Abstract: Disclosed is a hydrophilic silicone composition comprising an oral care substance. The composition is based on polysiloxanes having a high water-uptake capability. An aqueous solution or dispersion of the oral care substance can be soaked into the polysiloxane, whereby the resulting composition shows favorable release characteristics. The use of hydrophilically modified polysiloxanes, possibly in conjunction with unmodified hydrophobic polysiloxanes, allows for the convenient production of desired shapes, advantageously based on a dental imprint. The hydrophilic modification of the polysiloxane is particularly by including a hydrophilic vinyl monomer, particularly an alpha-olefinic soap, into the composition prior to curing.

Abstract: A laser-based hair cutting device (10) comprises a laser source (18), an optically transparent exit window (15) and optical elements (11, 12, 13, 14). The laser source (18) provides an incident light beam (21) for cutting a hair (22) above and near a skin surface by laser-induced optical breakdown (LIOB) of the hair (22) in a focal position of the light beam (21). The optically transparent exit window has an external exit surface (15) for allowing the incident light beam (21) to leave the device. The optical elements (11, 12, 13, 14) focus the incident light beam (21) in the focal position at a working distance from the exit surface (15).

Abstract: A switchable autostereoscopic display device comprises a display panel having an array of display pixel elements for producing a display, the display pixel elements being arranged in rows and columns. An imaging arrangement directs the output from different pixel elements to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement is electrically switchable between at two 3D modes, wherein the effective position of the imaging arrangement is shifted laterally between the modes with respect to the display pixel elements by an amount which is a non-integer multiple of the pitch between the pixel elements. These two modes enable the resolution per mode to be increased, by adding views at inter-pixel locations, or enables the number of views to be increased.
