Aspects of the present disclosure are directed toward systems and methods for detecting force applied to a distal tip of a medical catheter. In some embodiments, a medical catheter with a deformable body near a distal tip of the catheter deforms in response to a force applied at the distal tip, and a force sensor detects various components of the deformation. Processor circuitry may then, based on the detected components of the deformation, determine a force applied to the distal tip of the catheter.

Force sensing catheter system

Disclosed herein is an ablation catheter that includes an irrigation conduit, a force sensor, an electrode tip assembly, a seal, and a temperature sensor. The irrigation conduit defines an irrigation lumen configured to carry irrigation fluid to a distal end of the ablation catheter. The force sensors include a deformable body coupled to the irrigation conduit adjacent a distal end thereof. The electrode tip assembly is coupled to the deformable body and extends distally therefrom, and defines an interior cavity in fluid communication with the irrigation lumen and an exterior cavity in which a distal portion of the deformable body is received. The seal is disposed between the electrode tip assembly and the deformable body, and inhibits fluid flow between the interior cavity and the exterior cavity. The temperature sensor is coupled to the electrode tip assembly and extends from the electrode tip assembly through the irrigation lumen.

A water heater system including two or more water storage tanks plumbed in series, parallel or a combination thereof and methods of controlling said water heater systems. The water heater systems may include one or more mixing valves and one or more temperature sensors for providing water at a desired temperature.

Multi-tank water heater systems

A water heater system that includes a first water storage tank plumbed in series with a second water storage tank, and methods for controlling such a water heater system. In some instances, and in response to a water draw, a controller may activate both a first heat source associated with a first water storage tank and a second heat source associated for a second water storage tank. This rapid turn-on control may help reduce a drop in water temperature in the first water storage tank that might otherwise occur. The controller may also increase the setpoint temperature of the first water storage tank and/or the second water storage tank in response to a water draw.

A burner system for a furnace. The system may have a wedged or other shaped burner box. An air-fuel mixer may be attached to a smaller end of the burner box at virtually any angle relative to a direction of a gas and air mixture leaving the larger box end. A burner head may be attached to the larger end of the box. The burner head may be sufficient for numerous heater sections of a heat exchanger. A spacer and a radiation shield may be situated between the burner head and heat exchanger. An addition of the radiation shield may reduce the operating temperature of the burner box, burner head and/or spacer. A fan may move the gas and air mixture from the mixer, through the box and the burner head. The mixture may be ignited into a flame which is moved into the heat exchanger.

Valve control module

A method and system to position a non-immersion temperature sensor relative to a water heater tank is disclosed. An illustrative but non-limiting example may be found in a mounting bracket that includes a body that has a sensor portion configured to receive at least a portion of a temperature sensor assembly. When installed, the mounting bracket may include a biasing element to bias the temperature sensor assembly towards the water heater tank. The bias element may help the temperature sensor assume a proper position relative to the water heater tank, despite variations in equipment that may exist in the field.
