Abstract: Search management systems and methods that cryptographically-secure search indices, search queries, and associated document records while in-use by cloud-based search software without requiring modification to the cloud-based search core software. The search proxy resides between a cloud-based vendor application and the cloud-based search software. The search proxy uses key-based deterministic cryptographic tokenization to irreversibly cryptographically-secure plaintext words from document records for indexing and plaintext keywords from search queries for search and retrieval. The search proxy separately uses key-based encryption on the document record's pre-tokenized plaintext words, adding the encrypted data as a separate field to the document record. This encrypted field is stored as part of the document by the search service.

Abstract: A flush-mount valve and vent assemblies including the same are described. A flush-mount valve may include a valve mount and a valve barrier which are coupled to the underside of a structure forming part of a liquid-impermeable container. The flush-mount valve is arranged to control the flow of fluid(s) across a fluid passage in the structure and is mounted to the structure so as to remain fully within the interior of the container.

Abstract: A system for controlling a thermal signature of a boat is disclosed. The system includes a fluid compartment adjacent to an external wall of the boat. The fluid compartment is disposed between a heat source in a hull cavity of the boat and the external wall of the boat such that heat energy released from the heat source is transferred to a fluid in the fluid compartment. A fluid mover moves a first volume of the fluid out of the fluid compartment and replaces at least a portion of the first volume with a second volume of fluid, wherein the second volume of fluid has a different temperature than the first volume of fluid before entering the fluid compartment.

Abstract: A marine vessel or watercraft may be provided with an aft extension that, in one configuration of the watercraft, alters the wake of the watercraft, for example by reducing the height of the wake, and which may include a sealable opening to provide crew or payload access into or out of the watercraft at a location (e.g., aft of the transom) that may be difficult for an observer to perceive. The aft extension may be positioned above the watercraft's waterline when the watercraft is in another configuration such that it does not contact with the water to reduce adverse impact on performance characteristics, such as drag, of the hull when the watercraft is in that configuration. The watercraft may transition between the two configuration by selectively varying the displacement of the watercraft or by articulating of the aft extension.

Abstract: A watercraft according to the present disclosure may include an outer hull that defines an interior or hull cavity, and a ballast system located within the hull cavity. The ballast system may include at least three ballast tanks longitudinally distributed along the hull cavity, and each of the tanks being configured to be independently operated enabling selective entrapment of ballast at three or more different longitudinal locations to enable an intentional shifting of the longitudinal center of gravity (LCG) of the watercraft relative to the design location of the LCG of the watercraft. The watercraft may include at least a forward, a center, and an aft ballast tank, and in some embodiments, additional tanks, in some cases in sponsons, may be included and/or one or more of the forward, center and aft tanks, may be further subdivided for additional active LCG control.

Abstract: Exemplary embodiments are directed to an apparatus for filling a central open space in a jar. The apparatus includes a base, an indexing station including a magazine, a blade, and a first actuator, a filling station including cartridges, and a second actuator. The magazine is rotatably mounted to the base. The platform of the cutting station is configured to receive a whole cucumber at a loading area and is incrementally indexed to reposition the whole cucumber from the loading area to a cutting area above the blade. The first actuator is configured to urge the whole cucumber through the blade and cut the whole cucumber into spears. The spears drop into and are held by one of the cartridges. The second actuator is configure to push at least one of the spears out from the cartridge into the central open space of the jar.

Abstract: A modular system, which may include a modular ramp for a landing craft, is described. For example, a ramp module according to some embodiments includes an enclosure defining a cavity, wherein the enclosure is configured to be removably received in a watertight recess formed in the hull of the landing craft. The ramp module also includes an extendible ramp operatively coupled to the enclosure and configured to be extended from the enclosure such that the ramp extends from the deck of the landing craft toward a shore to provide a support surface for unloading cargo onto or in close proximity to the shore. The extendible ramp is configured to be substantially fully retracted within the cavity, in some cases the enclosure forming an water tight seal with the recess in the hull and/or sealing the ramp, when retracted, in a water tight manner within its cavity.

Abstract: Described herein are examples of a watercraft with a hull defining a hull cavity. A canopy may be removably coupled to the hull via a canopy interface. The canopy interface includes a first portion fixed to the hull and a second portion fixed to the canopy. The first portion defines an opening through the hull into the hull cavity. The second portion is configured to be removably coupled to the first portion to enclose and seal the opening whereby the canopy interface is configured to interchangeably couple any one of a plurality of different canopies including the canopy to the hull. Each canopy of the plurality of different canopies may include a different configuration that provides a different access opening into the hull cavity or reconfigures the hull with a different outer profile.

Abstract: A vent assembly in accordance with some examples herein may include a vent conduit coupling a dry compartment of a boat to an opening in a hull of the boat for selectively fluidly connecting the dry compartment to an exterior of the hull. The vent assembly may include a fluid-tight ventilation closure which selectively prevents fluid flow through the vent conduit when the fluid-tight ventilation closure is in a closed position. The fluid-tight ventilation closure may be positioned below an exterior surface of the hull. A damper may be configured to selectively modulate air flow through the vent conduit. The damper may be positioned downstream of the fluid-tight ventilation closure from the opening.

Abstract: An integrated thruster and ballast system in accordance with some examples herein may include a conduit disposed within a hull of the boat. The conduit includes a first opening in fluid communication with a body of water, a second opening in selective fluid communication with the body of water, and an outlet disposed within the boat. The integrated thruster and ballast system includes a ballast tank in selective fluid communication with the conduit via the outlet, a thruster disposed within the conduit and configured to move water through the conduit, a first valve disposed in the conduit and configured to selectively divide or establish the fluid communication between the conduit and the ballast tank; and a second valve disposed in the conduit and configured to selectively divide or establish the fluid communication between the second opening and the body of water.
