  • Publication number: 20220124154
    Abstract: A system can include multiple WiFi-enabled commercial off the shelf (COTS) Internet of Things (IoT) devices disposed within an environment and configured to be a transmitter (TX) or a received (RX) to send or receive data over a WiFi radio frequency communication link. A server can be configured to receive and parse the CSI data transmitted from the RX, store the CSI data with a corresponding human identity label collected for training, train a human identification classifier using a Convex Clustered Concurrent Shapelet Learning (C3SL) method, and estimate an identification of a user based on the CSI data and the C3SL method.

  • Publication number: 20210136617
    Abstract: A mobile device and user association system can include wireless routers to execute software for capturing data including received signal strength (RSS) values and media access controller (MAC) addresses for a number of mobile devices (MDs) from existing wireless fidelity (WiFi) traffic. The system can also include a server to receive the RSS values and MAC addresses of the MDs to estimate a location of each MD and generate historical location data of each MD, identify and filter out temporary MDs, classify each non-temporary MDs as either a static device (SD) or a mobile phone (MP), and associate a user with each SD and MP.

  • Publication number: 20060249729
    Abstract: A sensor apparatus for measuring a plasma process parameter for processing a workpiece. The sensor apparatus includes a base, an information processor supported on or in the base, and at least one sensor supported on or in the base. The at least one sensor includes at least one sensing element configured for measuring an electrical property of a plasma and at least one transducer coupled to the at least one sensing element. The transducer is configured so as to receive a signal from the sensing element and converting the signal into a second signal for input to the information processor.

  • Publication number: 20060089740
    Abstract: Presented are methods and apparatus for controlling the processing of a substrate during a process step that is sensitive to one or more process conditions. One embodiment includes a method performed with corresponding apparatus that includes a controller. One step includes constructing a perturbation model relating changes in control parameters for the apparatus to one or more resulting changes in the process. The method also includes the step of using the perturbation model with at least one of a performance objective and a constraint to derive optimized control parameters for the controller. Another step in the method includes operating the controller with the optimized control parameters. Another embodiment includes an apparatus for processing substrates where the apparatus comprises optimized control parameters.
