Abstract: An improved constrained layer vibration dampening patch for use directly on substrates with rust protective coatings. The improved constrained layer vibration dampening patch includes a constraining layer, a dampening layer and a release liner. The improved constrained layer vibration dampening patch includes a dampening layer with about 10 to about 15 weight percent of a butyl rubber composition; about 1 to about 5 weight percent of a tackifier; about 20 to about 25 weight percent of a plasticizer; about 60 to about 65 weight percent of filler; and about 0.01 to 1 weight percent of colorant, wherein the composition is substantially free of a curing agent, and wherein the composition is free of any ethylene copolymers.

Abstract: Methods, systems, and computer program products for providing customized content over a network are provided. The method includes associating content with at least one of a domain name, group, and geography for an entity, the content relating to at least one of the domain name, group, and geography. For each entity, the method also includes storing results of the association in a database record that is mapped to a domain name. In response to receiving a request to access a resource by the entity, the method further includes obtaining a domain name of the entity utilizing address information provided in the request, searching a database for the domain name of the entity, retrieving the database record corresponding to the domain name, generating a resource that includes the content, and providing the entity with the resource.

Abstract: A measurement circuit for measuring input voltages in an automatic test system includes a pedestal source, a differential amplifier, and a feedback amplifier. The differential amplifier measures a “residue,” i.e., a difference between an input signal and a pedestal signal from the pedestal source, which is programmed to equal an expected input voltage. The feedback amplifier boosts the residue before it is presented to the differential amplifier, and thus allows the differential amplifier to be operated at lower gain than is typically used in conventional topologies. Consequently, the effect of the errors in the differential amplifier are reduced.
