  • Patent number: 8025383
    Abstract: A printhead for an inkjet printer that has a printhead integrated circuit with nozzles for ejecting ink, and a support structure for supporting the printhead IC. The support structure has ink conduits for supplying the nozzles with ink and a fluidic damper containing gas for compression by pressure pulses in the ink within the ink conduits to dissipate the pressure pulse. Damping pressure pulses using gas compression can be achieved with small volumes of gas. This preserves a compact design while avoiding any nozzle flooding from transient spikes in the ink pressure.

  • Patent number: 8020965
    Abstract: A printhead for an inkjet printer is disclosed. The printhead has one or more a printhead integrated circuits (ICs) with an array of nozzles for ejecting ink. A support structure of the printhead supports the printhead ICs. The support structure has ink conduits for supplying the array of nozzles with ink. Each ink conduit includes cavities distributed along a roof of the ink conduit. An opening to each respective cavity has an upstream edge and a downstream edge. The upstream edge contacts the ink before the downstream edge during initial priming of the ink conduits from an ink supply. The upstream edge has a transition face between the ink conduit and the cavity interior. The transition face is configured to inhibit ink from filling the cavity by capillary action during initial priming of the ink conduit. This causes gas to be trapped within the cavity. The gas acts to compress pressure pulses in the ink.

  • Patent number: 7957359
    Abstract: A scheme is provided for allocating spectral resource made up of a plurality of resource units in a multiple access wireless link linking a partition of a base station and at least one child user equipment of the partition in a wireless communications network. According to the scheme the same fixed allocation of resource units is made to each user equipment of the network. According to one embodiment a measure of a maximum likely number of child user equipments per partition of the network is determined. Then a fixed allocation of resource units based on the ratio of the number of resource units per unit time to the measure is calculated. Then the same fixed allocation of resource units is allocated to each child user equipment across the network. In one embodiment resource units which are not allocated in the fixed allocation remain unallocated to user equipments.

  • Patent number: 7942500
    Abstract: A printhead is provided for an inkjet printer that has a print engine controller for receiving print data and sending it to the printhead. The printhead has a printhead IC for ejecting ink and a support structure for mounting the printhead IC in the printer adjacent a paper path. The printhead IC is mounted on a face of the support structure that, in use, faces the paper path. A flexible printed circuit board (flex PCB) that has contacts for receiving print data mounted to the support structure on a face that does not face the paper path. The bent section reduces the likelihood of trace cracking by holding the flex PCB at a set radius rather than allowing the flex to follow an irregular curve and thereby risking localized points of high stress on the traces.

  • Patent number: 7837297
    Abstract: A printhead for an inkjet printer that has a printhead integrated circuit (68) with nozzles for ejecting ink and a support structure (64, 174, 176) for supporting the printhead IC. The support structure having ink conduits (182) for supplying the array of nozzles. A plurality of cavities (200), each cavity having an opening that establishes fluid communication with the ink conduits, the openings being configured such that the cavities do not prime with ink when the ink conduits are primed from the ink supply. By leaving unprimed cavities throughout the support structure, any pressure pulses in the ink are damped by compression of the trapped gas pockets. Distributing the cavities rather than using one relatively large cavity, means that the pressure pulse is being damped along the length of the printhead IC, instead of allowing the pulse to travel the length of the ink conduit until it reaches the single damper and compresses the gas.

  • Publication number: 20100277559
    Abstract: An inkjet printer that has a filter with a chamber divided into an upstream section and a downstream section by a filter membrane. An inlet conduit establishes fluid communication between an ink supply and the upstream section. An outlet conduit establishes fluid communication between the downstream section and a printhead. During use at least part of the inlet conduit is elevated relative to the filter membrane. By elevating the inlet conduit relative to the filter membrane, it acts as a bubble trap to retain bubbles that would otherwise obstruct the filter. This allows the filter size to be reduced for a more compact overall design.

  • Patent number: 7819507
    Abstract: A printhead for an inkjet printer that has a printhead integrated circuit (IC) with an array of nozzles for ejecting ink, and a support structure for mounting the printhead IC within the printer. The support structure has ink conduits for supplying the array of nozzles with ink, the ink conduits have a meniscus anchor for pinning part of an advancing meniscus of ink to divert the advancing meniscus from a path the advancing meniscus would otherwise take. If a printhead consistently fails to prime correctly because a meniscus pins at one or more points, then the advancing meniscus can be directed so that the advancing meniscus does not contact these critical points. Deliberately incorporating a discontinuity into an ink conduit immediately upstream of the problem area can temporarily pin to the meniscus and skew the meniscus to one side of the conduit and away from the undesirable pinning point.

  • Publication number: 20100225092
    Abstract: A hitch-and-coupler assembly (130) couples a trailer vehicle to a towing vehicle. The hitch-and-coupler assembly (130) includes a hitch assembly (132) having a pitch hinge part (134) that defines at least one pinhole towards its trailing end about a pitch hinge axis (138). The hitch-and-coupler assembly also includes a coupler assembly (140) having a pitch hinge counterpart (142) defining at least one pinhole (144) towards its leading end. The pitch hinge counterpart (142) is detachably connectible to the pitch hinge part (134) by positioning the pitch hinge counterpart (142) into a check position in which the pin holes (136, 144) are aligned for passing a pitch hinge pin (26) there through. The hitch-and-coupler assembly (130) also includes a guiding arrangement (146) having a guiding surface (148) extending away from the check position toward a leading end of the hitch assembly (132).

  • Patent number: 7780278
    Abstract: An ink coupling for connecting an inkjet printer and a replaceable cartridge configured to not drip ink upon detachment. The coupling has a cartridge valve on the cartridge side of the coupling and a printer conduit on the printer side of the coupling. The cartridge valve and the printer conduit having complementary formations configured to form a coupling seal when brought into engagement. The cartridge valve is biased closed and configured to open when brought into engagement with the printer conduit. Upon disengagement, the coupling seal breaks after the cartridge valve closes, and an ink meniscus forms and recedes from the complementary formations as they separate, the cartridge valve having external surfaces configured so that the meniscus travels across the external surfaces and only pins itself to the printer conduit surfaces.
