Abstract: Introduced here are retinal cameras having one or more optical components whose position can be modified so that the left and right eyes can be imaged during a single imaging operation. Collectively, the optical component(s) may be referred to as an “optical assembly.” An optical assembly can include the objective lens, lens tube, and other optical components such as mirror(s), light source(s), capturing medium(s), etc. An optical assembly of a retinal camera may be movable between a first position and a second position along an arcuate path. By moving the optical assembly between the first and second positions along the arcuate path, the retinal camera can align the lens tube with the left and right eyes of an individual while clearing her nose. Thus, the retinal camera may generate images of the left and right eyes during an imaging procedure without requiring that the individual move her head.

Abstract: A product change tool for selectively engaging a product change element with an IC tester interface and disengaging the product change element from the tester interface includes a mobile frame mounted to a base frame and constrained to move relative to the base frame along an axis of linear movement, and a force mechanism for urging the mobile frame to move along the axis of linear movement relative to the base frame. The force mechanism includes first and second links pivotally connected together at their proximal ends and secured at their distal ends to the mobile frame and the base frame respectively. The distal ends of the links are spaced apart along the axis of linear movement and the proximal ends of the links are between the distal ends relative to that axis.

Abstract: A flexural pantographic mount for use in a helical scan magnetic tape transport, the mount being a boxed leaf stiffened flexural pantograph mount, for holding and varying the position of a moveable head in a helical scan automatic scan tracking magnetic tape transport. The mount includes a moveable body such as a magnetic transducing head assembly coupled at one end of first and second generally parallel spaced apart elongated flexural pantographic leaves configured at the opposite free ends thereof for attachment to a fixed body. Each leaf includes first and second integrally formed and bent leaf edge extensions, which act as side stiffeners. A triangularly configured opening and a trapezoidally configured opening are formed in each leaf with each opening being configured to include tab projections for bending into the opening to provide transverse or lateral stiffening.

Abstract: An apparatus for an axially displaced flexural bearing support assembly including a unitary or monolithic bearing support base member having a bearing receiving tube supported by a first and second generally parallel arrangement of flexural spoke members to control bearing pre-load due to axial differential expansion while eliminating radial displacement of the spindle or shaft supported within the tube. The spoke members of each arrangement include a plurality of spoke members arranged in parallel planes generally perpendicular to the axis of a spindle insertable within and supported within the tube by means of bearings. In the preferred embodiment, there are three spokes for each set in each plane, with the spokes being equiangularly displaced.
