摘要： A method and device for sensing spatial variations and/or temperature variations in the locality of a fibre optic cable 1 is disclosed, wherein a broadband light source 47 is used to shine incident light onto a series of fibre Bragg gratings contained within zones A, B and C. Each zone contains a plurality of fibre Bragg gratings, the plurality of fibre Bragg gratings in any one zone having a substantially identical grating period, and the fibre Bragg gratings in the respective zones having different grating periods. The reflected light from each fibre Bragg grating is returned back down the fibre optic cable 1 and redirected via a 2×1 coupler 51 to a wavelength detection system 53 and a personal computer 63. The combination of wavelength detection system 53 and personal computer 63 allow analysis of the reflected light patterns, as well as providing a user interface which enables detection of the occurrence of a spatial and/or a temperature variation. The location of the said variation along the fibre optic cable 1 is advantageously detectable in terms of the particular zone A, B or C in which the said variation has been sensed.

摘要： The methods and systems for efficiently transferring images from an image bearing member include placing an overlayer over a toner layer after placing the toner layer over the image bearing member. The overlayer reduces the adhesiveness of the toner layer to the image bearing member and, therefore, promotes efficient transfer to another substrate without applying heat. The overlayer also may have a higher cohesiveness and combine with the toner layer to increase the effective cohesiveness of the toner image to increase the efficiency of the transfer of the toner image. Overlayer materials include, by way of non-limiting example, a clear toner layer or a clear fluid layer.

摘要： An apparatus and method develops an electrostatic latent image directly from an imaging member to a final substrate, such as paper or the like. An image development apparatus and method creates a first electrostatic latent image on an imaging member and deposits a toner layer on the imaging member. The image developer then generates a second electrostatic latent image in the toner layer in response to the first electrostatic latent image on the imaging member. The second electrostatic latent image can be generated by either a broad source ion charging device or an air breakdown charging device. Next, the latent image bearing toner layer is selectively separated and developed such that the image areas are developed directly from the imaging member onto a final substrate and the non-image areas remain on the imaging member.

摘要： A novel image development method and apparatus are disclosed, whereby image-wise charging of a toner layer is accomplished by induce air breakdown electrical discharge such that free mobile ions are introduced in the vicinity of an electrostatic latent image coated with a layer of developing material. The latent image causes the free mobile ions to flow in an image-wise ion stream corresponding to the latent image, which, in turn, leads to image-wise charging of the toner layer, such that the toner layer itself becomes the latent image carrier. The latent image carrying toner layer is subsequently developed and transferred to a copy substrate to produce an output document.
