Abstract: A safety circuit to disrupt power to a heating element of an appliance to be powered through a solid state switch (Tri-ac, Q1), typically a triac, from an AC power source (V1) having a positive half cycle and a negative half cycle delivering power. A low resistance condition is sensed by detecting either the current through or voltage across the solid state switch during the positive half cycle and the negative half cycle of the AC power line, when the solid state AC switch is not actuated. A fault signal is generated to interrupt power to the heating element, preferably by a crowbar circuit opening a fuse, whenever the low resistance condition is detected.

Abstract: Disclosed is a temperature control and safety circuit for detecting the temperature of a PTC heating element and the status of a solid state switch powered by an AC power source in both a positive and a negative power voltage half cycle. The AC-powered solid state switch, e.g., a triac, is provided in series with a current sense resistor, the voltage drop across the resistor being proportional to current through the PTC heating element. A voltage shifting circuit is also provided for rendering a positive voltage to an analog to digital converter during both a positive and a negative half cycle. Preferably, the voltage input to the analog to digital converter controls, at least in part, the temperature of the PTC heating element and the status of the AC-powered solid state switch during both of the positive and negative half cycles.

Abstract: A first valve of a manifold for a fluid distribution system (“FDS”) regulates fluid flow to a first fluid handling device (“FHD”). A second valve of the manifold may communicate with a second FHD, reservoir, or recirculation line. A target flow condition for the manifold may be determined by a manifold control system (“MCS”) based on a device setting received from the first FHD. The MCS may determine an operation of the FDS based on the target flow condition, fluid flowrate, and supply device operational state. The operation may include the MCS controlling the supply device, first valve, and/or second valve to change the flowrate. The MCS may continuously operate a valve to maintain the target flow condition once exhibited. Fluid distribution systems, systems and methods for turning over an FDS including a manifold, and systems and methods for controlling operations of an FDS including multiple manifolds are also provided.
