Abstract: Methods and apparatus are described for improving the transmission of information over wireless communication channels. These techniques include determining available communication channels for transmitting information and determining possible physical layer packet sizes of the available channels. An information unit is partitioned into portions wherein the size of the portions are selected so as to match one of the physical layer packet sizes of the available communication channels. Another aspect is partitioning the information into a number of slices that correspond to the number of transmissions that occur during the information unit interval and assigning each partition to a corresponding transmission. The techniques can be used for various types of information, such as multimedia data, variable bit rate data streams, video data, or audio data. The techniques can also be used with various over the air interfaces, such as, Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS), Enhanced Data GSM  Environment (EDGE), or standards based on CDMA such as TIA/EIA-95-B (IS-95), TIA/EIA-98-C (IS-98), IS2000, HRPD, cdma2000, Wideband CDMA (WCDMA), and others.

Inventor: RUELKE CHARLES R
IPC: H04W36/20
Filed: 2005-09-14
Granted: 2010-03-23
Abstract: A method for maximizing intermodulation interference protection during a handoff between radio cell sites (300) includes scanning a plurality of radio channels (302) and measuring the signal power (307, 315) for at least one of the radio channels. One or more receiver attenuators (313) are then set based on the detection of intermodulation (IM) interference of the measured channel.

Title: Putty composition and method
Inventor: WROBLESKI JOHN
IPC: C09D201/00
Filed: 2006-11-21
Granted: 2012-09-11
Abstract: A reduced staining plumbers putty for substantially stain free installations is disclosed. The putty can contain combinations of polymers or oligomers, solvents, fillers and optional rubbery materials. The substantially oil-free combinations produce sufficiently stain-free compositions that can be used on porous stone, such as marble and granite, without damaging the appearance of the stone. The oil- free compositions of the invention have the effect of eliminating the greasy feeling to the hands of traditional putty. Disclosed putties can provide a degree of tackiness for adhesion and gap fill purposes during installation, as well as a degree of abrasiveness so that pressure from the tightening process will not cause the putty to slip. A lack of staining on most, if not all, surfaces traditionally used to finish kitchens and baths, including porous stones and other porous materials, such as unglazed ceramics characterizes the disclosed putties.
