  • Patent number: 9845978
    Abstract: A heat pump water heater and systems and methods for its control. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.

  • Patent number: 9080776
    Abstract: A fan apparency arrangement for an appliance is disclosed. The appliance has a chamber with a first port and a second port. The arrangement includes a fan for moving air in or out of the chamber, and a sail switch disposed adjacent to the second port. When activated, the fan moves air in or out of the chamber through the first port to create a pressure difference between an inside and an outside of the chamber. The pressure difference causes the sail switch to change position and signal that the fan is activated. An appliance incorporating such a fan apparency arrangement is also disclosed.

  • Patent number: 8876491
    Abstract: This invention relates generally to a high volume, buoyancy controlled submersible pump assembly designed to sit on the bottom of a body of water or other liquid substance and move a large volume of water or liquid substance. Alternatively, the submersible pump assembly is capable of achieving and maintaining neutral buoyancy or near neutral buoyancy in a particular body of water or liquid substance. The neutrally buoyant version includes maintaining the pump assembly at a given depth without requiring it to sit on the bottom of the body of water or other liquid substance. This invention also relates to linear electrofusion for thermoplastic components.
