Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.

Abstract: The invention relates to a method and a device for the detection of magnetic particles (1) in a sample chamber (112). After introduction of the sample into said sample chamber (112), the magnetic particles (1) are first retained within the sample chamber (112) and kept away from the sensing surface (111) by an appropriate magnetic field (B) to allow for an incubation of the sample with reagents. A reference measurement may be made during this incubation period (TI), preferably at the end thereof. After incubation, the magnetic particles (1) are allowed to contact the sensing surface (111) where a target measurement can be conducted.

Abstract: A system for providing sensory feedback includes a garment (106) that is configured to flexibly and snuggly fit over a portion of a subject.
