Abstract: A method for determining whether a particular sample vial has bacterial growth includes the steps of introducing a first light into the sample vial and measuring the intensity of the reemerging light. One then introduces a second light which is different from the first light and has either a different wavelength, or is introduced at a different location than the first light. The reemerging intensity from the second light is also measured. A ratio quantity is calculated based on the two reemerging intensities, and the calculated ratio is compared to expected ratios for both positive and negative samples. It has been found that a comparison of the reemerging light intensities provides a very good indication of whether a particular sample is a positive or negative sample.  Various methods and formulas for calculating the ratios may be utilized.      Graphs associated with the particular methods and formulas are developed experimentally to allow one to compare a particular calculated ratio value to expected values for positive and negative cultures.

Title: Technique for time-sharing a microprocessor between a computer and a modem
Inventor: RAMASWAMY VELRAJ
IPC: G06F13/00
Filed: 1994-12-22
Abstract: A personal computer's microprocessor is time-shared to provide the functions formerly provided by a microprocessor dedicated to a modem. Advantageously, this technique is transparent to software applications programs which interact with a modem. In the disclosed embodiment, the personal computer utilizes an operating system, such as the Microsoft Windows operating system, in which a portion of the operating system, known as the communications driver, provides the interface between the operating system and the personal computer's serial and parallel communication ports. In the disclosed embodiment, all communications between the communications driver and the rest of the operating system are examined. Those communications destined for a particular port associated with a modem not having a dedicated microprocessor are redirected while other communications destined for other ports are passed to the Microsoft Windows communications driver. The redirected communications are coupled to a software application program which utilizes the PC microprocessor to carry out the functions formerly provided by the modem microprocessor. As a result, the modem's microprocessor and associated RAM and ROM can be eliminated. A feature of the present invention is that the software application program can be loaded into the personal computer's memory only when required.

Patent CA-2140715-A1 (CA)
Title: Enhancing bonding design
Inventor: PANTHOFER ROBERT E
IPC: B23K35/26
Filed: 1995-01-20
Abstract: The present invention is an enhanced bonding design utilizing tin and copper to create tin alloy solders for use in the manufacturing of heat exchangers and other soldering applications. The tin alloy solders contain as primary constituent metals 3.0 - 15.0 wt.% copper and 79.0 - 97.0 wt.% tin, and containing as optional constituent metals 0.0 - 4.0 wt.% silver, 0.0 - 1.0 wt.% selenium and 0.0 - 1.0 wt.% bismuth. These solder alloys have lower toxicity levels and better corrosion resistance than the lead based alloy solders commonly employed. Also, because the application temperature range for these solder alloys is below the temperature where dezincification of copper/zinc base metal alloys occurs, joints on copper/zinc base metals subjected to cyclic loads are stronger when constructed using these tin alloy solders than when constructed of lead based alloy solders.

Title: Method for optimizing energy spectrum data from scintillation type radiation detectors
Inventor: PEMPER RICHARD R
IPC: G01V5/04
Filed: 1995-10-05
Abstract: The present invention is a system for analyzing the energy levels of radiation detected by a radiation detector having a multichannel pulse height analyzer. The radiation detector generates signals representative of the energy level of the detected radiation, and the analyzer increments a particular channel dependent on the signal from the detector. The channel incremented by the analyzer is in response to an empirical relationship of the particular channel with respect to energy level. The empirical relationship is determined so that energy spectral peaks occurring over substantially the entire energy detection range of the detector have peak widths spanning substantially equal numbers of analyzer channels. In one embodiment of the invention, the detector is a scintillation counter responsive to gamma ray radiation. In one embodiment of the invention, the empirical relationship is approximated by an ordered expression comprising a third order polynomial function.
