摘要:
An apparatus and method of automated blood cell analysis uses technologies from other systems to create a new, robust, improved type of automated microscope, which uses electronic motors and a closed loop control system to minimize ambient factors, such as jarring and temperature changes. Pre-stained blood smear slides are first coated with a thin film of oil and are loaded into a carousel from which they can individually be analyzed. The slides are moved under a low magnification microscope; an optimal area of examination is determined; a focal plane map is calculated for that area, and the positions of white blood cell candidates are computed. The slide is then moved under a high power microscope where a refined focal plane map is computed and the individual white blood cell candidates are imaged. The cells are preclassified and the images are made available for analysis by the technician. Additionally, samples of red blood cells, equivalent to what the technician would do manually, are imaged and presented to the technician for evaluation. The technician may make notes on those cells, both red and white blood cells and archive them.

A modular automated diagnostic analyzer having a fluid entry module for sample aspiration, a valve module for selecting fluids and a pump module for fluidic movement so that a biological samples does not come into contact with the valve system through which calibrants and air are introduced to the fluid path. The fluid entry module encloses an aspiration tube rotatably and slidably engaged with the analysis mechanism chassis to move to different positions for the introduction of fluids into the analysis apparatus from different types of sample containers. A wiping seal removes residues of aspirated fluids from the exterior surfaces of the aspiration tube with the residue being aspirated into the analysis apparatus for disposal. Sensor modules mounted in a sensors chamber are structured to mechanically stack and interlock and include film sensors with use life record memories and each sensor module includes a fluid tight sealed passage and a sensor element. A fluid selection valve of highly polished ceramic material allows a valve cylinder passage to be selectively connected to fluid sources. A self-contained reagent pouch housing contains calibrants including tonometered calibrants in reagent pouches wherein each pouch wall includes multiple layers of materials wherein at least one layer is a thin, flexible glass material. The walls are extended to form a filler neck sealed by heat and pressure along a sealing line below a filler line so that no bubbles are trapped in the reagent pouch.

An assay device and method for measuring the concentration of HDL-associated cholesterol in a blood-fluid sample are described. The assay design is such that removal of non-HDL lipoproteins from a sample and assay of HDL cholesterol in the sample occur without interruption of the assay. The device also prevents interference by reagents used for the HDL assay with other assays carried out on the same sample.

The invention relates to a decoratively finished product comprising a substrate made of polyphenylsulfone (PPSF), polycarbonate (PC), or ABS thermoplastic fabricated on a fused deposition modeling (FDM) machine or made of photo-curable resin or photo-curable resins blended with filling materials such as ceramic powder, nano-clay particles or nano-carbon tubes fabricated on a SterioLithography Apparatus (SLA) or made of powdered aluminum, glass-filled nylon or other powdered polymers fabricated on a Selective Laser Sintering (SLS) machine having a solid shape or hollow shape including internal cavities, channels or internal reinforcing structures to which either a metal surface is electroplated or applied by a plastic electroplating vapor deposition method or a finish simulating a range of natural and synthetic materials is applied using a water transfer printing method. The decoratively finished thermoplastic product includes various favorable characteristics, such as, being lightweight, exceptionally strong, scratch-resistant, and in the case of PPSF, flame retardant, resistance to many chemicals, capable of integrating imbedded components and possessing high thermal characteristics.

The logic analyzer interface assembly connects to a unit under test (UUT). The interface assembly includes an interface board having interface contact points matching the pattern of the UUT contact points. The interface board is mounted to a transfer interface including a probe plate and multiple spring loaded probes extending through the probe plate. The probes contact the UUT contact points at one end and the interface contact points at the other end. When assembled, the UUT and interface assembly form a sandwiched testing assembly that can be inserted into a chassis to aid in approaching an “at speed” observation opportunity.

A system for acquiring, processing, storing, analyzing and reporting data relating to the condition of a road or other pavement surface (102) in real time. The system includes a digital camera (104) mounted on a vehicle and positioned relative to a pavement surface (102) so as to capture images of the pavement surface (102) while the camera (104) is moving relative to the surface (102). The system also includes an illumination assembly (100) to illuminate the region from which an image is taken and an interface between the digital camera (104) and at least one computer. The system also includes a processor in the computer for processing the images to detect and classify cracks and other pavement surface (102) features.
