Embodiments of the invention include a method, an apparatus, a computer readable medium and a system for forecasting growth within a wireless telecommunications system. The method includes determining current system traffic for the wireless system, determining current minutes of use (MOU) for the current wireless system, estimating future MOU for the wireless system, and forecasting future system traffic for the wireless system based on the system's current traffic, current MOU, and future estimated MOU. The method also is useful for estimating spectrum requirements and balance between coexisting technologies, determining the impact of relief sectors proposed for the wireless system at future points in time, and determining the consequence of different system growth alternatives. Also, the growth forecasting method allocates the forecasted future system traffic throughout the existing system in a suitable manner, e.g., according to the percentage contribution of each system sector to the existing system traffic. The growth forecasting method incorporates growth factors and buffer amounts as part of the system traffic forecasting. For example, the future MOU estimating step can include MOU and subscriber count buffer amounts. Also, the future MOU estimating step can incorporate growth factors including an MOU growth factor and an individual sector busy hour (ISBH) growth factor to reflect system growth rates during peak usage and non-peak usage. The growth forecasting method is suitable for wireless systems that use one or more different existing technologies, e.g., Global System for Mobile Communications (GSM), Advanced Mobile Phone Service (AMPS), Time Division Multiple Access (TDMA), and Code Division Multiple Access (CDMA). Also, the growth forecasting method is compatible with existing system traffic offload algorithms.

An apparatus and method for forming flat top foam buns or slabs which features positioning solely one sheet of film material to each side of a rising foam body. The single side sheet is positioned in contact with the rising foam on one side and in contact with a rigid side wall on the opposite side. Also, the single side sheet positioned between the rising foam and stationary side wall represents the only material between the side wall and foam material. The side film has a bottom edge which originates below a reference plane lying flush on the bottom supporting surface of the foam bun once it has reached an essentially full rise position. Preferably, bottom and side conveyors are provided near the full rise position of the foam material and the side film is redirected from an upwardly inclined edge arrangement to a horizontal edge arrangement. Unwind assemblies are provided exterior to each of the side walls and are positioned such that the side sheets extend from a downstream position toward an upstream edge of the side walls, are wrapped around the upstream edge of the side walls and then directed at an incline. Roller sets or the like are provided to maintain the preset incline or a plurality of inclines of the film despite the disruptive forces of the expanding foam.

The present invention relates to a method of producing flexible polyurethane foam having reduced discoloration which utilizes low molecular weight alkanes or mixtures thereof as auxiliary blowing agents. More particularly, the present invention relates to the use of auxiliary blowing agents which are linear or branched alkanes having boiling points above -50. degree. C. and below 100. degree. C.
