises a corner indicator positioned at a corner of the bed.
8. The sensor strap system of claim 7 , wherein the corner indicator is a rigid corner piece.
9. The sensor strap system of claim 8 , wherein the non-elastic portion of the circumferential strap extends from the corner indicator to the fixed position where the top strap is coupled with the circumferential strap.
10. The sensor strap system of claim 1 , wherein the bed comprises a mattress, and wherein the circumferential strap extends about a circumference of the mattress.
11. The sensor strap system of claim 1 , further comprising an electronics module coupled with sensor.
12. The sensor strap system of claim 11 , wherein the electronics module is attached to the circumferential strap.
13. The sensor strap system of claim 11 , wherein the electronics module is attached to the top strap.
14. A sensor strap system for attaching a sensor to a mattress having an outer circumference and corners, comprising:
a sensor capable of detecting physical or physiological activities or conditions of a target subject;
a top strap extending along a top surface of the mattress, the top strap configured to secure the sensor to the top surface of the mattress;
a circumferential strap extending about a circumference of the mattress, the circumferential strap having at least one non-stretchable portion with which the top strap is coupled, and at least one stretchable portion, and further comprising two corner indicators each positioned at one of the corners of the mattress; and
an electrical conductor connected to the sensor, the electrical conductor arranged along the top strap.
15. The sensor strap system of claim 14 , wherein an overall length of the electrical conductor is capable of expanding and contracting while remaining arranged along the top strap to accommodate stretching and contracting of an overall length of the top strap.
16. The sensor strap system of claim 15 , wherein the electrical conductor is an electric cable arranged in a zig-zag pattern.
17. The sensor strap system of claim 15 , wherein the electrical conductor is an electric cable with a slack loop.
18. A sensor strap system for attaching a sensor pad to a mattress having an outer circumference and four corners, comprising:
a sensor pad capable of detecting physical or physiological activities or conditions of a target subject;
a circumferential strap extending about a circumference of the mattress, the circumferential strap having at least one non-elastic portion and at least one elastic portion, the circumferential strap further comprising two corner indicators, each corner indicator positioned at one of the four corners of the mattress; and
two top straps extending along the top surface of the mattress connecting the sensor pad to the circumferential strap, wherein an end of each of the two top straps is coupled with the circumferential strap at a fixed position along the circumferential strap to fix a position of the sensor relative to the length of the bed;
wherein the at least one non-elastic portion of the circumferential strap extends along a portion of the length of the mattress from at least one of the two corner indicators to the fixed positions along the circumferential strap where the end of each of the two top straps is coupled with the circumferential strap.
19. The sensor strap system of claim 18 , further comprising:
an electronics module coupled with the sensor pad; and
an electric cable coupling the electronics module with the sensor pad, the electric cable arranged in a zig-zag pattern along one of the two top straps.
20. The sensor strap system of claim 19 , the one of the two top straps having a stretchable overall length such that the zig-zag pattern of the electric cable accommodates stretching of the stretchable overall length.
