Title: Geological layer hardness profiling - during opt. percussive rotary drilling, allowing programmable numerical control
Inventor: FREDERIC MALINET
IPC: E21B49/00
Filed: 1992-07-31
Abstract: Determination of the relative hardness of different geological layers encountered during drilling is carried out by (i) receiving the voltage output of a sensor located at the level of the drilling tool, (ii) eliminating parasitic noise to leave a voltage signal representing reflection energy, (iii) filtering the signal in high pass and low pass filters, (iv) rectifying the filtered signal to obtain only positive values; (v) amplifying the signal to obtain an useful signal (A); (v) calculating the integral of the curve (10) representing successive signal (A) values by selecting a constant sampling time frequency (10a) to obtain a numerical magnitude (N) as output; (vi) processing the numerical magnitude to produce 24 bit coded information corresponding to a constant number of percussion blows or drill tool rotations; (vii) selecting a significant 8 bit coded information (N2) from the 24 bit coded information (N1); (viii) forming a moving average of the successive information portions. (N2) to produce successive signal (N3) outputs; and (ix) using these signals (N3) to trace a curve of the relative layer hardnesses as a function of the layer depth. USE/ADVANTAGE - In opt. pe4rcussive, rotary drilling. The process complies well with operator requirements and allows fully programmable numerical control.

Title: Inverted image contrast selector for radiography - has microprocessor taking numerical input, applying to inverter and correction curve to produce operator controlled display
Inventor: JEAN BOSSAERT
IPC: G06T5/40
Filed: 1992-09-01
Abstract: An X-ray tube passes X-rays through a patient, and a camera detects the output signal. The output signal is converted to digital form and passed to a microprocessor. The microprocessor determines the luminosity levels, and inverts them. The law applied to this conversion can be changed according to a family of curves of inverse luminosity/incoming digital information (21). Two user adjustable knobs act on two parts of the curve, at the dark end and light end of the scale, allowing the user to select the optimum transfer curve. ADVANTAGE - Contrast knobs effect contrast change of inverted image proportional to knob movement.
