摘要:
A fixed network for automatically reading a utility meter system has been developed. The network includes multiple meter interface units (MIUs) that each collect data from a designated utility meter. The collected data is transmitted to a primary data collector. The network includes multiple data collectors and each MIU identifies its own primary data collector based on signal quality between the collector and the MIU. The network includes a central host computer that is used to receive the collected data from the primary data collectors.

Disclosed is a hot water heater supplement and means of utilizing waste heat from a refrigeration cycle. The apparatus comprises a refrigerator having a compressible refrigerant, a compressor, a condenser, a refrigerant receiver tank, an expansion valve and an evaporator for changing the temperature, pressure and phase of the refrigerant in a standard refrigeration cycle. The condenser is a coaxial, water cooled heat exchanger that receives waste heat from the high temperature, condensing refrigerant. The heated water is pumped into a coaxial heat exchanger within a heat exchange tank, which heats a volume of water within the exchange tank that is then mixed with a hot water heater tank for use in a residence. Cold water is fed into the exchange tank and thus pre-heated before being moved to the hot water heater, which utilizes either a gas or resistance style heating means.
摘要:
An assembly for providing either of auxiliary power and/or convective heating of an auxiliary exhaust, such as provided via a water jacket surrounding the engine exhaust interposed between an auxiliary generator and the truck tail pipe and circulated by a pump to provide heat to the cab interior. A further alternate variant provides for solar panels mounted to an exterior cab location and for operating the vehicle electric motor with or without the need for batteries. An associated articulating or pivoting mechanism is provided for displacing the solar panels from a first position in which it is stored against a rear surface of the cab, and to a second position in which is it arrayed upwardly above the cab.

A method for correcting data signal errors in a meter has been developed. The method includes receiving ordered data signals from the meter. Next, the sequenced of ordered data signals is analyzed to determine whether a data signal is missing. Finally, if a data signal is missing, a predetermined value is added to a sequence counter to compensate for the missing signal.

Detachable Clearance Wands are disclosed. The wands provide a driver of a large vehicle having slideout compartments with a clear dimension for the extension length of the slideout. The wands are attachable to the vehicle's side prior to parking it to provide the extension length without risk of damage to the slideout. The wands are length-adjustable so that they can be configured for any length slideout. In an alternate embodiment, the wands are comprised of several pieces of wand material interconnected to one another, such that the wand can be collapsed for consolidation and storage when not in use.

A wire bonder (900) with a rigid pedestal (902) having resilient inserts (920). A package (904) placed on the pedestal (902) contains an electrical device (906). The bond pads on the electrical device (906) are electrically connected to bond pads on the package (904) by a series of bond wires (908) through use of a well know bonding process. A vacuum source holds the package (904) against the pedestal (902) deforming the resilient strips (920) located in the rigid member (902) of the pedestal and ensuring good contact between the ground pads of the package (904) and conductive resilient members (920). The resilient members (920) are conductive and electrically connect the package grounds to a system ground (922).
