Abstract: Disclosed herein are various telemetry systems and methods suitable for communicating a cylindrical volume of formation property measurements to the surface. Some system embodiments include a downhole processor coupled to a telemetry transmitter. The downhole processor determines a compressed representation of the formation property measurements and/or selects a subset of the measurements for transmission uphole. The subset selection can be based on selected radial distances having characteristics that potentially indicate features of interest to a user. Such features include bed boundaries, and the characteristics include sinusoidal variation as a function of azimuth, large changes in this sinusoidal variation versus radial distance, or inversion suggesting the presence of a bed boundary.

Abstract: A method is provided to assist adjustment for a movement path of a probe. A coordinate measuring machine includes a probe having a tip for detecting a surface of an object, and a movement mechanism for moving the probe, and measures a shape of the object by allowing the probe tip to scan the surface. A controller controls operation of the coordinate measuring machine by calculating a scanning path for allowing the probe tip to perform scanning movement and the movement path followed by the probe when the probe tip moves along the scanning path, setting control points on a line connecting each position of the probe tip and each corresponding position of the probe accepting a change in position of the control points by a user, and changing the movement path accordingly. A guide point allows the control points to move collectively.

Abstract: There is provided a speed monitoring device which can use a low resolution position sensor and provide a high speed response without false detection. The speed monitoring device stores, in a memory unit, a permitted margin PM, a comparison distance VC which is a maximum movement distance permitted for a moving element within one cycle period, and positional data P(t?nT) (n is a natural number equal to or less than M) of the moving element obtained from the present time t to M cycles ago. During speed determination, whether |P(t)?P(t?nT)|>VC*n+PM holds true is determined for every integer n from 1 to M. When the inequality holds true, it is determined that the speed exceeds the speed limit.
