  • Patent number: 11263472
    Abstract: The disclosure includes a system and method for providing visual analysis focalized on a salient event. A video processing application receives a data stream from a capture device, determines an area of interest over an imaging area of the capture device, detects a salient event from the data stream, determines whether a location of the detected salient event is within the area of interest, and in response to the location of the salient event being within the area of interest, identifies a portion of the data stream, based on the salient event, on which to perform an action.

  • Patent number: 11157728
    Abstract: A method for person detection using overhead images includes receiving a depth image captured from an overhead viewpoint at a first location; detecting in the depth image for a target region indicative of a scene object within a height range; determining whether the detected target region has an area within a head size range; if within the head size range, determining whether the detected target region has a roundness value less than a maximum roundness value; if less than the maximum roundness value, classifying the detected target region as a head of a person and masking the classified target region in the depth image, where the masked region is excluded from detecting; and repeating the detecting to the masking to detect for and classify another target region in the depth image within the height range and outside of the masked region.

  • Publication number: 20210268728
    Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. Then, solutions of first and/or second binding agents are printed on the powder bed in a predetermined pattern. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The removable binding agent is then removed. The removable binding agent may be solubilized polyetheretherketone. Examples of solubilized polyetheretherketone include, but are not limited to, sulfonated polyetheretherketone and/or nitrated polyetheretherketone. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

  • Publication number: 20210272364
    Abstract: Image data describing a physical space is received from one or more sensor(s). A corresponding image of the physical space is output to a user. User generated control signals are received, indicating to define one or more line(s) at specific coordinates in relation to the physical space. One or more line(s) are defined in response to the received control signals. Polarity is assigned to the line(s), wherein crossing a line in a first direction is defined as an ingress and crossing a line in a second, opposite direction is defined as an egress. An image of the line(s) is superimposed on the image of the physical space, wherein the image of the line(s) graphically indicates the assigned polarity. Physical objects are monitored in relation to the one or more line(s) in the physical space. An action is automatically taken in response to activity detected by the monitoring.

  • Publication number: 20210271210
    Abstract: Logical boundaries enclosing a physical area are defined. A segment of the logical boundaries is defined as a directional gate, wherein traversing the gate into the physical area is defined as an ingress and traversing the gate out of the physical area is defined as an egress. The directional gate is monitored, and ingresses and egresses are detected. An occupancy count of the physical area is maintained, based on monitoring the gate and detecting ingresses and egresses. One or more conditions are tracked in addition to the occupancy count. Artificial intelligence (AI) processing is applied to the maintained occupancy count and the additional tracked condition(s), in real-time as the monitoring, maintaining and tracking are occurring. One or more responsive actions are automatically taken as a result of applying the AI processing to the maintained occupancy count and the additional tracked condition(s).

    Abstract: Methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing are provided. A layer of high performance polymer can be deposited on a build plate to form a powder bed. Then, a solution of a photothermal dye can be printed on the powder bed in a predetermined pattern. Alternatively, the photothermal dye can be added to the entire powder bed. Electromagnetic radiation can be applied, either to the entire bed or in a predetermined pattern, to form the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.
