Abstract: A printer controller for supplying dot data to at least one printhead module and at least partially compensating for errors in ink dot placement by at least one of a plurality of nozzles on the printhead module due to erroneous rotational displacement of the printhead module relative to a carrier, the printer being configured to: access a correction factor associated with the at least one printhead module; determine an order in which at least some of the dot data is supplied to at least one of the at least one printhead modules, the order being determined at least partly on the basis of the correction factor, thereby to at least partially compensate for the rotational displacement; and supply the dot data to the printhead module.

Abstract: A printhead comprising: a first and second elongate printhead modules, the printhead modules being disposed end to end on either side of a join region, wherein the first printhead module and the second printhead module are vertically offset at the join region; and, at least first and second printer controllers configured to receive print data and process the print data to output dot data for the printhead. The first printer controller outputs dot data to both the first printhead module and the second controller; and the second printer controller outputs dot data to the second printhead module, wherein the dot data output by the second printer controller includes dot data generated by the second printer controller and at least some of the dot data received from the first printer controller.

Abstract: Weld-free connections and connectors and methods of forming such connections and connectors are provided wherein first and second members are positioned so as to create a joint region and a cavity, and wherein the cavity is filled with a polymeric material that adheres to at least the joint region to form a weld-free connection or connector once the polymeric material has cured.

Abstract: A mechanism for providing assistance in opening the cover of an access hatch having a frame wherein the cover is pivotally mounted to the frame. The mechanism includes a spring mounted in a housing having a large diameter tube and a small diameter tube, with the smaller tube being attached to the cover. The tubes interact in a telescoping fashion. The mechanism is mounted to the frame by a slotted hanging bracket.

Abstract: The present invention relates to an image processor (242) comprising a control register block (1470), a decoding block (1468), a data object processor (1462), and flow control logic. The control register block (1470) stores all the relevant information about the image processing operation. The decoding block (1468) decodes the information into configuration signals, which configure an input data object interface (1460). The input data object interface (1460) accepts and stores data objects from outside, and distributes these data objects to the data object processor (1462). For some image processing operations, the input data object interface (1460) may also generate addresses for data objects, so that the source of these data objects can provide the correct data objects. The data object processor (1462) performs arithmetic operations on the data objects received. The flow control logic controls the flow of data objects within the data object processing logic (1462).

Abstract: A timepiece includes a rotatable bezel mounted on the housing. A storage area inside the housing contains a plurality of folded or crumpled sector elements. The sector elements each have an apex which is attached to a curved spring-like wire and a base which is attached to the housing. Rotating the bezel causes detents in the bezel to push the wires out of the storage area and causes the wires and the sector elements to cover a conventional solid dial face which is mounted in the housing thereby changing the appearance of the dial face. The sector members may have various indicia formed thereon.

Abstract: The invention provides an encryption circuit for encrypting and decrypting data as it travels to and from a hard disk. The encryption circuit can be turned on or off under control of the BIOS program and a user supplied password. With the present invention, a removed hard disk cannot be read without the user supplied password and a similar encryption circuit.

Abstract: An apparatus and a method for performing discrete cosine transformation (DCT) are presented. The apparatus includes an arithmetic circuit interconnected with a transpose memory. The arithmetic circuit includes a combinatorial circuit for calculating a DCT without using an intermediate clocked storage unit. The combinatorial circuit includes a predetermined number of sequentially arranged stages for implementing the DCT. The apparatus may optionally include a controller for controlling operation of the apparatus and a multiplexer for multiplexing data input to the apparatus and data from the transpose memory. An apparatus and a method for performing inverse discrete cosine transformation (IDCT) are also presented.

Abstract: A color display system that is capable of taking input intended to be displayed on a full color display (e.g. VDU) having a high refresh rate and displaying the image on a display having a much reduced number of displayable colors and a lower refresh rate. 24-bit RGB data is input and converted into bi-level RGBW data and halftoned in a render unit for storage before display. Motion detection is used to ensure that only those pixels that have change in value are updated on the display.

Abstract: Display standards in common use for the display of computer or television images on high resolution displays, commonly assume that the output image will be displayed on an output device having a high refresh rate. A high refresh rate is normally required so the viewer does not observe flicker, stilted motion or other visual artifacts if a lower refresh rate were used. It is difficult to drive some displays at a high refresh rate. An apparatus is disclosed for detecting areas of an input image that are changing over time, even where the input image may be subject to some degree of noise. A priority value is determined for providing a measure of this change for use with a system to determine which areas of the image may need changing as a matter of high priority.
