Abstract: A system and method for facilitating annotation of a digital document between first and second computing devices is provided. The system comprises a database/server that receives an original digital document from the first computing device and communicates a shared digital document to the second computing device. The second computing device receives and displays the shared digital document for annotation. The annotation produces an annotated digital document which includes annotated document data overlaying the original document without modification to the original document data. The original digital document may be edited at only the first computing device.

Abstract: A dynamic zooming system may use overlays to display usage information over associated webpages. In one example, a replay manager may zoom-in on particular areas of the webpages to view more specific usage information. In another example, the replay manager may zoom-out the webpages to view more general usage information. The dynamic zooming system may use a first scaled overlay layer to dynamically vary a zoom level of the usage information to match a zoom level for the webpages. The dynamic zooming system also may use a second fixed overlay layer to display other usage information independently of the zoom-level for the webpages.

Abstract: Tools for removing connectors from ports in a network device, and related systems and methods. The tool is elongate with at least one prong at a distal end. The tool includes a very slight width relative to either its length or width, such that it can be inserted into a space adjacent a connector disposed in a port, such as between closely spaced adjacent connectors. The at least one prong is received in an anchor point, such as an opening, in the network device. Pivoting the tool applies a compressive force to a latch of the connector, disengaging the latch from its respective catch on the port, after which it can be removed by pulling it out of the port.

Abstract: A cutter bar is provided for trimming debris away from the wheel-track interface of a tracked vehicle. A pivot attachment is provided wherein a knife having a cutting edge is removably mounted to a bracket by way of fasteners which will shear when a pre-selected force is applied to them. The bracket is mounted to the vehicle structure so that the knife is disposed in close proximity to the drive wheel and endless track of the vehicle. Accordingly, when a piece of tough debris is encountered by the knife edge some of the fasteners will shear and the knife pivots out of the way so that the debris can pass by without causing damage to the wheel or track. The knife and fasteners being readily serviceable with inexpensive parts.
