摘要： A device for controlling the temperature of a swimming pool is disclosed. The device measures the temperature of the water as well as other environmental conditions (such as air temperature). The device controls a circulation pump, which circulates water throughout the pool. The pool water exchanges heat with the surfaces of the water (including the side walls, ground and surface air) when a heat differential exists between the water and the surfaces. When the water is circulated throughout the pool it increases the volume of water that exchanges heat with the surfaces, thus cooling or heating the water depending on the temperature of the surfaces. A target temperature is entered into the device and using this target temperature the device automatically controls the pump in order to take advantage of the heat exchange between the water and the water's surfaces to alter the water temperature in the direction of the target temperature. Additionally a heating element may be used to supplement the heating operation of the circulation pump.

摘要： An ultra-low sensitivity ground fault circuit interrupter (GFCI) device and a method for manufacturing the device is disclosed. The GFCI device detects an unbalanced current between line and return conductors that results from an unintended path to ground. The GFCI device disconnects the current source when a leakage current is detected. The GFCI device includes a current transformer that has its core wrapped with the line and return conductors. The line and return conductors are secured around the core in a fixed position. During manufacture of the GFCI device an amplifier of the GFCI can be adjusted so that the GFCI device disconnects the current source when a leakage current exceeds a desired level.
