  • Patent number: 10533312
    Abstract: The present disclosure describes systems and apparatus for detecting an impending sewer backup by detecting fluid undulations of predetermined magnitude inside a main body of a backwater valve. When at least a predetermined number of fluid undulations of predetermined magnitude are detected within a predetermined time period, an alarm can be triggered. Such undulations can be detected by monitoring a buoyant gate in a normally-open backwater valve to detecting instances of movement of the gate from a lowered position in which fluid flow from an inlet through the backwater valve is unobstructed by the gate toward but stopping short of a raised position in which the gate closes the inlet to obstruct fluid flow through the valve. For example, a sensor can be carried on the gate to detect movement of the gate. Alternatively, fluid levels inside the main body can be monitored directly.

The second resin layer, the metal layer, and the protective layer in the upper film of the surface portion of the ink pack extend from the base layer (extended portion). The metal layer has a light-shielding property, and the extended portion is folded back and attached to the surface of the lower film of the side-surface portion. The metal layer having a light-shielding property thus covers the base layers exposed at the end surface of the joint portion, and can prevent external ultraviolet rays from reaching the ink through the base layers.

  • Patent number: 9177461
    Abstract: A portable solar-powered fluid level alarm system which uses a fluid level sensor electrically connected to electronic controls in a control box. The control box is mounted on an elongated member extending from a base which holds the system upright. The electronic controls within the control box operate up to four different alarms, including an audio alarm, a visual alarm, a remote notification signal via a global positioning system (“GPS”), and a remote notification signal via Voice over Internet Protocol (VoIP). The alarm system is also a keyed system so that once an alarm sounds only authorized personnel may deactivate it.

  • Patent number: 9127431
    Abstract: A manhole security cover includes a manhole cover body comprising a non-metallic RF signal transmissive material. The manhole cover body is seatable on a manhole frame to cover a manhole opening. In the seated position, the first side is accessible from outside the manhole, the second side is disposed within the manhole, and the peripheral edge portion engages a manhole cover support surface on the manhole frame. A manhole cover tamper sensor is responsive to a predetermined movement of the manhole security cover body. A transmitter is operatively connected to the manhole cover tamper sensor and configured to generate a radio frequency manhole cover tamper signal when the manhole cover tamper sensor detects the predetermined movement of the manhole security cover body. An antenna is operatively coupled to the transmitter to radiate radio frequency energy through the manhole cover body to a receiver located outside of said manhole.

  • Patent number: 9074587
    Abstract: A system includes a pump that is operative to move liquid out of a reservoir. The system also includes a depth level sensor that is operative to determine a depth level of the liquid in the reservoir, and a controller operatively connected to the depth level sensor. The system further includes a variable frequency drive operatively connected to the motor and the controller. Responsive to the determined depth level of the liquid increasing to a first level, the controller is operative to start operation of the motor. The variable frequency drive is operative to control the speed of the motor. The controller is operative to cause the variable frequency drive to output an optimum frequency that causes the motor to operate at substantially the lowest usage of energy to lower the depth level of the liquid in the reservoir from the first level to a second level.

  • Patent number: 8983667
    Abstract: A system is provided to control fluid flow in a wastewater treatment system through wastewater level manipulation. The wastewater treatment system may include a wastewater treatment plant connected to a plurality of pump stations by a main. Each of the plurality of pump stations may include a wet well with a pump therein. The system may include a central server in communication with a sensor to sense a level of wastewater within the wet well. The pump may be automatically moved to an on position when the level of the wastewater in the wet well is at or above a first level and may be automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level. The central server may systematically manipulate the first level to selectively set the level of wastewater within the wet well.

    Abstract: A server rack holds a number of modular servers configured for liquid cooling by passing a liquid coolant through interiors of the servers. Failure management of the cooling system is by management of the servers in segregated fault domains. Each fault domain comprises a number of the servers serviced by a dedicated coolant circuit that is segregated from the cooling circuits of the other fault domains. Potential liquid coolant leaks in a specific fault domain can be identified by monitoring liquid coolant levels in the respective coolant circuits. Each fault domain can include a separate, dedicated heat exchanger and a separate, dedicated coolant reservoir.
