Abstract: A broadcast device (10) for wirelessly broadcasting information pertaining to a first aircraft (1) comprises a positioning device (11) configured to determine a position (P1) of the broadcast device (10). The position comprises a latitude, a longitude, and an altitude. A control unit (12) of the broadcast device (10) is configured to receive this position (P1) via an internal bus. Then, the control unit (12) truncates the latitude and the longitude and generates a data packet (DI) based on the truncated latitude, the truncated longitude, the altitude, and an identifier (ID1) of the broadcast device (10). Further, the data packet (D1) comprises a pair c1=(e1, m1) with an exponent (e1) being a natural number and with a mantissa (m1) being a natural number. This pair (c1) is indicative of a value (v1). The data packet (D1) is then wirelessly broadcasted by means of a radio transmitter (13) of the broadcast device (10).

Abstract: Circuitry to automatically compensate a differential output oscillator circuit for common mode disturbances that may affect the oscillator output. For any differential oscillator the common mode voltage excursion may reduce the oscillator output, which in some examples may negatively affect the circuitry receiving the oscillator output. The addition of feedback circuitry with an automatic gain control, e.g., to regulate the differential output voltage, may further reduce the gain of the oscillator in the presence of common mode voltage. In contrast, the feedback circuitry of the oscillator circuit of this disclosure may include gain control circuitry to increase an output voltage amplitude at the differential output terminals for a duration of the common mode disturbance.

Abstract: Radar frequency range signals (e.g., 1 to 100 gigahertz) are often generated by upconverting a reference frequency to a transmission frequency, and a received signal may be downconverted to analyze information encoded on the transmission via modulation. Modulation may be achieved via a fractional frequency divider in a phase-locked loop, but fractional spurs may reduce the signal-to-noise ratio. Additionally, the ramp slope may vary due to phase-locked loop momentum. Instead, a clock generator may generate clock signals for a digital front end comprising a digital signal modulator that generates modulated digital values comprising quadrature representations of a radar modulation signal, which are encoded by a radiofrequency digital-to-analog converter (RF-DAC). The RF-DAC analog signal may be upconverted to a radar frequency and transmitted. A receiver may receive, downconvert, and analyze a reflection of the radar transmission, e.g.

Abstract: Systems and techniques are described herein for detecting a state of presence of a given object in a vehicle. In aspects, techniques include processing data received over time from various devices in the vehicle to determine a set of accumulated scores. The data includes parameters indicative of a presence or absence of a detected object in the vehicle. Further, the processing may be effective to determine a set of accumulated scores. The techniques further include determining an object-related confidence value representing a likelihood that the detected object is present in the vehicle, based on the set of accumulated scores, and then comparing the object-related confidence value to a predetermined threshold. The comparison is sufficient to detect the presence of the detected object in the vehicle if the object-related confidence value exceeds the predetermined threshold.

Abstract: This document describes techniques, apparatuses, and systems for a parameter defined stepped frequency waveform for a radar system. A radar system transmits radar transmit signals including a parameter defined stepped frequency waveform with a specific change in frequency between chirps. The specified change in frequency may increase the signal to noise ratio of radar receive signals reflected off an object in the field of view. The radar receive signals may then be transformed into the frequency domain to determine a range and range rate of the object in the field of view. The range and range rate determined from the representation of the radar receive signals in the frequency domain may be output to a radar tracker to enable tracking of the object in the field of view. In doing so, accurate radar tracks may be generated that robustly track objects in the field of view of the radar system.

Abstract: This document describes techniques and systems for selecting a parking space using a probabilistic approach. An example system includes a processor that can determine whether multiple parking spaces are available in proximity to a host vehicle using sensor data. Parking-space characteristics (e.g., a width, entry turning radius, and longitudinal distance to the parking space) of each available parking space are determined using the sensor data. The processor can then choose a selected parking space among the multiple parking spaces based on the parking-space characteristics. The processor or another processor can then control the host vehicle to park in the selected parking space using an assisted-driving or autonomous-driving system. In this way, the described system can select and navigate to a parking space using a probabilistic approach. The processor can choose the parking space and parking maneuver based on programmable and customizable parking-space characteristics in some implementations.

Abstract: The techniques and systems herein enable collision indication based on yaw rate and lateral velocity thresholds. Specifically, an in-path band is determined for a predicted path of a host vehicle. Responsive to determining that a target is within the in-path band, a lateral movement for the host vehicle at a time is determined based on whether a yaw rate of the host vehicle meets a yaw rate threshold. A lateral movement for the target at the time is also determined based on whether a lateral velocity of the target meets a lateral velocity threshold. A collision indication is generated responsive to determining, based on the lateral movements, that the host vehicle and the target are likely to be within the in-path band at the time. In this way, the collision indication more accurately reflects an imminent collision, thereby increasing safety while also mitigating false-positive events.
