Abstract: Methods, electronic devices, and storage media for driving an interaction object are provided. The methods include: obtaining an audio signal at a periphery of a display device; obtaining, based on the audio signal, first driving data for driving the interaction object to respond; monitoring, in response to outputting the first driving data, the audio signal for detecting a sound of a target object; and driving, based on a presence state of the sound of the target object in the audio signal, the interaction object to respond.

Abstract: A process for optimizing the design of a semi-open centrifugal pump impeller involves the steps of, reducing the number of long blades and adding a medium length splitter blade and a short length splitter blade having varying circumferential distances between any two optimized long blades. Each medium length and short length splitter blade have the same outlet position, profile and thickness as the optimized long blade; however, the medium length and short length splitter blades have different inlet positions relative to the optimized long blade. The long blade, medium length splitter blade and short length splitter blade are arranged in circumferential sequence along the direction of rotation of the impeller. This optimization improves various problems arising from the original semi-open centrifugal pumps, including low efficiency, significant loss at the inlet, inlet cavitation, separation of boundary layers at the blade inlets, narrow lift range of the dead point and excessive noise.

Abstract: Methods, apparatuses, devices, and computer-readable storage media for interactions between interactive objects and users are provided. In one aspect, a computer-implemented method includes: obtaining an image, acquired by a camera, of a surrounding of a display device that displays an interactive object through a transparent display screen, detecting at least one of a face or a body in the image to obtain a detection result, and driving the interactive object displayed on the transparent display screen of the display device to respond according to the detection result.

Abstract: A stereoscopic display device includes a case, a transparent display screen and one or more light sources. The case includes a chamber, one side of which is a front plate, the front plate is transparent, the transparent display screen is received inside the chamber and directly faces the front plate, the light sources are arranged inside the chamber and give off light towards the transparent display screen, and a picture displayed on the transparent display screen forms a reflection at the transparent display screen or at a bottom of the chamber.

Abstract: An obstacle touching detecting device for a swimming pool cleaner includes a main functional portion of the cleaner and a sensor obstacle touching detecting device. The main functional portion of the cleaner includes a cleaner main body, a controller module, and a power-driven actuating device. The controller module and the power-driven actuating device are connected to the cleaner main body. The sensor obstacle touching detecting device includes a trigger unit connected to the cleaner main body and a sensor detecting module electrically connected to the controller module. The controller module is electrically connected to the power-driven actuating device. The trigger unit works collaboratively with the sensor detecting module to trigger the sensor detecting module to generate a detection signal. An automatic detection is performed when the cleaner touches the wall or other obstacles, and the cleaner is controlled to change direction automatically.

Abstract: The present application relates to a bone conduction speaker and a smart wearable device as well as resonance processing method. The bone conduction speaker comprises a speaker body for generating vibration, a vibration sound transmitting layer in contact with a port of the speaker body for propagating vibration generated by the speaker body, and a vibration damping layer that wraps a region other than a portion of the speaker body that is in contact with the vibration sound transmitting layer. The smart wearable device is provided with the bone conduction speaker and is in direct contact with the user's body; the resonance processing method comprises filtering an audio signal within the preset frequency range or adjusting a gain of an audio signal within the preset frequency range.
