  • Publication number: 20260061466
    Abstract: A system and method to control the cleaning of an electrostatic platen is disclosed. A clamping voltage is applied to the electrostatic platen when a workpiece is not disposed on the top surface of the platen. Over time, the deposition of material on the clamping surface causes changes in the current that is supplied to the platen when the clamping voltage is applied. By monitoring the current in this manner, it is possible to terminate the cleaning process when a sufficient amount of deposited material has been removed. Additionally, by monitoring the current, it is also possible to determine when a cleaning process is warranted.

  • Publication number: 20250315726
    Abstract: An effect of a measure implemented only in a limited period of time on a human flow is appropriately evaluated. A server computer is configured to acquire a generated traffic amount in a prediction target area and includes a measure registration unit configured to reflect an evaluation target measure to a feature of an implementation point in the prediction target area in an implementation period of time. A human flow prediction unit is configured to input a feature in the prediction target area in each period of time set by the measure registration unit and the generated traffic amount in a prediction target period of time to a time-series consideration route selection model trained by associating human flow information including movement and congestion in each period of time with a feature at each point in the prediction target area, and to predict a movement route of each prediction target.

  • Patent number: 11308158
    Abstract: Provided is an information processing system, including a processor, a storage device and a display device. The storage device stores images captured by imaging devices. If an image of a moving object is selected as a search query, then the processor executes a similarity search on the images stored in the storage device, with the selected image as the search query. The display device displays images attained as results of the similarity search. If an image of a moving object is added as a search query, then the processor executes a similarity search with all selected images as search queries. The display device updates images to be displayed such that images attained as results of the similarity search performed with all the selected images as the search queries are displayed.

  • Publication number: 20210239875
    Abstract: An alert output timing control apparatus is configured to hold an analysis target image and time information indicating a period of time time to be spent until alert is output, and output the analysis target image to a display apparatus. When the analysis target image is input to a model and it is determined that an alert target object is included in a photographic object of the analysis target image, the alert output timing control apparatus obtains a period of time time from the time information and performs control so that alert is output at timing that arrives when the obtained period of time time elapses since given timing after the analysis target image is output.
