Abstract: A industry wide computerized business to business exchange permits participants in the industry to satisfy their procurement needs and manage their supply chains from a single log on to the exchange. An exchange architecture provides a particularly convenient platform for implementation of the exchange. Users connect to a portal services subsystem. User systems connect to an integration services platform. A platform services subsystem provides services to the portal services and to the integration services subsystems and to application programs that can be accessed through those subsystems. The application programs may include, for example, electronic procurement, collaborative product development applications and supply chain management. XML serves as the information currency for the exchange.

Abstract: The present invention relates to an optical sensor of air borne acoustic waves. The sensor comprises means for producing mutually coherent optical sampling and reference beams, which may be combined to form an intermediate frequency carrier, the sampling beam being exposed to the acoustic field, in which acoustic wave induced density variations occur. These density variations produce a variation in the index of refraction and thereupon a phase modulation of the sampling beam. This phase modulation may be recovered by an optical detector and a phase detector as an electrical signal representative of the acoustic signal. The invention has application to security systems.

Abstract: A method for sensing acoustic energy as the energy passes from a more dense to a less dense medium while compensating for energy level loses that may have occurred along the acoustic path of the acoustic energy. The method may be used to replace a multi-sensor system for detecting acoustic energy. The method includes permitting the acoustic energy to progress from a first transmitting medium to a second transmitting medium, the first transmitting medium being more dense than the second transmitting medium and the first medium being contiguous with the second medium along a predetermined interface; disposing an optical sensor in the second medium so that at least a portion of the acoustic energy imposes a modulation proportional to the frequency components of the acoustic energy on a sampling light emitted by the optical sensor; and detecting at least a portion of the sampling light having modulation in response to the portion of the acoustic energy.

Abstract: A hinged inclined panel in cooperation with the tailgate and two side walls of a truck bed form a secure storage compartment within the truck bed which conceals articles therein. The inclined panel acts as a spoiler by reducing air drag normally caused by the upright tailgate. A secure locking means for the hinged panel is provided.
