Abstract: A multilayer article is configured to provide cushioning for a musical instrument. The multilayer article has an attachment layer configured to be detachably coupled to the musical instrument. An upper raised section layer is attached to the attachment layer and configured to be concave downward. A lower raised section layer attached to the attachment layer and configured to be concave upward. A center raised section layer attached to the attachment layer between the upper raised section layer and the lower raised section layer. The upper raised section layer, the lower raised section layer and the center raised section layer are arranged to ergonomically accommodate a clavicle of a human user.

Abstract: A photovoltaic device including a composite down-converting layer disposed on the device, is presented. The composite down-converting layer includes down-converting material particles dispersed in a matrix. The size of the down-converting material particles is a function of a difference in respective refractive indices (?n) of the down-converting material and the matrix such that: (i) for ?n less than about 0.05, the size of down-converting material particles is in a range from about 0.5 micron to about 10 microns, and (ii) for ?n at least about 0.05, the size of down-converting material particles is in a range from about 1 nanometer to about 500. A photovoltaic module having a plurality of such photovoltaic devices is also presented.

The down-converting layer have a graded refractive index, wherein a value of refractive index at a first surface of the down-converting layer varies from a value of refractive index at a second surface of the layer. A photovoltaic module having a plurality of such photovoltaic devices is also presented.

Abstract: In one aspect of the present invention, a photovoltaic device having a down-converting layer is presented. The device includes a glass plate having a first surface and a second surface. The first surface is exposed to ambient radiation. A transparent conductive layer is disposed adjacent to the second surface of the glass plate. The device further includes a first type semiconductor layer disposed adjacent to the transparent conductive layer and a second type semiconductor layer disposed adjacent to the first type semiconductor layer. The down-converting layer is interposed between the second surface of the glass plate and the transparent conducting layer. The down-converting layer exhibits an effective refractive index that has a value between the respective refractive indices of the glass plate and the transparent conductive layer. A photovoltaic module having a plurality of such photovoltaic devices is also presented.

Abstract: The base of a security/prevention system is an electronic device which has the capability of joining the performance of two functions, i.e. prevention of road accidents and theft protection of vehicles, using the principle of joint use of frequencies, whereby interference with the device's operation is prevented. The invention allows, on the one hand, such application in road traffic prevention in which an electronic security device installed in a vehicle provides passive or active warning of participants in the traffic as to possible momentary dangers requiring quick reaction of the driver. On the other hand, the invention allows such application in road traffic safety in which an electronic security device protects vehicles against theft; the device comprises three base units, i.e.
