  • Patent number: 4582068
    Abstract: Systems and methods are disclosd for detecting the recurrence of physiological functions. The disclosed systems and methods are especially adapted for detecting the recurrence of a patient's respiration from a signal representative of changes in the patient's thoracic volume, despite the presence of cardiovascular artifact in the signal. A cardiovascular artifact filter suppresses the artifacts in response to a signal, generated by a cardiotachometer, which varies as and is proportional to the fundamental frequency of each artifact.

  • Patent number: 4537196
    Abstract: For suppressing cardiovascular artifact present in a respiration signal, a cardiovascular artifact filter suppresses artifacts in response to an output signal generated by a cardiotachometer. The output signal is proportional to the fundamental frequency of the cardiovascular artifact. Recurrence of respiration is determined by coupling the filter to a threshold detector. A minimum threshold level proportional to the maximum amplitude of the artifact is supplied to the detector for minimizing the false indication of respiration recurrence due to presence of an artifact in the respiration signal.

  • Patent number: 4533926
    Abstract: Novel strip chart recorders and strip chart recording paper are provided which are cooperable so that the recorder detects the proximity of a terminal edge of the paper, so that the recorder can signal this occurrence to the user enabling him to insert a new supply of strip chart paper in the recorder to avoid the loss of data. The recorder also cooperates with the strip chart paper to determine when paper is absent from the recorder, for example, when it has been exhausted, thereupon to signal this further occurrence to the user and take steps to avoid damage to the recorder which can result through its operation in the absence of paper in the recorder mechanism.

  • Patent number: 4520830
    Abstract: For medical examination purposes, an ultrasonic imaging device in which ultrasonic pulses are transmitted into a body of a patient and reflected therefrom. The reflected pulses are converted from ultrasonic to electrical signals by electro-acoustic elements which are then amplified by a time-gain-controlled device and converted for display on a CRT by a scan converter. Amplification of the time-gain-controlled device is controlled by an output voltage produced by a control voltage generator. The generator includes circuitry for automatically delaying the amplitude varying characteristics of the output voltage with time.

  • Patent number: 4513295
    Abstract: For recording medical information on a strip chart by a strip chart recorder associated with a fetal monitoring device, a communication is initially entered into a data entry system which includes a switching membrane having a plurality of switches forming a switching network underlying the membrane. A microprocessor scans the network to identify the communication and thereafter supplies the same to a liquid crystal display for view by a user of the system prior to transmission of the communication to the recorder for recordation.

  • Patent number: 4488812
    Abstract: A photometric analyzer and method are disclosed for analyzing particle containing samples. More particularly, a nephelometric apparatus and method are disclosed for analyzing baceteria samples. In the disclosed embodiment, the bacteria count of a bacteria sample is determined by photometrically comparing the sample to another sample having a known particle or bacteria concentration. Thus, in accordance with the invention, samples having a known bacteria count may be quickly and easily obtained from a "go" "no-go" test. The bacteria samples obtained according to the invention may be used as standardized bacteria concentrations for conducting Kirby-Bauer dilution tests.

  • Patent number: 4461302
    Abstract: A system for coupling a plurality of physiological signals across an isolation barrier. A plurality of physiological signals received at a number of signal inputs on the isolated side of the barrier are sampled during separate time periods and coupled to the primary winding of a transformer. The direction of signal flow through the primary winding is reversed during each said period. A pair of serial pulses of opposed polarities are induced in the secondary winding for each sampled signal. The pairs of serial pulses induced in the secondary winding are reconverted to the plurality of physiological signals on the non-isolated side of the barrier.
