摘要： An ink-jet printhead accepts a series of digital addresses as image data. Each digital address causes an individual ejector in the printhead having the particular address to be activated. The frequency of operation of the printhead can be directly related to the frequency at which addresses are submitted to the printhead. A scheduler polls image data for spot placements which require simultaneous activation of a plurality of ejectors in a set of interdependent ejectors, and then reschedules the activation of ejectors to avoid conflicts.

摘要： The invention describes a temperature sensing system which provides a digital signal representative of the temperature of an ink jet printhead during a predetermined time period. In one embodiment, a temperature controlled oscillator is formed on the printhead, the oscillator including a resistor whose resistance varies proportional to printhead temperature variations. An analog signal from the resistor representative of printhead temperature is converted by the oscillator into a digital output signal whose frequency varies with variations in the resistor and, therefore, with the printhead temperature. The oscillator outputs are counted in an electrical counter over a sampling period. The accumulated count is converted into a digital code representing the printhead temperature. This byte is available for comparison with predetermined values stored in a look-up table and is converted into electrical image signals sent to the printhead which are adjusted and compensate for changes in the volume of ink ejected by the printhead nozzles. In a preferred embodiment, the oscillator counter and synchronizing circuitry are formed on one chip located on the printhead. The printhead can be either a single partial width printhead located on a carriage which is moved through a print zone or a full width printhead. The temperature sensing circuit has a high signal to noise ratio resulting in a more accurate temperature measurement. Because of the noise immunity, the sensing can take place during a print operation.

摘要： A method and apparatus for controlling the volume of ink droplets ejected from printhead nozzles over a larger printhead operating temperature range. Each nucleating electrical pulse applied to the heating elements in the printhead to eject an ink droplet is preceded by a plurality of non-nucleating pre-pulses. Based upon the printhead temperature sensed, a controller selects the pre-pulse width and time width between pre-pulses from a look-up table.

摘要： The present invention provides a fuel efficient membrane electrode assembly that substantially resists methanol from “crossing over” by sealing the anode diffusion layer and catalyst layer, and by preventing fluids from passing across at least a portion of the membrane electrolyte. The efficiency of the fuel cell is maintained because essentially all of the fuel is reacted on the catalyst layers creating electricity, which is transferred to the fuel cell load. The temperature of the fuel cell is also maintained as the uncatalyzed reaction that produces heat is prevented.

摘要： A simplified direct oxidation fuel cell system is provided. The fuel cell is constructed in such a manner that fuel is added to the cell anode as it is consumed and water is evaporated off at cell cathode so that there is no need for recirculation of unreacted fuel at the cell anode or water at the cell cathode. In addition, carbon dioxide generated from the anodic reaction is passively vented out of the system by using a CO2 gas permeable membrane material integrated as part of the anode chamber construction. Other embodiments of the invention include a fuel container and delivery assembly.
