Abstract: Recombinant dendritic cells are made by transforming a stem cell and differentiating the stem cell into a dendritic cell. The resulting dendritic cell is an antigen presenting cell which activates T cells against MHC class I-antigen targets. Kits, assays and therapeutics are based upon the activation of T cells by the recombinant dendritic cell. Cancer, viral infections and parasitic infections are all ameliorated by the recombinant dendritic cells, or corresponding activated T cells. Therapeutic compositions and pharmaceutical compositions are provided.

Abstract: An orthopedic pillow is a monolithic foam structure. Spaced apart depressed top and bottom surfaces are continuous with, and are extensive between the side surfaces. The top and bottom surfaces are each formed as a plurality of side-by-side longitudinal ribs parallel with the long side surfaces. Each one of the ribs protrudes outwardly from the apparatus and is a major portion of a semi-circle in shape. The physical conformation of the apparatus is such, that with the long side surfaces resting on a mattress, the tips of the ribs are initially spaced apart from the mattress, and with a head's weight resting on the top surface, the ribs of the top surface are compressed, and the ribs of the bottom surface are urged toward the mattress providing compressive resistance proportional to the compressive force.

Abstract: A cartridge chip for use with a first type of imaging cartridge and a second type of imaging cartridge comprises a controller and a resistive element connected between the controller and a reference potential, the cartridge chip adapted for operation in a first mode of operation compatible with the first type of imaging cartridge when the controller detects the reference potential through the resistive element, the cartridge chip adapted for operation in a second mode of operation compatible with the second type of imaging cartridge when the controller cannot detect the reference potential through the resistive element.

Abstract: A method of remanufacturing a replaceable consumable unit includes providing the replaceable consumable unit including a first electronic circuit, with the first electronic circuit being at least partially inoperable; providing a second electronic circuit; communicatively connecting the second electronic circuit to the first electronic circuit; and intercepting, by the second electronic circuit, signals sent by an imaging system to the first electronic circuit.

Abstract: A toner cartridge comprises toner and electrical development components which consume a portion of the toner by printing a plurality of images. An electronic circuit stores an indication of the amount of toner remaining, and a value controlling a voltage applied to at least one of the electrical development components. The electronic circuit determines when a predetermined amount of the toner remains in the toner cartridge. When the predetermined amount of toner remains in the toner cartridge, the electronic circuit alters the amount of toner consumed to form images by changing a voltage level applied to at least one of the electrical development components. The electronic circuit alters the amount of toner consumed by replacing the stored value controlling the voltage applied to at least one of the electrical development components with a new value controlling the voltage applied to at least one of the electrical development components.

Abstract: A training system uses a mechanical mock-up with electrically conductive probe points connected to electronically readable memories, and a simulated diagnostic tool to interface with a system or machine simulation for the purpose of operation, maintenance or procedure training. When a probe of a simulated diagnostic tool comes into contact with a probe point of the mechanical mock-up, the electronically readable memory supplies a unique identifier code that is communicated by the simulated diagnostic tool to the simulation to indicate the contact of the probe with the corresponding probe point. Complex wiring connections between the mechanical mock-up and a computer that runs the simulation are eliminated and construction of the training system is significantly simplified.

Abstract: An exhaust gas recirculation valve having a reciprocating pintle shaft supported by a sleeve bushing and having a labyrinthine pathway between a valve operating chamber and a shaft/bushing interface to minimize intrusion of exhaust gases into the interface. The labyrinthine pathway is formed between fixed annular elements of the valve body and shaft bushing and a movable annular element of the valve head telescopically disposed between the fixed elements.

Abstract: An electronic module for use in a printer consumable unit comprises a first input and output (I/O) port adapted connected to an external contact, and a second I/O port connected to the external contact. Circuitry controls the electronic module and responds to read memory commands and write memory commands received through the external contact on the I/O ports. A memory stores data. A third port is connected to the external contact and adapted to source current. The circuitry is initially configured to send and receive data through the first I/O port. The circuitry tests the functionality of the first I/O port by directing the third port to source current and drive the external contact to a predetermined voltage, and read a voltage received by the first I/O port in response to sourced current. If the circuitry determines the first I/O port is not functioning correctly based on the read voltage, the circuitry will send and receive data through the second I/O port.

Abstract: In the toner cartridge recycling and remanufacturing industry, used xerographic products are reconditioned, repaired, and some are refilled with toner. Part of the refurbishment process is the replacing of used and worn components, including an electronic circuit, which has been spent. The electronic circuit is a critical component of the replaceable consumable unit and is used by the printer to store information used in the operation of the printer. Information stored in this electronic circuit relates to how much toner is remaining, the cartridge type, operating characteristics, and so forth. Some of these circuits have been designed for a one-time use application. For example, once the printer has determined that all of the usable toner has been consumed, the printer will essentially turn off the circuit in a replaceable consumable unit and the replaceable consumable unit will no longer function.
