  • Patent number: 7216696
    Abstract: A heat exchanger is mounted external to a section of flue pipe or is an integral part of a section of flue pipe. The heat exchanger preheats a domestic hot water supply and boosts the return water temperature prior to reentry to the furnace coil. The heat exchanger reduces fuel use, pollution and wear of the furnace and burner. A typical heat exchanger installation includes an oil or gas burner located on a furnace or boiler having a flue pipe leading to a gaseous outlet, such as a masonry chimney. A short vertical flue section leads to a draft-regulating damper. The flue heat exchanger may be a coil of tubing wrapped around flue section, such that the tubing picks up heat from the heated flue gasses. Preheated water exits from the heat exchanger.

  • Patent number: 7207804
    Abstract: A multi-media method and system performs psychological assessment of an individual for suitability for particular jobs, whereby the individual is shown and provided with discrete visual and auditory stimuli on a multi-media computer screen, so that the individual's responses can be monitored in conjunction with physiological responses received by biofeedback sensors. The computer tallies the test subject's recorded responses. Virtual work environments are optionally displayed, to enable the tested individual to simulate a real work environment. Unlike other job evaluation systems, the system evaluates a job candidate's ability to maintain task focus under pressure. It directly measures performance under pressure, rather than only inferring potential performance based upon selective input from a job candidate.
