Title: Flavor emitting compositions, devices and packaged food products therewith
Inventor: POWERS THOMAS
IPC: A23L27/00
Filed: 2008-08-19
Abstract: Instead of direct introduction into recipes of food products, for example, flavorant emitting compositions including at least one flavorant are in combination with a stabilizer, e.g., adsorbent or absorbent, and indirectly added to the food product via a closed environment of a package by readily releasing the flavorant from the substrate. When a device, such as a porous sachet comprising the compositions is placed in a closed environment of a food package, for example, a constant fresh aroma and/or taste is delivered to the closed atmosphere of the packaged foodstuff and deposited onto the foodstuff per se for preserving and maintaining product freshness for enhanced consumer acceptance. Representative packaged products would include snack foods, such as barbecue chips, potato chips, bakery products, to name but a few.

IPC: H04L27/18
Filed: 2006-11-13
Abstract: Data bits to be encoded are split into a plurality of subgroups. Each subgroup is encoded separately to generate a corresponding codeword. Selected subsets are removed from the corresponding codewords, leaving behind shortened codewords, and are many-to-one transformed to condensed bits. The final codeword is a combination of the shortened codewords and the condensed bits. A representation of the final codeword is decoded by being partitioned to a selected subset and a plurality of remaining subsets. Each remaining subset is decoded separately. If one of the decodings fails, the remaining subset whose decoding failed is decoded at least in part according to the selected subset. If the encoding and decoding are systematic then the selected subsets are of parity bits.
