Assignee: WAYMO LLC
Field: Measurement (Instruments)
Classification: CPC G  B | IPC B  G

Claim 0:
1. A sensor assembly, comprising:
a base layer that is configured to pass signals of one or more wavelengths therethrough, the base layer having a first surface and a second surface opposite the first surface;
a sensor device configured to perform at least one of emit or receive signals of the one or more wavelengths through the base layer, the sensor device being disposed along the first surface of the base layer;
a waveguide layer having a first surface and a second surface opposite the first surface, the first surface of the waveguide layer being adjacent to the second surface of the base layer, the waveguide layer having a waveguide pattern extending between a first side and a second side of the waveguide layer;
an emitter device operatively coupled to the first side of the waveguide layer, the emitter device being configured to emit a signal of a selected wavelength having a first waveform for propagation along the waveguide pattern; and
a detector device operatively coupled to the second side of the waveguide layer, the detector device being configured to receive the signal having a second waveform, the second waveform being a modified version of the first waveform when an object is disposed along the second surface of the waveguide layer.
