    Abstract: Systems and methodologies are described that facilitate relocating an IP buffer from a conventional location in a user device handset to a radio-access network (RAN) interface in order to reduce acquisition delay in the user device. By performing IP buffering at the transmission side of a forward link transmission, acquisition time can be reduced by approximately 5-7 seconds. Additionally, a physical layer aware encoder can be employed, which has knowledge of transmission constraints associated with, for example, a conventional DVB-H transmission protocol, and can parse streaming media into 1-second segments that can be pre-packaged in a current superframe for display at a subsequent time.

    Abstract: Methods and systems for distributed arbitration in a push-to-talk communications system are disclosed. A server receives talk requests from user communications terminals in a push-to-talk communications system. The server generates state information based on the talk requests and delivers the state information to the user communications terminals. The user communications terminals execute a distributed arbitration algorithm to determine which user communications terminal should have possession of a communications channel among user communications terminals with simultaneously pending talk requests based on the state information.

    Abstract: A platinum group metal three-way conversion catalyst composition containing a high temperature catalytic component and a low temperature catalytic component has each catalytic component present as separate distinct particles in the same washcoat layer. The catalyst composition is prepared from a washcoat slurry containing a high temperature catalyst support material, and a low temperature catalyst support material, each support material being of sufficiently large particle size so as to prevent each support material forming a solution or a sol with the liquid medium of the slurry. The platinum group metal or metals can be impregnated into each support material either after formation of the washcoat on a non-porous refractory, metallic or pelletised substrate or before forming the washcoat slurry.
