Title: Method and apparatus for acoustic determination of porosity
Inventor: GEORGI DANIEL T
IPC: G01N15/08
Filed: 1995-10-02
Abstract: This invention provides a method and apparatus for non-destructive porosity determination of a reservoir rock sample from contact acoustic pulse travel time (or contact acoustic wave velocity) measurements. The apparatus includes a probe assembly 10 having transmitter 40 and receiver 50 transducers coupled to a computer system 20. The transducers are adapted to be pressed against a core sample 28. The computer system causes the transmitter to induce acoustic waves (shear or compressional) in the core sample, receives the signals from the receiver and determines acoustic transit times, acoustic velocities and porosity according to programmed instructions. The present invention further provides a method for determining the continuous porosity of rock samples to overburden conditions utilizing the measured velocities without the use of analyzing a large number of core plugs. <IMAGE>

IPC: G08C23/04
Filed: 1994-06-27
Abstract: A sensor system (10) in an interferometric arrangement has a sensor arm (24) and a reference arm (28). The reference arm (28) is in a stable environment and the sensor arm (24) is arranged to be subject to variations in strain and/or temperature. Radiation from a broadband source (12) propagates through the arrangement and a broadband interferogram is generated as an air gap (114) is scanned. The interferogram is recorded on an oscilloscope (126) and analysed using signal processing software on a computer (128). From the analysis the changes in group delay and optical dispersion of the light in the sensor arm (24) due to strain and temperature changes is measured, and values for the strain and/or temperature changes calculated. A narrowband light source (86) may be used for accurate calibration of path length differences during scanning. The strain and temperature on the sensor arm (24) may be calibrated or tested using clamps (30, 32) and a thermal enclosure (34). The system may also be configured in a tandem interferometry arrangement (200) including a sensing interferometer (202) and reference interferometer (204). <IMAGE>

Title: Stop motion device
Inventor: MINKLEY COLIN
IPC: B60T7/22
Filed: 1995-07-04
Abstract: A stop motion device for use in preventing or arresting movement, more especially as a safety device for a vehicle when reversing comprises detection means (26 or 51, 53, 50) moveable between an inoperative or retracted position on the near of a vehicle to a rearwardly extending activated or operative position. On detection of an obstacle by the detection means immediate automatic application of the vehicle brakes is caused to take place and also simultaneous retraction of the detector means back to the rear of the vehicle. Thus, for a reasonably cautious reversing speed for which the device is intended, braking distance of the vehicle is accommodated before it strikes the obstacle. Therefore, only light initial contact of the detection means (26) with the obstacle occurs. Where the detection means (51, 53) provides a transverse infrared detection beam (50), there is no actual physical contact with the obstacle.

Title: A CMOS inverter with a process, voltage and temperature-insensitive switching threshold voltage
Inventor: MONK TREVOR
IPC: H03K19/003
Filed: 1998-08-10
Abstract: The switching threshold of a CMOS inverter 31 is controlled by analogue control signals CTRL1 and CTRL2 which alter the transconductance of the upper and lower arms of the inverter. The control signals are derived from a bias circuit (figures 6 and 7) which is based on a dummy inverter circuit using small transistors. Process, supply voltage, and temperature insensitivity of the inverter switching threshold is achieved. The analogue control signals may be transmitted to the controlled inverters as digital codes which are reconverted to analogue signals before being applied to the control transistors. Alternatively, the digital control signals may be applied to a number of parallel switched control transistors (figure 11). An uncontrolled inverter 30 may be placed in parallel with the controlled inverter 31.
