A method and a device for determining and displaying a flyaway distance for a rotorcraft in the event of an engine of the rotorcraft failing, and while taking account of the height of waves being overflown by the rotorcraft. The method includes a first determination for determining a flyaway distance of the rotorcraft in the event of a failure of an engine and under current flying conditions, a second determination for determining a maximum altitude of the waves being overflown by the rotorcraft and displaying the flyaway distance and the maximum altitude on a display instrument of the rotorcraft indicating the relative height of the rotorcraft or else its altitude. A safety margin is preferably added to the maximum altitude of the waves, or else to the flyaway distance of the rotorcraft.

A method of determining kinetic information may include: receiving a plurality of raw information related to a plurality of objects using a radar device provided in a vehicle; obtaining, by analyzing the plurality of raw information, a plurality of candidate kinetic information related to the vehicle; estimating, through spatial filtering, current first kinetic information related to the vehicle from the plurality of candidate kinetic information; and correcting, using a kinetic model, the estimated current first kinetic information based on current first kinetic information, wherein the current first kinetic information is predicted from previous first kinetic information related to the vehicle using a kinetic model.

An object detection apparatus includes an object detecting unit, a temporary determination unit a speed acquiring unit, and a final determination unit. The object detecting unit detects a pedestrian or a two-wheeled vehicle as an object that is present in a periphery of an own vehicle by performing image processing on a captured image capturing an advancing direction of the own vehicle. The temporary determination unit temporarily determinates a type of the object detected by the object detecting unit by analyzing the captured image. The speed acquiring unit acquires a movement speed of the object using reflected waves of a carrier wave. The final determination unit finally determines the type of the object temporarily determined by the temporary determination unit using the movement speed acquired by the speed acquiring unit.

A system for determining a stationary state of a rail vehicle on a track includes a first radar mounted at an end of the rail vehicle and a second radar mounted at another end of the rail vehicle. A speed sensor is mounted on the rail vehicle. A series of fixed reflective track features are found along the track. A processing unit, communicably connected with the speed sensor, the first radar and the second radar receives data from the first radar and the second radar corresponding to the distance to the fixed reflective track features and determines the stationary state or low-speed condition of the rail vehicle and checks the state or condition by comparing it with an output of the speed sensor.

Multiple exemplary systems for preventing jackknifing are disclosed. The systems comprise an electric motor for extending a shaft into a fifth wheel coupling when a tractor trailer is traveling at above a predetermined speed in a forward direction, physically preventing the tractor trailer from jackknifing. In order to avoid dependence on integration with a tractor, sensors on a trailer are used to determine speed without communication with the tractor or any instruments therein, via reception of one or more emitted waves. When the trailer is determined to be traveling at below the predetermined speed in a forward direction, or at any speed in a backward direction, the shaft is retracted to allow the trailer to freely rotate with respect to the tractor.

A positioning and odometry system (POS) includes one or more sensors configured to collect sensor data. The one or more sensors are operably coupled to a portable housing configured to be coupled to a vehicle body. POS has processing circuitry operably coupled to the one or more sensors. The processing circuitry is configured to determine, in response to the collected sensor data from the one or more sensors, vehicle position and odometry data.

In some examples, a system is configured to be mounted on a vehicle, the system including one or more phased-array radar devices configured to transmit first radar signals, receive first returned radar signals, transmit second radar signals, and receive second returned radar signals. In some examples, the system also includes processing circuitry configured to detect an object based on the first returned radar signals and determine an estimated altitude of the vehicle above a ground surface based on the second returned radar signals.
