Title: Optical fiber splice verification system
Inventor: DEVEAU GEORGE FRANK JR
IPC: G02B6/38
Filed: 1993-08-25
Granted: 1997-03-25
Abstract: The splice verification system (10) of the present invention verifies the efficiency of an optical splice by measuring the scattered light escaping from the splice. Specifically, the preferred embodiment performs such scattered light measurement within a photodetection area which is substantially free of all ambient light. Furthermore, the verification system includes a reference power module (12) which, prior to creating an optical splice, measures the level of the optical signal being transmitted out of the end of an active fiber. The present invention then provides means to correlate the level gauged as a reference signal level relative to the amount of scattered light lost from the optical splice. The ratio of these two measured light levels may then be used to determine whether the amount of scattered light lost from the optical splice is acceptable given the particular constraints of the optical system in which the splice is employed.

Filed: 1993-09-08
Granted: 2005-01-25
Abstract: An apparatus for dynamically balancing a combined assembly of a drive shaft and axle input shaft for use in a vehicle drive train system. The apparatus includes a drive head adapted to be connected to one end of the drive shaft and a support head for supporting the axle. The support head includes a cradle plate extending upwardly from a base plate mounted on the apparatus. The cradle plate has an arcuate recess formed in the upper surface thereof which is adapted to receive and support a housing of the axle. A pair of support arms are also secured to the base plate, extending upwardly and outwardly therefrom. The support arms are adapted to be secured outwardly extending portions of the housing of the axle. The apparatus further includes first and second intermediate heads which are adapted to engage and support other portions of the drive train system. Sensors are provided on each of the heads for generating electrical signals which are representative of the amount of vibrations induced when the components of the drive train system are rotatably driven by the drive head.      As a result, the combined assembly of the drive shaft and the axle input shaft can be dynamically balanced for use in the vehicle.

Abstract: A lighting fixture for use in hazardous locations and adverse environments, includes a mounting plate and a first ballast housing.  A second non-interchangeable ballast housing may be alternately employed by use of an adapter ring removably securable intermediate the mounting plate and the second ballast housing.  The adapter ring comprises a top portion specially adapted to engage the mounting plate, with  first fastening means associated therewith,  and a bottom  portion  specially  adapted  to  engage  the  second ballast  housing,   with  second  fastening  means  being associated  therewith.    The  adapter ring  allows  the replacement of the first ballast housing with the second, wherein the  first  and  second ballast housings  are  not identical and are produced by different manufacturers.  The adaptor ring effectively seals the  interfaces with the mounting  plate  and  second  ballast  housing,   thereby maintaining the integrity of the lighting fixture for its intended purpose.

Abstract: An   implantable   atrial   defibrillator   provides cardioverting electrical energy to the atria of a patient's heart in need of cardioversion and a pre-cardioversion warning to the patient.  The atrial defibrillator includes a detector for detecting atrial activity of the patient's heart, and an atrial fibrillation detector responsive to the atrial activity detector for determining when the atria of the patient's heart are in need of cardioversion.   A cardioverter  responsive  to  the  atrial  fibrillation detector, applies warning electrical energy to the atria of the  patient's  heart  when  the  atria  are  in  need  of cardioversion   and   thereafter   applies   cardioverting electrical energy to the atria.   The warning electrical energy  is  of  insufficient  quantity  to  intentionally cardiovert the atria but of sufficient quantity so as to be discernable by the patient.

Abstract: A conformable, self-aligning, high extraction efficiency coffee filter pack (1) capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk coffee and a paper filter under identical brewing conditions, but which exhibits substantially consistent pot-to-pot brew strength for any given automatic drip coffee maker. The preferred filter pack (1) is formed from two layers of flexible material (10, 20) which are secured to one another about their outermost periphery with a predetermined quantity of roast and ground coffee (50) housed within a brew chamber (40) formed between the two layers (10, 20). The brew chamber (40) exhibits a maximum volume between about 25 percent and about 300 percent greater than the volume of the dry roast and ground coffee (50) contained therein. The discharge flow rate from the brew chamber (40) is slower than the inlet flow rate into the brew chamber (40) to permit a buildup of water and flooding of the brew chamber (40). The flexible conformable sidewall (25) surrounding the brew chamber (40) extends upwardly a vertical distance which is at least sufficient to capture enough hot water to totally immerse the brew chamber (40) when the brew chamber (40) is in its fully expanded condition. This causes the roast and ground coffee (50) within the chamber to expand and float throughout the remaining portions of the brew cycle, thereby establishing a steady state brewing condition which is highly effective in maximizing coffee/water contact as the hot water passes through the brew chamber (40) on its way to the pot.

Abstract: A fabric (50) comprises a multiplicity of yarn-like fiber bundles (51), which extend between and are interconnected at junctures (52). These fiber bundles and junctures define a pattern of openings (53) with the openings having a generally square configuration. Each of the fiber bundles comprises fiber segments which have been densified and compacted, In these fiber bundles many of the fiber segments are parallel to each other. As may be seen in the drawing, substantially at the center of the fiber bundle between adjacent junctures, there is a further entangled area (54) wherein the fibers tend to be circumferentially wrapped about the periphery of the parallel compacted fiber segments. As may be seen, the fiber bundle projects, from the opposite sides of the circumferentially entangled area. This configuration is hereinafter referred to as a "bow tie" or "bow tie area".

Abstract: A method for calculating a coagulation characteristic of a sample (513) of blood, a blood fraction, or a control comprises generating an output signal (501) indicative of coagulation of the sample, sampling the output signal (501) at a sampling rate for a predetermined time to provide a plurality of sample signal values, storing (500) the sampled signal values, rectifying (604) the stored sampled signal values to provide a plurality of envelope values (503), and storing (606) the envelope values (503). The stored envelope values (503) are examined in reverse time order to determine a slope of the envelope (503) at each of the stored envelope values (503). All relative maximum is in the stored envelope values (503) are identified. A range of stored envelope values (503) corresponding to each relative maximum is determined.  The identified relative maxima are compared (732, 734, 736, 738) to locate an absolute maximum in the stored envelope values (503). The coagulation characteristic is then calculated from the stored envelope values within the predetermined range of envelope values corresponding to the absolute maximum.
