Abstract: A shaving razor has a housing joined to a handle, one or more blades mounted in the housing and a light source. The light source projects a defined image indicating the exact location of a blade edge on the skin of a user enabling the user to properly align the blade edge on the skin during shaving.

Abstract: An optical system is disclosed for use in sorting apparatus to monitor light at a viewing station thereof to generate signals indicative of the optical properties of selected items in the product stream being sorted. In the system light received from a single line at the viewing station is split into discrete beams, which are filtered into different wavelength ranges to determine the category of the respective product items. The beams are directed onto a slit through which the light beams must pass on their way to respective lines of light sensors.

Abstract: A laser beam emitted from a stripe-shaped area of a laser diode is expanded in its low divergence axis to match a length of a modulator which individually modulates different regions of the beam to produce a plurality of individually modulated beam portions which are focused by a lens onto a recording medium, such as dye and receiver sheets, to effect data recording. The modulator may be a row of LCD cells, an acousto-optic modulator, or a row of micromirrors.

Abstract: A fibre laser (2) is used in data-recordal, such as dye diffusion thermal transfer printing. The fibre laser output (3) is modulated and scanned across a recording medium (4) of adjacent dye donor and receiver ribbons by a modulator (20) and galvanometer (16), so that an image is produced line-by-line in the medium (4) as it passes between spools (19). The fibre laser (2) may comprise a single-mode, neodymium-doped lasing core (5), a multimode pump core (6), an outer cladding (7), and a dichroic mirror (8) at each end, and may be pumped by beams (10) from laser diodes (9) coupled to the pump core (6) by optical fibres (11) and a lens (14). Instead of using a galvanometer (16), the output end of the fibre laser (2) may be moved itself across the recording medium (4), and/or a plurality of the fibre lasers (2) may be bundled together in a one or two dimensional array.

Abstract: Printing methods and apparatus for thermal transferring dye from a dye donor to a dye receiver wherein electromagnetic radiation such as a laser beam is applied through the dye receiver to effect dye transfer. Either or both of the dye donor and the dye receiver used with such printing methods and apparatus can be in the form of individual sheets or continuous ribbons and may be either stationary or moving. In various embodiments, the dye receiver is held between a convex surface of a rigid support plate and the dye donor during thermal transfer of dye. A variety of methods and devices for providing electromagnetic radiation and for transporting dye donors and dye receivers during printing are also disclosed.
