20110232890 | THERMAL MANAGEMENT METHODS - A thermal management system for a vehicle includes a heat exchanger having a thermal energy storage material provided therein, a first coolant loop thermally coupled to an electrochemical storage device located within the first coolant loop and to the heat exchanger, and a second coolant loop thermally coupled to the heat exchanger. The first and second coolant loops are configured to carry distinct thermal energy transfer media. The thermal management system also includes an interface configured to facilitate transfer of heat generated by an internal combustion engine to the heat exchanger via the second coolant loop in order to selectively deliver the heat to the electrochemical storage device. Thermal management methods are also provided. | 09-29-2011 |

20090101085 | SYSTEMS AND METHODS FOR CONTROLLING A WATER HEATER - A control for a water heater is provided that comprises a pressure switch for sensing a predetermined level of airflow sufficient for maintaining proper burner operation, and a temperature sensing means for sensing the temperature of the water in the tank. The control further comprises a processor for controlling the operation of the burner to maintain the water temperature above a predetermined value. When the processor receives a signal from the pressure switch or temperature switch indicating a malfunction, the processor shuts down the burner and subsequently attempts to restart the burner. The processor will lock-out further burner operation after a predetermined number of consecutive shut downs occurs, and will communicate any malfunction information to a remote display device. | 04-23-2009 |

20120227682 | Systems and Methods for Controlling a Water Heater - A control system for a water heater generally includes a water heater controller configured to receive upper and lower sensor temperatures associated with water in the respective upper and lower portions of the tank. The water heater controller is configured to determine a value indicative of a portion of water in the tank at a desired set-point temperature as a function of the upper sensor temperature, the lower sensor temperature, and the desired set-point temperature. The water heater controller is configured to wirelessly transmit at least one signal indicative of said value indicative of the portion of water in the tank at the desired set-point temperature. A user interface includes a plurality of selectively illuminated segmented portions. The user interface is configured to receive said value from the water heater controller and to selectively illuminate a number of segmented portions representative of said value. | 09-13-2012 |

20150316264 | PILOT BURNER ASSEMBLY AND METHOD OF ASSEMBLING SAME - A pilot burner assembly includes a bracket, a thermo-electric device configured to be connected to the bracket, and a unitary pilot guard. The bracket includes a first plate and a second plate spaced from the first plate. Each of the first and second plates have a pilot guard aperture defined therein. The pilot guard has a first end defining a gas inlet configured to receive a gas supply line, and a second end defining a gas outlet. The pilot guard includes an elongate body and a pilot hood disposed at the second end, and is configured be inserted into the pilot guard apertures. The pilot guard further includes a first retention element configured to cooperate with a second retention element on the gas supply line to maintain a connection between the pilot guard and the gas supply line. | 11-05-2015 |

20080219322 | Methods and apparatus for emitter detection - A method is provided for coordinating detection of emitted signals by a receiver with transmission of signals by a transmitter, wherein the receiver and the transmitter are located on the same platform. The receiver scans a surrounding environment to detect emitted signals in multiple frequency ranges while the transmitter transmits signals in a predetermined frequency range. The receiver may employ dwells which may be defined as receiver configurations. A dwell, when executed, may be used to detect signals in a certain frequency range. If a frequency range of the dwell conflicts with the frequency range of transmitter signals, which may result in interference of transmitter signals with detection of emitted signals, execution of the dwell may be delayed. If the frequency range of the dwell is such that transmitter signals do not interfere with execution of the dwell, the dwell can be executed. | 09-11-2008 |
