A system includes a beverage sensor to distinguish one or more beverage states and to communicate the distinguished one or more beverage states to a processor as gameplay control inputs to the game.

The present disclosure relates to a urine monitoring method adapted to a urine monitoring device and a cloud server. The urine monitoring method includes the urine monitoring device detecting a real-time weight, the urine monitoring device sending the real-time weight to the cloud server through a communication interface, and the cloud server determining whether the real-time weight is less than a lower bound of a current weight or is greater than an upper bound of the current weight. If the real-time weight is either less than the lower bound of the current weight or greater than the upper bound of the current weight, the cloud server sends a signal to set the urine monitoring device as a urine volume warning status.

The measuring cup includes numerous embodiments configured for a user to precisely determine the cup contents without need to lift the cup to one's eye level or to lower the eye level to the level of the cup contents. The various embodiments include folding cups; cups having transparent passages in the wall; cups having adjustably positionable bottoms; cups having level indicator rods in the cup interior extending upward from the cup bottom; cups having one or more filaments extending across the cup interior; cups having rigid level indicators spanning the cup interior; cups having adjustably positionable level indicator tabs therein; cups having buoyant level indicator tabs adjustably positionable in the cup interior; and cups having removable clip-on scales extending down along the interior of the cup wall, the scales having a plurality of attachment points for the removable attachment of a level indicator tab at a desired attachment point.

A system for advance notification of replacing or ordering a water bottle based on historical consumption data, and a water dispenser. The system includes a server, a water dispenser, a weight sensor, and a user device. The weight sensor measures weights of a replaceable water bottle on the water dispenser at different times and transmits the weights back to the server, so as to make multiple determinations with respect to the weights and accordingly obtain the consumption of the replaceable water bottle over time, thereby reminding a user to replace the replaceable water bottle and to make a new order.

A triple authentication waste level monitoring system for an aircraft includes a point level sensor for monitoring a wastewater level within a waste tank, a load cell for measuring a weight of the waste tank, and a flush counter for counting a number of toilet flushes since a previous service to the waste tank. A controller receives data from these three sensors and determines whether the waste tank is at capacity. The controller can determine waste tank capacity whether or not the point level sensor is faulty and compares the sensor data with various thresholds to ensure accuracy of the waste tank fluid level determination.

A level sensor assembly (552) for estimating a level of a dielectric powder (412) in a container assembly (544) includes a first electrode member (554) that is coupled to the container assembly (544); a second electrode member (556) that is coupled to the container assembly (544): and a control system (424). The second electrode member (556) is spaced apart from the first electrode member (554) and configured so that powder (512) in the container assembly (544) is positioned at least partly between the electrode members (554) (556). The control system (424) utilizes a capacitance between the electrode members (554) (556) to estimate the level of the powder (512) in the container assembly (544).

A system for measuring a level of dry bulk material within a container has at least one vertical cable with a plurality of drag elements supported at spaced locations along a length of the cable. The drag elements each have at least one opening through which the cable extends. The vertical cable can be a single cable extending through the center of the drag elements, or multiple cables extending through spaced apart openings in the drag elements. A load cell is arranged to measure a cumulative weight of the cable and drag elements plus the downward force applied by the dry bulk material to the drag elements to provide a load cell signal proportional to the level of dry bulk material in the container. The drag elements can be provided in various shapes and configurations, including circular disks or cap-shaped elements having substantially flat horizontal upper surfaces.

A rail vehicle includes a truck having wheels for engaging a railroad track, a bolster supported by the truck, and a tank supported by the bolster for storing a lading. A measurement system measures the level of the lading within the tank and includes gauges and a controller. The gauges are disposed at selected points on the bolster for sensing at least one of lateral and longitudinal localized displacement experienced by the bolster during motion of the rail vehicle. The controller calculates the level of the lading within the tank and compensates for changes in the level of the lading during motion of the rail vehicle in response to signals generated by the gauges.
