  • Patent number: 7346457
    Abstract: A method is provided for evaluating the performance of a plurality of oil wells which were established to produce from a common reservoir beneath the earth's surface. The method comprises inputting information about the reservoir into a computer and establishing a time interval and time steps within that time interval over which performance of the wells will be evaluated. The total oil which is accessible clearing each time step in each time interval is determining, and then individual recovery factor for each time step is determined. A composite recovery factor is determined using the individual recovery factors, and the composite recovery factors are normalized to the best well in the field.

  • Patent number: 7224080
    Abstract: The present invention discloses a subsea power system for use in capturing “free” or “waste” energy (e.g., thermal, geothermal, pressurized subsurface gases or liquids, wind, wave, solar, or other free, waste, or low cost energy sources) to convert and/or store to power a subsea service or device during times when the free or waste energy supply is not as abundant, is not available, or demands require greater output than is provided at steady state. The subsea power system may include: (1) one or more energy-capturing devices—such as a turbine and/or thermoelectric generator—for harvesting free or waste energy, (2) a fuel cell, electrolyzer, and oxygen and hydrogen storage vessels for harvesting energy from the surrounding seawater, and (3) a power converter for receiving energy from the various sources and converting the energy into a useful form consumable by subsea devices.

  • Patent number: 7171313
    Abstract: Apparatus is disclosed for sensing impact events in reciprocating machinery. The apparatus establishes first and second reference or threshold voltages, where the second reference voltage is greater than the first reference voltage. The number of impact events (N1) in a time window that exceed the first reference voltage and the number of impact events (N2) in a time window that exceed the second reference voltage are counted and an output current is generated representative of the number of such impact events. If no impact greater than the lower threshold voltage is received during a given time window, the apparatus detects and stores a peak voltage corresponding to the impact having the greatest magnitude received during that time window. Apparatus according to the present invention produces an output current based on the magnitude of that peak voltage.

  • Patent number: 7141985
    Abstract: An electronics package for use with a proximity probe is disclosed that is capable of being calibrated to work with any proximity probe and cable and that is capable of being programmed in the field. The electronic package establishes and measures a plurality of gaps between the proximity probe and a target. An amplifier is operatively coupled to the proximity probe and produces an output which is digitized, linearized and stored. A linear piecewise approximation technique is used to approximate the voltage at the output of the amplifier for gaps that were not measured.

  • Patent number: 6880703
    Abstract: A floral transport apparatus to facilitate the transportation and delivery of floral arrangements is disclosed. The floral transport apparatus includes a hard plastic container housing a support carriage having a set of longitudinal elastic bands and a set of lateral elastic bands stretched tightly over a box frame to form an upper and lower mesh. The floral arrangement is held securely in the gaps between the tensioned bands of the upper and lower mesh to prevent lateral displacement which would otherwise result in tipping of the floral arrangement. The floral transport apparatus provides a means for carrying many floral arrangements of various sizes simultaneously. Moreover, the floral transport apparatus is easily portable and manageable by a single delivery person and can be washed to keep the apparatus attractive in view of floral customers and potential floral customers.

  • Patent number: 6783516
    Abstract: A trocar is disclosed which comprises a housing assembly having an upper end and a lower end and a cannula assembly attached to the lower end of the housing assembly to define an axial bore therethrough. The disclosed trocar also includes an obturator for sliding engagement in the bore. The housing assembly includes an access port formed on the upper end which is axially aligned with the bore of the trocar. Communication via the access port of the housing is regulated by a flapper valve having a closed position and a range of open positions. The flapper valve comprises a metal flapper door having a male/female configuration formed around the protrusion. In the closed position, the protrusion of the flapper door engages the male/female configuration of both door and port mesh resulting in a metal-to-metal seal across the access port. The metal-to-metal seal provides enhanced resistance to mechanical, heat, and chemical wear encountered during surgical and sterilization operations.

  • Patent number: 6588279
    Abstract: An apparatus for detecting and transmitting impact data is disclosed for use in monitoring early-stage development of harmful mechanical conditions for reciprocating machinery. The impact transmitter device includes a single self-contained unit having a stainless steel housing which contains an impact accelerometer, a detector circuit, a measurement and timing circuit, a 4-20 mA driver circuit, independent polarity circuit, and an electromagnetic impulse protection unit. The impact transmitter device further includes a field adjustable static threshold defining the severity of the impact detected, and a field adjustable reference time window interval. The variable severe impact level threshold allows an operator to isolate severe impacts from typical machine vibration. The variable time window interval allows an operator to synchronize the present invention with different machine speeds and to collect severe impact data over an appropriate time frame.
