US11644555B2 Threshold generation for coded ultrasonic sensing
In an ultrasonic detection system that uses frequency-modulation coding to distinguish emitted bursts from multiple transducers, a receiver associated with a transducer uses dynamic thresholding to discriminate valid echoes from system and environmental noise in multiple envelope signals produced by multiple correlators.

US11644522B2 Triangular beam configurations for rapid beam alignment in 5G and 6G
In 5G and 6G, beam alignment remains an arduous, time-consuming process. Procedures are disclosed herein for rapid and efficient beam alignment, by configuring a phased-array antenna to emit a “triangular beam”, which is a wide beam that varies in angle from a high power at angle-1 to a low power at angle-2, with a ramp-like intensity variation in the region between the two angles. Then a second signal is emitted, with the triangular distribution reversed (higher power at angle-2). A receiver can then measure the as-received amplitudes from the two triangular beams, calculate the ratio of signal reception from the two beams, and thereby determine the alignment angle. In another version, the transmitter transmits two non-directional pulses, and the receiver detects them using a triangular sensitivity distribution versus angle. By either method, the devices can align their beams using just two triangle beam pulses, saving substantial time, resources, and background generation.

A travel control device for a vehicle, includes: a lane information acquisition unit configured to acquire lane information; a steering control unit configured to control steering of the vehicle by executing lane travel control to make the vehicle travel along the lane; and a vehicle speed control unit configured to control a vehicle speed by executing constant speed travel control in which the vehicle is made to travel at a set vehicle speed and/or adaptive cruise control in which the vehicle is made to travel at a speed equal to or lower than the set vehicle speed so as to follow a preceding vehicle. The vehicle speed control unit is configured to control the vehicle speed during a turn of the vehicle by setting a vehicle speed upper limit value, which is set to different values depending on whether the lane travel control is being executed.
US11643057B2 Vehicle traveling control apparatus
Driving support ECU transmits a communication connection request to a help net center HNC when a driver of a vehicle has been determined to be in an abnormal state where the driver loses an ability to drive the vehicle, and when the communication connection to the help net center HNC has been established, the driving support ECU transmits the help signal (the positional information of the vehicle) and decelerates the vehicle at a constant deceleration to make the vehicle stop. On the other hand, when the communication connection to the help net center HNC has not been established, the driving support ECU makes the vehicle travel at a constant speed. Accordingly, it is possible to make the vehicle stop under a situation where the help net center HNC recognizes the vehicle position inside which the driver who has been determined to be in the abnormal state is.
US11643054B2 Vehicle moving devices and methods for moving a vehicle
A vehicle moving device for moving a vehicle from a first location to a second location includes a frame having a first end and a second end. A driving wheel is coupled to the first end of the frame and configured to contact a vehicle wheel at a first wheel location. A holding arm is coupled to the second end of the frame opposite the driving wheel and configured to contact the vehicle wheel at a second wheel location. The holding arm holds the vehicle wheel in contact with the driving wheel as the driving wheel rotates the vehicle wheel.
US11643052B2 Cleaning apparatus for sensor
A sensor-cleaning apparatus includes an upper piece, a lower piece fixed to the upper piece, a plurality of inserts inserted into the upper piece, and a plurality of nozzles. The upper piece and the lower piece form a tubular segment that is elongated along an arc of a circle and encloses a chamber. Each nozzle is formed of the upper piece and one of the inserts. Each nozzle includes a deflection surface and a tunnel from the chamber to the deflection surface, and each tunnel is partially formed of the upper piece and partially formed of the respective insert.
