  • Patent number: 10084342
    Abstract: A power receiver device including: a pair of receiver electrodes (341, 342) for capacitively coupling with the pair of transmitter electrodes (321, 322) placed on one side of a surface; and a deformable transfer layer (371, 372) placed between each of the pair of the receiver electrodes and another side of the surface. A power signal generated by the power driver (110) is wirelessly transferred from the pair of transmitter electrodes (321, 322) to the pair of receiver electrodes (341, 342) to power a load (150) in the power receiver device.

  • Publication number: 20160349524
    Abstract: A multi-view display device comprises a pixelated display panel and a backlight comprising an arrangement of light sources (30), wherein each light source, when turned on, illuminates an associated region of pixels of the display panel. A display controller is adapted to control the pixelated display panel and the arrangement of light sources such that a partial display output is provided comprising simultaneously a set of at least three 2D views with no repetition of individual 2D views. This arrangement provides an output with controlled illumination direction of the pixels so that view repetitions are avoided. The output can be a single cone of views, and the location from which the cone of views can be viewed depends on the relationship between the light sources of the backlight which are activated and the display panel.

  • Patent number: 8807816
    Abstract: A luminaire (20) comprising a light guide (11) having a first refractive index (n1), the light guide (11) comprising a light-entry surface (14), a light-reflecting surface (15) for reflecting light entering at the light-entry surface (14), and a light-exit surface (16) opposite the light-reflecting surface (15), for allowing light to exit from the light guide (11), the light guide (11) being tapered toward the opposite end relative the light-entry surface (14).

  • Patent number: 8570645
    Abstract: A beam steering device (300) for deflecting a beam of light is provided. The beam steering device comprises a first deflecting member (310), a rotating member (320), and a second deflecting member (330). For an incoming beam of light having components (303, 302) with their polarization parallel (303?) and perpendicular (302?), respectively, to an optic axis (314, 334) of the beam steering device, the parallel component (303) is deflected by a first angle (304) when passing the first deflecting member. When passing the rotating member, the polarization (303?, 302?) of the beam of light is rotated by 90 degrees (303?, 302?). When passing the second deflecting member, the perpendicular component (302) is deflected by a second angle (305).

  • Publication number: 20130176727
    Abstract: The invention relates to an optical module comprising two or more segments positioned around an axis of symmetry of the module. Each segment includes a light collimating structure for providing a predefined light distribution of light exiting the module and a light source assembled in a cavity within the light collimating structure. The center of the cavity coincides with the optical axis of the light collimating structure and is at a distance (d) from the axis of symmetry of the module. Including two or more segments where each segment comprises its own light source allows obtaining higher lumen output compared to prior art luminaires having only one light source while arranging the segments so that the center of each cavity coincides with the optical axis of the collimating structure of the segment allows preserving narrow beamwidth collimation of the light exiting the module.
