摘要： An apparatus and method compensates for a voltage drop of electrical pulse signals selectively applied to a plurality of heater elements on a printhead of an ink jet printing device. A number of heater elements to be pulsed at a given time is determined and a time duration of each of the pulse signals is selected based on information including the determined number of heater elements to be pulsed. In another aspect, the position on the printhead of the heater elements to be pulsed is determined and the time duration of the pulse signals is selected further based on the determined position. By varying the time duration of the pulse signals applied to the heater elements, a voltage drop across the heater elements due to the number of heater elements simultaneously pulsed and/or the position of the heater elements on the printhead is compensated for, maintaining reliable jetting performance while minimizing the voltage by which operating printing voltage needs to exceed the threshold printing voltage.

摘要： A fuel container and delivery apparatus is provided which also allows for removal of effluents from the fuel cell. The fuel container and delivery assembly includes an inner flexible bladder containing fuel for a liquid feed fuel cell. The fuel container and delivery assembly is fitted with a pressure-applying element that exerts a continuous pressure upon the fuel-containing flexible bladder in such a manner that the fuel is expressed through a conduit in the container to the direct oxidation fuel cell. The fuel is supplied to the fuel cell in a continuous manner, or on demand. The fuel container may be a replaceable cartridge. In accordance with one embodiment of the invention, the assembly includes a second bladder that is provided to receive effluent from the fuel cell which may be comprised of carbon dioxide and unreacted fuel and water from the anode side, or of water from the cathode side, or a combination of both.

摘要： The present invention provides a gel fuel, which includes a fuel substance held in a polymeric structure. One embodiment of the composition includes neat methanol, to which a thickening substance, such as that sold commercially under the trade name Carbopol®, is added to impart viscosity, as well as stabilizing and suspending properties. In addition to the thickening substance, a further substance can be added to balance the pH of the gel fuel when needed. In accordance with the invention, a fuel cell cartridge is provided that has at least one aspect that is methanol-permeable, and which may include a fuel vapor permeable layer and it may be comprised of one of a number of various alternative materials. Features within the fuel cartridge can be used to increase surface area of the gel fuel, and to maintain the gel fuel in a desired location within the cartridge.

摘要： An improved fuel delivery system and fuel cell system is provided which includes a component, which delivers fuel from the fuel cartridge by connecting with a corresponding component in the anode chamber of the fuel cell. Liquid fuel is transported into the anode area via an action in which fuel is drawn through the material which may be substantially comprised of a foam-based substance. Gases, including carbon dioxide, that are produced in the anodic reaction can be removed because the foam is gas permeable. Electrons produced in the reaction are collected by a wire mesh that lies between the foam and the membrane electron assembly. The flow of fuel between the foam and the fuel cartridge and the foam and the anode can be interrupted by breaking the connection between the cartridge and the cell, or the cartridge can be pulled away from the fuel cell to break the connection between the foam components. The invention may be employed with a fuel cell stack, or with an enclosed, refillable fuel cell system. The cathode side of the fuel cell may also have a foam component to draw water away from the membrane electrode assembly while allowing oxygen to come in contact with the membrane.

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： An ink jet printer has a temperature sensor as a permanent part thereof. The temperature sensor is mounted on the translatable carriage of the printer. A replaceable printhead cartridge having a printhead bonded to a heat sink is installed on the translatable carriage. Once the printhead cartridge is installed on the translatable carriage, the temperature sensor is placed into intimate contact with printhead'heat sink, so that the temperature sensor moves with the printhead and provides continual temperature measurement.

摘要： A method and apparatus for maintaining a print quality of an ink jet apparatus comprises selecting one of a plurality of different pulse signals to apply to at least one heating element. The heating element is energized with the selected pulse signal. An actual voltage drop is then measured across the heating element. The actual voltage drop is subsequently compared with a desired voltage drop. Then, a new pulse signal is selected to energize the heating element based on the results of the comparison. The repetitive process continues until the actual voltage drop is substantially equal to the desired voltage drop. In another embodiment, a bubble sensor is used to determine whether a bubble has been formed over the heating element.
