Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector system—e.g. over time—for continuous image improvement are also disclosed.

Method for providing a container with food, the method comprising: providing a container for infant formula food, adding the food, sealing the container with a gas-tight membrane seal, adding an inner scannable code on the gas-tight membrane seal, closing the container with a tamper-proof closure means, so that the inner scannable code is not scannable without breaking a part of the tamper-proof closure means, and storing the inner scannable code in a database.

A packaging apparatus for small piece goods, the use of the packaging apparatus, and a method for producing a blister tube are provided. The packaging apparatus includes a packaging material guiding device for providing a shaped packaging material web suitable for receiving small piece goods, a longitudinal joining device which is arranged downstream of the packaging material guiding device and a transverse joining device which is arranged downstream of the packaging material guiding device. The transverse joining device joins the shaped packaging material web together at predetermined intervals transversely to the direction of travel to form a transverse joining area. The transverse joining device includes two joiners, which have a plurality of embossers that are individually movable transversely to the direction of travel and have an embosser stop area which cooperate such that elevations that are palpable are formed by the embossers in the transverse joining area.

A system and process of printing a package of expanded material (e.g., expanded starch, foam or other expanded material). The expanded material can be heated and extruded, poured, sprayed, or otherwise applied in malleable form that sets up to become a porous protective covering for an item to be packaged. In an example, a layer of expanded material is laid down, and the item in a protective covering (e.g., a plastic bag, sleeve, coating, etc.) is positioned on the layer of expanded material. Additional layers or expanded material may be applied, thereby encasing the item. The top surface of the expanded material may be flattened, such as by operation of a roller, press, or cutter. The top surface may be sprayed with a shellac sealant, paint, or other coating, to allow printing of a label on the top surface.
