Sentry

Abstract The present disclosure relates to a sensor for monitoring metabolic activity of a population of exo-electrogenic bacteria in response to one or more agents in oxygenated water or wastewater in a water or wastewater treatment system. The sensor comprises: at least one electrode pair comprising an anode and a cathode, the anode in electrical communication with the exo-electrogenic bacteria for receiving electrons therefrom; a current sensor for measuring electron flow between the anode and the cathode and producing an electrical output that correlates with metabolic activity of the exo-electrogenic bacteria; and a power source in electrical communication with the electrode pair for delivering a voltage across the electrode pair. A method, system, and exo-electrogenic bacteria used for monitoring and/or controlling one or more agents in oxygenated water or wastewater is also provided.

Abstract A plate carrier having at least some of a front carrier having front shoulder strap extensions formed integral to the front carrier, wherein the front shoulder strap extensions extend from a portion of the front carrier; and a back carrier having back shoulder strap extensions formed integral to the back carrier, wherein the back shoulder strap extensions extend from a portion of the back carrier, and wherein each of the back shoulder strap extensions includes a shoulder strap channel formed through at least a portion of the back shoulder strap extension such that at least a portion of one of the front shoulder strap extension may be received within at least a portion of each respective shoulder strap channel.

Abstract A safety system for preventing collisions includes presence detection sensors oriented to sense the presence of a person or machine within a first and a second field of monitoring, and providing a visual indicator indicative of the person and/or machine sensed within the first and second fields of monitoring.

Abstract A valve assembly for use with and extending from an underside of a vented manhole cover assembly. The valve assembly is operable between an open position, to enable gas to exit from the manhole, and a closed position, to prevent the flow of the fluid into the manhole. The valve assembly includes a valve body having a first opening and a second opening and a fluid passage extending between the first and second openings. The valve assembly further includes a drain hole extending through the valve body configured to allow fluid drain therethrough. The valve assembly also includes a valve member moveable between the open position and the closed position, such that in response to the fluid entering through the first opening, the valve member moves from the open position to the closed position to prevent the flow of the fluid into the manhole, and wherein in response to fluid draining through the drain hole, the valve member moves from the closed position to the open position.

Abstract A protective device prevents tampering with a pipe system. The system transmits fluid from an upstream end to a downstream end of the system. The protective device includes a pipe insert disposed within the system between the upstream and downstream ends, and a valve within the pipe insert. The valve is moveable between open and closed positions, wherein the open position opens the pipe insert, enabling transmission of the fluid through the pipe insert, and the closed position occludes the pipe insert, disabling transmission of the fluid through the pipe insert to the downstream end of the system. The device includes a sensor for disposition within the fluid to detect a target compound in the pipe insert. The valve moves from the open position to the closed position when the sensor detects the target compound.

Abstract A reinforced gasket for sealing a manhole, the gasket comprising a reinforcement ring having an upper surface and a generally planar lower surface; and a sealing assembly comprising a first ring and a second ring with an intermediate member extending between the first ring and the second ring, the intermediate member defining a contact surface; wherein the reinforcement ring is disposed between the first ring and the second ring of the sealing assembly such that the upper surface of the reinforcement ring is in contact with the contact surface of the seal ring.

Abstract A computing device configured to manage one or more computing devices of an enterprise is disclosed. The computing device includes a transceiver, a memory, and a processor. The memory may include instructions stored thereon, that when executed by the processor, cause the processor to provide a user interface comprising one or more data objects, receive a command via the user interface, validate the command, prepare a script based on the command, the script comprising computer-readable instructions configured to be executed by one or more remote servers, schedule the script to be executed by the one or more remote servers, and receive a result from the one or more remote servers. The script is configured to implement the command on the one or more remote servers in order to facilitate the management of the processing system of the enterprise.

Abstract A vented precipitation guarding manhole cover assembly, comprising: a manhole cover having a top exterior surface and a bottom interior surface; a vent opening extending through the manhole cover between the top and bottom surfaces; a valve assembly in fluid communication with the vent opening and extending from the bottom interior surface, the valve assembly configured to extend from the bottom interior surface at least partially inside the manhole, the valve assembly operable between an open position, to enable gas to exit from the manhole, and a closed position, to prevent the flow of fluid from the top exterior surface into the manhole.
