    Abstract: A method for characterizing polarities of piezoelectric (PZT) elements of a two-element PZT microactuator mechanically coupled to a structure may include calculating an impedance of the two PZT element microactuator over a predetermined frequency range; summing the calculated impedance over the predetermined frequency range; and characterizing the polarities of the PZT elements of the two PZT element microactuator as being different if the summed impedance is greater than a threshold value and as being the same if the summed impedance is less than or equal to the threshold value.

    Abstract: In order to help music players without sufficient musical knowledge to adapt original music pieces but still keep the original style, the present invention provides an interactive system and the accompanying method for creating music by substituting audio tracks. The interactive system includes a database of musical elements that comprises tonality, tempo, beat, timbre, texture, chord, and pitch, a database of music that contains multiple original music pieces, and a processor. As a result, players without strong knowledge in music theories can create adapted a music piece that matches the style of the original one.

    Abstract: Method, device, and non-transitory computer-readable medium detecting a gathering of objects based on stereo vision are disclosed, and the method comprises steps of obtaining current and prior images and a corresponding depth map; extracting foreground pixels corresponding to detection objects from the current and prior images, and projecting the foreground pixels onto a ground surface to acquire a foreground projection image including foreground projection blocks; conducting, based on image feature differences of the foreground pixels between the current and prior images, projection onto the ground surface to acquire moving foreground projection blocks; utilizing the moving foreground projection blocks to erode the foreground projection blocks to obtain still foreground projection blocks; and determining, based on the still foreground projection blocks, whether the gathering of objects exists.

    Abstract: Disclosed are a shadow detection method and device. The method includes a step of obtaining a depth/disparity map and color/grayscale image from a two-lens camera or stereo camera; a step of detecting and acquiring plural foreground points; a step of projecting the acquired plural foreground points into a 3-dimensional coordinate system; a step of carrying out, in the 3-dimensional coordinate system, a clustering process with respect to the projected plural foreground points so as to divide the projected plural foreground points into one or more point clouds; a step of calculating density distribution of each of the one or more point clouds by adopting a principal component analysis algorithm so as to obtain one or more principal component values of the corresponding point cloud; and a step of determining, based on the one or more principal component values, whether the corresponding point cloud is a shadow.

    Abstract: The inventive system includes a host, a network including a security gateway, and a public application. Established are an access session between the network and the host and an application session between the public application and the network. An application session record is created for the application session, and includes the user's public user identity used to access the public application, the user's private user identity used to access the network, a host identity, and an application session time, To determine the private user identity for the application session, the security gateway sends a query with the host identity and the application session time. These are compared with the host identity and access session time in an access session record, if they match, then the private user identity in the access session record is returned, and it is stored as the private user identity in the application session record.
