Abstract: There is provided, in accordance with an embodiment of the present invention, a system, platform and method to provide Automatic Inventory, VMI visibility and predictability, and automated Recipe generation and costing in a purchase management system. In one embodiment an automated inventory management system includes a food sales data source associated with a sales processing software; a food waste data source associated with products related to the sales data source; an order management system associated with food merchandise supply processing software; a recipe database including multiple recipes with associated raw material data, designed to extract raw material compositions from items ordered off a food product menu; and an automated inventory system adapted to automatically manage raw material based on sale data and purchase data, and to provide substantially real time inventory data.

Abstract: A method is provided for reducing the peak power level in a combination of orthogonal frequency division multiplexed (OFDM) tones. The method is particularly effective when the information to be communicated is digital data consisting of long patterns of “1”s or “0”s. The digital data of the message is combined with a scrambling vector before the data is modulated. The randomization of data patterns, in turn, leads to a more random combination of OFDM tone amplitude being transmitted. The message is recovered at the receiver by removing the scrambling vector. An OFDM communication system using the above-described method is also provided.
