  • Patent number: 5284118
    Abstract: A fuel injection control system for a two cycle crankcase compression internal combustion engine wherein two sensors are provided for sensing air flow by measuring different engine running conditions. One sensor has a greater accuracy in a certain range of operation than the other and the system primarily sets the fuel injection based upon the output of the more sensitive sensor for the running condition. In the event of failure of the more sensitive sensor, the system defaults to control by the other sensor. The system bases the control on average readings over a number of cycles and also senses fault by determining when a sensor outputs a number of erroneous signals that are greater than a predetermined percentage.

  • Patent number: 5284121
    Abstract: An internal combustion engine has an evaporated fuel purge system for directly feeding evaporated fuel of a fuel tank into an intake pipe of the engine during the engine is running. This system comprises a purge control valve for opening or closing a flow line which connects an upper space of the fuel tank with the intake pipe, a controller for controlling the operation of the valve, a throttle section formed in series with the purge control valve, and pressure and temperature sensors which are located on the upstream side of the throttle section for detecting a pressure and a temperature of the evaporated fuel. When a value detected by the pressure sensor exceeds a predetermined value of pressure for providing a critical pressure ratio at which a flow rate of the evaporated fuel at the throttle section substantially equals to a sonic velocity, the controller opens the purge control valve to cause a purged flow of the evaporated fuel whose flow rate is constant.

  • Patent number: 5284122
    Abstract: An internal combustion engine has a carburetor for mixing fuel with air entering through an inlet. A heat exchanger is mounted onto the carburetor air inlet so that heat from the heat exchanger is conducted to the carburetor housing. The heat exchanger has a plurality of channels through which air from an air cleaner pass on the way to the carburetor. An electric heating device attached to said heat exchanger and a first thermostat controls the electric heating device to raise the temperature of the heat exchanger when the fuel-air mixture falls below a given temperature. A second thermostat senses the temperature of the heat exchanger and prevents the temperature from exceeding a level at which a user's skin will blister if the exchanger is touched accidentally. In cold operating environments, the heat exchanger assembly raises the temperature of the air above the dew point, thus effectively lowering the relative humidity.

  • Patent number: 5284123
    Abstract: A pressure wave supercharger includes a fixed cellular member having an array of parallel longitudinal cells. A segmented impeller fan at a first open end of the cells alternates the cells from being in fluid communication with a supply of fresh air and being in communication with an intake manifold of an internal combustion engine. At the opposite open end of the cells, a segmented turbine fan alternates the cells from being in communication with a supply of exhaust gases and being in communication with a path to the atmosphere. The walls of the cells are coated with a catalytic material, so that the cellular member acts as a catalytic converter substrate. The collision of the exhaust gas with fresh air within the cells and the sonic and positive-pressure pulses compress the fresh air while reversing its direction of flow, whereafter the air is channeled to the engine. The exhaust gases are likewise reversed in direction, expanded, reduced in noise and toxins, and then released into the atmosphere.

  • Patent number: 5284139
    Abstract: A method for converting a value for the partial pressure of oxygen (pO.sub.2) in blood at a measurement temperature to a corresponding value at a reference temperature (37.degree. C.). A value for pO.sub.2 is determined by measurements made in a patient's blood stream using a phosphorescent compound that is sensitive to the concentration of oxygen. The phosphorescent compound is illuminated with a short pulse of light, causing it to produce a phosphorescent emission having a rate of decay that varies as the function of the partial pressure of oxygen in the blood surrounding the phosphorescent compound. A detector produces an electrical signal corresponding to the intensity of the phosphorescent emission, and the electrical signal is converted to a corresponding digital value for input to a microcomputer. Also supplied to the microcomputer in digital form is a signal indicative of the temperature at the measurement site where the phosphorescent compound is disposed.

  • Patent number: 5284151
    Abstract: An electrocardiograph system which enables safe data transfer with high reliability between a portable electrocardiograph and a recorder, such as a printer, and in which an effect of leakage magnetism is taken into consideration. In the electrocardiograph system, electrical signals and/or electric power are transferred between the electrocardiograph and the recorder by electro-magnetic coupling therebetween using independent coils. The electrocardiograph system is further provided with a device for rejecting noise of an electric power signal from the electrical signals or noise of an electrical power signal and a clock signal from a data signal.

  • Patent number: 5284152
    Abstract: A computer controls a video display having a display screen for displaying ECG heartbeats superimposed over one another. The ECG data is collected during Holter monitoring and stored in a memory. A plurality of successive heartbeats are written to the display with their R-waves aligned. As the next new heartbeat in chronological order is displayed the longest-displayed heartbeat is removed. The total number of heartbeats displayed therefore remains constant. The user can select the total number of heartbeats, between one and five, to be displayed at one time. In one mode, a heartbeat is added, and removed, during each screen refresh cycle. In another mode, the user can step the display in either reverse or forward chronological order one step at a time.

    Abstract: A novel medical device, SNOPPER--The Snoring Stopper.TM. anti-snoring mouth device, is inserted into the mouth. The device comprises a denture-like(10) apparatus for supporting electrodes(12) in such a manner that the electrodes make contact with the roof of the mouth. Electrical stimulation induces contraction of relaxed muscles, thereby preventing or stopping snoring. Electrical energy is provided to the device via wires for connection to an external stimulator(16) or via a self-contained, battery-powered, microminiturized electronic stimulator(20). Stimulation can be constant or intermittent. Wave shape, amplitutde, length, and frequency is controlled by the individual for comfort and is automatically induced via a feedback mechanism.

    Abstract: A surgical instrument assembly and method particularly for grasping and displacing a large tubular organ such as a colonic section during a laparoscopic procedure comprises an elongate rigid tubular member, an elongate rod having at least a portion slidably inserted in the tubular member, and two or four prongs connected to the rod at a distal end thereof. The prongs each have an arcuate configuration when ejected from a distal end of the tubular member by a distally directed motion of the rod. Upon ejection, the prongs form a substantially C-shaped clamping member with a pair of grasping jaws. The prongs are flattened out and pressed towards one another when the distal end of the tubular member is shifted over a proximal portion of the prongs.

  • Patent number: 5284164
    Abstract: The present invention comprises a method for improving the quality of products produced in a cigarette manufacturing process. Selected machine operating parameters for at least one machine are monitored, as well as the product being produced. Samples of the product being produced are automatically obtained and tested for quality parameters. Machine operators are notified when to manually test samples of the product for quality parameters. The machine operators can request a test of a quality parameter. The actual test measurements of the quality parameters for either the automatically obtained samples or the manually tested samples are compared against expected values and alarms are presented and the testing is resequenced when the measured quality parameters fail to meet the expected values. Also, employee solution procedures are presented to aid in problem resolution. The time periods and downtime reason when each machine is inoperative is recorded.
