    Abstract: Described herein are systems, methods, and other techniques for controlling a velocity of an implement-equipped machine. An actual position of the implement-equipped machine is estimated based on sensor data captured using the machine's sensors. A cross track error between a target position and the actual position is calculated. An actual cross track error metric is calculated based on the cross track error. The actual cross track error metric is compared to a target cross track error metric to determine a velocity adjustment, where the velocity adjustment is determined so as to reduce a difference between the actual cross track error metric and the target cross track error metric. The velocity of the implement-equipped machine is adjusted by the velocity adjustment.

    Abstract: A first user equipment (UE) may receive a first set of beacon signals from a set of global navigation satellite system (GNSS) devices. The first UE may restrict growth of a position uncertainty (PUNC) value associated with the first UE based on a maximum vehicle speed and based on a lack of a reception of a beacon signal from the set of GNSS devices within a threshold period of time. The first UE may restrict growth of the PUNC value further based on a relative velocity profile associated with the first UE. The first UE may receive a message including a second relative velocity profile from a second UE. The first UE may calculate the relative velocity profile based on the second relative velocity profile.

    Abstract: The visibility of the external scene from the inside of the transmissive transparent screen when the video image is not displayed and the visibility of the video image from the outside when the video image is displayed are satisfied.
    In a video image display system comprising a projection device 100 and a transmissive transparent screen 1 having a first surface and a second surface on the opposite side of the first surface, having a visible light transmittance of at least 5[%], and displaying video images projected from the projection device 100 installed on the first surface side, as video images visible to an observer on the second surface side, the following formula 1 is satisfied:

    −1.5≤ln(((B/A)/I)×G)≤3.9  Formula 1



    in the formula 1, A is the projection area [m2] of the projection device 100, B is the luminous flux [lm] projected onto A by the projection device 100, I is the ambient illuminance [lx] at the side of the second surface, and G is the screen gain of the transparent screen 1.

    Abstract: A traffic radar system comprises a first radar transceiver, a second radar transceiver, a speed determining element, and a processing element. The first radar transceiver transmits and receives radar beams and generates a first electronic signal corresponding to the received radar beam. The second radar transceiver transmits and receives radar beams and generates a second electronic signal corresponding to the received radar beam. The speed determining element determines and outputs a speed of the patrol vehicle. The processing element is configured to receive a plurality of digital data samples derived from the first or second electronic signals, receive the speed of the patrol vehicle, process the digital data samples to determine a relative speed of at least one target vehicle in the front zone or the rear zone, and convert the relative speed of the target vehicle to an absolute speed using the speed of the patrol vehicle.
