Abstract: An illuminating apparatus includes a support mechanism, an electric power system mounted on the support mechanism, and a sound and lamp assembly placed on the electric power system. The sound and lamp assembly includes a mounting rack, a lighting module, an acoustics module, a control circuit board, and a battery. Thus, the electric power system directly charges the sound and lamp assembly. In addition, the sound and lamp assembly includes a detection module that detects the charged state of the sound and lamp assembly, and regulates the lighting brightness according to the charged state, thereby prolonging the working time of the sound and lamp assembly after the sound and lamp assembly is removed from the electric power system.

Abstract: A lamp includes a housing, an adjusting knob, a sliding unit, a light source, and a lens. The housing is provided with a light output opening. The adjusting knob is mounted on the housing. The sliding unit is mounted in the housing and includes a sliding bracket which is provided with an elongate adjusting slot. A driving crankshaft is mounted on the adjusting knob and is located at a position deviated from a center of the adjusting knob. The driving crankshaft extends into the adjusting slot of the sliding unit. The light source is secured to the sliding unit and faces the lens. The lens is located in the light output opening of the housing.

Abstract: A five color temperature switching circuit includes a power supply, an LED driver, a first LED light, a second LED light, a third LED light, a first diode, a second diode, a third diode, a fourth diode, and a switch. The switch has twelve connecting ports. The switch has five regulating stages corresponding to the twelve connecting ports. Thus, the five color temperature switching circuit is provided with three LED lights with three different color temperature values, four diodes, and the switch, such that the lamp provides an illuminating function with five color temperature values.

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: A ceiling light fixture includes a mounting bracket, two retaining members pivotally mounted on two ends of the mounting bracket respectively, a light module mounted on the mounting bracket, and an outer disk mounted on the light module. The light module is retained by the two retaining members. The light module is provided with two connecting portions and a plurality of locking members. Each of the two connecting portions is provided with two retaining grooves locked onto one of the two retaining members. The outer disk is provided with a plurality of elastic plates. Each of the elastic plates of the outer disk is locked onto one of the locking members of the light module.

Abstract: Methods and systems are disclosed using linear expressions for machine learning (ML) models for ranking search results. In one example, a method for a computer trains a ML model into a decision tree for ranking search results. The decision tree is converted into a linear expression including Boolean terms. The linear expression is transmitted to one or more search computers that use the linear expression to rank search results for a search query. According to another example, a method for a computer having a search engine includes receiving a linear expression including Boolean terms representing a decision tree. The search engine processes a search query and uses the linear expression to rank search results for the search query.

The connecting unit includes a connecting board locked on the housing, and a connecting rod connected with the connecting board. Thus, the housing is mounted in the outer shell steadily by magnetism of the magnet.

Abstract: Systems and methods are provided for receiving and processing a query to determine an intent of the query, and analyzing the intent of the query to determine that the intent of the query is associated with a use case state diagram. Systems and methods further provide for traversing a plurality of nodes in the user case state diagram to generate a value for each relevant node, performing an operation associated with the query using the generated values, and providing the results of the operation to a computing device.

Abstract: Determining gait patterns and abnormalities of a user includes forming a plurality of point clouds corresponding to the user, each of the point clouds being three-dimensional coordinates of moving points, frame by frame, through a data capturing session, determining centroids of the point clouds, determining momentary walking velocities using estimates based on vectors connecting the centroids for adjacent frames captured during walking of the user, determining gait speed for the user based on the momentary walking velocities, determining at least one distribution of gait speeds for the user, and detecting gait abnormalities based on deviation of the gait speed from the at least one distribution of gait speeds. Detecting a plurality of point clouds may include using a tracking device to capture movements of the user. The tracking device may use radar and/or lidar. The system may determine a gait pattern of the user corresponding to routines of the user.
