Abstract: A system monitors gas flow and pressure to a gas appliance in a fluid network comprising an analyzer. The analyzer has a housing defining an inlet, an outlet, and an interior in fluid communication with the inlet and the outlet. At least one sensor is coupled to the analyzer and configured to generate at least one signal related to gas being supplied to the gas appliance. A smart device communicates with the analyzer, wherein the smart device has a user interface and is configured to monitor, store and display data. The smart device can present any or all of a plurality of parameters such as the flow of gas, a capacity of the flow of gas, a temperature, a pressure of the gas and the like to a user based on signals from sensors.

Abstract: A system for providing focused ultrasound may include a focused ultrasound probe including at least one transducer. At least one variable volume fluid bladder may be positioned between at least a portion of the transducer and tissue to be treated. The system may further include a reservoir containing fluid and a first pump operatively connected to the bladder and the reservoir. The first pump may be configured to move fluid into the bladder. A second pump may be operatively connected to the bladder and the reservoir. The second pump may be configured to move fluid out of the bladder.
