Abstract: A system and method for preventing germs, dust, and debris from being collected and inhaled by a user of a CPAP mask is presented. The user places his/her CPAP face mask into a storage case. The storage case has a connector for a hose used by the CPAP face mask when connecting to a CPAP machine. The hose is connected to the storage case and the other end of the hose has an end cap. A machine cap is further presented to place on the intake/output of the CPAP machine. The case has a housing, the case could be a storage case. There is at least one end cap that can be securely attached to a connecting port of the case. A second end cap for the end of the hose and a cap for the CPAP machine.

Abstract: A method comprising for deghosting seismic data is disclosed. The method includes the steps of acquiring seismic data by conducting a survey of a subsurface area of interest wherein the seismic data includes ghost data and estimating a time-varying wave height above the subsurface area of interest during at least a portion of the survey, wherein the estimation of the wave height is based at least in part on a remote measurement of the wave height during the survey. The estimated time-varying wave height is used to characterize the ghost data and deghost the seismic data based at least in part on the characterized ghost data.

Abstract: Noise may be filtered or attenuated from seismic data by building a four-dimensional volume using the acquired seismic data and then applying a random noise attenuation filter to the four-dimensional volume. The dimensions of the four-dimensional volume may include a trace number dimension, a time dimension, a shot number dimension, and a cable number dimension. The random noise attenuation filter may filter portions of the acquired seismic data if the seismic data is not correlated with respect to other seismic data in the four dimensional volume.

Abstract: A computationally-economical method for converting a set of areally-distributed seismic traces into a new, clearly-resolved, three-dimensional display of a volume of the earth without use of dip-dependent or azimuth-dependent migration velocities.
