A system for detecting objects using ultrasonic waves and methods for making and using the same are provided. The object detection system uniquely encodes each of a plurality of ultrasonic waves and transmit each of the uniquely-encoded ultrasonic waves in a respective direction. The object detection system then receives any of the emitted uniquely-encoded ultrasonic waves that are reflected from an object. By decoding the reflected ultrasonic waves, the object detection system distinguishes among the uniquely-encoded ultrasonic waves and detect the existence and location of the object.

An obstacle warning apparatus in a vehicle specifies a position of an obstacle relative to the vehicle based on a detection result by an obstacle sensor. A warning determination section determines whether a warning about the obstacle needs to be executed, based on the specified position of the obstacle. The warning determination section determines that the warning about the obstacle does not need to be executed when an overlap determination section determines that a vehicle range overlaps with a range where the obstacle exists.

A sensor assembly for use in association with non-integrated, ground-based collision avoidance systems for aircraft, including (a) a sensor; and (b) a frame sub-assembly, wherein the sensor is releasably securable to the frame sub-assembly.

The invention relates to a method for detecting a screening of a sensor device (4) of a motor vehicle (1) by an object (8), in which at least one echo signal, captured by the sensor device (4), that characterizes a spacing between the sensor device (4) and the object (8) is received (S1) by means of a computing device (3), a capture region (E) for the sensor device (4) is determined, and on the basis of the at least one received echo signal it is checked whether the capture region (E) of the sensor device (4) is being screened by the object (8), at least in some regions, wherein the at least one echo signal is assigned by means of the computing device (3) to a discrete spacing value (B1, B2, B3) from a plurality of discrete spacing values (B1, B2, B3), for each of the discrete spacing values (B1, B2, B3) a power value (P) is determined (S2) on the basis of the echo signal, and on the basis of the power values (P) a decision is made by means of a classifier as to whether at least a predetermined proportion of the capture region (E) of the sensor device (4) is being screened (S6) by the object (8).

A trailer angle detection system for a vehicle includes a camera disposed at a rear portion of the vehicle and viewing rearward of the vehicle. A plurality of ultrasonic sensors is disposed at the rear portion of the vehicle and sense rearward of the vehicle. A control has at least one processor operable to process image data captured by the camera. Responsive to processing of image data captured by the camera, the control detects a trailer rearward of the vehicle and in the field of view of the camera. The at least one processor is operable to process sensor data captured by the ultrasonic sensors to determine a distance to portions of the trailer rearward of the vehicle. Responsive to processing of captured image data and processing of captured sensor data, the trailer angle detection system is operable to determine an angle of the trailer relative to the vehicle.

The ultrasonic sensor includes a wave transmitting and receiving device and a cover. The wave transmitting and receiving device has a front surface including a wave transmitting and receiving surface and is configured to transmit and receive an ultrasonic wave through the wave transmitting and receiving surface. The cover covers the wave transmitting and receiving device so as to expose the wave transmitting and receiving surface. The cover is constituted by multiple portions, and the multiple portions are individually made of multiple materials different from each other.

Embodiments described herein may relate to an unmanned aerial vehicle (UAV) navigating to a target in order to provide medical support. An illustrative method involves a UAV (a) determining an approximate target location associated with a target, (b) using a first navigation process to navigate the UAV to the approximate target location, where the first navigation process generates flight-control signals based on the approximate target location, (c) making a determination that the UAV is located at the approximate target location, and (d) in response to the determination that the UAV is located at the approximate target location, using a second navigation process to navigate the UAV to the target, wherein the second navigation process generates flight-control signals based on real-time localization of the target.
