Abstract: Disclosed are systems, including client devices and servers, and methods for creating a collaborative virtual session between client devices, wherein each of the client devices is associable with a coupler agent for interfacing with a communicating entity (such as a person). A client device includes a processor and memory operable to: generate a locally instantiated virtual room; instantiate a virtual representation of a first entity associated with the client device in the locally instantiated virtual room; transmit metadata representative of the first entity to a second client device; receive metadata representative of a second entity associated with the second client device; and, instantiate a virtual representation of the second entity as a function of the received metadata, from a perspective of the first entity, in the locally instantiated virtual room. A server can be utilized to join the client devices in the collaborative virtual session and exchange the metadata.

Abstract: In one general embodiment, a method includes calculating a differential position value based on readback signals from at least two servo readers of a magnetic head reading servo tracks of a magnetic recording tape. The differential position value is compared to a previously-calculated differential position value. An action is performed in response to determining that the difference between the differential position value and the previously-calculated differential position value is in a predefined range. In another general embodiment, an apparatus includes a magnetic head having at least two servo readers, and a controller in communication with the servo readers. The controller is configured to detect a sudden change in a width of a magnetic recording tape based on a differential position value derived from relatively more current servo readback data and a second differential position value derived from relatively older servo readback data.

Abstract: A system is provided having a guide member with features, such as grid and axes, which spatially correlate to tissue with a lesion adjacent the guide member, and a template device upon the tissue aligned with the features having a first aperture over the guide member, and a second aperture over the tissue with the lesion. A microscope captures one or more images of the tissue via the second aperture at one or more locations each spatially correlated with a location selected or being mapped along the guide member in the first aperture. Prior to imaging and template device placement, marks are recorded along the guide member when, as part of a tracing sheet, it is positioned in a folded state over the lesion. When returned to an unfolded state, the guide member once removed from the tracing guide sheet is positioned for use with the template device and microscope.

Abstract: A computer-implemented method includes: determining a reading performance of a head at a commanded lateral reading location; adjusting a location of the head relative to a medium by moving the head in a first lateral direction to an adjusted lateral reading location; determining a reading performance of the head at the adjusted lateral reading location, and determining whether the reading performance at the adjusted lateral reading location is better than the reading performance at the commanded lateral reading location. In response to determining the reading performance is better at the adjusted reading location, the method includes iteratively repeating the adjustment of the location of the head until the reading performance of the head at a current iteration is worse than the reading performance of the head at an immediately previous iteration.

Abstract: A method, according to one embodiment, includes writing a plurality of shingled tracks using an array of writers. The array of readers is repositioned to various locations between first and second positions and data is read from the shingled tracks at the various locations.

The method includes computing, using the read offset point, data describing a lateral writing position to use during writing such that shingled tracks are written in a location specified by a format. As a result, methods according to the present embodiment are able to provide desirable track alignment and reduced readback error rates for data of shingled tracks written to magnetic medium.
