摘要： The sealing apparatus of the present invention is a sample cuvette cap having a hole for inserting the nozzle of an auto-sampler therethrough. Located within the lumen of the hole is a small detent ball that can be positioned to block the lumen. The detent ball, which can be spring-operated or gravity-operated, blocks the fluid flow in the hole in its normal, closed position. When the auto-sampler nozzle hits the ball, the ball becomes deflected to one side into a recess, due to a difference in the nozzle axis relative to the center of the ball. By the dislocating the detent ball, the nozzle can be inserted into the cuvette smoothly as the air goes in and out through the space around the nozzle. This allows the pressure in the cuvette to be kept constant. After the nozzle is removed, the ball returns to its original position by gravity or by the force of a spring, resealing the cuvette. All of the parts for the sealing apparatus are solid parts which can be easily cleaned and reused. Because there is no non-recoverable distortion or damage to the sealing mechanism, it can be re-used after cleaning.

摘要： Disclosed herein is a computerized blood analyzer system. The system includes a clinical analyzer CU and a blood analyzer AU. The clinical analyzer has a computer which issues commands and instructions to the AU as desired. These commands and instruction's include retrieval and storage commands and instructions. The blood analyzer unit AU is electronically connected to the CU and operates upon the commands and instructions of the CU. The AU generates test results which are stored in the computer. The computer has storage media for storing the results. The storage media comprises an aggregate database which includes at least two parts, namely a working database and an archived database. It is preferable in many case for the aggregate database to include a back-up database. Each of the databases stores the data in similar data fields, organization and structure comprising symmetrical-like databases. This enables a single set of commands and instructions to store and retrieve the data.

摘要： In a magnetic resonance imaging system, object movement along an axis associated with readout magnetic gradient pulses is detected, quantized and compensated for in reconstructing an image slice. Phase-encoding magnetic gradient pulses in the sequence are arranged so that low-order phase-encoding pulses are distributed substantially uniformly during scanning time. In an N-slice acquisition, object movement is determined y arranging each of the N sets of phase-encoding gradient pulses comprising a multi-slice sequence such that at each scan time, at least one of the N sets contains a low-order phase-encoding gradient pulse. During data acquisition, echoes returned from low-order phase-encoding gradient pulses have sufficient signal-to-noise ratios to identify object position along the readout axis. Identification of object movement from one slice may be valid for other slices relatively adjacent physically in the object, so that all N slices are movement corrected during image reconstruction. Two-dimensional object position may also be identified and corrected by suitably exchanging the axes of N sets of pulses within a sequence. For a single slice acquisition, object position may be identified when scans associated with low-order phase-encoding gradient pulses are distributed evenly during imaging. After one-dimensional Fourier transformation, object position relative to a reference box function is determined using cross-correlation.
