Abstract: The methods and systems herein enable relative movement-based seatbelt use detection. Image data of an occupant of a vehicle is received over time. The image data is then input into a machine-learned model or other module that determines whether relative movement between one or more portions of the occupant and corresponding portions of a seatbelt are less than a threshold amount. If the relative movement is less than the threshold amount, an indication of seatbelt misuse (e.g., a fake seatbelt) is output to a vehicle component. By basing the indication of seatbelt misuse on relative movement between the occupant and the seatbelt, seatbelt use detection may be improved.

Abstract: Methods and systems are described that enable world geodetic system (WGS) to cartesian coordinate conversion for driving. A path of a vehicle comprising lane-group segments (LGSs) is received. The LGSs comprise respective origins in WGS coordinates, respective path points in WGS coordinates; and respective groups of constants. For a first of the LGSs, global cartesian path coordinates are calculated, based on modified Bowring techniques, for the path points of the first LGS. The coordinates are calculated using the constants of the first LGS and respective differences between the path points of the first LGS and an origin of the first LGS. The vehicle can navigate along the path using the global cartesian path coordinates calculated for the first LGS. By using modified Bowring techniques and pre-calculated constants for each LGS of the path, accuracy can be maintained over long distances and across boundaries without requiring substantial computational overhead.

Abstract: This document describes techniques and systems to vary waveforms across frames in lidar systems. The described lidar system transmits signals with different waveforms for the same pixel of consecutive frames to avoid a return signal overlapping with a noise spike or a frequency component of another return signal. The different waveforms can be formed using different frequency modulations, different amplitude modulations, or a combination thereof for the same pixel of consecutive frames. The lidar system can change the waveform of the transmit signal for the same pixel of a subsequent frame automatically or in response to determining that a signal-to-noise ratio of the return signal of an initial frame is below a threshold value. In this way, the lidar system can increase the signal-to-noise ratios in return signals. These improvements allow the lidar system to increase its accuracy in determining the characteristics of objects that reflected the return signals.

Abstract: This document describes techniques, apparatuses, and systems for a multi-layer air waveguide with layer-to-layer connections. Each pre-formed layer of the air waveguide is attached to at least one other pre-formed layer by a mechanical interface. The mechanical interface may be a stud-based interface, a snap fastener-based interface, a ball-and-socket based interface, or a pressure contact interface utilizing irregular roughed surfaces of each pre-formed layer. The mechanical interfaces of the pre-formed layers structurally hold the air waveguide together and electrically couple all of the pre-formed layers. In this manner, the cost of manufacturing the air waveguide antennas may be less expensive than previous manufacturing processes.

Abstract: Device for checking the integrity of a digital transmission for an analog output of a system. The analog output may be checked for transient errors that can be attributed to a digital transmission path embedded somewhere within the vehicle system. A test signal is introduced into a digital transmission that can be reassembled from an analog path of the analog output, and, if not, allows the test device to pinpoint that errors are appearing due to the digital path, and not because of the analog output. In this way, debugging an installation of a system becomes easier; obtaining confidence in reliability of a mixed analog and digital system becomes less of a challenge and less time consuming.

Abstract: This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.

Abstract: The techniques of this disclosure enable frequency-modulated continuous-wave radar-based detection of living objects. Instead of generating a chirp pattern with each chirp separated by an idle period, a radar generates a chirp pattern with multiple chirps separated by an idle period. From applying a Fourier transform to receiver signals for each frame, the radar determines an amplitude as a function of range for each frame. The radar computes the standard deviation between the amplitudes of two frames and then, for each additional frame, the radar incrementally updates the standard deviation to be inclusive of the amplitude contribution of the additional frame. That is, rather than recalculate the standard deviation for each new frame, the radar increments the standard deviation by a fraction of the amplitude for the new frame, which is proportionate to the total quantity of frames generated thus far.

Abstract: This document a two-part folded waveguide with horns. For example, a waveguide includes a channel with an opening in a longitudinal direction at one end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the channel. One part of the waveguide defines a surface of the channel featuring a plurality of radiation slots in the shape of a horn, which allows the two parts of the waveguide to be arranged and configured as one component. A first part of the waveguide has slots and an upper half of the walls of the channel and a second part provides a lower half of the walls of the channel and a surface of the channel opposite the slots. Using horns in combination with two parts enables ease of manufacturing a waveguide with an internal channel having a folded or sinusoidal shape.
