Abstract: A helmet is provided that can include a cage defining a front end, a back end opposite the front end, a first lateral end and a second lateral end opposite the first lateral end. The cage can include multiple longitudinal beams that extend between the back end of the cage and the front end of the cage; and a transverse beam that extends between the first lateral end of the cage and the second lateral end of the cage. The transverse beam can be anchored to the multiple longitudinal beams. The helmet can include a body that fully encapsulates the multiple longitudinal beams of the cage and that partially encapsulates the transverse beam. The body can define multiple vents. Each vent can be situated between two adjacent longitudinal beams. The transverse beam can extend through one of the multiple vents.

Abstract: An apparatus for controlling access to a memory device comprising rows of memory units is provided. The apparatus comprises: an operation monitor configured to track memory operations to the rows of memory units of the memory device; a row hammer counter configured to determining, for each of the rows of memory units, row hammer effects experienced by the row of memory units due to the memory operations to the other rows of memory units of the memory device; a mitigation module configured to initiate, for each of the rows of memory units, row hammer mitigation in case that accumulated row hammer effects experienced by the row of memory units reach a predetermined threshold; and a virtual host module configured to perform the row hammer mitigation targeting a row of memory units in response to the initiation of row hammer mitigation for the row of memory units by the mitigation module.

Abstract: A merchant listing verification system to scan a publisher system of a set of publisher systems to identify a published merchant listing published by the publisher system, where the published merchant listing includes a first set of data fields and a first set of data field values associated with a merchant system. The merchant listing verification system compares, on a field-by-field basis, the published merchant system to a target merchant listing comprising a second set of data fields and a second set of data field values associated with the merchant system. Based on the comparing, a discrepancy between a first data value of a first data field of the first set of data fields of the published merchant listing and a second data value of a second data field of the second set of data fields of the target merchant listing is identified.
