Title: Apparatus and method of position determination of a first mobile device using information from a second mobile device
Inventor: HOCKLEY GEORGE
IPC: G01S5/14
Filed: 2003-07-11
Abstract: A hybrid position determination system is disclosed. A mobile device may determine a number of pseudo ranges based on a first position determination system, such as a Global Positioning System. In instances where the position of the mobile device is underdetermined because of an insufficient number of satellite pseudo ranges, the mobile device receives shard position information from other devices. The other devices include a second mobile device. The first mobile device may determine its position based on an underdetermined number of satellite pseudo ranges by determining pseudo ranges to other mobile devices. In other embodiments, the number of satellite pseudo ranges may be insufficient to generate an absolute position determination of a single mobile device. In this underdetermined condition, mobile devices may determine a common location of the group or may determine a relative positioning of members of the group.

Title: Flat plate heat exchanger coil and method of operating the same
Inventor: DAWSON PETER
IPC: F28D9/00
Filed: 2005-01-25
Abstract: A flat plat plate heat exchanger coil typically used in a bulk material heat exchanger is provided. The flat plate heat exchanger coil is designed to operate under a negative internal pressure to eliminate depressions or dimples that are typically formed into the sides of these types of heat exchanger coils during the manufacture process. With the removal of the depressions or dimples the tendency for bulk material to accumulate to the exterior surface of the coil is reduced, thereby increasing the service period of the coil. The flat plate is also provided with methods of automated cleaning of the plate coil, such as applying a low positive internal pressure in a cyclic manner to dislodge material accumulated on the coil, bumping the coil to causing a shock wave through the coil or providing means to create a shearing effect between adjacent coils to dislodge material accumulated on the exterior of the coil.
