Abstract: A system providing tactile sensations. The system comprises a seat back of a seat, the seat back having a left side and a right side separated by a center-line of the seat back. A first plurality of electroactive transducers are arranged along the center-line of the seat back and provide tactile sound to a user. A second plurality of electroactive transducers in the seat back provide tactile alerts or feedback. The second plurality of electroactive alert transducers comprise a left-side electroactive transducer at the left side of the seat back and right-side electroactive transducer at the right side of the seat back.

Abstract: A tactile sound device includes a transducer to convert an electrical signal into motion. One or membranes are coupled to the transducer and are adapted to transfer vibrations from the transducer to a user's body. A first sensor monitors the vibrations of the transducer. One or more circuits generate the electrical signal based on a signal received from the first sensor that monitors the vibrations of the transducer.

Abstract: The carbon footprint of a supply and distribution chain is modeled as a carbon dioxide (CO2) cost that can be considered alongside monetary or dollar ($) costs in supply, manufacturing, and distribution operations. Databases on products and services, supply chain policies, and targets, costs, and/or greenhouse gas (GHG) emissions are used by a GHG calculator to output carbon footprint data and/or by a supply chain optimizer to output supply chain planning and policy data. Client computers obtain carbon footprint and/or supply chain planning and policy data by querying a server with access to a database storing calculated carbon footprint data. Input data to the GHG calculator is updated based on choices made by users of the system.
