  • Publication number: 20210228067
    Abstract: A medical imaging system includes multiple illuminating endoscopes with cameras having image sensors exposure control and a frame memory. The exposure control of each camera activates the frame memory and light source for collection of selected frame images by the frame memory. A data link among the endoscopes synchronizes exclusive initiation of the exposure controls in recurring serial order for activation of each respective frame memory and light source.

  • Patent number: 6313868
    Abstract: A video camera system is described which may store operating parameter information for reading by the system to provide optimum operating conditions, which may collect information reflecting system uses for later reading by the system to provide a performance history, and which is relatively small and operates with a reduced number of electrical lines to transmit electrical information.

  • Patent number: 6166538
    Abstract: An electronic autoclave cycle passively records the number of thermal cycles to which an instrument has been subjected in a steam autoclave. When a sterilization cycle has been completed, and the instrument is next energized in use, a microprocessor is employed to read the sensor and record the occurrence of a sterilization cycle. Information as to the cumulative number of cycles through which the instrument has been subjected is stored in a non-volatile memory. This data is suitably displayed on a display panel. The sensor employed uses either the Curie temperature or a temperature near but below the Curie temperature of a ferromagnetic material by first magnetizing the material and then, later, checking its flux density to determine whether a thermal cycle has occurred. In a first embodiment, a Hall effect sensor is used to directly measure the magnetic field strength of the magnetizable material.

  • Patent number: 5841491
    Abstract: A system for transmitting an image through the fiber bundle of an optical fiber endoscope is provided, characterized by an electronic filter for substantial removal of distortion such as that introduced by passage of the image through the bundle. The filter is configured with a variable characteristic such as cutoff frequency which can be matched to a predetermined parameter of the bundle such as the density of individual fibers. Thus, the filter can be easily modified to provide optimal performance if the fiber bundle is replaced or modified.

  • Patent number: 5696553
    Abstract: A video camera of the type in which the camera head is detached from the camera control unit, and coupled to the same with a cable is provided. The driving circuitry for the imager is situated at the camera head. Compensation circuitry is included to adjust the phase relationship between the timing signals passed to and from the camera control unit over the cable to at least partly compensate for delay through the cable.

  • Patent number: 5428386
    Abstract: A remote endoscopic video camera system is provided which is capable of providing both left and right eye pre-video signals for generating a three-dimensional image. The left and right eye pre-video signals are provided by first and second imagers which are capable of being enclosed in a single camera head, which, in turn, is capable of being coupled to the remaining camera circuitry through a single cable, without causing substantial interference between the two imagers.
