摘要： A dialysis machine (e.g., a peritoneal dialysis machine) may include a housing. The machine may further include a leak detector disposed in the housing, the leak detector being an electrical circuit. In response to fluid contacting the leak detector, a leak in the dialysis machine is detectable. The machine is configured to send a signal based on a short of the electrical circuit from fluid contact with the leak detector to indicate a leak condition.

摘要： Embodiments of the disclosure are drawn to apparatus and methods for determining gas flux measurements. A gas plume may be emitted from a source and may be blown by wind in an environment. A measurement system, such as a light detection and ranging (lidar) system may collect a plurality of gas concentration measurements associated with the gas plume at a plurality of locations in the environment. A gas flux may be determined based on one or more of the gas concentration measurements along with a wind speed at a location associated with the gas plume. In some embodiments, a height of the gas plume may be determined, and the wind speed at the height of the gas plume may be determined and used to determine the gas flux.

摘要： Methods and systems are provided for a fluid leak diagnostic. In one example, a method may include intrusively increasing a fluid pump displacement to determine if an internal fluid leak is occurring. The method may further include adjusting a parking routine to determine if an external fluid leak is occurring.

摘要： A medical circuit board includes a substrate on which a wiring pattern is formed, a plurality of electronic components mounted in a mounting area on the substrate, a resinous sealing member covering the plurality of electronic components, with which the plurality of electronic components are sealed to the substrate, and a detection unit provided in an area other than the mounting area on the substrate and detecting an infiltration of a liquid from an interface between the substrate and the sealing member into the mounting area. At least a part of the detection unit is covered with the sealing member and sealed with the sealing member to the substrate.

摘要： A leak detection system comprising a substantially sealed accumulation chamber adapted to accommodate a single gas container, the accumulation chamber being sealed so that when a gas container is in the accumulation chamber gas leaked from that container accumulates. An optical detector is provided for detecting leaked gas, the detector including an optical cell. A controller directs a reference sample to the optical cell and subsequently directs a sample from the from the accumulation chamber to the optical cell. The optical detector is operable use both the reference sample and the accumulation chamber sample to detect leaked gas.

摘要： An apparatus includes a transmitter circuit configured to provide a transmitted waveform at a transmitter output, and a first microstrip differential trace extending from a first microstrip differential trace first end to a first microstrip differential trace second end. A first resistor has a first resistor first end coupled to the transmitter output and a first resistor second end coupled to the first microstrip differential trace first end. A second microstrip differential trace extends from a second microstrip differential trace first end to a second microstrip differential trace second end. A second resistor has a second resistor first end coupled to the transmitter output and a second resistor second end coupled to the second microstrip differential trace first end. A first receiver circuit has a first receiver circuit input coupled to the first microstrip differential trace second end, the first receiver configured to provide a first received signal. A second receiver circuit has a second receiver circuit input coupled to the second microstrip differential trace second end, the second receiver configured to provide a second received signal. A processor may receive the first received signal and the second received signal and perform digital signal processing on the first received signal and the second received signal, detect a coolant leak, and provide an alert upon detection of the coolant leak.

摘要： A liquid leak detector for a pump is described. The liquid leak detector is mountable on a pump to detect leaked fluid coming from the pump. The leak detector includes a buffer tube positioned on the pump to collect a leaked fluid from the pump and a sensor positioned on the buffer tube to detect the level of leaked fluid in the buffer tube and to generate a signal when the leaked fluid reaches a maximum fluid level. A purge line on the buffer tube removes leaked drive fluid from the buffer tube once the leaked drive fluid reaches a maximum level. Logic connected to the sensor receives the signal from the detector and generates an alarm.

摘要： A wall unit (V) for a retaining structure (100) comprises a foot portion (1a′) and a wall portion (1b′), wherein the wall portion (1b′) is inclined with respect to the foot portion (1a′), so that it extends over the foot portion (1a′). Accordingly, the wall unit (1′) is stable during construction and assembly. A corner unit (7′) for a retaining structure (100) is adapted to engage with two wall units (1′). A retaining structure (100) comprises at least one wall unit (1′).
