Abstract: A self-moving robot includes a chassis, a laser radar and a front wheel assembly. The laser radar is fixedly connected to one side of the chassis. The front wheel assembly is rotatably supported on another side of the chassis that faces away from the laser radar. An orthographic projection of the front wheel assembly on the chassis at least partially overlaps with an orthographic projection of the laser radar on the chassis.

Abstract: The present disclosure provides systems and methods for processing a signal. The system for processing a signal may include at least one microphone and at least one vibration sensor. The at least one microphone may be configured to collect a sound signal, and the sound signal may include at least one of user voice and environmental noise. The at least one vibration sensor may be configured to collect a vibration signal, and the vibration signal may include at least one of the user voice and the environmental noise. The system for processing a signal may also comprise a processor. The processor may be configured to determine a relationship between a noise component in the sound signal and a noise component in the vibration signal, and obtain a target vibration signal by performing, based at least on the relationship, noise reduction processing on the vibration signal.

Abstract: Disclosed are a transition metal chalcogenide thin-layer material, a preparation method and an application thereof. The preparation method comprises: uniformly spreading a transition metal source between two substrates to prepare a sandwich structure; performing a heat treatment on the sandwich structure to fuse and bond the two substrates together, and performing a chemical vapor deposition reaction on a chalcogen element source and the fused and bonded sandwich structure under the protection of a protective gas, wherein the transition metal source is heated to dissolve and diffuse at a reaction temperature, separated out from surfaces of the substrates, and reacts with the chalcogen element source. The prepared thin-layer material is uniformly distributed in a centimeter-level substrate.

Abstract: Embodiments of this application provide a sensor calibration method, apparatus, and device, a data measurement method, apparatus, and device, and a storage medium, where the sensor calibration method includes: acquiring a gravity of a sensor itself and a static force measured in a case that the sensor is in a static state and has no external acting force; performing equivalent calibration processing on the gravity and the static force to obtain a calibrated static force; acquiring a dynamic force measured in a case that the sensor is in a motion state and has no external acting force; performing zero drift processing on the dynamic force according to the calibrated static force to obtain a calibrated dynamic force; and using the calibrated dynamic force as a calibration parameter for performing calibration in a case that the sensor measures an external acting force, to obtain a calibrated sensor with the calibration parameter.

The method includes: generating regional word vectors of at least two dimensions of a target word vector inputted at a first moment; combining the regional word vectors to obtain combined regional word vectors of at least two dimensions; performing aggregation transformation processing on the combined regional word vectors based on a feedforward neural network, to obtain an aggregated word vector corresponding to the target word vector; and generating a target hidden state corresponding to the target word vector based on the aggregated word vector.

Abstract: A speaker device is provided. The speaker device may include a circuit housing, an ear hook, a rear hook, and a speaker assembly. The circuit housing may be configured to accommodate a control circuit or a battery. The ear hook may be connected to one end of the circuit housing and at least a part of the ear hook being covered by a first housing sheath. The rear hook may be connected to the other end of the circuit housing and at least a part of the rear hook being covered by a second housing sheath. The first housing sheath and the second housing sheath may cover at least a part of a periphery of the circuit housing from two ends of the circuit housing, respectively. The speaker assembly may include an earphone core and a core housing for accommodating the earphone core.

Abstract: A medical image processing method includes: determining a target mask of a target object in a medical image and a reference mask of a reference object in the medical image, the target mask indicating a position and a boundary of the target object, and the reference mask indicating a position and a boundary of the reference object; determining a feature size of the target object based on the target mask; determining a feature size of the reference object based on the reference mask; and determining a target size of the target object based on the feature size of the reference object, a preset mapping relationship between the feature size of the reference object and a reference size, and the feature size of the target object.

Abstract: Provided are an information processing method and apparatus, an electronic device, and a storage medium. The method includes: acquiring an information processing application transmitted by a first client, and executing a predetermined command in accordance with a timer-based task mechanism to transmit a first prompt message for reviewing the information processing application to a second client; identifying, in response to an operation instruction on the second client, the information processing application as a target information processing application; acquiring an information processing request for the target information processing application transmitted by the first client in accordance with an asynchronous mechanism, and processing the information processing request; and feeding, in response to a polling initiated by the first client, a processing result of the information processing request back to the first client when the processing the information processing request is completed.

Abstract: The present disclosure provides an inflatable costume. The inflatable costume includes a main body and an elastic inner sleeve. The main body includes a head part and a body part. The head part is provided with a first opening. The elastic inner sleeve is connected to the head part, and is configured to adapt to heads with different sizes. Through the above structure, when a user puts on the inflatable costume, the face of the user can be exposed due to the arrangement of the first opening. Furthermore, as the elastic inner sleeve has elasticity, the elastic inner sleeve can be adjusted according to the size of the head of the user, which avoids the tension that may be caused by a traditional fixed design, so that the inflatable costume is more universal and practical, and the user experience is greatly improved.
