Abstract: An ultra-wideband-based system and method for detecting properties associated with a movable object in an environment such as an indoor environment. The method includes transmitting ultra-wideband radar signals to an environment, using an ultra-wideband transmitter, and receiving signals reflected from the environment as a result of the transmission of the first ultra-wideband radar signals using an ultra-wideband receiver. The method also includes processing the reflected signals and determining properties associated with a movable object in an environment based on the processed reflected signals, using the processor.

Abstract: A method for material classification of an object. The method contains the steps of measuring, by a first light sensor, an intensity of a first light signal from an object; measuring, by a second light sensor, an intensity of a second light signal from the object; inputting features related to the intensity of the first light signal and features related to the intensity of the second light signal into a neural network; calculating by the neural network, for each of a plurality of possible classes of material, a probability of the object containing the material of the class; and determining a material of the object based on one of the plurality of possible classes of material that has a highest probability. Embodiments of the invention provide an automatic solution of material classification based on neural network, which achieves a high successful recognition rate of the material.

Abstract: A method for capturing and analyzing a motion of a user includes capturing a motion of a user represented by an RGB moving image and depth data, obtaining 2D skeletal data based on the RGB moving image, converting the 2D skeletal data to 3D skeletal data by mapping the 2D skeletal data with corresponding depth data, determining one or more key poses of the motion of the user based on a preset condition for each of the key poses, obtaining the one or more key poses of the motion of the user and segmenting a motion sequence by the key poses into segments, sampling each segment and aligning each segment with a corresponding segment of a set of standard key poses, and comparing trajectories obtained based on the aligned segments between the one or more key poses of the motion of the user and the set of standard key poses.

Abstract: A tool that is either hand-guided, or machine-guided, for performing surface treatments, such as mopping, of overhead surfaces includes a head for carrying an agitator having a generally planar face that is applied against the overhead surface being treated in uses. A transmission transmits power from a drive motor to the agitator, and an interface on the head is provided for connection to a mounting device by which the head is oriented and guided.
