Embodiments disclosed herein includes temperature monitoring in cold supply chains. In this regard, electrical conductors are affixed to containers in respective patterns that enables a set of containers to be arranged in a particular configuration in which the electrical conductors provide electrical connections between electrical conductors and, in aggregate, creates a sensing network that is operable to measure temperature of respective ones of the containers.

A method and system for set point control of a liquid level in a conical tank is disclosed. The method includes receiving set point signal, R(s), summing the set point signal, R(s), with a negative feedback signal, d{tilde over (f)}(s), and generating set point error signal, E(s), which is used as feedback at the input to drive the liquid level in the conical tank to a desired set point, thus controlling the liquid level of conical tank so that external disturbance, df(s), is minimized.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.

A high-performance seafloor flexible oil storage system, solving the existing problems of high storage cost and difficult maintenance of crude oil in offshore oilfields, comprises, sequentially connected, an oil-water separator, a pressure pump, and an input riser extending downward below the sealevel; and a pipeline and multiple flexible oil storage tanks having the same structure with each communicated therewith through a control valve are arranged below the sealevel. One end of the pipeline is communicated with the input riser through a blocking valve and an input valve, and the other end further sequentially connected with an outlet booster pump, an output valve, and an output riser extending upwards above the sealevel and connected to a tanker through a cooler and an output pump. The flexible oil storage tank has a concrete counterweight connected thereunder for fixing it to a seabed. The system has simple structure, convenient maintenance and good practicability.

Systems and methods for remote monitoring of a container are disclosed. The system includes at least one data collector configured to collect data corresponding to a physical attribute of the container, a wireless transmitter in communication with the at least one data collector and configured to transmit the data corresponding to a physical attribute of the container to a location remote from the location of the container, a server in communication with the wireless transmitter to receive and process the data corresponding to a physical attribute of the container, and a physical attribute analysis engine in communication with the server to receive the data corresponding to a physical attribute of the container and calculate a current value for the physical attribute based upon the received data.

An enhanced shipping container apparatus that maintains packages is described having integrated fire suppression. The apparatus has a container base supporting the packages, multiple container walls coupled to the container base, and a container top coupled to each of the container walls. A fire suppression panel is integrated as part of one or more of the walls and top portion, and has a support sheet of fire resistant material; an interior exposed sheet of temperature sensitive material; a sealed boundary connecting the support sheet and interior exposed sheet on peripheral edges (where the sealed boundary, support sheet and interior exposed sheet define a holding cavity), and integrated fire suppression material in the holding cavity. The temperature sensitive material of the interior exposed sheet releases the integrated fire suppressant material from within the holding cavity when the temperature sensitive material of the interior exposed sheet is exposed to a threshold temperature.

A system includes first and second sensors, and a controller. The first and second sensors are operable to attach to a water tank that supplies a building with water. The first sensor is configured to determine that a water level in the tank has fallen below a first level. The second sensor is configured to determine that the water level has risen to at least a second level. The controller includes a processor that is communicatively coupled to the sensors. The processor receives, from the first sensor, an indication that the water level has fallen below the first level. In response, the processor generates a signal to activate a pump that delivers water to the tank. The processor additionally receives, from the second sensor, an indication that the water level has risen to at least the second level. In response, the processor generates a signal to deactivate the pump.
