Operation of an overhead storage bin sensor used to monitor the volume consumed within the bin including a VOC sensor to monitor for material that may become overheated within the bin such as lithium ion batteries in electronics products is provided. Currently, fire or smoke detectors are not integrated into the storage bins leaving this area vulnerable to developing fires and outgassing of electronic components often stored by passengers. Early detection of such events can prevent propagation of fire on board an aircraft by rapidly reporting the event and giving the location of the event. The system described leverages other patents applied for including a wireless sensor network and storage volume sensors. The sensor monitors for outgassing of materials or smoldering material by monitoring the air quality within the bin space.

An arrangement for measuring a volume of a solid or liquid sample includes a first chamber for accommodating the sample; at least one second chamber connectable to the first chamber; a third chamber connectable to a gas supply source and connected to a gas entry path leading to at least one of the first chamber and the second chamber; a pressure sensor; plural gas paths comprising plural valves; a temperature equalization system configured to temper at least the first chamber, the second chamber and the third chamber to substantially a same temperature, wherein the gas paths and the valves are arranged and connected such as to allow, filling gas out of the third chamber into at least one of the first chamber and the second chamber, and measuring a pressure in at least one of the first chamber and the second chamber.

Systems and methods are provided for aligning a laser scanning device for measurement of a volume of a container. A method includes: causing an autonomous vehicle coupled to the laser scanning device to move to a location at a known distance from a reference circumference; generating data indicative of locations of points along a portion of the reference circumference; determining, based on the data, an alignment angle by which the autonomous vehicle is to steer such that an axis of the laser scanning device that intersects the container passes through a center axis of the container; causing the autonomous vehicle to steer by the alignment angle, such that the laser scanning device is thereby aligned normal to a tangent plane of a wall of the container; and measuring a plurality of horizontal offsets of the wall relative to the reference circumference for use in determining the volume.

An X-ray imaging apparatus is configured to acquire a plurality of pieces of slice image data from volume data, acquire a plurality of pieces of first processed image data by performing first processing, acquire a plurality of pieces of second processed image data by performing second processing, detect edges of the subject based on the acquired plurality of pieces of the second processed image data, and acquire edge image data including detected edges of the subject.

A system for processing delivery items, the system including a delivery item monitoring device comprising one or more sensor and a processor that is communicatively connected to the delivery item monitoring device and that is configured to perform operations comprising obtaining sensor data from the one or more sensor. The operations can also include calculating a depth of the received delivery items in the container based on the sensor data and generating an under-filled indicator, a transport indicator, or an over-filled indicator based on the depth of the received delivery items in the container. Furthermore, the operations can include transmitting the under-filled indicator, the transport indicator, or the over-filled indicator to a control system, wherein the under-filled indicator, the transport indicator, and the over-filled indicator designate how to process the container to the control system.

Examples of a leak detection system are disclosed. In one example according to aspects of the present disclosure, a leak detection system includes a housing defining an interior, the housing connected to a component of a water distribution system. The leak detection system also includes a leak detection sensor contained within the interior of the housing and configured to detect a leak within the water distribution system. Additionally, the leak detection system includes a digital signal processing circuit in communication with the leak detection sensor.

A wound fluid collection system includes a canister adapted to collect bodily fluids from a tissue site. The canister includes an acoustic transducer adapted and positioned to insonify a cavity within the canister, the cavity being defined by a wall of the canister and the bodily fluids collected within the canister. A resonant frequency may be calculated based on a resulting received signal from the insonification. The resonant frequency may indicate a volume of the cavity within the canister. The difference between a known volume of the canister and the calculated volume of the cavity provides the volume of bodily fluid collected in the canister.
