Abstract: An ultrasound instrument for detecting a measured value of a medium includes a measurement chamber having a chamber wall and a longitudinal axis; a pair of ultrasound transducers configured to transmit ultrasound signals along a signal path between ultrasound transducers of the pair through the measurement chamber and to receive ultrasound signals, wherein the signal path includes a signal reflection on a reflection surface, wherein the chamber wall in a region of the reflection surface opposite a first chamber side is configured to prevent a reflection of an ultrasound signal on a chamber outer surface of the chamber wall in the direction of the signal path, wherein the chamber wall has, in the region of the reflection surface, a maximum wall thickness which is at least a factor of 1.5 greater than a Rayleigh wavelength, associated with a central frequency, of the ultrasound signal in the chamber wall.

Abstract: Systems and methods for parallel conversion, compilation, and distribution of content are disclosed. An application interface may be provided that enables a user to request the conversion of content items into formats well suited for presentation. The request may include a set of deliverables. Each deliverable may include an associated content item and a corresponding associated format to which to convert the associated content item. The request may be processed by a “pipeline” application. The pipeline application calls existing applications or proprietary applications associated with a delivery channel, and the pipeline application may customize the content items for conversion into the corresponding formats. The pipeline application may convert the associated content items using a plurality of parallel processing threads, each thread corresponding to an associated deliverable, whereby each thread converts the associated content item to the corresponding associated format.

Abstract: A protective floor film includes a base film layer and a U.V. cured wear layer disposed on the base film layer. The wear layer has a thickness in a range of 2 to 25 micrometers. Methods of making protective floor film and methods of protecting a floor are also disclosed.

Abstract: Protective fluoropolymer layers for dental articles, particularly orthodontic appliances, are provided that reduce adhesion of materials such as food, bacteria, and proteinaceous substances to these surfaces, which can cause staining. Methods of reducing adhesion of these materials to such surfaces are also provided.

Abstract: A fluoropolymer is modified by contacting it with a modifying composition preparable from components comprising a phase transfer catalyst and at least one of a sulfide or disulfide salt, and heating the modifying composition. The modified fluoropolymer is useful in the preparation of composite articles.
