Abstract: Systems, methods, and computer program products are configured to apply k-anonymity to an answer to a query sent to a relational database. A query to the relational database is obtained, the relational database containing a plurality of records. A frequency of occurrence of the attributes in the relational database is determined, an anonymization rule set is created based on the frequency of occurrence of the attributes, the anonymization rule set defining which attributes are to be suppressed in the answer to the query, the anonymization rule set is used to generate the answer to the query, wherein the answer to the query has k-anonymity, and a display or other device is controlled based on the answer to the query.

The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

Abstract: A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.

Abstract: An oceangoing vessel exhaust pipe coupling used to temporarily couple to an oceangoing vessel exhaust pipe. Installation and removal of the coupling only requires a simple mechanism with three translational degrees of freedom and one rotational degree of freedom, thereby enabling remote coupling. The coupling adapts to a wide array of exhaust pipe shapes and sizes. This is accomplished by a unique shape that allows stable and balanced resting position on top of an exhaust pipe as well as a two-chamber configuration, wherein the two chambers are separated by a permeable partition. Furthermore, the unique shapes of the chambers deflect the exhaust gas stream towards the outlet of the coupling, regardless of exhaust pipe style, thereby increasing capture efficiency and extending the life of an attached fabric flexible hose.

Abstract: STAXLINK™ is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.

Abstract: Given that power blackouts occur very infrequently, a TRANSportable GENset emissions reduction system (XGEN) that fixes a larger and more significant problem of reducing emissions from routine periodic testing of gensets, whereas the system may be scheduled to be shared by a multitude of gensets, thereby reducing costs through efficient use of capital expenditures while also increasing the quality of emissions reductions as compared to applying individual exhaust treatments each genset.

Abstract: A multi-circuit system for temporarily connecting to a plurality of exhaust pipes of an oceangoing vessel at berth or at anchor and treating captured exhaust gas. Each circuit includes an exhaust gas processing system, a duct system to reach from the processing system to an exhaust pipe; a duct inlet port for attachment to a connector receiving exhaust gas from an exhaust pipe. A positioning system supports the duct systems and connectors in a ganged relationship and positions the duct systems and connectors in a temporary operational position and in a non-operational position. In another embodiment, blower controller is responsive to a pressure measurement at the duct inlet port or the connector to control a blower speed to set or maintain the pressure to a desired pressure.

Abstract: A positionable emissions control watercraft that may be placed near a serviced watercraft in a location that is away from the risk of falling cargo, while also eliminating a need for a spacer or a spacer barge, and allowing other service watercraft to access the serviced watercraft.

Abstract: In accordance with one embodiment, a servicing watercraft that may be safely secured to a serviced watercraft. The servicing watercraft comprises at least one auxiliary section that may be positioned to either a) increase the effective width of the servicing watercraft thus reducing rolling motion while the servicing watercraft is stationary or in operation, OR b) decrease the width of the servicing watercraft thus reducing drag while the watercraft is moving through the water. Furthermore, the auxiliary section(s) help the servicing watercraft to be positioned in an optimum location adjacent to the serviced watercraft as to avoid impact from accidently dropped cargo or shipping containers from the serviced watercraft.

Abstract: In accordance with one embodiment, a self-propelled emissions control servicing watercraft that does not require transportation by tugboat and utilizes a hydraulic power unit that supplies hydraulic power to a hydraulic positioning arm during “service mode” and alternately uses the same hydraulic power unit to supply hydraulic power to hydraulic propulsion thrusters during “mobile mode”.

Abstract: A hybrid firearm receiver includes a receiver body having a first end, a second end opposite the first end, a substantially planar bottom surface extending from the first end to the second end and transitioning to two upwardly extending opposing sidewalls, and a top end, the receiver body extending along a longitudinal axis from the first end to the second end. The first end is integrally formed with the receiver body and includes a first outer face and a rail interface that facilitates receiving a clamping mount of a gunstock between side edges of the rail interface and the first outer face. The rail interface has a plurality of flats disposed along a first plane that is transverse and non-perpendicular to the axis. The top end, the two opposing sidewall, and the first end form trough extending transverse to the axis.

The parallel exhaust filter sections that may be heated and/or regenerated individually thereby facilitating catalyst temperature control and modulation of pressure drop across the exhaust filters.

Abstract: A liquid conservation device that utilizes a heat exchanger to condense water vapor from exhaust gas emanating from an exhaust treatment. Water evaporated during the emissions control process is recovered and returned for reuse, thereby significantly reducing the water requirement of the exhaust treatment. This is especially helpful for a mobile emissions control system that is normally not directly connected to a water utility.
