Abstract: A large scale, non-blocking fiber optic cross-connect system consists of multiple stages, including a central multifiber per connection system. The number of ports of this cross-connect system scales to over 10,000, in an incremental, modular, field expandable approach. Two separate arrays of “edge” cross-connect systems using KBS methodology are positioned on opposite sides of a central core cross-connect system, wherein the core system is comprised of switchable blocks of multi-fiber trunk lines, each terminated in a single connector that is reconfigurable by robotic means. The trunk lines between edge cross-connects are controlled by a trunk line management system to provision/deprovision blocks of multiple connections at a time in a “core” cross-connect circuit block between edge cross- connects. The core system is configured to controllably interconnect the physically separate edge cross-connect systems which concurrently direct data along selected paths to and from the central core circuit block.

Abstract: Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body has the shape of two end-to-end Y's forming a central segment, branch segments extending from ends of the central segment, and extension segments extending from the branch segments, to collectively form four unenclosed cell openings that are semi-hexagonally shaped. Some embodiments include reinforcement segments extending into respective cell openings, voids extending through respective adjacent branch and extension segments, an underbody gap under the central segment, a single stud-welding stud for the mounting feature, and/or a collar-and-stud connection between the anchor main body and a stud-welding stud of the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed semi-hexagonal cell openings of adjacent anchoring devices cooperatively form substantially hexagonal cells.

Abstract: Seal integrity indicators for sterilization containers are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility. An exemplary seal indicator includes an invertible projection formed with the container gasket that is not visible from outside the container until inverted, due to force applied by the lid, to extend through an opening in the container body. Closure mechanisms for sterilization containers also are provided.

Abstract: An integrated haptic system may include a digital signal processor and an amplifier communicatively coupled to the digital signal processor and integrated with the digital signal processor into the integrated haptic system. The digital signal processor may be configured to receive a force sensor signal indicative of a force applied to a force sensor and generate a haptic playback signal responsive to the force. The amplifier may be configured to amplify the haptic playback signal and drive a vibrational actuator communicatively coupled to the amplifier with the haptic playback signal as amplified by the amplifier.

Abstract: An automated fiber optic patch-panel/cross-connect system comprised of a stacked arrangement of multiple replaceable modules, including a first multiplicity of fiber modules, each with a second multiplicity of reconfigurable internal fiber connectors; a common robot module shared among fiber modules, wherein any connector within a fiber module in the system can be moved to any other connector of any other fiber module in the system; a power management module that distributes electrical power to the fiber modules and the robot module; and a server module that generates commands that are placed on communication bus to activate robot and fiber modules. The modules are physically separated and spatially arranged to be serviced replaced without interrupting fiber connections previously established in the system.

Abstract: A device and methods for cleaning an end of a fiber optic cable including a cleaning cartridge system for dispensing and usage monitoring of fiber end face cleaning fabric. The cleaning cartridge system includes a spool of cleaning fabric; an actuator that drives a fabric advance roller; a pressure sensor that detects when a fiber end face is in contact with fabric and outputs a contact-indicating signal; an internal control circuit that drives the actuator to advance the cleaning fabric in time-relation to the contact-indicating signal; and an external controller that determines proper advance of the cleaning fabric and consumption of the cleaning fabric over time. Methods of maintaining low loss physical fiber-optic connections in an automated cross-connect system use the cleaning device and methods.

Abstract: Indicators for indicating the integrity of a seal of a sterilization container are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is in one state and displays a first indicium, and if the sterilization container is not sufficiently sealed, the seal indicator is in another state and displays a second indicium. Thus, the seal indicator undergoes a visible change in state when the sterilization container transitions from unsealed to sealed, such that the user may be assured that the container is properly sealed to maintain sterility of the articles post-sterilization. Further, the seal indicator undergoes a visible change in state if the seal is subsequently broken, to signal to the user that the seal and the sterility of the container interior has been compromised.

The main body has the shape of two end-to-end Y's forming a central segment, two branch segments extending from each end of the central segment, and an extension segment extending from each of the four branch segments, to collectively form four unenclosed cell openings that are each semi-hexagonal in shape. Some embodiments include four reinforcement segments with each one extending into a respective cell opening, four voids with each one extending through respective adjacent branch and extension segments, an underbody gap formed under the central segment for refractory interlinking between cell openings, and/or a single stud-welding stud for the mounting feature.

Abstract: Closure mechanisms for closing and sealing sterilization containers and indicators for indicating the seal integrity sterilization containers are provided. For example, a container closure mechanism may be configured to distribute a closure force along a gasket to seal a container lid to a container body. Further, a seal indicator may visibly indicate at the container exterior whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is a first state, and if the sterilization container is not sufficiently sealed, the seal indicator is in a second state. Thus, the seal indicator undergoes a state change when the sterilization container transitions from unsealed to sealed or from sealed to unsealed, such that a user can ascertain whether the container is properly sealed to maintain sterility or whether the seal and sterility of the container have been compromised.

Methods to build out this system over time, in an incremental and non-service interrupting fashion, are described.
