    摘要： An optical code reader is provided including imaging circuitry having an array of photo sensing devices capable of sensing light incident on the array and outputting a plurality of pixel signals corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results. A focus analysis software module executable by the control and logic circuitry determines the focus quality of the received pixel signals. A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals of the plurality of pixel signals in accordance with the selection control signal.

    摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.

    摘要： A semi-retroreflective optical scanning system has an optical scanning element which directs a scanning light beam via a stationary holographic optical element in a scan path across indicia to be read. Light from the indicia is collected by an optical collector, such as a lens or a mirror, which focuses it onto a small optical detector via the scanning element. The field of view of the optical detector scans across the indicia in synchronization with the outgoing scanning beam from the holographic optical element. Since the incoming reflected light is not limited by the aperture of the scanning element, the signal-to-noise ratio remains high even when a small scanning element is used. In a further embodiment the light source, scanning element collector and detector are provided in a common plane, the collector and scanning element sharing a common optical axis and a light source being provided substantially off axis to allow reduction in the scanning element size. In a further aspect of the invention a solid state reader is provided capable of establishing the distance to the target by sensing the exact position on the detector at which the target is imaged. According to yet a further aspect of the invention the problem of specular blinding is overcome by providing a plurality of sensors activated in a dynamic on-off sequence, for example a random sequence.

    摘要： An improved monocyte activation test is described that is better able to detect non-endotoxin pyrogens in medical products, in which a sample is incubated with a monocyte-containing reagent in an assay system comprising at least one surface comprising polypropylene. The invention also concerns assay systems for use in these tests that include at least one microtiter well having at least one interior surface comprising polypropylene and having a shape such that monocyte-containing reagent is concentrated in the well to provide greater cell to cell contact. The invention also relates to a diagnostic kit that can be used to test for the presence of non-endotoxin pyrogens in a sample.
