Abstract: In various embodiments, a trocar cannula may be configured for insertion into an eye to facilitate insertion and removal of instruments during surgery. The cannula may be affixed to an overcap (to inhibit rotation of the overcap relative to the cannula) that includes a seal. In some embodiments, the seal may be overmolded into the overcap or may include a wafer that is fixed between the cannula and the overcap to inhibit rotation relative to the cannula and the overcap. In some embodiments, the cannula and overcap may snap together through a tab/slot interface in a permanent fashion such that the cannula and overcap may not be separated without damaging the cannula or overcap. In some embodiments, a vent cannula may be receivable in the slit of the seal for allowing fluids to vent from the eye through the cannula (which may include an indentation to frictionally engage the vent).

Abstract: A control display positioning system includes three vertically oriented hinges and a horizontally oriented hinge attached to the back of the control display. Two arms are used to connect the three vertically oriented hinges one to another. In each vertically oriented hinge is a central space for the passage of electrical cables therethrough. Also in each vertically oriented hinge is a washer stack that provides the necessary friction forces for the control display positioning system to remain in a selected position after being repositioned by a user.

Abstract: Systems and methods are provided to integrate disparate media services and applications across an organization. The media services are connected to an interoperable media services bus by creating a connector API for each service, thereby enabling the media services to exchange messages in a standardized format related to transactions to be performed involving media assets and/or metadata associated with media assets. Media assets are advantageously transported between different media systems using a transport interface that hides details of the transport operation from the sender and recipient media services. Each media service provides its own file transport parameters defining procedures for obtaining media assets therefrom and writing media assets thereto; the transport service determines particular protocols for each transport operation based on the information provided by the sender and recipient media services.

The media services are connected to an interoperable media services bus by creating a connector API for each service, thereby enabling the media services to exchange messages related to transactions to be performed involving media assets and/or metadata associated with media assets. To support complex transactions involving coordinated activity by multiple media services, an orchestration service advantageously performs a coordinated sequence of request/response transactions, referred to as a “workflow.” The workflow may include requests conditional on responses to previous requests, multiple parallel requests, a combination of synchronous and asynchronous requests, and so on. Multiple workflows may be managed concurrently.

Abstract: A fiber optic illuminator is provided comprising an optics bed, a light source, a collimating lens, and a condensing lens. The light source is mounted in a fixed position with respect to the optics bed. The collimating lens is mounted in a fixed position with respect to the optics bed and collimates at least a portion of the light from the light source. A condensing lens receives the substantially collimated light output and focuses the collimated light output to optically couple to an optical fiber. The condensing lens may be mounted on an adjustable mount. The tolerances of the fixed optical elements i.e. light source and collimating lens allow the fixed optical elements to be positioned with a minimal amount of variation where the variation is determined by manufacturing tolerances associated with these individual elements and their mounts and couple them to the optics bed.

Abstract: A cursor control stick includes a rigid tube having an outwardly-tapering conical throughbore and horizontal protrusions at its base, and a plunger having an outwardly-tapering conical body shaped in correspondence with the throughbore. The plunger slidably fits inside the rigid tube and includes a neck which extends beyond the rigid tube and which is adapted to be manipulated by the user. Electrically-conductive biasing means is disposed beneath and in contact with the plunger, and pressure sensitive resistive material is disposed beneath and in contact with the horizontal protrusions. A base containing electrical circuitry is disposed beneath both the electrically-conductive biasing means and the pressure sensitive resistive material.

Abstract: A word processing system having a transparent display for previewing printed documents includes a keyboard for inputting character data and format data, a read only memory for storing process steps for displaying and printing input character data in accordance with the input format data, a processor for processing the input character data and the input format data in accordance with the stored process steps, and a display for previewing printed documents. The transparent display comprises a transparent display for displaying characters, a backlight background for supporting a blank form and a printed circuit board connected to the perimeter of the display glass. The transparent display is configured so as to accommodate the passage of a blank form between the front glass and the support plate so that characters displayed on the front glass appear superimposed over the supported blank form.

Abstract: A hinge fastens a display screen to a keyboard base, and uses a frictional force generated by one or more compressed friction washers to control angular motion of the display screen with respect to the keyboard base. The hinge includes two shoulders defining inwardly-facing flat abutment surfaces separated by a first distance, the two shoulders being disposed on the keyboard base, and a knuckle having a pair of outwardly-facing flat abutment surfaces separated by a second distance which is less than the first distance, the knuckle being disposed on the display screen. Also included in the hinge is at least one compressible friction washer, disposed between the knuckle and the two shoulders, and having a thickness which is greater than a difference between the first distance and the second distance, but which is compressible to less than the difference. Each of the two shoulders, the knuckle, and the at least one compressible friction washer has an alignable throughbore.
