Title: Diagnostic test using near infrared laser absorption spectroscopy
Inventor: COOPER DAVID E
IPC: G01N21/39
Filed: 1993-01-13
Abstract: RF modulation spectroscopy of a near infrared laser diode source is used to determine the amount of a target substance in a breath sample. In this type of modulation the laser output is modulated to produce sidebands displaced from the laser carrier by the modulation frequency. The modulated beam is passed through a gas sample which differentially absorbs the sidebands, the result of which is the conversion of some of the laser frequency modulation into amplitude modulation which is subsequently detected using a broadband photodetector. In certain tests, the target substance is a particular isotope, whose concentration is measured as an isotope ratio. In order to measure the presence of first and second isotopic species, provision is made to provide laser illumination at characteristic wavelengths for absorption lines for the first and second isotopic species of the gas. This may sometimes be accomplished using a single laser diode and scanning at least one of its operating parameters in order to achieve one of the wavelength difference. Alternatively, first and second laser diodes operating at the first and second wavelengths are used.

Title: Stockless anchor
Inventor: PETERSEN EDWARD R
IPC: B63B21/44
Filed: 1994-09-23
Abstract: This invention relates to a stockless twin-fluked anchor. The most frequently used anchor on commercial and pleasure boats today is the lightweight or twin-fluked anchor which requires a long stock to ensure that the anchor lies flat on the bottom and both flukes engage the bottom simultaneously. The long stock makes this type of anchor difficult to handle and stowe. In this invention the flukes are shaped so that the anchor will always lie flat on the bottom and both flukes will engage the bottom simultaneously without the need for a stock. In prior art anchors, the crown assembly is attached to the flukes and the stock, and limit the rotation of the flukes relative to the shank, and elevates the aft of the anchor so that the flukes are downward pointing. In this invention the crown assembly is part of the shank, and engaging both flukes simultaneously to limit the rotation of the shank and elevating the aft of the anchor.

Title: Cuvette for automated testing machine
Inventor: MURPHY HAROLD R
IPC: G01N35/00
Filed: 1992-06-09
Abstract: 2137672 9325889 PCTABScor01 A consumable, non-reuseable cuvette (10) for containing a sample or specimen during an automated test thereof, primarily for medical diagnostic purposes. The cuvette has a single, main reaction chamber that is pre-loaded at the factory with the precise quantity of a particular liquid or dry reagent useful for a specific test. The cover (20) of the cuvette includes an opening (26a) to permit the introduction of a diluent or liquid reagent into the reagent chamber, a manually loaded, recessed sample receiving chamber having a frangible bottom floor (36) and a purge reservoir. A  cap (28) is hinged to the cuvette cover and includes a rigid protruding member (34) that pierces the sample or specimen chamber floor when closed by the testing machine, sealing the contents of the cuvette, allowing the sample to be dispensed into the chamber containing the reagent and diluent. The side walls (18) and floor (16) of the reaction chamber include optically transparent windows for radiant energy testing of the reagent before and after the sample is added to the reagent. Because the cap seals the contents of the cuvette, the cuvette is safely disposable after the test is completed.
Patent CA-2143922-A1 (CA)
Title: Electromagnetic actuator designed to exhibit predetermined non-linear characteristics
Inventor: GOLDENBERG ANDREW A
IPC: H02K33/00
Filed: 1995-03-03
Abstract: There is disclosed an electromagnetic actuator designed    to   exhibit    predetermined    non-linear characteristics. The actuator is designed so that as the plunger or rotor moves linearly in the stator,  the gap between the plunger and stator varies in a predetermined manner. Depending on the variation in gap, different force-displacement characteristics are obtained.  A method is provided for determining a given plunger and/or stator pole shape    to   obtain   a   desired    force-displacement characteristic.  The magnetic  field  intensity decreases inherently in response to the changing reluctance due to the varying gap, so that the plunger velocity is reduced non-linearly  to  zero  and  the  plunger  stops  without appreciable overshoot at the desired position. Similarly, the actuator may be accelerated to new positions very rapidly with reduced overshoot/undershoot in very short periods of time typical of industrial applications. The actuator  is  designed  to  be  modular  in  that  various differently shaped plungers may be interchangeably used in the stator.  In such anticipated applications the poles would have a fixed geometry and differently shaped plungers could be used.  With each combination of  the pole and plunger geometry there is a different force-displacement characteristic for the plunger.
