摘要： The apparatus has a sensor disposed on the first end of an elongate connector by means of fixed interface link. A recorder unit is disposed on the second end of the connector opposite the first end. The connector is bendable within a predefined curvature range. When the apparatus is deployed into the sea, it is adapted to free-fall through the body of water and to land on the seafloor such that the sensor is spaced apart from the recorder unit. The apparatus is additionally adapted to substantially vibrationally de-couple the sensor from the recorder unit. The length of the connector is dynamically variable within a predefined range so as to minimise vibration coupling between the recorder unit to the sensor. Physical separation of the sensor and the recorder unit, together with the mechanical characteristics of the connector, ensure that the sensor is substantially vibrationally de-coupled from the recorder unit.

摘要： An apparatus for telemetering a downhole parameter from a well. The apparatus comprises a housing having a bore. The apparatus further comprises an annular main valve with an enlarged end positioned within the bore, with the main valve having a center of axis. A restrictor is concentrically disposed within the bore, the restrictor configured to define an annular passage with the main valve. The apparatus also includes: a pressure device for supplying hydraulic pressure to the main valve; a control valve, operatively associated with the restrictor member, for controlling pressure to the main valve; and a solenoid control valve assembly for activating the control valve. In one preferred embodiment, the solenoid control valve assembly comprises a controller for emitting an electrical signal, a coil that receives the electrical signal and generates a magnetic field, a solenoid static pole receptive to the generated magnetic field, and a solenoid moving pole responsive to the magnetic field so that the solenoid moving pole moves in a direction towards the solenoid static pole. A method for communicating a downhole parameter is also disclosed.

摘要： Geophysical measurement system employed during the drilling of a well borehole. The system employs a reference clock disposed within equipment at the surface of the earth and a borehole assembly which houses a downhole clock and at least one sensor. The borehole assembly is operationally connected to a drill string, which advances the borehole. At least one synchronization shuttle apparatus containing a shuttle clock is conveyed downhole to the borehole assembly to synchronize the borehole clock with the reference clock. Reference and borehole clock synchronization is maintained at one millisecond or less over a period of days. Outputs from the reference clock and borehole clock and sensor are combined to obtain a measure of a geophysical parameter of interest. Although the measurement system is particularly applicable to seismic-while-drilling measurements, it can be used in a wide variety of clock driven geophysical measurements.

摘要： A method to determine the systematic error of an instrument that measures features of a semiconductor wafer includes the following sequential steps. Collecting sensor data from measurement runs on front and back surfaces of a wafer while the wafer is oriented at different angles to the instrument for each run, yielding a front data set and a back data set for each angle. Then organizing the data in each set into a wafer-fixed coordinate frame. Reflecting all back surface data about a diameter of the wafer creates a reflected back data set. Subtracting the reflected back data from the front data for each wafer angle, and dividing the result by two, yields an averaged wafer shape for each load angle. Adding the reflected back data to the front data and dividing the result by two, yields an instrument signature for each load angle. The symmetric corrector is calculated by taking the average over all instrument signatures at each load angle. The symmetric corrector is successively rotated to the same angle as a front shape measurement and subtracted, yielding a calibrated wafer data set. A wafer mean is computed by averaging these calibrated wafer shape measurements. When the wafer mean is subtracted from the individual front side corrected shape measurements, a set of shape residual maps for each load angle results. The average of the aligned residuals is the asymmetric error. The systematic error is the sum of the symmetric and asymmetric errors.

摘要： A helically grooved flexible optical cable core comprising a plurality of helically laid flexible bodies 1 of sector-shaped cross-section is manufactured by drawing a multiplicity of flexible non-metallic reinforcing elements 2 under tension through electrically insulating plastics material 3 in a semi-liquid state; causing the plastics encapsulated reinforcing elements to pass through an elongate die 23 having an outlet orifice 25 of sector-shape, which die, between its ends, is of such a shape that reinforcing elements adjacent the arcuate surface 4 of the body are travelling at a greater linear speed than reinforcing elements remote therefrom, and which has a blade 26 protruding inwardly of the die and forming in the arcuate surface of the body a longitudinally extending groove 5; causing the body as it emerges from the die to follow a helical path with its grooved arcuate surface outermost and so cooling the helically advancing body that the plastics material sets; partially filling the groove in the arcuate surface with a grease and continuously feeding an optical fibre into the grease in the groove; laying up the helically advancing body with a plurality of helically advancing bodies of similar cross-section and construction to form a flexible core of circular cross-section which is rotating about its longitudinal axis; and taking up the rotating core in such a way that any residual torsion in the core arising from said rotation is removed.
