  • Publication number: 20250240530
    Abstract: An endoscope and related method comprise a proximal handle and a distal shaft having an insertion end. A housing comprising a camera assembly may be mounted on an insertion end of the shaft and include at least one lens and an image sensor. The camera assembly housing is rotatable about an axis perpendicular to the long axis of the shaft, giving the camera assembly a variable field of view. The rotatable camera assembly housing may be mounted to the insertion end of the shaft so that the rotatable housing of the camera assembly comprises the distal-most element of the endoscope shaft or insertion end. The endoscope may include a circuit board having a first portion disposed within the proximal handle and one or more extension portions that extend within the shaft to the camera assembly and/or to a light source near the distal end of the shaft.

  • Patent number: 8752262
    Abstract: An exemplary method of retrofitting a brake onto an elevator machine that was previously installed in an elevator system includes selecting a surface of the elevator machine that rotates as a sheave of the machine rotates. A braking surface is provided on the selected surface. At least one brake member is installed in a position to selectively engage the braking surface.
