Patent number: 8047709Abstract: A method and system for detecting the location of an air/sea interface on an Instrumented Tow Cable (ITC) when distributed temperature measurements are provided. The air/sea interface is determined by estimating the variance of observed temperature in the proximity of each measurement cell. The method and system described herein uses a sliding variance across the entire cable length. The variance of the cell or cells in the area of the interface has been found to be large compared to other cells. Accordingly, the location of the air/sea interface is determined based on the location of the peak variance. The location of the air/sea interface is used in determining the catenary of the ITC.Type: GrantFiled: March 27, 2009Date of Patent: November 1, 2011Assignee: The United States of America as represented by the Secretary of the NavyInventor: Mark J.

Patent number: 4692063Abstract: A tractor provided with a cable reel at one end and a plow at the trailing end includes a system to monitor tension applied to the cable during underground placement. A capstan engages the cable while driven by a hyraulic motor and the pressure of the fluid supply to the motor is monitored by a pressure transducer. An electrical signal from the pressure transducer is fed to a control which also receives a setpoint signal corresponding to a maximum allowable tension on the cable. An output signal from the control is used to slow down or stop advancing movement of the vehicle and a second signal is used to operate a valve to divert fluid pressure from the hydraulic motor. Tension on the cable extending between the capstan and the reel can be monitored as well as tension on the cable between the capstan and the plow.Type: GrantFiled: November 1, 1985Date of Patent: September 8, 1987Assignee: Arnco CorporationInventor: Allen C.
