Abstract: A system with a plurality of microphones positioned at different locations, and a modification system in communication with the microphones. The modification system is configured to derive a plurality of audio signals from the plurality of microphones, compute a confidence score for each derived audio signal, and based on the computed confidence scores, use one derived audio signal to modify another audio signal.

Abstract: An audio device with a number of microphones that are configured into a microphone array. An audio signal processing system in communication with the microphone array is configured to derive a plurality of audio signals from the plurality of microphones, use prior audio data to operate a filter topology that processes audio signals so as to make the array more sensitive to desired sounds than to undesired sounds, categorize received sounds as one of desired sounds or undesired sounds, and use the categorized received sounds and the categories of the received sounds to modify the filter topology.

Abstract: The invention relates to an apparatus for warming food. The invention is energy efficient, allowing food to be kept warm for a significant duration while consuming less power than conventional food warmers. This allows the invention to be portable because it is not dependant on 120V AC power. Additionally, the invention provides evenly distributed heat maintaining a high level of appeal for all food in the warmer.

Abstract: The invention relates to a portable package and method for preparing a meal. A warm meal is prepared by taking dehydrated food within a package and combining it with non-boiling water. The mixture is then heated by an electrical, portable power source, such as a battery or vehicle power system. This allows a warm meal to be prepared almost anywhere, even without access to boiling water.

Abstract: A modular sleep system has a foundation unit, an support unit having an innerspring and a support surface covered with a friction material, and a comfort unit having compressible material encapsulated in a woven upholstery material which is engaged by the friction material on the support surface of the support unit to prevent lateral movement or sliding of the comfort unit relative to the support unit, without any fasteners between the support unit and the comfort unit. The comfort unit can be lifted vertically off of the support unit without release or use of any fasteners, to be turned over, fluffed or exchanged for a different comfort unit having different layers of internal materials, feature layers, and support characteristics.
