  • Publication number: 20200228565
    Abstract: Certain aspects and features of the present disclosure relate to systems and methods for automatically classifying hosts in real-time. For instance, classifying hosts as bots, and subsequently mitigating or blocking traffic from the hosts classified as bots can be advantageous in real-time data exchange systems. In a real-time data exchange system, data can be exchanged between a server and a target host in real-time when the target host accesses a webpage. Inhibiting data communication between servers and hosts operated by bot scripts can reduce fraudulent activity. In some implementations, hosts can be automatically classified into various groups based at least in part on the data included in requests received from the hosts.

  • Patent number: 9988224
    Abstract: A removable media tray assembly for an image forming device according to one embodiment includes a media tray having a bottom surface and a front wall extending upward from the bottom surface. A bottom surface defines a media storage location for storing a stack of media sheets. The assembly includes a housing having an opening therein to receive the media tray. A magnet and a plate provide a latching force FL greater than a pick motor stall force keeping the media tray in a closed position during media picking. A handle assembly including a finger bar and a pivoting link is mounted to the front wall. With the media tray being held closed by the latching force, a user-supplied actuation force FA that is less than 22.2 N applied to the finger bar, pivots the link which acts as a force multiplier providing a release force exceeding the latching force.

  • Publication number: 20170316455
    Abstract: A system and methods for providing accurate counting of advertisement impressions is described. The system and methods include bloom filter technology or other space-efficient probabilistic data structure algorithms to efficiently determine whether any particular advertisement impression across an enormous set of possibilities has been viewed previously or not, without having to search through every instance of rendering of any particular advertisement impression. The present system and methods include arrays of multiple bloom filters and manipulate them to correct for false positives when conditions create the risk of false positives that may have occurred during data capture on a browser. In addition, the system and methods generate unique qualification identifiers for advertising served, which is evaluated by the bloom filters before a count is incremented.

  • Patent number: 9764912
    Abstract: A removable media tray with an adjustable rear tray extension operable by a rear media restraint. The tray extension is slidably attached to a front section of the tray via a cam having a locking arm engaged in a J-slot. When in the curved portion of the J-slot the front section and tray extension are locked together. A rear media restraint slidably latching to a track in the bottom of the tray has a locking lobe that engages with a locking notch on the cam. As the media restraint is slid toward the rear, the locking lobe initially rotates the cam moving the locking arm to the straight section of the J-slot, then the locking lobe engages with the locking notch, locking the media restraint to the tray extension. Thereafter, the media restraint and tray extension move together until the end of the J-slot is reached by the locking arm.
