Abstract: Electronic systems, such as printing systems, often use components that have a memory. The integral memory can be used to store information about the component. In some printing systems this memory includes storing a portion that stores a value indicative of an amount of a consumable that has been used. Discloses is a method and system for updating a memory that is integral to a component within a printing system. The value stored in the memory can be read to determine an amount of a consumable used. Alternatively, when a specific value is stored in the memory the printing system can deactivate the component.

Abstract: Many devices, such as printers, work with one or more removable unit. Often, the removable units have an electronic circuit that used to communicate with the device. It may be desirable to provide a replacement unit in these devices. The replacement unit must include an electronic circuit that is able to communicate with the original device. Disclosed is a method and apparatus where a replacement unit is provided with a new electronic circuit and a used electronic circuit. The new electronic circuit is electrically connected to the used electronic circuit and uses the used electronic circuit to facilitate communication with the host device.

Abstract: A flow control element comprises a cylindrical element body having a bore formed therethrough. The cylindrical element body may include inner and outer peripheral surfaces and define a plurality of tortuous flow passages which extend between the inner and outer peripheral surfaces. The flow control element is formed as a unitary structure wherein the flow passages are oriented along at least two axes. The flow control may be formed by direct to metal laser sintering wherein successive layers of powdered metallic material are solidified by applying laser energy to the selected portions until the flow element is formed as a unitary structure with a plurality of flow passages extending therethrough. The laser energy is selectively applied to the powdered metallic material according to a computer model of the flow control element.

Abstract: A universal OPC drum that allows a remanufacturer to stock a minimum number of OPC drum sleeves of various sizes and then add the appropriate gear for the desired cartridge at the time of cartridge remanufacture. A universal OPC drum may also include a universal hub and an electrical contact on each end to maintain universality without regard to whether the OEM contact is mounted on the drive or non-drive side of the OPC drum.

Abstract: In accordance with the present invention, there is provided a valve assembly wherein a heating modality such as an induction heater is cooperatively engaged to a prescribed location on a valve housing or body of a valve to effectively maintain the temperature of the valve above the saturation temperature of the related system pressure. Maintaining this temperature differential effectively avoids the accumulation of condensate within the interior of the valve body and/or on other internal structural features thereof.

Abstract: A ROM circuit includes a first N channel transistor having an output and having device geometry and device characteristics adapted to bias the output at a predetermined level when a P channel circuit is connected to the first N channel transistor; a pass transistor connected between the output and a data bus, the pass transistor connected to a word line, the word line adapted to turn ON the pass transistor when the word line is asserted; and the P channel circuit connected to the data bus and adapted to provide leakage current to charge a gate in the first N channel transistor when pass transistor is turned ON.

Abstract: A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and three prongs extending longitudinally outward from the end surface.

Abstract: Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of a print yield. Disclosed is a method and system for allowing the memory to have data indicative of an increased print yield.

Abstract: Techniques for modifying an imaging cartridge includes providing the imaging cartridge comprising a body including a circuit holding structure sized to hold an electronic circuit and forming a modified circuit holding structure, with the modified circuit holding structure sized to hold a replacement electronic circuit. At least one dimension of the replacement electronic circuit may be greater than a corresponding dimension of the electronic circuit.

Abstract: An improved spray nozzle assembly for use in a steam desuperheating device that is adapted to spray cooling water into a flow of superheated steam. The nozzle assembly is of simple construction with relatively few components, and thus requires a minimal amount of maintenance. In addition, the nozzle assembly is specifically configured to, among other things, prevent thermal shock to prescribed internal structural components thereof, to prevent “sticking” of a valve element thereof, and to create a substantially uniformly distributed spray of cooling water for spraying into a flow of superheated steam in order to reduce the temperature of the steam.

Abstract: Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of an amount of a consumable that has been used. Some printing systems do this by using a counter to count the amount of the consumable used and then sending a count command to the memory. The increment count command is processed to increment the value stored within the memory. Disclosed is a method and system for allowing the memory to be updated by a count command without having to increment the value stored. This method allows print cartridges to be used in printing systems that utilize counters without having to increment the counter each time an increment command is received.

Abstract: In accordance with the present invention, there is provided a bi-directional shut-off trim for a valve which possesses the functional attributes of a pilot operated trim and a balanced trim through the integration of a spring loaded check valve into a pilot trim. In forward flow isolation, the bi-directional shut-off trim of the present invention acts as a normal pilot operated trim. In reverse flow, the check valve of the shut-off trim opens to balance the pressure on either side of the plug thereof.

Abstract: Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes a drive gear to transmit rotational force from the printer to the print cartridge. Also, it is desirable to remanufacture print cartridge both to reduce waste and to save resources. Therefore, it may be desirable to provide a drive gear mechanism that is easily replaced or reused when a print cartridge is remanufactured.
