A device, a substrate including a connection port. The substrate includes traces to enable a circuit of the substrate. The circuit is connected to the connection port. A light sensor mechanically and electrically attached respectfully to a first planar surface of the substrate and the circuit. A light source is mechanically and electrically attached respectively to the first planar surface and the circuit. The light source is located lateral to the light sensor at a first distance. A light signal of the light source emanates from the light source at an angle perpendicular to the first planar surface and a reflector mechanically attached to the first planar surface and located between the light sensor and the light source. The light signal is substantially reflected by the reflector away from the light sensor.
Abstract:
A method for a wearable device to determine a biological parameter of a tissue of a person. To apply an emitting of a first and a second wavelength of light towards the tissue. To collect and sense a first and a second set of frequency bands from the signals received back from the first and the second wavelengths respectively. The first set of frequency bands represents a first signal which corresponds to a combination of the biological parameter and an extraneous noise. The second set of frequency bands represents a second signal mainly comprising the extraneous noise. To subtract the first set of frequency bands from the second set of frequency bands in the frequency domain to obtain a third set of frequency bands. The third set of frequency bands represents a third signal corresponding to the biological parameter.
