Abstract: A controller (30) based chromatography system (2) especially designed for flexibility of operation with ease of use and an icon based control panel (32), has a number of function panels (34), each having a function key (36), one or more indicator indicia (40) in the form of icons, letters or numbers, and associated indicator lights (38). A switching valve (4) is used to provide a mixture of two or more solvents (6, 8) to a peristaltic pump (12). The cyclic nature of the pump and mixer can create a resonant condition resulting in poor quality information from the UV monitor (20). The system minimizes this by the judicious selection of the total cycle time T for the switching valve. This can be done using a random number manipulated in a manner to come up with each time T. Alternatively, an irrational number is combined with the pulsation frequency of the pump to create each time T. A valve driver circuit (170) used with a valve (172) of the type which requires a higher voltage switching signal (174) and a lower voltage sustaining signal (176). The system permits the user to use three different nominal flow rate calibrations for peristaltic pumps using tubing having three different diameters (82, 84, 86). In addition to the precalibrated settings, the system can be user calibrated when desired.

Abstract: The widths of pulses in an incoming pulse train are monitored by successively measuring the duration of the pulses in the pulse train and enabling a timing device when the duration of any of the pulses is more than a preselected magnitude. The timing device is reset and restarted when the duration of any of the pulses is greater than the preselected magnitude. An output signal, indicative of an acceptable condition, is produced when the timing device indicates the expiration of a predetermined time delay. An output signal, indicative of a non-acceptable condition, is produced when the duration of a pulse in the incoming pulse train exceeds the preselected magnitude. This invention encompasses both the pulse width monitoring method and circuits which perform this method.

Abstract: An optical reader for scanning optical marks from a substrate. The reader employs a novel optical geometry to eliminate undesirable specular reflections from entering the optical detection system. A stage area is provided for receiving the substrate, the stage having a window through which an incident beam of light passes at an oblique angle with respect to the window. A retrocollection system is used to return reflections from the substrate to the optical assembly. By directing the beam at an oblique angle with respect to the window, specular reflections are not collected in the retrocollection system and thus are not received by the optical detection system. The invention also utilizes a permanent magnet, direct current motor for controlling a scanning mirror, and further has a motor control circuit for preventing the introduction of electrical noise from the motor during the scan. A sensor may be provided to detect the presence of the card on the stage and provide "on demand" scanning.
