Systems, methods, and devices are provided for determining a status of a container. Some example systems include a container configured to rotate such that material(s) that may be disposed within the container are able to exit the container due to gravitational force. The systems also include a device connected to the container, which includes an accelerometer configured to sense movement corresponding to the container discharging the material(s). Such systems may also include a processor and a memory, and the processor may be configured to receive accelerometer data from the accelerometer, determine a tilt angle of the container based on the accelerometer data, determine whether the tilt angle satisfies a predetermined threshold, and cause a user to be notified when the tilt angle satisfies the predetermined threshold. The predetermined threshold may be a value representative of an assumption that a certain amount of the material(s) has been removed from the container.

This disclosure includes a manhole cover locking device, system, and kit, each configured for locking a manhole cover in a closed position overtop an access opening of a container, the access opening being arranged at one end of a collar extending outwardly from the container, each comprising: a body; a mechanism for connecting the body to a pre-existing portion of the manhole collar or the container; and, a mechanism for securing the body to the manhole cover to prevent the opening of the manhole cover using a pre-existing portion of the manhole cover. Each mechanism may be tamper resistant. The disclosure also includes methods of installing and using the device, system, and kit.

A vehicle body. The vehicle body comprises a fluid transfer system integrated within the vehicle body. The fluid transfer system comprises a fluid evacuation system comprising a first fluid storage container, a fluid refill system comprising a second fluid storage container, a sensing system coupled to the fluid evacuation system and the fluid refill system, and a control circuit coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control circuit is configured to (1) determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and (2) determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A brine separation system based on density. The system senses brine density and directs brine having a low density to a standard brine storage area and brine having a high density to a heavy brine storage area using a sensor and valves coupled to a processor-based controller.

A safety device for a vehicle. The safety device includes a housing that is adapted to be engaged with the vehicle, and a safety arm that operably engages with the housing and is moveable between a stored position and an operating position relative to the housing. The safety arm has a first end that engages with the housing, a second end that is opposite to the first end and is spaced apart from the vehicle, and a longitudinal axis defined between the first end and the second end. The safety arm is a single, unitary member defined between the first end and the second end. The movement of the safety arm is entirely along the longitudinal axis that is non-parallel to or perpendicular to a longitudinal direction of the vehicle.

A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.

A vehicle includes a safety arm and a coupler on the safety arm. The coupler couples the first safety arm to the vehicle. The first safety arm is adapted to fall away from the vehicle without damaging the vehicle when the safety arm contacts an object.

A vehicle body. The vehicle body comprises a fluid transfer system integrated within the vehicle body. The fluid transfer system comprises a fluid evacuation system comprising a first fluid storage container, a fluid refill system comprising a second fluid storage container, a sensing system coupled to the fluid evacuation system and the fluid refill system, and a control circuit coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control circuit is configured to (1) determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and (2) determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A manufacturing system includes: a first tank configured to store generation fuel; a manufacturing device having a first power generation device configured to generate power using the generation fuel, the manufacturing device being configured to operate using power supplied from the first power generation device; and a transport robot configured to transport the generation fuel from the first tank to the manufacturing device.

The present invention relates to a method and apparatus (5) for determining a change in volume within a vessel (11) with regard to fluid (14) being added or removed from the vessel. The method involves measuring first and second surface levels (20, 20) of fluid (14) within the vessel (11) (with regard to fluid being added or removed therefrom), first and second roll values (23, 23) of the vessel, and first and second pitch values (26, 26) of the vessel. From these measurements, and in conjunction with the known interior dimensions and known interior total volume of the vessel, there are calculated first and second fluid volumes that are compared to determine a change in fluid within the vessel.
