Abstract:
Method (600) and control unit (310), for avoiding a potential collision between the vehicle (100) and a Vulnerable Road User, VRU (200). The method (600) comprises: predicting (601) a future path (t1, t2, t3) of the vehicle (100); detecting (602) the VRU (200) and the position of the VRU (200); determining (603) velocity of the detected (602) VRU (200); predicting (604) a future position (210) of the detected (602) VRU (200), based on the VRU position upon detection (602) and the determined (603) VRU velocity; and performing (607) an action for avoiding a collision, when the predicted (604) future position (210) of the VRU (200) is overlapping (220) the predicted (601) future path (t1, t2, t3) of the vehicle (100).
Abstract:
Techniques are disclosed for systems and methods to provide orientation and/or position data from an orientation and/or position sensor (OPS) while it is rotating. A system includes a logic device configured to communicate with an OPS that is rotationally coupled to a mobile structure. The logic device is configured to receive orientation and/or position data from the OPS while the OPS is rotating relative to the mobile structure and determine rotationally corrected orientation and/or position data referenced to the mobile structure, a rotationally actuated sensor assembly mounted to the mobile structure, and/or an absolute coordinate frame.
Abstract:
Techniques are disclosed for systems and methods to provide augmented reality sonar imagery for mobile structures. An augmented reality sonar imagery system includes a portable imaging device, a sonar transducer assembly, and a logic device in communication with the sonar transducer assembly and the portable imaging device. The sonar transducer assembly is adapted to be mounted to a mobile structure and placed in a body of water, and the portable imaging device includes a display and an imager position and/or orientation sensor. The logic device is configured to determine a waterline of the body of water relative to a field of view of the display and render sonar data in a portion of the field of view that extends below the waterline. Subsequent user input and/or the sonar data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems.

Abstract:
Techniques are disclosed for systems and methods to provide transmission signal shaping for transmission signal-based sensor systems, such as radar and/or sonar sensor systems. A low noise signal shaping transmitter includes a digital to analog converter configured to convert a digital shaping control signal to an analog shaping control signal, a signal shaping circuit configured to convert the analog shaping control signal into a shaped voltage, and a power amplifier configured to provide a shaped transmission signal based on the shaped voltage and a digital transmission control signal. Each element of the transmitter may be formed from relatively slow switching analog and/or digital circuitry components. Resulting shaped transmission signals may be used to excite radar antennas, sonar transducers, sound cells, and/or other elements of sensor systems.
Abstract:
The invention relates to a method for identifying a dangerous situation, wherein the dangerous situation exists for a vehicle (104) and/or emanates from the vehicle (104), wherein a plurality of measurement values are detected by means of different sensors of the vehicle (104), vehicle-to-X messages are detected by means of vehicle-to-X communication means of the vehicle (104), and data contents of the vehicle-to-X messages and the measurement values describe a situation of the surroundings of the vehicle (104) and/or a vehicle state. The method is characterized in that a defined dangerous situation is identified when the measurement values and/or the data contents of the dangerous situation meet associated criteria. The invention further relates to a corresponding system and a use of the system.

Abstract:
The invention relates to an ultrasonic-based measuring sensor (10a - 10e), like distance sensor or dead angle sensor, having a membrane element (16) that can be electrically exited to vibrations by way of an actuating unit (20). According to the invention, the actuating unit (20) and/or the membrane element (16) are configured to carry out a heating mode that is modified with respect to the measuring mode, wherein the membrane element (16) heats up to a temperature (T), which is above an ice-formation temperature, and the heating mode comprises an actuation of the membrane element (16) that is extended or/and a at higher frequency relative to the measuring mode.
Abstract:
A sector-scanning sonar imaging system with at least one sonar imaging element housed within a transducer housing coupled to a self-reciprocating mechanism, and a drive mechanism housed within a waterproof housing. The oscillating motion of the transducer housing produces a highly-detailed, photo like sector scan sonar image of the bottom and other objects surrounding the boat on which it is mounted. The drive mechanism housing may be rigidly attached to either a boat hull or to a trolling motor. The sonar imaging element housing may be removably attached to the drive mechanism, and shielded by an acoustically transparent shroud to protect the elements from damage. The sector-scanning sonar imaging system connects to a control head with display either directly, or through some other communications protocol, such as a wireless protocol.
