  • Publication number: 20080060602
    Abstract: An engine assembly including a piston for rectilinear reciprocation within a cylinder. Rectilinear reciprocation of the piston allows for a sealing off of a fuel chamber such that fuel may be maintained and delivered to a combustion chamber independent of any lubrication oil to be employed at the interface of the piston and an inner wall of the cylinder. Additionally, the piston may be considered self-lubricating or monolithic in nature due to the presence of passageways for transferring engine fluids therethrough.

  • Publication number: 20080060612
    Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

  • Publication number: 20080060615
    Abstract: A method for controlling spark timing in an internal combustion engine. The method includes determining, in response to a knock sensor mounted to the engine, a spark offset to the scheduled spark timing for the engine at relatively low engine speed which is applied to the scheduled spark timing at relatively high engine speeds. This offset is applied in conjunction with a time-varying spark retardation bias. The offset is removed at a rate proportional to the time varying spark retard bias. The bias increases if either a relatively large torque is demanded from the engine or the engine is at the relatively high speed and relatively high air charge condition; otherwise, the bias is decreased with time.

  • Publication number: 20080060621
    Abstract: A fuel injector for heating fuel to be injected into an internal combustion engine. A cylindrical barrel extends between a solenoid and an injection tip for passage of fuel. The outer surface of the barrel supports a suitable circuit pattern formed of an electrically resistive material for generating heat which is passed through the wall of the barrel to warm the fuel which may be stationary or flowing. The electrically resistive material has a positive thermal coefficient, permitting voltage to be applied continuously across the heater causing a current to flow through the heater, the current being inversely proportional to the temperature of the heater. Thus, the heater is self-regulating, the current automatically increasing under cold conditions and diminishing as the fuel injector warms up after starting of the engine. Desirably, the heater is outside both the engine firing chamber and the flow path of the fuel.

  • Publication number: 20080060644
    Abstract: The need for the delivery of insulin by injection can be reduced or eliminated by delivering aerosolized insulin. Repeatability of dosing is obtainable by using either regular human insulin or monomeric or analog insulin. When delivering insulin (not monomeric) by inhalation, the total inhaled volume should be about the same at each delivery to obtain repeatable results, preferably a high volume is used, but a consistent low volume can be used as well. The patient can be coached by teaching to inhale a given amount of air and can also be coached by teaching to inhale at a given flow rate. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. A dry powder or a liquid insulin formulation is delivered to the patient from a mechanical or electronic hand-held, self-contained device.

  • Publication number: 20080060646
    Abstract: A method of operating a ventilator assembly having inhalation and exhalation passages communicating with one another, and a respiration assembly that can perform repetitive respiratory cycles. The method includes (a) connecting the conduit with an open end of an endotracheal tube positioned within the trachea so that the open end leads into the airway below the vocal cords, (b) repetitively cycling the respiration assembly so that during the inhalation phase, gas in the inhalation passage flows through the endotracheal tube and into the airway, and during the exhalation phase, an exhalation valve is maintained relatively closed and the exhaled gases flow pass the vocal cords and out of the mouth thereby facilitating the patient's ability to speak, and (c) monitoring ring the pressure within at least one of the passages during both phases for determining the pressure within the patient for use in operating the ventilator assembly.

    Abstract: An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

    Abstract: A patient interface is described which is reduces the pressure of the mask on the users face. The patient interface has a sealing interface having an inner sealing member and an outer sealing member. The inner and outer sealing members are adapted to seal around the facial contours of a user providing a sealed fluid communication to the user's respiratory tract. The inner and outer sealing members are at least continuously in contact with each other around the portions where the sealing interface contacts the users facial contours. The inner sealing member may be provided with cut outs to provide additional flexibility to particular areas, such as the nasal bridge, upper lip or cheek regions and may be provided with a contoured edge to better fit the facial contours of a user.
