  • Publication number: 20230182967
    Abstract: A tamper-evident security device to be used in conjunction with a slidable closure on a carrier bag comprises a bottom component (positioned within the bag itself) and a top component attached to a front panel of the carrier bag so to be located over the bottom component. The top and bottom components are fixed together in an immovable form, and the top component includes a recess for supporting the slider mechanism of the slidable fastener. A lid component is coupled to the top component via a hinge element, wherein upon closure of the lid component over the top component, the slider mechanism of the fastener is fully enclosed. A provided frangible seal (included to indicate possible attempts to tamper with the closure) is attached to the security device, with an end portion of the top component including a cover tab to hold the frangible seal in place as the carrier bag is handled during transport.

  • Patent number: 11288909
    Abstract: A secure ballot collection system is formed of a removable container that may be positioned within a voting machine and used for collecting paper ballots as they are cast. The container itself is capable of being sealed after removal from the voting machine to ensure the security of the paper ballots. The removable container is placed on a raised floor platform that is also positioned within the interior of the voting machine. The platform provides easy access to the interior of the voting machine from a side opening and allows for the ballot container bag to be located at a height where it is relatively straightforward for an election official to place an “empty” container bag at the beginning of the voting process, and also remove a “filled” container bag at some point in time thereafter.
