Abstract

A sensory-and-logic system comprises an illumination source configured to emit a blood-sensing light, a window through which the blood-sensing light passes en route to human tissue, an illumination receiver configured to measure the blood-sensing light reflected back through the window from the human tissue, a frame surrounding the window and elevating away from the window, and a pillow surrounding the frame and recessing from the frame and the window.

First claim

The invention claimed is:

1. A sensory-and-logic system, comprising:
an optical pulse-rate sensor comprising:
an illumination source configured to emit a blood-sensing light;
a first window portion of a window through which the blood-sensing light passes; and
an illumination receiver configured to measure the blood-sensing light reflected back through a second window portion of the window, wherein the first window portion, the second window portion, and all area between the first window portion and the second window portion are substantially level;

a wrist band assembly supporting the optical pulse-rate sensor and configured to encircle a wrist of a wearer;
a frame surrounding the window of the optical pulse-rate sensor and elevating away from the window toward a human tissue of the wrist of the wearer when the wrist band assembly encircles the wrist of the wearer, the frame having an inner frame portion level with the window and an outer frame portion elevated away from the inner frame portion toward the human tissue; and
a pillow surrounding the frame, the pillow including a first region surrounding the frame and level with the inner frame portion, and a second region sloping downward to the wrist band assembly.

2. The sensory-and-logic system of claim 1 , wherein the window comprises a dichroic filter.

3. The sensory-and-logic system of claim 1 , wherein the window comprises a light guide.

4. The sensory-and-logic system of claim 1 , wherein the frame comprises a ring-shaped, electrically-conductive skin sensor sized and shaped to form an electrical connection with human skin.

5. The sensory-and-logic system of claim 1 , wherein the pillow comprises a spring positioned under the illumination source, illumination receiver, window, and frame.

6. The sensory-and-logic system of claim 1 , wherein the wrist band assembly further comprises a latching mechanism positioned under the optical pulse-rate sensor, frame, and pillow, and wherein the latching mechanism urges the pillow, frame, and optical pulse-rate sensor upward such that only the frame is in contact with the wrist of the wearer when the latching mechanism is latched.

7. A sensory-and-logic system, comprising:
an optical pulse-rate sensor comprising an illumination source configured to emit a blood-sensing light, a first window portion of a window through which the blood-sensing light passes, and an illumination receiver configured to measure the blood-sensing light reflected back through a second window portion of the window, wherein the first window portion, the second window portion, and all area between the first window portion and the second window portion are substantially level;
a wrist band assembly supporting the optical pulse-rate sensor and configured to encircle a wrist of a wearer;
a frame surrounding the window of the optical pulse-rate sensor, the frame having an inner frame portion level with the window and a rim elevated out from the inner frame portion toward the wrist and away from the wrist band assembly; and
a pillow surrounding the frame, the pillow including a first region surrounding the frame and a second region sloping to the wrist band assembly.

8. The sensory-and-logic system of claim 7 , wherein the rim of the frame is elevated above the first region of the pillow.

9. A sensory-and-logic system, comprising:
an optical pulse-rate sensor comprising an illumination source configured to emit a blood-sensing light, a first window portion of a window through which the blood-sensing light passes, and an illumination receiver configured to measure the blood-sensing light reflected back through a second window portion of the window, wherein the first window portion, the second window portion, and all area between the first window portion and the second window portion are substantially level;
a wrist band assembly supporting the optical pulse-rate sensor and configured to encircle a wrist of a wearer;
a frame surrounding the window of the optical pulse-rate sensor, the frame having a rim positioned at a first vertical height relative to the wrist band assembly, the window positioned at a second vertical height relative to the wrist band assembly, the first vertical height greater than the second vertical height, and when the wrist band assembly is worn by the wearer, the rim is positioned closer to the wrist than the window; and
a pillow surrounding the frame, the pillow including a first region surrounding the frame, and a second region sloping to the wrist band assembly.

10. The sensory-and-logic system of claim 9 , wherein the rim of the frame is elevated above the first region of the pillow.
