Abstract:
A printhead is provided having an assembly of printhead modules. Each printhead module has a support defining fluid chambers, a fluid distributor on the support, and an integrated circuit on the distributor so that fluid in the chambers is distributed to the fluid ejection nozzles of the integrated circuit by the distributor. The support and distributor of each printhead module are shaped to define complementary formations on opposite sides of that printhead module so that the printhead modules are mated together in an angled fashion with the integrated circuits of the mated printhead modules abutting together and diagonally overlapping to define at least one row of fluid ejection nozzles of the printhead.
Abstract:
A printhead module assembly includes a printhead integrated circuit (IC) assembly having a plurality of ink ejection nozzles arranged to form staggered rows, and defining a plurality of ink channels for supplying ink to the ink ejection nozzles; a flexible printed circuit board (PCB) electrically connected to supply both power and data to the IC assembly; a support sheet defining a plurality of ink holes and to which the IC assembly is bonded so that the ink channels are aligned with the ink holes; and a channel layer mounted to the support sheet adjacent to the IC assembly, the channel layer defining a plurality of slots aligned with respective air holes defined in the support sheet.
Abstract:
A cradle unit for a printhead cartridge is provided having a support bay for removably receiving the printhead cartridge, and an interface mounted on a slanted face within the support bay, the interface comprising connections which are movably tilted on said slanted face so as to be exposed within the support bay for connection with connections of the printhead cartridge when received in the support bay. The connections of the interface connect the printhead cartridge with a power supply which is remote from the interface.
Abstract:
A portable handheld device includes an image sensor for capturing an image; and a one-chip microcontroller having integrated therein a CPU for processing a script language and a multi-core processor for processing an image captured by the image sensor. The multi-core processor includes therein multiple processing units connected in parallel by a crossbar switch. Each processing unit includes an arithmetic and logic unit (ALU). Each ALU includes a first register set for accepting data from the first crossbar switch, and a second register set for loading data to the crossbar switch.
Abstract:
A method of displaying hyperlinked information using a handheld display device. The method includes the steps of: imaging an area of a printed substrate and generating image data using an image sensor; determining interaction data using the image data; retrieving display data using an identified page description, the display data including a hyperlink associated with the printed content; displaying, on an opaque touch-sensitive display screen of the handheld display device, display information based on the display data and including the hyperlink; interacting with the displayed hyperlink; retrieving hyperlinked information; and displaying the hyperlinked information. The opaque touch-sensitive display screen has real-time virtual transparency through the screen to the printed content from a user's perspective to provide a virtual window to the printed content.
Abstract:
A portable hand-held device is provided having components housed in a body. The components include a power supply, an image sensor for sensing images of a scene, a flash unit for illuminating the scene, a network interface for sharing images between the device and a network, and an integrated circuit processor.
