A printhead assembly includes an ink distribution assembly including an ink distribution molding, the ink distribution molding including a plurality of first ducts; at least one printhead integrated circuit in fluid communication with the ink distribution assembly; and a rotary platen having at least three surface, each surface for providing one of a platen surface, capping portion, and a blotting portion. The ink distribution assembly further includes a plurality of second ducts acutely angled with respect to the plurality of first ducts, a plurality of transfer ports facilitating fluid communication between the plurality of first ducts and the plurality of second ducts, and a plurality of ink inlet ports facilitating fluid communication between an ink cassette and the plurality of first ducts.

A handheld imaging device includes an image sensor for sensing an image; a processor for processing the sensed image; a plurality of processing units provided in the processor, the plurality of processing units connected in parallel by a crossbar switch to form a multi-core processing unit for the processor; and an image sensor interface for converting signals from the image sensor to a format readable by the plurality of processing units, the image sensor interface sharing a wafer substrate with the processor. A transfer of data from the image sensor interface to the plurality of processing units is conducted entirely on the shared wafer substrate.

A handheld imaging device includes an image sensor for sensing an image: a Very Long Instruction Word (VLIW) processor for processing the sensed image; a plurality of processing units provided in the VLIW processor, the plurality of processing units connected in parallel by a crossbar switch to form a multi-core processing unit for the VLIW processor; and an image sensor interface for receiving signals from the image sensor and converting the signals to a format readable by the VLIW processor, the image sensor interface sharing a wafer substrate with the VLIW processor. A transfer of data from the image sensor interface to the VLIW processor is conducted entirely on the shared wafer substrate.

An inkjet printhead integrated circuit includes: a substrate having a silicon layer; a nozzle plate disposed on the silicon layer; and embedded inkjet nozzle devices. Each inkjet nozzle device includes a nozzle chamber having a roof actuator; drive circuitry laterally disposed relative to the nozzle chamber; a connection arm extending parallel with the nozzle plate from the actuator towards the drive circuitry; and a metal via interconnecting each connection arm and the drive circuitry, the metal via extending perpendicularly to the nozzle plate. The drive circuitry is positioned proximal the nozzle plate relative to a plane of the floor.

A portable handheld device including a CPU for processing a script; a multi-core processor for processing an image; an input buffer for receiving data for processing by the multi-core processor, the input buffer being provided under the control of the multi-core processor to send data thereto; and an output buffer for receiving data processed by the multi-core processor, the output buffer being provided under the control of the multi-core processor to receive data therefrom. The multi-core processor comprises a plurality of micro-coded processing units. The CPU is configured with authority to clear and query the input and output buffers.

A liquid discharge head includes a discharge element substrate and an opening diameter conversion plate. The discharge element substrate and the opening diameter conversion plate are laminated in a first direction. A second opening width is larger than a first opening width in a second direction orthogonal to the first direction. A supply connection flow path configured to connect a first opening and a second opening is formed in the opening diameter conversion plate. A wall surface of the supply connection flow path includes an inclined portion inclining with respect to the first direction.
