Abstract: A lipid delivery system, a virus-like structure (VLS) vaccine constructed therefrom, and a lipid particle capable of encapsulating an mRNA molecule encoding a SARS-CoV-2-specific antigen are provided. After the lipid particle encapsulates an mRNA molecule encoding a SARS-CoV-2 antigen, a SARS-CoV-2 S1 antigen protein can be embedded on a surface of an envelope structure of the lipid under specific buffer conditions to produce a VLS vaccine with an antigen-encoding mRNA molecule encapsulated inside and an outer membrane presenting a required viral antigen protein. The vaccine has a superior specific antibody-inducing ability to a SARS-CoV-2 mRNA vaccine and a polypeptide vaccine, can maintain a long-lasting high antibody level, and can also exhibit excellent immune binding abilities for the emerging different variants.

Abstract: An autonomous mobile device (AMD) may perform various tasks during operation. Some tasks, such as delivering a message to a particular user, may involve the AMD identifying the particular user. The AMD includes a camera to acquire an image, and image-based authentication techniques are used to determine a user's identity. A user may move within in a physical space, and the space may contain various obstructions which may occlude images. The AMD may move within the space to obtain a vantage point from which an image of the face of the user is obtained which is suitable for image-based authentication. In some situations, the AMD may present an attention signal, such as playing a sound from a speaker or flashing a light, to encourage the user to look at the AMD, providing an image for use in image-based authentication.

Abstract: An autonomous mobile device (AMD) or other device may perform various tasks during operation. The AMD includes a camera to acquire an image. Some tasks, such as presenting information on a display screen or a video call, may involve the AMD determining whether a user is engaged with the AMD. The AMD may move a component, such as the camera or the display screen, to provide a best experience for an engaged user. Images from the camera are processed to determine attributes of the user, such as yaw of the face of the user, pitch of the face of the user, distance from the camera, and so forth. Based on the values of these attributes, a user engagement score is determined. The score may be used to select a particular user from many users in the image, or to otherwise facilitate operation of the AMD.

Abstract: A system includes one or more processors and a memory that stores a generative adversarial network (GAN). The one or more processors are configured to receive a low resolution point cloud comprising a set of three-dimensional (3D) data points that represents an object. A generator of the GAN is configured to generate a first set of generated data points based at least in part on one or more characteristics of the data points in the low resolution point cloud, and to interpolate the generated data points into the low resolution point cloud to produce a super-resolved point cloud that represents the object and has a greater resolution than the low resolution point cloud. The one or more processors are further configured to analyze the super-resolved point cloud for detecting one or more of an identity of the object or damage to the object.

Abstract: A system and method for verifying detection of partially occluded objects (e.g., pedestrians) in the vicinity of a vehicle. An image input device captures an image and/or video of surroundings. An object detector detects partially occluded pedestrians and other objects in received image information. The detection of a partially occluded pedestrian is verified when a detection window of the partially occluded pedestrian overlaps with a detection window of an occluding object, and the occluding object window is closer to the image input device than the partially occluded object window. Optionally, a range-finding sensor, such as a LIDAR device, determines a range to objects located in the direction of the partially occluded object. The detection of the partially occluded object is verified when the range of one of the other objects located in the direction of the partially occluded object is less than that of the partially occluded object.

Abstract: A snow and road sweeping vehicle with a brush body turning apparatus includes a vehicle body, a brush bracket, a brush body arranged on the brush bracket, and a drive mechanism. The snow and road sweeping vehicle further includes a rotating shaft assembly, at least two limiting holes, and a limiting assembly. The limiting assembly is selectively inserted into one of the limiting holes to position the brush bracket. The present invention can change the orientations of the brush bracket and the brush body to facilitate the operation and improve the sweeping efficiency.

Abstract: A sweeping car with one-brush includes a car body provided with wheels arranged on the bottom, a drive mechanism arranged on the car body and used for supplying power to the whole sweeping car, a brush arranged at an end of the car body and provided with a bracket and multiple bristles facing the ground and arranged on the bracket, a first transmission mechanism arranged between the drive mechanism and the brush and used for transmitting the power to the brush, a control mechanism provided with a control arm extending out from the other end of the car body. The control arm is provided with a control terminal connected to the drive mechanism.
