    摘要: A digital synchronizer includes a latch connected to a level sensitive circuit. The latch is constructed to provide a rapid transition between logic "0" and logic "1". In addition, the latch is periodically cleared. The level sensitive circuit provides a propagation barrier to any metastable state that may be present in the latch. However, the level sensitive circuit is also constructed for rapid transition from logic "0" to logic "1" when such a state occurs within the latch. An additional latch is connected in a further embodiment to provide additional reliability of the synchronizer circuit. The second latch is a two inverter latch with refresh for 3/4 of a machine cycle to allow any transients conditions within the latch to dampen out.

    摘要: A method for configuring a computing device in a network of at least one remote device is disclosed. The method includes: storing, in a remote device, a configuration data archive relating to an existing computing device, wherein the remote device is at least one of a traffic camera or an aerial drone camera; determining, by a computing device to be configured, whether the remote device has stored therein a configuration data archive; and transferring data from the configuration data archive to the computing device to be configured in response to a determination that the remote device has stored therein a configuration data archive.

    摘要: Systems and methods for detecting potential theft and identifying individuals having a history of committing theft use an electromagnetic emission associated with a personal electronic device associated with an individual is received from at least one of a sensor that is coupled to at least one of a traffic camera or an aerial drone camera. One or more signal properties of the electromagnetic emission are analyzed to determine an emission signature. Video data and video analytics are correlated with the emission signature to identify the individual having possession of the item. The emission signature and video data are stored for later use during a checkout. If an emission signature detected at a checkout station matches that of the individual having possession of the item, and the item is not processed through the checkout station, an alert is issued and the individual is flagged as a potential shoplifter.

    摘要: An analytical recognition system includes one or more video cameras configured to capture video and a video analytics module configured to perform real-time video processing and analyzation of the captured video and generate non-video data. The video analytic module includes one or more algorithms configured to identify an abnormal situation. Each abnormal situation alerts the video analytics module to automatically issue an alert and track one or more objects or individuals by utilizing the one or more video cameras. The abnormal situation is selected from the group consisting of action of a particular individual, non-action of a particular individual, a temporal event, and an externally generated event.

    摘要: The present disclosure is directed to systems and methods for generating investigations of user behavior. In an example embodiment, the system includes a video camera configured to capture video of user activity, a video analytic module to perform real-time video processing of the captured video to generate non-video data from video, and a computer configured to receive the video and the non-video data from the video camera. The computer includes a video analytics module configured to analyze one of video and non-video data to identify occurrences of particular user behavior, and an investigation generation module configured to generate an investigation containing at least one video sequence of the particular user behavior. In some embodiments, the investigation is generated in near real time. The particular user behavior may be defined as an action, an inaction, a movement, a plurality of event occurrences, a temporal event and/or an externally-generated event.
