摘要： A wind sensor, such as a sonic anemometer, may be utilized to cause a trolling motor to activate to propel a watercraft toward a virtual anchor location, route, or destination, in response to detection of an occurrence or wind. In some instances, the trolling motor may be steered to a direction opposite a wind direction when activated. The trolling motor may also be oriented to a corrective direction based on a comparison of a current location to the virtual anchor location, route, or destination. Propelling the watercraft may also include determining a propulsion correction based on wind speed, wind direction, and/or watercraft characteristics. Depending on the configuration, the wind sensor may be integrated into the housing of the trolling motor.

摘要： The invention relates to a flow measuring instrument which ascertains the water level of a watercourse, the flow rate of the watercourse at a specific location, and the wind velocity at the location of the measuring instrument, and these three measurement data are incorporated in the calculation of the average flow rate of the watercourse and/or of the calculation of the flow. By taking the wind velocity above the watercourse into consideration, calculation of the flow can be improved.

摘要： According to an embodiment, a detection system includes a detection device, an acoustic emission sensor, and a processing unit. The detection device detects a change that occurs in a structure or a change in an environment related to the structure. The acoustic emission sensor detects an acoustic emission wave produced from the structure. The processing unit performs first signal processing to process an acoustic emission signal indicating the acoustic emission wave, which is input from the acoustic emission sensor until a first period of time elapses after a detection signal is input from the detection device. The detection signal indicates that a change has occurred in the structure or the environment related to the structure.

摘要： An ultrasonic transducer is described for use in a fluid medium. The ultrasonic transducer includes at least one piezoelectric transducer element and at least one matching element for promoting an oscillation injection between the piezoelectric transducer element and the fluid medium. The ultrasonic transducer also includes a housing (112), the piezoelectric transducer element being inserted in the housing. The housing has at least one opening facing the fluid medium, the matching element being inserted at least partially into the opening.

摘要： The invention relates to a probe for aerodynamic measurement of an airflow. The probe comprises a plate rotating about an axis, a transmitter for transmitting a sound wave and a receiver responsive to the sound wave, the transmitter and the receiver forming two elements which are integrally connected to the plate and are placed at separate positions on the plate, the probe furthermore comprising means for delivering information representing a time of flight of the sound wave between the two elements and a temporal variation of the information. In the case of using the probe on board a helicopter, the rotating plate is advantageously placed at the centre of the rotor of the helicopter while being integrally connected to it. This type of probe makes it possible to carry out aerodynamic measurements even at low airspeeds of the helicopter.

摘要： The object is to facilitate determination of a flow rate of fluid discharged from a discharge opening. Intensity of a supersonic wave generated at and propagated from a discharge opening in association with discharge of the fluid from the discharge opening is determined at a determinate site distant from the discharge opening. And, a propagation distance from the discharge opening to the determination site is determined or investigated. Then, based upon a correlation existent among the intensity of the propagated supersonic wave, the propagation distance and the fluid discharge flow rate from the discharge opening, the fluid discharge rate is obtained from the determined or investigated supersonic wave intensity and the propagation distance.
