摘要： An underwater communication interface apparatus includes a first waterproof enclosure having an interior configured to house an electronic device with a touchscreen in such a way that the touchscreen of the electronic device is adjacent to a first side of the first waterproof enclosure. The first side of the first waterproof enclosure has a non-rigid transparent membrane and the non-rigid transparent membrane is configured to allow a user to interact with the touchscreen of the electronic device. The apparatus also includes a second waterproof enclosure that houses a control module. The control module is configured to be operatively coupled to the electronic device and an external auxiliary device. The apparatus further includes a pressure balancing module coupled to the first waterproof enclosure. The pressure balancing module is configured to balance pressure within the first waterproof enclosure relative to external ambient conditions. The first and second waterproof enclosures are physically coupled together. An internal pressure of the first waterproof enclosure enables the non-rigid transparent membrane of the first waterproof enclosure to remain within a predetermined distance to the touchscreen of the electronic device. The predetermined distance is one that allows the touchscreen of the electronic device to receive inputs from the user via the non-rigid transparent membrane.

摘要： Disclosed are a signal processing method and an abnormal sound detection system. First, a neural network model is trained, including: (a) randomly selecting a plurality of sample signals from a training database to obtain a combined signal, wherein the training database includes the first sample set belonging to the first classification label and the second sample set belonging to the second classification label, and the number of selected sample signals conforms to the preset number; repeating the said step to obtain a plurality of combined signals and using the combined signals to train the neural network model. Then, a sound signal received from a sound receiving apparatus is inputted to the trained neural network model to output a probability value, and a corresponding notification signal is outputted based on the probability value.

摘要： An ultrasonic transducer for an ultrasonic flowmeter includes at least one electro-acoustic element, at least one housing, at least one acoustic window and at least one control unit. The electro-acoustic element is arranged within the housing on the acoustic window such that, during operation, an ultrasonic signal generated by the electro-acoustic element leaves the housing through the acoustic window. The electro-acoustic element has at least two electro-acoustic discs. The at least two electro-acoustic discs are arranged one above the other. At least one electro-acoustic disc can be excited separately, at least temporarily, by the control unit.
