The present invention is a method and apparatus allowing the application of two or more distinct halftone types in the rendering of a single image. The invention employs a halftone selector of a threshold type, or as an alternative a segmenter type. The halftone selector determines which areas of an image will receive which type of grayscale halftone treatment on a pixel by pixel basis. Examples of various halftone types include stochastic, clustered dot, line screen, and other high addressability types. Each pixel of data is treated by the appropriate halftoner circuit which in response outputs digital data. A controller circuit remaps the digital data into the appropriate width and position signals for a pulse width position modulator, including any other signals as needed for any additional inverter circuitry. The pulse width position modulator generates a video signal which may be inverted by the inverter circuit as responsive to the controller circuit remapping determination. This final video signal is provided to an image output terminal.

A projection display system includes a projection lens assembly that has multiple projection lens elements that are configured to receive light imparted with display information by a pixelated display device. The projection lens elements project the light toward a display screen. A pixel-shifting element is included within the projection lens assembly to cyclically shift between at least two positions within the projection lens assembly to form at a display screen at least two interlaced arrays of pixels. An electromechanical transducer is coupled to the pixel-shifting element to impart on it the cyclic shifting between positions.

The present invention provides a method and apparatus for network port and network address translation. Several problems with limited addressability may occur when transmitting data packets between a terminal in a first network and a terminal in a second network that is outside the first network. Data forwarding rules are used to define if and how identifiers of data packets to be forwarded between the two networks correlate with each other. According to embodiments, a data forwarding rule includes a first identifier associated with the first network and a second identifier associated with the second network, wherein each identifier has two parts: a source address and source port number corresponding to a source network node, and a destination address and destination port number corresponding to a destination network node.

In magnetic tape having separate longitudinal servo bands of servo information with superimposed data information, the separate servo bands have selected different superimposed data information, to identify the separate servo bands for independent addressability. The servo information comprises non-parallel laterally extending transitions to indicate lateral positioning, and the selected different superimposed data information may comprise a lack thereof in portion(s) of the servo bands. Where the superimposed data information is longitudinal position information of the tape, the selected different superimposed data information may comprise different longitudinal position information of one or more servo band(s). The selected different superimposed data information may comprise a band identifier in the superimposed data information of one or more of the servo bands.

In the case of printing at high addressability, where the cell size is smaller than the spot size, an image can be decimated in a manner that will limit the large accumulation of printed material. The proper decimation of the image will depend on the spot size, the physics of drop coalescence and the addressability during printing. A simple method of using concentric decimation is disclosed herein to enable this process.

A drop deposition apparatus for laying down a patterned liquid layer on a receiver substrate, for example, a continuous ink jet printer, is disclosed. The liquid deposition apparatus comprises a drop emitter containing a positively pressurized liquid in flow communication with a linear array of nozzles for emitting a plurality of continuous streams of liquid having nominal stream velocity vj0, wherein the plurality of nozzles have effective nozzle diameters D0 and extend in an array direction with an effective nozzle spacing Ly. Resistive heater apparatus is adapted to transfer thermal energy pulses of period τ0 to the liquid in flow communication with the plurality of nozzles sufficient to cause the break-off of the plurality of continuous streams of liquid into a plurality of streams of drops of predetermined nominal drop volume V0. Relative motion apparatus is adapted to move the drop emitter and receiver substrate relative to each other in a process direction at a process velocity S so that individual drops are addressable to the receiver substrate with a process direction addressability, Ap=τ0S. The effective nozzle spacing is less than 85 microns, the process speed S is at least 1 meter / sec and the addressability, Ap, of individual drops at the receiver substrate in the process direction is less than 6 microns. Drop deposition apparatus is disclosed wherein the predetermined volumes of drops include drops of a unit volume, V0, and drops having volumes that are integer multiples of the unit volume, mV0. Further apparatus is adapted to inductively charge at least one drop and to cause electric field deflection of charged drops.

A method and apparatus implementing an enhanced protocol between an I2C master and an I2C slave. In various embodiments the invention permits greater addressability space and high priority access to the slave device. The enhanced protocol is implemented by the addition of command code data being transmitted which is recognized through an interface circuit inside the slave device. The invention provides an I2C solution for accessing high priority address space with one command byte, medium priority space with two command bytes and low priority space with three command bytes.
