A system and method are disclosed for quantity analysis. A quantity identification of an amount of content included in a container is received from a container cover of the container. The quantity identification is analyzed along with a history of past quantity identifications received from the container cover over time to determine an analysis result. An action associated with the content of the container is performed based on the analysis result. A system and method are disclosed that include one or more devices that help users track remaining quantity and expiration of food (e.g., including beverages).

The present invention relates to a device and method for measuring the amount of a liquid chemical in a plant protection unmanned aerial vehicle (UAV). An ultrasonic sensor is adopted to measure a distance between a liquid chemical level in a liquid chemical measuring tube communicated with a liquid chemical tank and a top end of the liquid chemical measuring tube, and then a height of the liquid chemical in the liquid chemical tank is further determined according to an acquired attitude angle of the UAV and a distance between a central position of the liquid chemical measuring tube and a central position of the liquid chemical tank, thereby accurately measuring the amount of the liquid chemical in the liquid chemical tank of the UAV.

An apparatus and methods for tracking administering of medication by syringes is provided. The apparatus may include a plunger head for a syringe. The plunger head may include a transducer that sends and receives ultrasonic signals. The plunger may also include an antenna and a microcontroller that interfaces with the transducer and the antenna. The plunger may also include a power source that powers the microcontroller and the transducer. The transducer, the antenna, the microcontroller, and the power source may be at least partially encapsulated in an elastomer housing that fits within a barrel of the syringe. The microcontroller may be programmed with instructions to calculate data representative of the quantity of medication dispensed from the barrel and transmit the data to a remote device via the antenna.

Disclosed herein are a water purifying device and a method for controlling the same. The water purifying device is characterized in that a water discharge module capable of moving vertically is provided with a sensor. Specifically, in the water purifying device of one embodiment, the sensor may measure a height of a container, by transmitting and receiving a signal for measuring a distance at a first point of the water discharge module, and may detect both a height of the inlet of the container and a water level, by transmitting and receiving the signal and measuring a water level at a second point of the water discharge module.

An apparatus and method for multi-bounce acoustic signal material detection is provided. The apparatus includes a container containing a quantity of material therein, wherein the quantity of material has at least two segmented layers. First and second acoustic sensors are positioned on a sidewall of the container, wherein the first acoustic sensor is positioned at a different height along the sidewall than the second acoustic sensor. An acoustic signal is transmitted into the sidewall of the container from the first acoustic sensor. The acoustic signal reflects between an interior surface of the sidewall and an exterior surface of the sidewall until it is received at the second acoustic sensor. A border between the at least two segmented layers of the quantity of material is detectable based on the acoustic signal.

Disclosed is a system for automatically measuring a discharge in real time based on a CCTV image. The system includes: a water depth measurement device filtering water depth data measured by a measurement means with a local linear regression-based bivariate scatterplot smoothing technique through flexible bandwidth application to calculate the water depth of a stream; an image acquisition device acquiring a continuous image of a flow speed measurement side of the stream; an image analysis PC using an image of the image acquisition device to measure the surface flow speed in real time and receiving a measured water depth from the water depth measurement device to measure the discharge in real time with cross-section data; and a discharge calculation and management server for transmitting and displaying a real-time discharge measurement result based on a web.

Systems and methods for determining a fill level of a fluid within a fluid vessel, an identity of the fluid, and/or a condition of the vessel wall are disclosed. To determine a fluid fill level, at least one acoustic sensor is positionable substantially on an exterior sidewall of a vessel containing fluid. A computerized device is in communication with the at least one acoustic sensor. A processor of the computerized device receives a detection signal from the at least one acoustic sensor and communicates an alert of the detection signal, which can be used to identify a fill level of the fluid. The detection signal, along with other measured information, can be used to identify the material type of the fluid. A condition of the vessel wall may be determined based on an attenuation signal when two acoustic sensors are used, one being positioned angular to the vessel wall.
