Method and apparatus for autonomously fueling machinery operating at fracking sites. Apparatus includes a main tank with a plurality of fuel lines individually coupled to the fuel tank. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to the machinery tanks to be refueled. The apparatus further includes a cap detachably connected to the hoses and machinery tanks. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.

A building manager includes a communications interface configured to receive information from a smart energy grid. The building manager further includes an integrated control layer configured to receive inputs from and to provide outputs to a plurality of building subsystems. The integrated control layer includes a plurality of control algorithm modules configured to process the inputs and to determine the outputs. The building manager further includes a fault detection and diagnostics layer configured to use statistical analysis on the inputs received from the integrated control layer to detect and diagnose faults. The building manager yet further includes a demand response layer configured to process the information received from the smart energy grid to determine adjustments to the plurality of control algorithms of the integrated control layer.

A reservoir assembly comprising a lower manifold, an upper manifold, a reservoir body, a float member and a sensor system. The upper manifold has an upper cover placed over a central bore, and sealingly engaged therewith, the upper cover being at least partially transparent. The reservoir body has a lower end sealingly engaged with the lower manifold and the upper end sealingly engaged with the upper manifold. The float member is positioned within the reservoir and can slidably move between the upper and lower manifolds. The float member has an upper target that is substantially parallel to an upper cover positioned on the upper manifold. The sensor system has a float position sensor positioned over the upper cover and targeting the upper target of the float member to, in turn, determine the position of the float member relative to the float position sensor.

There is disclosed a probe used with a measurement instrument including a pulse circuit for generating pulses. A coaxial connector is secured to the probe case so that the probe case is electrically connected to the ground shield, A center rod has a top end received in the probe case and to extend into a process liquid. The center rod is electrically connected to the center terminal for conducting the pulses. Ground rods are spaced around the center rod and are secured to the probe case. The probe provides an open configuration less susceptible to build-up between the center rod and the ground rods. One or more of the ground rods may by tubes, connected to a flushing port, with nozzles for cleaning the enter rod. Another ground rod may be tubular for carrying a conductor connected to a bottom of the center rod for bottom-up measurement.

The present disclosure discloses a smart water dispenser and a control method thereof. The smart water dispenser includes: an electronically controlled switch for starting adding water to a cup when it is turned on and stopping adding water when it is turned off; a cup detection module for detecting a cup placed under an outlet of the smart water dispenser; and a water level detection module for detecting a water level of water in the cup when the water is being added to the cup under the outlet.

Techniques and mechanisms for determining constraints to be imposed on resource utilization by customers of an electric utility. In an embodiment, flexibility metrics are determined each for a different respective customer, the flexibility metrics each indicating a respective difference between a metric of resource utilization, and a respective constraint which is imposed on that resource utilization. The customers are ranked, relative to one another, based on the flexibility metrics, where the ranking is used as a basis for selecting one or more customers to accommodate a change to a power delivery service of the electric utility. In another embodiment, one or more updated utilization constraints are imposed each by a respective customer of one or more selected customers.

A method is disclosed for controlling a charge transfer of an electric vehicle using an electric vehicle charging station, a mobile device, and a cloud server. The method includes receiving, at a mobile device, a message for an electric vehicle of a user directly from the electric vehicle charging station, wherein a user of the mobile device is associated with the electric vehicle to be charged. The method also includes receiving the charging control signal from the cloud server via the mobile device at the electric vehicle charging station in response to authorizing a charging control signal using identification information and credit account information received from the mobile device, wherein the charging control signal is configured to adjust a parameter used to draw electric power from the electric vehicle charging station.
