Abstract: A universal adapter system having a video camera mount and a digital camera mount for attaching a video camera and a digital camera to a single port of an optical observation device, such as a standard microscope, that allows for simultaneous video and digital camera imaging. An example digital camera mount includes a C-clamp attachment for attaching a standard, off-the-shelf digital camera and a sleeve attached to the adapter housing that allows use of an extendable zoom lens of the digital camera. The adapter may provide increased capabilities by use of a rotatable portion to allow positioning of the digital camera relative to the optical observation device, a parfocal zoom lens for simultaneous zoom adjustment of video and digital cameras, an auxiliary zoom lens, a fine focus adjustment for adjusting the video image independent of the digital image, a smartphone adapter, a Toric reticule and a light filter.

Abstract: Systems, methods, and products are described that provide for digital pathology image manipulation. One aspect provides for displaying one or more digital specimen images on a display device in one or more viewing windows arranged in one or more viewing configurations; and associating one or more images through one or more correlation processes comprising image co-registration, image locking, and image overlay processes. Other aspects and embodiments are also described herein.

Abstract: A potentiometer contained within a housing is operated from the outside by means of an operating member which extends inward through an orifice in a housing wall. The operating member engages the potentiometer drive stem with the aid of an O-ring slip clutch, and includes a flange which is spring-urged against the interior housing wall to inhibit internal explosions from propagating to the outside.

Abstract: First and second pressure sensitive diaphragm assemblies are mutually spaced at a substantially constant distance by a rigid member, whereby the diaphragm assemblies flex in unison in response to imposed pressure differentials. A longitudinally rigid but transversely flexible and resilient means such as a strut wire couples the diaphragm assemblies with a deflectable motion sensing means such as a cantilever beam bearing at least one strain gage. The coupling means flexingly accommodates to normal transverse deflection movements made by the motion sensing means, thereby significantly reducing both the strain on the motion sensing means and distortions in the readout obtained therefrom. In a preferred embodiment a hollow tube is employed to space the diaphragm assemblies. A motion sensing beam projects inwardly through an opening in the tube and is joined therein to a strut wire which extends inside the tube from one of the diaphragm assemblies.
