US Classification:

455101, 455 331, 4552771

Abstract:

A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

Abstract:

Apparatuses described herein relate to a diesel particulate filter for use in a diesel engine exhaust system. The diesel particulate filter comprises a particulate filter having a plurality of filter flow channels configured to remove diesel exhaust particulates from a diesel exhaust stream. The plurality of filter flow channels are disposed for contact with the diesel exhaust stream and are coated with a three-way catalyst coating. The three-way catalyst coating may be configured to assist in soot oxidation during regeneration events as well as for the reduction of NOfrom the exhaust stream. The three-way catalyst coating may replace, or be used in addition to, a three-way catalyst of a diesel oxidation catalyst.
