A leak and/or overflow detection system for an aircraft may comprise a first sensor configured to be disposed in a toilet bowl, a second sensor configured to be disposed in a waste tank, a first acoustic emission sensor and a second acoustic emission sensor configured to be disposed upstream and downstream of a valve, or any combination of the first sensor, the second sensor, and the acoustic emission sensors. A controller may receive various data from the sensors and determine whether a leak and/or an overflow condition is occurring or about to occur.

A control system for monitoring an antimicrobial application system may include a controller having a monitoring program including an operations unit and an interface unit. The operations unit may include a sensor module operatively coupled to a plurality of sensors positioned to detect operation data associated with the application system in real-time. An adjustment module may adjust the operation of the application system. An analysis module may analyze real-time operation data and initiate a specified response when the analysis indicates that a trigger event has occurred. The response may include issuing a notification to a notification device or initiating the adjustment module to perform a control operation to modify the operation of the antimicrobial application system. A remote monitoring center may control multiple and remote application systems. Mobile devices and a control panel may be operable to interface with operations of the antimicrobial application system via the control system.

In one implementation, the specification discloses a liquid level sensor and communication device, system and/or method. In some implementations, the communication light weight portable, interactive device for personal or interpersonal non-video communication using voice messaging comprising a substantially thin polylateral shaped housing unit comprising: a) a front cover, a back cover and side walls connecting the front cover with the back cover; b) a digital sound recording unit configured with a manual switch for activating and recording a message; c) a digital sound storage unit; d) a playback unit configured with a manual switch for activating and playing back the recorded message; e) a microphone; and f) a speaker; and optionally, i) a light emitting device (LED) indicator or an audio indicator or a combination thereof, for indicating or alerting the presence of a recorded message; and/or ii) a manual ON/OFF switch for turning on and turning off the device when the device is not in use; wherein the sound recording unit, sound storage unit, playback unit, microphone and speaker are configured to allow a user to record a message and playback the message using the manual switches; and methods for using the device and/or iii) on/off switch also have a learning mechanism, by placing the unit on the empty part of the container and pressing on/off a number of times. Then the unit will learn the specifics of the bottle and will react to the filled portion of the bottle.

A universal sensor interface system includes a sensor assembly and an adapter with twist to lock and twist to unlock functionality. The sensor assembly has a sensor interface box and a transducer communicatively connected to the sensor interface box by a cable. The adapter is configured to connect to an access aperture of a container for holding a fluid. The sensor interface box has a first connection interface, and the adapter has a complementary second connection interface. The first connection interface and the second connection interface cooperate to facilitate connection of the sensor assembly to the access aperture of the container and disconnection of the sensor assembly from the access aperture of the container.

A level indicating device for a tank includes: a differential pressure type level gauge configured to measure a level of a fluid in a tank on the basis of a pressure according to the level of the fluid in the tank; and a level indicator configured to indicate the level of the fluid by moving in a vertical direction according to a differential pressure signal measured by the differential pressure type level gauge.

The instant application pertains to new liquid level monitoring apparatus and a cooling system for computer components that employs the liquid level monitoring apparatus. In one embodiment, the liquid level measurement device comprises a load cell and a buoyancy element. The buoyancy element is configured to be partially submerged in a dielectric liquid. The load cell and the buoyancy element are operably connected such that a change in liquid volume may be determined using Archimedes' principle.

The present disclosure relates to wastewater management that provides method and system for monitoring sewer manhole from a remote location. Sewer monitoring system configured in a sewer manhole receives measured values from level sensor and determines accuracy error in the measured values for different conditions. Thereafter, sewer monitoring system resolves the accuracy error in the measured values to obtain accurate measured values by either measuring level of wastewater in the sewer manhole by setting first range limit for the measured values dynamically based on actual depth of sewer manhole, or iteratively measuring level of wastewater in the sewer manhole by setting unique second range limit for the measured values dynamically. Finally, a risk associated with the sewer manhole based on the accurate measured values of the level sensor is determined, for monitoring the sewer manhole from a remote location.

A model-based method for quantifying a specimen. The method includes providing a specimen, capturing images of the specimen while illuminated by multiple spectra at different nominal wavelengths, and exposures, and classifying the specimen into various class types comprising one or more of serum or plasma portion, settled blood portion, gel separator (if used), air, tube, label, or cap; and quantifying of the specimen. Quantifying includes determining one or more of: a location of a liquid-air interface, a location of a serum-blood interface, a location of a serum-gel interface, a location of a blood-gel interface, a volume and/or a depth of the serum or plasma portion, or a volume and/or a depth of the settled blood portion. Quality check modules and specimen testing apparatus adapted to carry out the method are described, as are other aspects.
