IPC: G01N33/569
Filed: 1989-10-30
Abstract: A method for anyalyzing and separating the three major populations from a composite histogram of white blood cells is provided by identifying a modal value for both the lymphocyte (lymph) and granulocyte (gran) concentrations over respective first predetermined ranges in the histogram. 60% thresholds from said peaks are also determined and lymph and gran areas are estimated to provide lymph and gran curves. These curves are then subtracted from the histogram resulting in a mid population curve whose peak is determined and from which is derived left and right thresholds based on the mid population peak. The left and right thresholds are then applied to the histogram and the areas to the left, between, and to the right of the thresholds are integrated in order to derive the lymph, monocyte and gran areas of the histogram. The method provides discriminators with moving thresholds which vary in accordance with changes in the histogram and compensate for changes in conditions which affect the size distribution of the white blood cells. Apparatus for performing the method is also disclosed.

Inventor: WEYRAUCH ADOLF
IPC: G02B23/00
Filed: 1989-12-22
Abstract: The invention relates to a binocular telescope having a cardanically journalled inverting system mounted on a symmetrical double holder. This double holder is connected via a spring joint to a stationary non-movable base frame which is mounted at the pivot point of both inverting systems. An active movement damping device provides for a field image stabilization in the telescope. The monolithic spring joint provides a spring action perpendicular to the optical axis with the springs being thickened in the axial direction toward the edge to improve supporting capability. Shock protection is provided in the region of the support pivot point and contains an unlatchable latching device. The active damping device consists of a magnet system movable relative to a current coil fixed to the housing. This current coil exhibits a nonlinear effect in order to axially adjust the damping constant. A magnet field sensor is located in the current coil and controls the current flow through the coils via a circuit so that a specific, time-limited change of the damping constant is possible.

Abstract: An acoustic borehole logging system employs an acoustic transmitter excited by a sweep frequency tone burst to produce an acoustic output having a free-field frequency spectrum of at least one resonant frequency of vibration.  A closely-spaced acoustic receiver detects a borehole frequency spectrum that is representative of the acoustic transmitter free-field frequency spectrum altered by the effects of the properties of the subsurface formation materials comprising the borehole wall.  Such detected borehole frequency spectrum is recorded in correlation with depth as a log of the material properties of the subsurface formations surrounding the borehole.

Abstract: ABSTRACT OF THE DISCLOSURE      A sensor for a laser beam target which is comprised of at least one lateral effect photodiode, such that a beam of light from a laser can be focused upon the photodiode.  The photodiode has a left half and a right half.  A first circuit is connected to the left half of the photodiode and a second circuit connected to the right half of the photodiode.  Each circuit has the following components.  A transimpedance amplifier is connected to one half of the photodiode, such that the beam of light striking the half of the photodiode is converted to voltage levels.  A resistor is connected to the transimpedance amplifier thereby determining a dynamic range of voltage such that voltage levels within the range result in a positive value and voltage below the range result in a value of zero.  A unipolar differential amplifier is connected to the transimpedance amplifier.  The differential amplifier in the first circuit is linked with the differential amplifier in the second circuit, such that when the beam of light from the laser is to the left or right of centre a voltage of a positive value is generated in one or the other of the differential amplifiers.  A voltage comparator is connected to the differential amplifier thereby setting limits which define the physical centre of the photodiode and altering the voltage in the circuits when the beam of light from the laser is positioned within the limits of physical centre.  Signal means is provided for indicating to the operator the positioning of the beam of light from the laser.
