Abstract: Systems and methods are disclosed for air flow optimization. In certain embodiments, the technology is a system comprising sensors, injectors, actuators, and a system processor. In order to optimize the air flow, the system processor directs the injectors to expel aerosol particles into an environment, such that the aerosol particles can be measured by the one or more sensors. Flow intensity map generation is then used to map the aerosol particles and air flow is changed to optimize aerosol particle concentration using the actuators.

Abstract: A vacuum cleaner comprises a housing and a motor fan assembly arranged to generate an air flow. A detachable dirt container is mountable to the housing and the dirt container has a dirty air inlet in fluid communication with the motor fan assembly. A filter is for separating dirt from the air flow and the filter is mounted between the dirt container and the motor fan assembly. Wherein the detachable dirt container comprises an emptying aperture in a wall of the dirt container, the emptying aperture being downstream in the air flow from the dirty air inlet and upstream of the filter. Wherein the housing comprises an overlap portion for covering the emptying aperture in the dirt container and sealing the emptying aperture when the detachable dirt container is mounted to the housing.

Abstract: A disposable cartridge for use in a hemodialysis machine has a blood flow path for carrying a volume of blood to be treated in a dialyser and a dialysate flow path, isolated from the blood flow path, for delivering a flow of dialysate solution through the dialyser. The cartridge is received in an engine section of the machine. The engine section has first and second platens which close when the cartridge is inserted to retain the cartridge. Actuators and sensors arranged on the second platen control operation of the cartridge.

Abstract: A banked purification system having, in flow series, an inlet for entry of a fluid, a bank of two or more purification columns in which the fluid is purified by a purifying component, and an outlet for discharging the purified fluid, the columns being arranged in parallel such that the fluid from the inlet splits at first ends of the columns into respective streams which flow through the columns and recombine at second ends of the columns for onward travel to the outlet; wherein the columns have first ports in the side walls of the columns at the first ends, the first ports being connected to each other such that the first ends are placed in fluid communication to create a manifold from the first ends of the columns which splits the fluid from the inlet into said streams.

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.
