Abstract: Apparatus and associated methods relate to pairing a receiver with an emitter based on a presence of an amplitude of a spectral profile at at least one predetermined frequency. In an illustrative example, a receiver may receive, from the emitter, an emitted optical signal modulated by the at least one predetermined frequency. A receiver may, for example, generate a digital signal corresponding to the optical signal received. A controller may, for example, generate the spectral profile from the digital signal. The controller may, for example, apply a predetermined threshold to the spectral profile. The controller may, for example, generate an output signal based on the presence of the amplitude of the spectral profile above the first predetermined threshold at the at least one predetermined frequency. Various embodiments may advantageously discriminate a corresponding emitter to establish an optical source-to-detector-link, for example, in the presence of other emitters and/or optically noisy environments.

Abstract: Apparatus and associated methods relate to a volumetric measurement system using three dimensional (3D) ToF cameras. In an illustrative example, a VMS may include at least one 3D distance sensor unit for monitoring a volume of objects in a region of interest (ROI). The VMS may, for example, include a set of user-defined parameters including the ROI, and temporal distribution of measurement attributes associated with the ROI. In some implementations, the VMS may be activated to automatically generate a set of error compensated volumetrics. For example, the VMS may apply a 3D profile, generated based on signals received from the 3D distance sensor, to an error compensation model. Based on measurement attributes generated from applying the error compensation model, the VMS may, for example, generate a set of error compensated volumetrics. Various embodiments may advantageously compensate for errors including occlusion of objects from the 3D distance sensor.

Abstract: Apparatus and associated methods relate to enabling a radar system to use different sensing mechanisms to estimate a distance from a target based on different detection zones (e.g., far-field and near-field). In an illustrative example, a curve fitting method may be applied for near-field sensing, and a Fourier transform may be used for far-field sensing. A predetermined set of rules may be applied to select when to use the near-field sensing mechanism and when to use the far-field mechanism. The frequency of a target signal within a beat signal that has less than two sinusoidal cycles may be estimated with improved accuracy. Accordingly, the distance of a target that is within a predetermined distance range (e.g., two meters range for 24 GHz ISM band limitation) may be reliably estimated.
