  • Publication number: 20110137134
    Abstract: A method and system for objectively scoring intra-operative pain during general anaesthesia based on the patient's mean arterial pressure and heart rate. The index is used for closed-loop control of the intra-operative analgesia through adjustment of the drug infusion level according to fuzzy logic. It is further displayed along with other components of anaesthesia and important patient data on a monitoring display for presentation to medical staff.

  • Patent number: 7236832
    Abstract: A neuromuscular monitoring system comprises at least one neurostimulator to apply muscle-activating stimulation signals to a patient's body via at least one electrode, and at least one pressure waveform sensor to detect pressure waveform signals produced by a patient's muscle in response to the applied stimulation signals. The detected pressure waveform signals are processed and data related to these detected pressure waveform signals are displayed. A method for neuromuscular monitoring using pressure waveform sensors is also described.

  • Patent number: 6434329
    Abstract: A controllable camera support including a pivoting arm adapted to be rotatably connected to a pivot point defining a first rotational axis. The pivoting arm also defines a radial axis. The camera support also includes a camera holder mounted on the pivoting arm. The camera holder is displaceable along the radial axis. The camera further includes motors coupled to the pivoting arm and to the camera holder. The motors are adapted to impart rotational and radial motions to the camera holder. The camera support also includes a control device for controlling the motors. The invention also covers a system further including a focal adjustable, rotational, tilting camera mounted on the camera holder. When a target that is focused by the camera becomes obstructed, the control device is adapted to move the camera to another position all the while focusing on the target.
