Title: Method for attenuating low frequency noise in a dual-sensor seismic streamer
Inventor: TURNBULL NEIL
IPC: G01V1/38
Filed: 2009-05-06
Abstract: A calculated vertical velocity sensor signal is determined from a recorded pressure sensor signal (11). A constructed vertical velocity sensor signal is determined as a linear combination of the calculated vertical velocity sensor signal and a recorded vertical velocity sensor signal in dual-sensor seismic streamer data, using a mixture coefficient as a proportionality constant (12). An upgoing pressure wavefield component is determined as one half of a difference of the recorded pressure sensor signal and the constructed vertical velocity sensor signal, as a function of the mixture coefficient (13). An error in the upgoing pressure wavefield component is determined by propagating errors in the recorded pressure sensor signal and constructed vertical velocity sensor signal terms (14). A value of the mixture coefficient is determined that minimizes the error in the upgoing pressure wavefield component (15).

Patent CA-2745585-A1 (CA)
Inventor: MACINTYRE JAMES A
IPC: A63B69/16
Filed: 2011-07-06
Abstract: A device relating to simultaneously controlling both the steering and balance of a two-wheeled vehicle not limited to a traditional bicycle, while allowing a handler to stay as a pivot for a circle as opposed to running with the vehicle, while teaching a inexperienced rider to pedal forward, stop, steer and balance.   A steering control arm is mounted directly to the handle-bars in a horizontal position allowing an extension or said handle-bars. By controlling the steering, the rotation around the rear moment of contact with pound is controlled, aligning the front wheel with the back creating a vertical balance plane. By extension of the handle-bars by the arm, the vertical balance plane control is slowed and leveraged at the horizontal end to point of the jointed control arm.   By adding an extension with a hinged joint, allowing only vertical rotation, the handler can increase the size of the circle while still maintaining the control of both steering and balance, by pushing, pulling, lifting, or lowering the control arm.  As the experience and skill of the rider increases, after learning to pedal forward, stop, and balance with some skill, the hinged joint can be replaced with a universal joint to allow both vertical and horizontal movement, allowing the rider to then learn to steer, independently while still within the influence of the handler.   When the rider has acquired sufficient skill riding both directions, and can start, stop and steer independently, control from the handler is not required and the rider is safe and sound and confident enough with the skill set to ride alone.

A resilient seal (114, 214) is formed in one piece with the housing (10, 210, 300, 410), located on said rotor path and so extends between the outlet (12, 212) and the inlet (111, 211) in the direction of rotation of said rotor (15, 315, 350, 415) that the first rotor surface seals with, and resiliently deforms, the seal (114, 214), as the rotor (15, 315, 350, 415) rotates around the rotor path within the housing to prevent fluid flow from said outlet (12, 212) to said inlet (111, 211) past the seal. A passage (101, 201) may be provided to supply fluid to an under surface of the seal (114, 214) at a pressure that acts to urge the seal (114, 214) against the rotor (15, 315, 350, 415). The rotor path may be frustoconical with the first surface of the rotor (15, 315, 350, 415) also being frustoconical and being a mating fit with the rotor path.
