| 20080275607 | Method for Operating an Active Chassis System - A method is provided for operating an active chassis system, in which wheels of at least one axle are arranged with a toe-in angle, and actuating elements which interact with supporting assemblies which are arranged between the wheels and a vehicle body. Wheel contact forces of the wheels assume different values as a result of the actuating elements being actuated. A side force is generated at the wheels which have a toe-in angle, and a resulting yaw moment is produced. A desired yaw rate is determined based upon information from a device which is arranged in the vehicle in order to determine the profile of the roadway in a control unit, and the wheel contact forces are set as a function of the desired yaw rate. | 11-06-2008 |

| 20090179025 | RESISTOR ANODE ASSEMBLY - A sacrificial anode assembly. The sacrificial anode assembly includes a sacrificial anode, an insulator positioned around an end of the anode, an electric coupler positioned around the insulator and extending beyond the end of the anode, the electric coupler electrically isolated from the anode, a resistor having a first lead and a second lead, the first lead electrically connected to the anode and the second lead electrically connected to the electric coupler, and a cap positioned around the electric coupler, the cap electrically connected to the electric coupler and electrically isolated from the anode. The cap complete encapsulates the resistor, the first lead, and the second lead. | 07-16-2009 |
| 20090250017 | WATER HEATER WITH PRESSURIZED COMBUSTION - A water heater includes a sealed combustion chamber and one or more fans for raising pressure in the combustion chamber to increase efficiency of the water heater. The pressure permits a more restrictive baffle to be used in the flue compared to baffles used in atmospheric water heaters. The water heater may include a water temperature sensor that activates the fan without activating the burner if water temperature raises above a desired temperature. The water heater may also include pressure and vapor sensors to ensure the combustion chamber is properly sealed and there are no flammable vapors present prior to igniting the burner. The fans are relatively small and run off the same DC power that runs an electric gas valve. The fans may be, for example, 12 or 24 Volt fans with power inputs of about 10 Watts or less. | 10-08-2009 |

| 20080302784 | WATER STORAGE DEVICE HAVING A POWERED ANODE - A powered anode assembly. The powered anode assembly includes an electrode wire, a shield tube, and a connector assembly. The electrode wire has a first portion and a second portion. The shield tube substantially covers the first portion of the electrode wire, leaving a small portion of the first portion open. The connector assembly includes a connector that is electrically connected to the electrode wire, and a fastener that is physically coupled to but electrically isolated from the connector. | 12-11-2008 |
| 20090056644 | STORAGE-TYPE WATER HEATER HAVING TANK CONDITION MONITORING FEATURES - Methods and systems for evaluating the condition of a water tank having a powered anode protection system. The water heater includes a storage tank to hold water, a powered anode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to compare a measured parameter to a threshold. In some constructions, the threshold is indicative of a condition of the storage tank at which the powered anode is no longer able to protect the storage tank from corrosion. In other constructions, the threshold is predicative of a potential failure of the storage tank caused by corrosion. In some constructions, the control circuit is configured to estimate a time remaining until the predicted failure of the storage tank. | 03-05-2009 |
