Abstract: A method for easily identifying optical lines without error irrespective of the lengths of the lines. A plurality of reflective parts are provided as an identification mark on each optical line. The combination of the correlative positions of the plural reflective parts of an optical line is different from others. The correlative positions of the reflective parts of a line are determined on the basis of the reflected light of the inspecting light incident upon the optical line. According to the results of the determination, the optical line is identified. Mare specifically, when inspecting light is incident on the end. of an optical line, the light is reflected by the plural reflective parts which function as an identification mark, and is caused to return to the incident end. Since the combinations of the correlative positions of the reflective parts are different from each other, the correlative positions of the plural reflective parts of an optical line are found by measuring the differences between the lengths of the optical paths of the optical lines from the reflective parts by use of an interferometer or by measuring the differences in the times for the reflected light to return from the reflective parts.      The optical lines can be identified on the basis of the results of such measurement.

Title: Navigation receiver with coupled signal-tracking channels
Inventor: SENNOTT JAMES W
IPC: G01S19/11
Filed: 1993-05-03
Granted: 1996-04-09
Abstract: The navigation receiver with coupled-tracking channels is intended for use in radio navigation systems based on trilatera-tion wherein the times of arrival of radio signals transmitted by a plurality of ground- or space-based terminals are measured by a user terminal and utilized by the user terminal in calculating its position and orientation. The coupled-tracking navigation re-ceiver periodically measures carrier phase, carrier frequency, modulation phase, and carrier amplitude for all of the signals arriving at the receiving ports of the receiver and periodically es-timates the present values of carrier phase, carrier frequency, and modulation phase for all of the received signals, the estimat-ing process utilizing for each parameter estimate the parameter measurements for a plurality of the received signals properly combined in a statistically appropriate manner by taking into ac-count the relative geometry of the line-of-sight paths, receiver clock time dynamics, and dynamics and motion constraints of the receiver platform, thereby obtaining better performance un-der poor signal reception conditions and more accurate esti-mates of carrier phase, carrier frequency, and modulation phase for each of the received signals than independent measurements alone could provide. It follows that these more accurate esti-mates of the basic signal parameters lead to more accurate esti-mates of platform position and attitude and the rates of change of these quantities.

Abstract: Methods and apparatus for eliminating the effects of electrosurgical interference on continuous, heat-based cardiac output measurements employing several procedures, including the steps of (1) supplying power via an isolation transformer (12) and carrier frequency to a catheter-mounted heating element (16); (2) measuring the voltage and current on the primary side (10) of the isolation transformer (12); (3) determining the voltage and current on the secondary side (14) of the transformer (12) on the basis of the measured primary side voltage and current; and (4) calculating the power delivered to and resistance of the catheter- mounted heater (16) on the basis of the secondary voltage and current. A heater power waveform generated with this process will be substantially free of electrical interference due to electrosurgical devices. Then, a system transfer function may be produced via signal processing techniques which involve cross-correlating the heater powe r waveform with the blood temperature waveform. The system transfer function will be uncorrupted, even if the blood temperature waveform contains moderate electrical interference, since the heater power waveform is free of any correlated electrical interference.

Title: Delivery catheter for electrolytically detachable implant
Inventor: MILLS TIMOTHY
IPC: A61B17/12
Filed: 1996-04-26
Granted: 2001-04-03
Abstract: The invention involves a catheter for introducing a delivery member such as a guidewire having an implant coupled thereto via an electrolytically disintegratable link that is coupled to the anode of a power supply having an anode and a cathode. The catheter comprises an elongated tubular member having an outer surface, proximal and distal end portions, a lumen extending between those portions, an electrode and a conductor. The electrode is disposed within the outer surface of the tubular member in the vicinity of the distal end portion and has a surface that faces and communicates with the lumen. The electrode is electrically coupled to the conductor which, in turn, is adapted for coupling to the power supply cathode such that when the electrolytically disintegratable link is placed in an ionic solution, such as can be found in an aneurysm, and positive current is provided from the power supply to the link, current from the link may return to the cathode of the power supply via the electrode. With this construction, the electrode is shielded from endolumenal structures which could otherwise increase the resistance in the current path from the sacrificial link to the electrode. The positioning of the electrode in the catheter as described above allows a reproducible impedance path from the electrode to the detachment zone, thus reducing detachment time variability.
