Abstract: A residential retrofit brine reclamation system includes a brine reclamation control panel; a flow sensor; and a three-way valve. The control panel includes a controller with an adjustable timer. The flow sensor is electrically connected to the controller and is connected to a tee fitting via a push-connect fitting with tubing. The three-way valve is electrically connected to the controller and has a softener effluent inlet, a brine water return outlet, and a drain outlet. A method of brine reclamation includes installing the brine reclamation system onto a resin tank and a brine tank and programming the controller to set a regeneration cycle time. The system identifies the start of a regeneration mode by sensing a flow in a softener brine line and directs softener effluent into the valve inlet. After draining some of the softener effluent, the system closes the drain outlet and opens the brine tank return outlet.

Abstract: A hybrid distributed low voltage power system can include a primary power source that distributes a first low voltage (LV) energy during a first mode of operation to a plurality of first LV devices of a LV device system and fails to distribute the first LV energy to the plurality of first LV devices during a second mode of operation. The system can also include a secondary power source that distributes a second LV energy to at least one second LV device of the LV device system during the first mode of operation and during the second mode of operation. The plurality of first LV devices are not critical during the second mode of operation. The at least one second LV device is critical during the second mode of operation.

Abstract: A light fixture can include a lighting circuit comprising at least one light source and at least one discrete component. The light fixture can also include a power supply coupled to the lighting circuit, where the power supply provides a setting current to the at least one light source. The light fixture can further include a sensor that measures the setting current flowing to the at least one light source. The light fixture can also include a controller coupled to the power supply and the sensor, where the controller provides, in real time, a setting current correction signal to the power supply to adjust the setting current delivered to the at least one light source. The setting current correction signal can be calibrated to an actual value of the at least one discrete component of the lighting circuit.

Abstract: A supplemental lighting system includes a charging circuit having a reference voltage for the charging circuit set through changes to reference resistances, and/or having an output voltage, current or power set through a connector configuration. In one example, a battery storage connector can be used to select a particular resistance for setting the reference voltage. Additionally, a supplemental lighting system may have a rechargeable battery coupled to a low-voltage part of the circuit, for example protected by an isolation circuit. Furthermore, a lithium ion or similar rechargeable battery supply can include a circuit for allowing it to be used with a circuit designed for a NiCad powered system or with a circuit designed for a lithium ion powered system.
