20090010246 | Cordless telephone systems - A multimode home telephone system includes a computer, a base unit, a wireless handset and a wireless headset. The computer is programmed with a “soft phone” program to make and receive VOIP calls via the Internet and couple them to and from the base through a USB connection. The base is also coupled to a public switched telephone network (PSTN) and is operable to effect full duplex communication via both the PSTN and the Internet. The base, in turn, is wirelessly coupled to the handset via the DECT/UPCS protocol, and the handset is wirelessly coupled to the headset via the Bluetooth protocol, such that the user can selectively place and receive telephone calls via any one of the Internet, the PSTN or an optional Bluetooth enabled cell phone. Optionally, a DECT/UPCS enabled headset can communicate directly with the base in addition to or in lieu of the Bluetooth enabled headset. | 01-08-2009 |

20090065439 | METHOD AND DEVICE FOR PREVENTING CORROSION IN HOT WATER SYSTEMS UNDERGOING INTERMITTENT OPERATIONS - Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system undergoing a wet layup sequence to inhibit corrosion in the hot water system. The method includes separating the wet layup sequence into a plurality of phases. Each phase is either short-term or long-term and a subset of the short-term phases is optionally transitional. The method further includes defining one or more zones in the hot water system. At least one of the defined zones is selected for each phase and one or more of the selected zones include at least one ORP probe operable to measure the real-time ORP and communicate with a controller. The ORP probe(s) either intermittently or continuously measure the real-time ORP at operating temperature and pressure at one or more of the selected zones in one or more of the phases and transmit the measured real-time ORP to the controller. The real-time ORP is assessed to determine whether it conforms to an ORP setting for that phase.
