Title: Constant offset migration velocity analysis
Inventor: HENSON DOUGLAS W
IPC: G01V1/30
Filed: 1991-02-01
Abstract: ABSTRACT           A method for determining accurately the migration velocities for use in seismic migration processing of seismic data.  The method presorts the seismic data into common-offset sections. The common-offset data is then migrated repeatedly with a selected range of velocities. The migrated data for each velocity is further sorted into a common-image point profile. The correct velocity per depth may then be determined by either determining the least time moveout for the common-image point at each depth, or computing the semblance for each common-image point and each test velocity and selecting the largest semblance value.

A silence sequence replaces the captured command data packet such that no audible sound is heard by the user.  A link check command signal is also periodically transmitted by the base unit and acknowledged by the handset unit to evaluate the quality of the RF link toward trig-gering an automatic channel change or signaling an out-of-range condition.

Abstract: The method of this invention relates to preparing a bone to secure a prosthesis thereto by improving the mechanical interdigitation of bone cement and the bone and faciliting hemostasis of the bone.  First, the bone is mechanically shaped to expose cancellous bone in a desired configuration for reception of a joint prosthesis. A pressurized jet of dry-flowing gas is then applied to the exposed bone, to clean and dry the trabecular interstices of the exposed cancellous bone.  To further withdraw debris and liquids dislodged from the interstices of the prepared bone by the pressurized jet of dry-flowing gas, suction is applied to the bone concurrently with the application of the pressurized jet of dry-flowing gas. Bone cement in liquid form is then applied to the bone, with cement penetration into the cleaned and dried interstices of the bone.
