Abstract
The disclosure is directed to a wearable device that is configured to secure itself based on signals received from a pulse sensor. According to one implementation, the pulse sensor includes a light source (e.g., a light-emitting diode) and a photo sensor. The light source, under the control of a processor, shines light having a particular wavelength (e.g., green or infrared). The photo sensor generates signals based on light that it senses. For example, when the light from the light source reflects off a person's skin, then the photo sensor will generate signals based on the reflected light that the photo sensor detects. In this manner, the wearable device can accurately determine whether it is being worn by a user (e.g., by taking a photoplethysmogram) and, when necessary, secure the wearable electronic device.
