Patent CA-2192276-C (CA)
Title: Transducer for sonic logging-while-drilling
Inventor: ARON JEFFREY B
IPC: E21B47/01
Filed: 1996-12-06
Granted: 2005-02-08
Abstract: An acoustic wave transducer useful in sonic logging while drilling a borehole includes an array of transducer elements mounted circumferentially around a drill collar. The elements are bonded in an elastomer ring that is received in an external groove in the collar and are protected by a shield having windows. The elements are electrically connected in parallel so that when excited by an electrical pulse, the elements generate a monopole acoustic wave that propagates out into the formation. When used as a receiver, the elements detect averaged acoustic waves from the formation around the circumference of the collar and have minimum sensitivity to multipole waves traveling through the drill collar.

Granted: 2005-11-08
Abstract: An articulating surgical instrument with an articulation transmission assembly for remotely articulating the end effector of the instrument is disclosed. The instrument includes a body with a housing mounted on the instrument, oscillating and rotating members, and an actuator rotatably mounted on the housing and secured to the rotating member. The oscillating member is seated rotationally stationary within the housing. The rotating member fits into the oscillating member, and has a drive shaft extending into the body for translating rotation from the rotating member into reciprocation of an elongated transmission rod attached to the drive shaft.  First and second sets of unloading teeth are displayed on the oscillating member and actuator, respectively. First and second locking teeth are displayed on the oscillating and rotating members, respectively. The assembly provides ratcheting rotation for precisely positioning the end effector in discrete positions. Since the assembly has a ratcheting mechanism, it is "fail safe" when a force is applied to the end effector to prevent the component parts of the assembly from breaking. In the preferred embodiment, the frictional forces between the unloading teeth are less than those between the locking teeth. Therefore, the force which the surgeon is required to apply to the actuator of the assembly to cause articulation of the end effector is less than that which would be necessary to articulate the end effector when a force is applied on the end effector itself. The instrument may be used for endoscopic as well as conventional open surgical procedures.

Abstract: Formation tops correlation is interpreted between sampled log curves by a weighted combination of covariance, the ratio of standard deviation, and the ratio of summed amplitude. This covariance function is computed and evaluated appropriately for the geologic environment over a sliding analysis window. Correlations are determined for any number of wells and any number of events in each well. Geologic rules are used to establish a parameter for the algorithm operation and for the analysis of the resulting function. The geologic rules include bounding guide horizons, sequence rules, and a covariance cutoff parameter. Bounding horizons are picked from pre-existing seismic or geologic interpretations and from map grids. The rule set includes onlap, truncated, conformable, and unstructured sequence definitions. Additional geologic complexity such as crossover, repeat sections, and inverted sections are accommodated by the rule set. Back-correlation for cross-over sections and loop-tying for map interpretation are performed for validation.

Abstract: The invention concerns a bumper for a motor vehicle which is constructed mainly of moulded plastic parts and optically appears to be part of the vehicle body. The bumper consists mainly of a support part (10) extending across the vehicle, three absorbing elements (12, 14, 14') that can be inserted into the support part, and an elastic exterior          (See formula I) shell (16). On the lateral end sections, the support part (10) has lateral shells (22, 22') which extend between the lateral absorbing elements (14, 14') and the exterior shell (16). In a collision, the lateral shells (22, 22') yield backwards under the deformation of the absorbing elements (14, 14'), so that components attached to the lateral shells are protected from damage.

Abstract: An adaptive pixel multisampler (24) generates pixel data for display using an interlocking sub-pixel sampling pattern P and a frame buffer (26) organized as a per-polygon, per-pixel heap (64). The interlocking sampling pattern P provides the advantages of a multi-pixel shaped filter without pixel-to-pixel cross communication and without additional sub-pixels. The per-polygon, per-pixel heap (64) allocates frame buffer memory so that each pixel will have one set of data stored in the frame buffer (26) for every polygon that influences that pixel. This memory allocation scheme can significantly reduce frame buffer memory requirements. The polygon data is blended to properly handle processing of transparent polygons and polygon edges without the degradation of image quality found in conventional computer graphics systems.

Abstract: An apparatus for controlling rotation of an outer sleeve member relative to an inner cylindrical duct member is used in a drilling system for controlling steering of a downhole drilling tool. The apparatus includes an annular swash plate pump and a stack of annular brake disks in the space between the members. The pump is driven by the rotation to pump fluid into a supply cylinder driving the brake. An orifice controls escape of the fluid from the chamber at a controlled rate.  The rate is controlled to maintain a balance between the pumping rate and the brake pressure to keep the rotation at a required rate. The apparatus is used in the drilling system which includes a shallow bend in the drilling tool and a system for rotating the bent drilling tool slowly about a longitudinal axis of the drilling tool while the drill bit rotates more rapidly. The controlled orifice further allows the slow rotation to be halted at a predetermined orientation of the bend axis so as to effect a change in drilling direction.
