Abstract: A radiation detector is disclosed. The detector includes a detector element; a number of electrodes arranged such that an electric field can be applied to the detector element; and a coating.

Abstract: A radiation detector is disclosed. The detector includes a detector element on which electrodes are formed. First and second electrodes are provided at a first surface of the detector element, and are arranged such that, on application of an electric field between the first and second electrodes, a first detector region is formed adjacent the first surface of the detector element. A third electrode is provided on a second surface of the detector element, and is arranged such that, on application of an electric field between the first and third electrodes, a second detection region is formed between the first and second surfaces of the detector element. The first and second detection regions are differently sized for the detection of different types of radiation. Device for detecting radiation, and handheld devices containing such device, are also disclosed.

Abstract: An apparatus to generate a playlist of media created by emerging artists for use by a media distribution center in response to purchasing decisions stored on a website comprises a storage unit configured to receive and store a plurality of media titles from a plurality of emerging artists, an interface for communicating data associated with at least a portion of the stored media titles, and a processor in communication with said storage unit and said interface. The processor is configured to permit a plurality of users to purchase a media title from the emerging artists, record sales data associated with the media titles, generate a playlist of selected media titles in response to parameters associated with the media titles and selected by a media distribution center, wherein at least one of the parameters is related to a the sales data, and transmit data associated with the selected media titles to the interface.
