Title: A method of noise reduction applicable to continuous-field and other data       acquired along lines
Inventor: GLEAVE RICHARD JOHN
IPC: G01V1/28
Filed: 1994-01-24
Abstract: A method of data surveying for use, for example, in marine gravity surveying wherein lines of gravity readings are corrected for line-to-line instability, and thereby their noise content reduced. Initial lines of data are treated in order to produce first and second sets of lines of data having differing frequency characteristics in respect of noise content, and these sets of lines are combined. The gravity data is acquired at high density. The above steps may be followed by median filtering and higher accuracy and resolution is obtained than is usually considered possible for marine gravity surveying. 2 - D grid filtering is used. <IMAGE>

Title: Controling the loading of a recording medium using PWM signals
Inventor: SAITO KENICHI
IPC: G11B17/22
Filed: 1994-03-24
Abstract: A loading apparatus for a recording medium such as a disc-like recording medium includes a transfer member, a drive unit, a detector (101) and a controller (102). The transfer member moves between a recording medium changing position and a disc-like recording medium recording and/or reproducing position. The drive unit drives the transfer member. The detector (Fig. 19, not shown) continuously detects a position of the transfer member in accordance with a movement of a movable part (29) of the drive unit. The controller controls the drive unit so that a moving speed of the transfer member is slowed down prior to arriving at the changing position and the recording/reproducing position on the basis of the detection signal from the detector. This is done by varying the duty cycle of a pulse width modulated (PWM) signal applied to the drive unit when the transfer member reaches certain positions.
