  • Publication number: 20180319076
    Abstract: A method for 3D printing an object with at least one wall (2) having a first surface and a second, opposite surface, wherein the first surface is intended to serve as an optical functional surface, wherein the wall is formed by printing one track (16) on top of another track (17). An orientation of the object during printing is selected such that the wall has a tangent (or tangent surface) non-parallel to the z-axis, such that the first surface faces away from the x-y plane and the second surface faces the x-y plane. According to the invention, the 3D object is thus oriented during printing such that the first surface, intended to be used as an optical functional surface, faces away from the x-y plane, i.e. typically away from the support or platform on which the 3D object is printed upon. By ensuring this orientation during printing, the first surface becomes smoother than the second, opposite surface of the wall.

  • Patent number: 9618739
    Abstract: An actuator comprises an electroactive polymer layer (402) and stretchable electrode structures (410, 411) that are disposed on each side of the electroactive polymer layer (402). A softer passive layer (401) is secured to one of the stretchable electrode structures (410, 411). When compressed transversally by the stretchable electrode structures (410, 411), the electroactive polymer layer (402) will expand tangentially and the actuator will relax into a shape wherein the interior of the electroded region is substantially parallel to the plane of the device, while a substantial portion of the area increase is absorbed by out-of-plane bends arising at the electrode boundary (duck mode). The invention can be embodied as optically reflective or refractive devices with variable geometry.

  • Patent number: 8337031
    Abstract: The invention relates to a color-tunable illumination system (10), to a lamp and to a luminaire. The color-tunable illumination system comprises a light source (20) emitting light of a first predefined color (B), and comprises a luminescent material (30) for converting light of the first predefined color into light of a second predefined color (A). The color-tunable illumination system further comprises shielding means (40, 42) arranged for preventing at least part of the light emitted by the light source to impinge on the luminescent material. The light source, the luminescent material and/or the shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color.

  • Patent number: 7925056
    Abstract: A method for investigating and ascertaining pulse or heartbeat includes directing illuminating radiation to illuminate a body part such as a finger. The illuminating radiation is of a wavelength or wavelength band substantially in the blue light region of the light spectrum. Then, an optical speckle pattern of the illuminated body part resulting from the illumination of the body part is obtained and imaged. The optical speckle pattern is representative of the heartbeat and by correlation of frames extracted from the speckle pattern, the pulse or beat extent of the body part may be ascertained.
