A system and method for monitoring and recording methane emissions from a source of methane. In some aspects, apparatus and methods are provided for converting the emitted methane to a different compound such as carbon dioxide.

A powertrain controller of a vehicle provides a fuel pump actuator signal indicative of fuel flow to a vehicle bus. A processor is configured to receive data from the vehicle bus. The processor performs an integration of the actuator signal to accumulate fuel usage of the vehicle, and periodically sends the accumulated fuel usage, vehicle speed, engine speed, engine status, and vehicle location to a remote server. A subset of accumulated fuel usage is retrieved for a set of the vehicles of a fleet traversing a route during a timeframe, the accumulated fuel usage compiled from fuel pump actuator signals. Fuel waste is computed for identified idle time periods within the accumulated fuel usage. Monetary waste is computed from the fuel waste. A report is generated including the monetary waste.

Apparatuses, methods, systems, and program products are disclosed for low-fuel indicator enablement based on fuel station locations. An apparatus includes a processor and a memory that stores code executable by the processor. The memory stores code executable by the processor to calculate a current fuel range for a vehicle. The memory stores code executable by the processor to determine locations of fuel stations within a proximity of the vehicle. The memory stores code executable by the processor to enable a low-fuel indicator for the vehicle in response to the current fuel range of the vehicle being less than a threshold fuel range as determined based on the locations of the fuel stations.

A plumbing fixture assembly including a fluid flow detection system for monitoring fluid flow and flow characteristics through plumbing fixtures without contacting the fluid. The fluid flow detection system communicates collected data related to the plumbing fixtures to a water management system, which analyzes the data and provides information to a user through a portal and user interface. The fluid flow detection system also tracks users of the plumbing fixtures for compliance with a hand washing routine. The hand washing compliance data is communicated to the water management system as well.

An expedited preflight readiness system for aircraft includes a power source having one or more battery modules for storing electrical power. An integrated controller is electrically and communicatively coupled with the power source for monitoring and controlling the power source to provide electrical power to aircraft subsystems. A mobile device is communicatively coupled with the integrated controller for communicating instructions to the integrated controller for initiating preflight readiness of the aircraft and for monitoring preflight readiness. A method for preconditioning an aircraft includes determining a state-of-charge of an APU and activating an environmental control subsystem for preconditioning the aircraft by adjusting a current temperature according to a preconditioning profile based on one or more of a target temperature, a target time, the current temperature, an outside air temperature, an amount of energy, and a state-of-charge of the APU.

A method for cementing a borehole includes pumping a collection of fluids into the borehole through a tubular string in the borehole, flowing the collection of fluids up an annulus positioned between the tubular string and a sidewall of the borehole, monitoring a volume of the fluids pumped into the borehole, performing a first estimation of a position of the fluids based on the volume of the collection of fluids pumped into the borehole, and an initial estimate of an average diameter of the sidewall of at least a portion of the borehole, calculating a corrected estimate of the average diameter based on the first estimation and a pressure of the fluids measured at an inlet of the tubular string, and performing a second estimation of the position of the fluids based on the volume of the fluids pumped into the borehole and the corrected estimate of the average diameter.

A pressure-regulating device for a fuel consumption measurement system includes a fuel supply line which supplies fuel to a consumer, a fuel return line, a bypass line which branches off from the fuel supply line, a pressure regulator which sets a free flow cross-section in the bypass line, a pressure sensor arranged at the fuel supply line downstream of where the bypass line branches off, a control unit electrically connected to the pressure sensor, and a pressure-reducing element arranged in the fuel supply line upstream of the pressure sensor and downstream of the branch of the bypass line. The bypass line fluidically connects the fuel supply line to the fuel return line and feeds fuel from the fuel supply line to the fuel return line while bypassing the consumer. The pressure sensor provides pressure measurement values. The control unit regulates the pressure regulator depending on the pressure measurement values.
