Abstract: A persistent storage device includes a filesystem having a data exclusion list and a protection system stored thereon. The data exclusions list identifies excluded filesystem folders. A processor is programmed to create a canary file in at least one of the excluded filesystem folders. The processor intercepts input/output (I/O) events, each being directed to a respective target filesystem object. The processor stores system event metadata associated with each of the I/O events. The system event metadata includes a file identifier of the respective target filesystem object. The processor creates a backup copy for each respective target filesystem object. The processor releases the I/O events to be performed on the respective target filesystem objects. In addition, the processor determines, based on at least one file identifier, that one of the respective target filesystem objects is the canary file, and replaces each respective target filesystem object with its respective backup copy.

Abstract: Disclosed are systems and methods for providing virtual reality guidance to a user performing a procedure on a virtual instance of an item. The systems and methods may be used in training the user to perform the procedure on a physical instance of the item.

Abstract: A computing system includes a memory device, a persistent storage device, and a processor. The persistent storage device includes a filesystem having filesystem objects and a protection system stored thereon. The protection system includes a filesystem minifilter driver and a protection service. The minifilter driver intercepts an input/output (I/O) event directed to a target filesystem object and extracts system event metadata from the I/O event. The system event metadata includes an identifier of the target filesystem object. The system event metadata is transmitted to the protection service and recorded in a record file. A backup copy of the target filesystem object created. The I/O event is released after recordation of the system event metadata and creation of the backup copy, thereby enabling the I/O event to be performed on the target filesystem object. During a system restore operation, the target filesystem object is replaced with the backup copy.

Abstract: A method of using a laryngoscope guide including a guiding conduit for advancing an introducer. The method can be used to intubate a subject by positioning the laryngoscope guide in an airway; advancing the introducer in the conduit until an end of the introducer enters the glottis, while viewing images of the introducer end; removing the laryngoscope guide with the guide conduit from the introducer and from the airway; guiding a tube with the introducer until an end of the tube enters the glottis; and removing the introducer from the tube with the end of the tube remaining in the glottis, and in particular, in the trachea, to establish an airway. The guide and method can enable a healthcare professional to intubate a subject where neck mobility is an issue, where an airway is difficult, and/or where a subject is obese.

Abstract: A laryngoscope guide including a guide conduit for advancing an introducer. The guide can house an imaging system having a field of view and an optical axis. The guide can include a distal tip and a first blade plane that bisects the distal tip and/or the blade. The guide conduit can define an advancement axis projecting into the field of view, the advancement axis aligned to traverse and/or intersect at least one of the first blade plane and the optical axis. The orientation of the advancement axis relative to the first blade plane and/or optical axis can assist in viewing, aligning and optionally steering the introducer with the guide into a preselected location in a subject, such as a glottis or a trachea, to optionally establish an airway. The guide is suitable for use where neck mobility is an issue, an airway is difficult, or a subject is obese.
