Test model for wearable devices
First Claim
1. A test model, comprising:
- a model layer having a test surface, wherein the model layer models at least one optical property of human skin, wherein the at least one optical property modeled by the model layer includes transmissivity of at least a particular wavelength of light transmitted into the model layer through the test surface;
an element rotatably disposed within the model layer; and
at least first and second contrast segments circumferentially disposed on the element such that rotation of the element causes different contrast segments to face the test surface of the model layer at different times, wherein the first and second contrast segments have contrasting optical properties with regard to at least the particular wavelength of light.

Abstract
A test model for simulating one or more physiological parameters is provided. In one example, the test model includes a model layer having a test surface, a shaft rotatably disposed within the model layer and at least first and second contrast segments circumferentially disposed on the shaft. The model layer models at least one optical property of human skin, such as transmissivity of at least a particular wavelength of light transmitted into the model layer. The first and second contrast segments have contrasting optical properties with regard to at least the particular wavelength of light, such as reflectance. Rotation of the shaft causes different contrast segments to face the test surface of the model layer at different times.

13. A method, comprising:
-
mounting a wearable device to a test model, wherein the wearable device has at least one light source and at least one detector, wherein the test model comprises; a model layer, wherein the model layer models at least one optical property of human skin, wherein the at least one optical property modeled by the model layer includes transmissivity of at least a particular wavelength of light; an element rotatably disposed within the model layer; and at least first and second contrast segments circumferentially disposed on the element, wherein the first and second contrast segments have contrasting optical properties with regard to at least the particular wavelength of light; directing light from the light source on the wearable device into the test model while the element is rotating, wherein the light from the light source includes light at the particular wavelength; and receiving, by the detector on the wearable device, light reflected from the first and second contrast segments as the element is rotating. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
