摘要： A vehicular liquid containment system including a tank, a pressure sensor arranged to detect a pressure in a vapor dome inside the tank, at least two thermistors configured to detect temperatures at a plurality of levels of the tank, and leak detection logic operatively connected to the pressure sensor and the thermistors. The leak detection logic is configured to: use a first thermistor of the thermistors to perform a first measurement indicative of a temperature in the vapor dome in the tank; estimate an expected pressure evolution in function of at least the first temperature measurement; monitor pressure sensed by the pressure sensor, determine whether the monitored pressure deviates from the expected pressure evolution, and generate a leak condition signal conditional on the determining.

摘要： A system for sensing characteristics of a fluid contained within a tank. The system including an ultrasonic sensor, a temperature sensor, and a controller. The ultrasonic sensor is configured to output a ultrasonic pulse into the fluid, receive an echo of the ultrasonic pulse, and output a signal based on the received echo. The temperature sensor is configured to sense a temperature of the fluid and output a temperature signal corresponding to the temperature of the fluid. The controller is configured to determine a time-of-flight based on the output of the ultrasonic pulse and the received echo of the ultrasonic pulse, receive the temperature signal, determine a characteristic of the fluid based on the time-of-flight and the temperature signal, compare the characteristic of the fluid to a baseline characteristic, and output a signal based on the comparison between the characteristic of the fluid and the baseline characteristic.

摘要： A detector configured to indirectly monitor a level of liquid within a container is provided. The detector includes a temperature sensor and a heat producing element proximate to the temperature sensor. A shell is disposed around the temperature sensor and heat producing element, the shell is configured to be disposed within a container and to provide a barrier between liquid disposed within the container and each of the temperature sensor and heat producing element. The heat producing element is configured to transfer heat generated therein to the shell, and the sensor is configured to measure a surface temperature of the heat producing element.

摘要： A wireless remote monitoring system for biomedical fluid management that uses one or more sensors to detect changes in fluid or air in any container attached to a patient in order to monitor pre-surgical or post-surgical progress or complications. The sensors may be configured to monitor any type of container used to collect fluid or air from the human body, to transmit the sensor signals wirelessly to any number of devices including, but not limited to, cell phones or devices which in turn can send data to a functional repository where it can be analyzed and potentially acted upon by either a central or distributed network of providers.

摘要： Described herein are embodiments of a system for monitoring and detecting a level of a tank storing a material. The system may be used in making a determination of whether and/or when to provide additional material to the tank, to refill the tank partially or entirely. In some embodiments, the tank may be disposed at a premises such as a residence or commercial building and the system may be disposed in part at that premises to monitor the level of the material in the tank. In some embodiments, the material may be a fuel and the tank may be a fuel tank, to provide fuel to utilities equipment at the premises. In other embodiments, the tank may include other materials, such as other utilities materials. In some embodiments, the utilities material may be potable water.

摘要： The present invention relates to an electrolyte storage unit applicable to redox flow batteries and a vanadium redox flow battery including the same. The electrolyte storage unit for redox flow batteries of the present invention can be useful in minimizing a contact area of an electrolyte with the air to improve a self-discharge phenomenon of a battery and solving a problem such as an imbalance between a concentration and a volume of the electrolyte, which is caused during battery driving. Accordingly, a cycle of a process of regenerating an electrolyte can be delayed, and capacity and lifespan characteristics of the battery can be improved. Also, the electrolyte storage unit of the present invention can be easily handled and installed because electrolytes may not be easily mixed even by external impact.

摘要： Fluid containers having a volume marking(s) and conductive element(s) disposed at the volume marking(s) and a common conductive element are provided. For example, the fluid container has a wall forming the volume. The conductive element(s) and the common conductive element have a portion disposed within the volume and a portion external to the volume. The container further has a RFID tag, where the conductive element(s) and the common conductive element are connected thereto via respective conductive wires. A fluid detection system having the fluid containers is also provided. The system comprises one or more containers and a patient site monitor having a RF reader that interrogates the RFID tag at a preset interval. Responsive to the signal, the tag supplies a predetermined current to the conductive element and the common conductive element and detects a voltage and generates an alert based on the same.

摘要： A system (100) for and a method of monitoring water drainage is provided. The system for monitoring water drainage comprising a sensor interface (118), a storage (120), an atmospheric precipitation unit (130) and a signal generator (140). The sensor detects whether water is present at an associated surface (112) and generates a sensor signal (111). The storage stores water drainage information that relates to the associated surface and comprises characteristics of water presence on the associated surface in cases of atmospheric precipitation. The atmospheric precipitation unit receives recent atmospheric precipitation information. The signal generator i) obtains predicted water presence data by applying the water drainage information retrieved from the storage to the atmospheric precipitation information, ii) compares the sensor signal received from the sensor with the predicted water presence data, iii) generates a warning signal (151) indicating a problem with the water drainage if in the comparison a too large deviation is detected.
