Abstract: Detecting multiple people in a room includes detecting a point cloud corresponding to at least one user moving in the room, forming a bounding box corresponding to coordinates of points of the point cloud, and determining if the point cloud corresponds to multiple people based on a size of the point cloud, a presence of separate clusters of points in the point cloud, and/or detecting one or more people entering or leaving the room. Detecting a point cloud may include using a tracking device. The size of the point cloud may be compared with a size of a point cloud corresponding to a single user of the room. Detecting one or more people entering or leaving the room may include previously detecting entrances of the room by tracking movement of people in the room and determining a location where movement results in more or less people in the room.

Abstract: Determining sleep patterns of a user includes detecting a plurality of point clouds, each corresponding to a different position of the user at different times, forming a plurality of bounding boxes, each corresponding to coordinates of captured points of one of the point clouds, creating a wake/sleep classifier based on features of the point clouds, determining sleep positions of the user as a function of time based on the bounding boxes, and determining sleep patterns of the user based on the sleep positions of the user and on results of the sleep/wake classifier. Detecting a plurality of point clouds may include using a tracking device to capture movements of the user. The features of the point clouds may include intermediate data that is determined using scalar velocities of points in the point clouds, absolute velocities of points in the point clouds, and/or counts of points in the point clouds.

Abstract: The present invention discloses a mobile platform and an operating method of the mobile platform. The mobile platform comprises: a base; a housing disposed above an upper surface of the base and forming a placement space placing a work device with the upper surface of the base; and a travel mechanism disposed below a lower surface of the base for driving the housing and the base to move, wherein the lower surface of the base is provided with a groove and a bottom of the housing is disposed outside of an edge of the base. Moreover, during movement of the mobile platform, a dripping liquid drips down along the housing when the mobile platform is in an upright state, and the dripping liquid drips into the groove when the mobile platform is in an inverted state.

Abstract: A remote controller, a method for drawing on a TV using the remote controller and a drawing system are disclosed. The remote controller includes a touch panel and a detector that detects operations on the touch panel. The touch panel receives drawing operation inputs from a user. The present disclosure provides a touch panel for the remote controller to achieve drawing operation, thereby realizing large-screen drawing operation on a TV, meeting the demand for large-area drawing at home, enhancing functionality for the TV and improving user experience.
