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.

The present invention is directed to a process for manufacturing a pack of products (1) having a bottom side (2) and an opposite top side (3), comprising a handle (5) formed over the top side (3) and adapted to be grasped by hand, wherein the process comprises the following steps:—providing the products (1) to be packaged;—fitting a binding structure around the products (1) to bind them;—forming a handle (5) by wrapping a plastic film (4) around the bound products (1) over at least one turn, the plastic film (4) covering at least most of the bottom side (2) and being gathered to a reduced width over the top side (3) to form the handle (5). The present invention is also directed to a device for manufacturing a pack of products (1).

The innovation disclosed herein is an improved palletiser for loading and packaging unstable articles, such as plastic, glass, steel, aluminium, etc. containers onto a pallet for bulk storage and/or transport. The innovation includes a pallet station having a pallet housing that receives pallets, a layer pad store substantially aligned with the pallet housing, a container lifting sub-assembly that receives a predetermined row of containers, a pusher assembly that urges the predetermined row of containers onto a pallet, and a layer pad transfer assembly.

Control of a wrapping apparatus is facilitated by enabling an operator to input a load containment force requirement and/or a minimum number of layers of packaging material to be applied to a load, with a wrap control system automatically determining wrap force and other parameters required to meet user input requirements and/or parameters to minimize the expertise required of an operator and to provide more consistent and reliable wrapping of loads. In addition, a wrapping apparatus may be controlled to apply at least a minimum number of layers of packaging material to a load throughout a contiguous region thereof.

A method for packaging masonry products, comprising stacking the masonry product. Wrapping the masonry product with a packaging film from a first position to a second position below a top of the product. Placing a top sheet on the top of the masonry product, the top sheet forming at least one vent assembly. Wrapping the masonry product and the top sheet with the packaging film below the vent assembly.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.
