  • Patent number: 11344987
    Abstract: A method for monitoring chatter in a machining process includes the following steps: collecting an original signal related to chatter in the machining process; for the original signal, obtaining a signal segment for calculation and analysis by updating data points in a sliding window with a set step-length, where the step-length refers to a number of data points updated every time in the sliding window, and is not greater than the size of the sliding window; calculating fractal dimensions of the signal segments in the sliding window by using a fractal algorithm; and comparing the calculated fractal dimension with an identification threshold to determine whether chatter occurs in the machining process. The measured signal does not need to be preprocessed by using the method, which can greatly improve calculation efficiency and can ensure accuracy of chatter identification.

  • Publication number: 20220058407
    Abstract: The disclosure provides for head pose and gaze angle estimation that includes using a face alignment method with an image of a two-dimensional (2D) face to generate a facial UV position image and facial UV texture image of the 2D face in which to decouple movement of the head and eyes of the 2D face. An eye UV texture image is extracted from the facial UV texture image and stored in a database. The eye region of the facial UV texture image may then be replaced with the eye UV texture image stored in the database to generate a modified facial UV texture image. The modified facial UV texture image is reconstructed to generate a modified 2D face image as training data stored in the database, and the head pose and gaze angles of a person are simultaneously estimated by training a convolutional neural network with the training data.

  • Publication number: 20210398938
    Abstract: A uniform pressure gang bonding device and fabrication method are presented using an expandable upper chamber with an elastic surface. Typically, the elastic surface is an elastomer material having a Young's modulus in a range of 40 to 1000 kilo-Pascal (kPA). After depositing a plurality of components overlying a substrate top surface, the substrate is positioned over the lower plate, with the top surface underlying and adjacent (in close proximity) to the elastic surface. The method creates a positive upper chamber medium pressure differential in the expandable upper chamber, causing the elastic surface to deform. For example, the positive upper chamber medium pressure differential may be in the range of 0.05 atmospheres (atm) and 10 atm. Typically, the elastic surface deforms between 0.5 millimeters (mm) and 20 mm, in response to the positive upper chamber medium pressure differential.

  • Publication number: 20210357670
    Abstract: The disclosure relates to technology for monitoring driver attentiveness in a vehicle. A driver distraction system collects vehicle data and scene information from the vehicle while traveling on a route. The vehicle data and scene information are then processed to generate a reference heat map. At the same time, the driver distraction system may capture a gaze of a driver to track a gaze direction and duration of the driver while driving the vehicle on the route. The gaze direction and duration are processed to generate a driver gaze heat map. The driver gaze heat map and reference heat map are analyzed to determine a level of driver distraction of the driver in the vehicle, and a recommendation or warning is output to the driver of the vehicle according to the level of driver distraction.

  • Patent number: 11099865
    Abstract: Techniques are described for auditing clipboard operations in virtual desktop environments. The auditing takes place by detecting clipboard operations that are being redirected between the virtual desktop and the client device and recording log entries containing information about each clipboard operation that was redirected. In order to reduce auditing potential noise information, the redirection process is modified to delay populating the clipboard and recording log entries until a paste operation or other request for the clipboard is detected. In some situations, the clipboard redirection may be blocked based on the auditing capability, such as in cases where the auditing cannot take place due to the client computing device lacking support for auditing the clipboard operation and recording the necessary log entry.
