Abstract: A system and method for utilizing a plurality of Transducer specification files (TSFs) stored in one or more TSF databases to configure a Transducer Correction Processor (TCP). An incoming audio stream from an audio signal source is provided to the TCP, with the TCP using the unique configuration of the Transducer (e.g., speaker) contained in the TSF, applies corrections to the audio stream to produce a corrected audio stream. The corrected audio stream compensates for temporal or frequency domain or other aberrations produced by the particular Transducer. Consequently, a sound field produced by the Transducer from the corrected audio stream is close to or identical to a sound field produced by a “perfect” Transducer from the incoming audio stream.

Abstract: A restaurant service monitors order status of member restaurants in near real time using a network of on-site service appliances disposed at the member restaurants. In addition, the on-site service appliances can be integrated with member restaurant point-of-sale systems to provide near real time updates to restaurant menus as they are made in the point-of-sale systems.
