Title: Fiber optic gyro with damped gel suspended coil mounting
Inventor: DYOTT RICHARD B
IPC: G02B6/00
Filed: 1994-12-22
Abstract: The sensing coil of a fiber optic gyroscope is wholly or partially surrounded by a gel. The components attached to the coil, such as the directional coupler(s) and polarizer, may also be wholly or partially submerged in the gel. The gel is contained by a rigid housing, in which the inner walls of the housing form a cavity for the coil and the gel. The cavity is filled with the gel, and the gel may be bonded to the inner walls of the housing. The gel remains stiff enough to maintain the coil in a fixed position relative to the housing, and soft enough to avoid any significant effect on the h of the coil over the operating temperature range. Furthermore, the gel can be loaded with particles to adjust the specific gravity of the gel, to modify the thermal properties of the gel and to increase the viscosity of the gel for improved vibration damping. In a modified form, the optical-fiber sensing coil is positioned on a mounting surface and otherwise surrounded by the gel. Alternatively, the opticalfiber sensing coil is wound around a form that has a layer of gel on the coil-supporting surface.

Patent CA-2161500-A1 (CA)
Inventor: TABANOU JACQUES
IPC: G01R27/22
Filed: 1995-10-26
Abstract: A logging apparatus is adapted to be disposed in a mud filled wellbore, and a measurement probe is connected to a bottom of a tool string of the logging apparatus. The measurement probe is adapted for measuring a resistivity of a mud in the mud filled wellbore. The measurement probe includes a bottom electrode disposed on a bottom of the probe when the logging apparatus is disposed in the wellbore, a second electrode, and at least one measurement electrode disposed adjacent the bottom electrode for measuring a voltage potential drop in a region of the mud which is disposed directly below the bottom electrode of the measurement probe when the probe is disposed in the wellbore. When the measurement probe is energized, a current flows in the mud between the bottom electrode and the second electrode. When the current is initially emitted into the mud from the bottom electrode, and when the current is received from the mud in the bottom electrode, the current flows in a direction which is approximately parallel to a longitudinal axis of the logging apparatus tool string. Since the measurement electrode is disposed adjacent the bottom electrode, the measurement electrode measures the voltage potential drop in a region of the mud disposed directly below the bottom electrode. In addition, the voltage potential drop in such region measured by the measurement electrode is controlled primarily by the current being emitted from or received in the bottom electrode and flowing in such region.
