Title: Method and apparatus for managing and monitoring cardiac rhythm using active time as the controlling parameter
Inventor: SPINELLI JULIO C
IPC: A61N1/00
Filed: 1993-03-16
Granted: 2000-05-30
Abstract: A cardiac rhythm management device is described in which the rate controlling parameter of a rate adaptive pacemaker is the heart's total active time. The active time is evaluated using the intraventricular impedance technique, the active time being the length of the interval between the onset of contraction and the point where a line passing through two points on the fast filling segment of the impedance wave form reaches the impedance level corresponding to the end-diastole impedance of the preceding beat.      The approach results in a upper rate limit corresponding to the maximum heart rate that does not compromise circulatory function, e.g., result in a decrease in cardiac output, or an increase in cardiac workload without an associated increase in cardiac output.      The application also teaches the use of the heart's total active time as an indication of hemodynamic instability for triggering a defibrillation.

Patent CA-2112213-C (CA)
Inventor: ROSELIEP ROBERT E
IPC: B23F1/08

Granted: 1995-06-27
Abstract: A blind spline broaching machine for machining splines as well as sprockets, keyways, gears, cams and contours on workpieces, such as shafts. The blind spline broaching machine of the preferred embodiment has dual rams reciprocable relative to a rotary dial.  The rams hold a corresponding pair of workpieces, while the rotary dial supports one or more broaching tools. The rotary dial is rotatable to index the workpieces to and from the rams. The blind spline broaching machine also incorporates a part moving unit on its periphery, which enables the use of a single loading/unloading station at which workpieces are alternately loaded onto and unloaded from the rotary table.  Because the workpieces are loaded and unloaded from the same location on the periphery of the blind spline broaching machine, the side of the blind spline broaching machine opposite the loading/unloading station remains open to permit ready access to the tooling and the interior structure of the blind spline broaching machine.  In addition, only one conveyor system is required to transport workpieces to and from the blind spline broaching machine.  As a result, the complexity of and the floor space required for the blind spline broaching machine is substantially reduced.

Title: Method and apparatus for determining the in situ larmor frequency of a wellbore nmr tool to compensate for accumulation of magnetic material on the magnet housing of the tool
Inventor: FREEDMAN ROBERT
IPC: G01V13/00
Filed: 1994-10-12
Granted: 1999-07-06
Abstract: A system includes a wellbore tool disposed in a wellbore and a surface apparatus disposed at a surface of the wellbore. Prior to operating the tool to take an initial measurement, the wellbore tool is first calibrated to take into account magnetic junk which is magnetically attracted to and accumulated on a magnet housing of the tool. To calibrate the tool, a new tuning frequency, called the Larmor frequency, is determined, and the tool is tuned to the new Larmor frequency before taking an initial measurement. The wellbore tool and the surface apparatus each include a processing system. Each processing system includes a memory. A first part of a tuning frequency determination software is stored in the memory of the tool, and a second part of the tuning frequency determination software is stored in the memory of the surface apparatus. To determine the tuning frequency, the processing system in the wellbore tool initiates execution of the first part of the tuning frequency determination software. Results from this first execution are transmitted uphole to the surface apparatus. The processing system in the surface apparatus then initiates execution of the second part of the tuning frequency determination software. When this second execution is complete, the new tuning frequency, known as the Larmor frequency, is determined. The wellbore tool is then tuned to the new Larmor frequency.

Granted: 2004-03-16
Abstract: A charging system (1) for a variety of batteries (nominal voltage, capacity, chemical components), stepping, and self adjusting to the top-of charge voltage of the battery (12a) by interacting with the terminal  voltage of this battery in each one of a series of periodic intervals (steps). CONTROL means (2) are provided for enabling signals (4) in predetermined subintervals in each periodic interval, to control the charging process. The charging voltage parameter in the running periodic interval is set by REFERENCE VOLTAGE means (10), based on the sample of the terminal voltage of the battery taken by READING means (5) in the beginning of the running periodic interval and slightly amplified by a predetermined factor (25 96). Thereafter VOLTAGE REGULATOR means (15) regulate the voltage of the charging current according to, as this set, charging voltage parameter.  Every time a sample of the terminal voltage of the battery is taken, COMPARATOR means (9) compare this sample with the one taken in the previous periodic interval and, then, the charging is proceeding when this comparison has a predetermined result (or alternately a combination or combinations of results from comparisons of more parameters), otherwise the charging process terminates.

Granted: 2002-11-26
Abstract: A fiber optic transmitter circuit (10) includes a DC bias circuit (12) that produces a DC voltage, an amplifier circuit (U1) having data signal inputs and that produces a data signal and wherein the data signal and the DC voltage are supplied to a laser diode (U2) to stimulate the diode (U2) to produce light of a corresponding nature. The amplifier (U1) is selected so that the inher-ent noise level or noise figure characteristics of the amplifier are such as to provide stimulation of a single mode laser diode in the frequency band wherein the resonant frequency of the laser diode is typically found. The resulting impact of the noise on the laser diode is to transform the single mode laser diode into a multi-mode laser diode thereby reducing the impact of modal noise on the fiber optic data transmission system that incorporates the disclosed fiber optic transmitter device.

Abstract: Multiple piezoelectric ceramic filter elements have different center frequencies from each other and are cascade connected together. The piezoelectric ceramic filter elements satisfy the condition 0 ~dF0~ / BW3 < 0.8; where ~dF0~ is the absolute value of the frequency difference dF0 between the center frequencies, and BW3 is the band width, wherein the amplitude loss is 3dB or less.      Thereby, a low insertion loss and an improvement in the group delay characteristics can be compatible at the same time.

Abstract: Il a été établi que l'allèle HLA B27 est relié à des protéines de bactéries entériques Gram négatif. Les protéines d'organismes entériques qui partagent une séquence avec l'allèle B27 ont tendance à avoir des séquences qui répondent aux motifs structuraux des protéines qui, pense-t-on, prévoient la liaison avec l'allèle B27. Ces séquences (c.-à-d., les peptides) servent pour le diagnostic et la thérapie et peuvent être utilisées pour concevoir d'autres peptides de bactéries entériques Gram négatif qui jouent un rôle important dans les spondyloarthropathies. Ces peptides peuvent servir à détecter des anticorps et des cellules T révélateurs de spondyloarthropathies. Seuls ou en association avec de la microglobuline Beta2 ou des molécules HLA solubles, ils peuvent aussi être utilisés pour produire de la tolérance.
