Abstract

A wrist-worn pressure sensing device includes a pressure sensor. The wrist-worn pressure sensing device also includes a first strap that sets the position of the pressure sensor on a wearer's wrist and a second strap that engages with the first strap to adjust the overall length of the strap without moving the set position of the pressure sensor on the wearer's wrist.

First claim

The invention claimed is:

1. A wrist-worn pressure sensing device, comprising:
a primary device;
a pressure sensor;
a first strap foldable to fix a position of the pressure sensor along the length of the first strap relative to the primary device, the first strap comprising:
a first end connected to the primary device;
a second end connected to the pressure sensor and configured to fold back towards the first end, wherein a relative position of a fold along the length of the first strap dictates the position of the pressure sensor along the length of the first strap relative to the primary device; and
primary fastening componentry; and

a second strap comprising:
a first end connected to the primary device; and
secondary fastening componentry usable to adjust a circumference of the wrist-worn pressure sensing device without moving the fixed position of the pressure sensor along the length of the first strap relative to the primary device by adjustably engaging the secondary fastening componentry with the primary fastening componentry.

2. The wrist-worn pressure sensing device of claim 1 , wherein the pressure sensor is communicatively coupled to a compute machine located within the primary device via the first strap.

3. The wrist-worn pressure sensing device of claim 1 , wherein the second end of the first strap folds back towards the first end of the first strap to position the pressure sensor at a fixed distance along the length of the first strap from the primary device.

4. The wrist-worn pressure sensing device of claim 1 , wherein the circumference of the wrist-worn pressure sensing device is inversely proportionate to an amount of overlap between the first strap and the second strap when the primary fastening componentry is engaged with the secondary fastening componentry.

5. The wrist-worn pressure sensing device of claim 1 , wherein the circumference of the wrist-worn pressure sensing device is inversely proportionate to an amount of self-overlap along the second strap when the primary fastening componentry is engaged with the secondary fastening componentry.
