  • Patent number: 11706192
    Abstract: A cybersecurity infrastructure command validation system is provided herein for validating asset commands issued within an infrastructure network. The cybersecurity infrastructure command validation system can be integrated into an infrastructure network to monitor and validate infrastructure asset commands in real-time or while the infrastructure network is active. The cybersecurity infrastructure command validation system can receive or intercept commands issued by asset controllers. The cybersecurity infrastructure command validation system can validate the commands based on a command validation model. The command validation model can represent normal operating behavior of the infrastructure network. The cybersecurity infrastructure command validation system can provide valid commands to the intended infrastructure asset, or can reject invalid commands. The cybersecurity infrastructure command validation system can store validation results for use in updating the command validation model.

  • Patent number: 6827288
    Abstract: This above ground sprinkler system for a water supply provides a main supply hose having an inlet connected to the water supply and an outlet. A main valve is disposed between bib end of the hose and the water supply. A central station including a water supply inlet is connected to the main supply hose outlet and a plurality of hose outlets, each having an associated flow control valve, supplies water to sprinklers, or similar devices at the outer end of hoses which are connected at their inner ends to the outlets. A control system for directing the water supply to the individual hose outlets is provided including a timer. A relief valve is provided for draining water from the main supply hose and a backflow preventor valve is provided for preventing back-siphonage into the water supply.

  • Patent number: 6796273
    Abstract: The present invention relates to a water director for distributing a surge or flow of water to one or more of a plurality of output ports, which can vary in shape, size, and number, typically for use in marine and fresh water aquariums. Water pumped through a conduit into the hermetically sealed Switching Current Water Director (SCWD), powers an internally mounted gear driven fluid motor, which turns a rotational valve, alternately opening and closing a plurality of water outlet ports. When mounted externally to an aquarium, proper placement of output nozzles, which are connected to a water conduit attached to the various SCWD outlet ports, provides the desired opposing, or switching back and fourth currents. Depending on the inlet and outlet port configuration, the SCWD can be adapted to suit many applications.

  • Patent number: 6786234
    Abstract: The title flow regulator disclosed is used for regulating the level of water in the fields of an agricultural operation according to seasonal needs by a mechanism for adjusting the outflow of water from the tile line. The regulator includes a housing through which water from the tile line is directed and in which a partition with at least one aperture is positioned. At lease one vertically movable gate is associated each aperture and with a motor, an electric cylinder, and at least one actuator bar such that, upon actuation of the motor, the gate moves either open or close the aperture. If two apertures are included, the regulator can be fully open (both apertures open), fully closed (both apertures closed), or partially open (bottom aperture open, top one closed) to achieve the desired moisture level. Dates on which the gates will be moved can be pre-selected by remote signaling.

  • Patent number: 6779557
    Abstract: A multi-port rotary disc valve comprising a stator with a plurality of fluid flow ports and a rotary distributor with a plurality of channels arranged in a channel pattern. The channels are adapted to connect the ports between them and/or to the environment in a plurality of predetermined combinations, each combination being associated with an angular position of the rotary distributor with respect to the stator. The succession of combinations performed during a full or partial unidirectional turn of the rotary distributor constitute a predetermined sequence. The rotary distributor comprises a rotor and a mask mounted movably thereon, the rotor and the mask accommodating the plurality of channels. The mask is adapted to change the channel pattern by changing its position with respect to the rotor, thereby enabling the rotary disc valve to perform different predetermined sequences corresponding to different positions of the mask.

  • Patent number: 6755204
    Abstract: A land (56) on an index member (32) disposed in the interior chamber of a manifold (38) is aligned with an actuating member (34) and thereby holds open a check valve (36) through which fluid flows into the manifold's interior chamber, through a control valve (12), and out a manifold outlet (74). At the same time, another actuating pin (42) is so aligned with a recess (58) in the indexing member (32) as to permit another check valve (44) to prevent flow through itself into the manifold chamber. When the control valve is closed, flow stops, and pressure builds up in the manifold chamber. The index member (32) is accordingly driven against the force of a bias spring (48) to a lower position, in which a lower cam-follower surface (82) engages a lower cam surface (84). That engagement rotates the index member to a position in which it permits pressure to be communicated through both check valves (36 and 44) into the manifold chamber.
