Abstract: A hand-held optically readable information set reader includes a user supported information set reader for reading information sets at distances from the reader within a certain operative range. The reader includes a plurality of optically readable information set sensors that generate an output signal according to an image of an information set incident thereon. The information set image is captured and sent to a processor, and at least a portion of the output signal generated by information set sensors is stored in memory during a reading operation wherein a first portion of the output signal is assembled with a second portion of the output signal such that the information set is thereby read.

Abstract: Methodology which avoids the problems associated with interference from whole blood is provided for instrumented determination of platelet binding function. Particularly, small particles to which fibrinogen is bound, and which contain an infrared light absorbing dye, are used to determine the binding of platelets in a whole blood sample to the fibrinogen. Agglutination of the platelets with the coated particles is determined by a change in infrared light absorption characteristics.

Abstract: A portable hand-held reader unit for reading two-dimensional information and generating an image therefrom wherein an optical axis of the reader is oriented obliquely to the surface containing the coded information. The reader includes a sensing system designed such that the rectilinear dimension of the generated image corresponding to an axis of the coded information undergoing the most distortion from oblique reading is magnified, by the lens system or the resolution configuration of the image sensor, to a greater extent than that of the rectilinear dimension undergoing the least distortion from oblique reading. Alternatively, the sensor is oriented relative to the optical axis such that the received image does not exhibit the distortion which may result from oblique reading. The coded information may contain height-to-width ratio of the coded information such that the generated image can be automatically corrected for distortion from oblique reading.

Abstract: An image capture system (100) having an image capture module (102) and a terminal unit (104) captures both photo images and coded images. An alterable optical path of the system (100) operates in a first configuration when capturing coded images and in a second configuration when capturing photo images. Captured images are presented on a display (114) as they are captured. A user of the system (100) may parse through captured images to select one or more of the captured images for permanent storage and/or transmission to a remote location. The system (100) operates to identify coded targets within captured images, to prompt the user to select one or more of the identified coded targets and to decode the selected coded targets. The image capture system (100) may direct a user to reposition the system (100) so that a decodable coded image will be captured. The image capture system (100) communicates over wireless and wired networks with remote computer systems (307), personnel, and mobile units (307).
