US Classification:

242188

Abstract:

A magnetic tape recording and reproducing system in which a light reflective marker is on each reel of tape and has a feedback circuit connected between the light sensor and the source of light for controlling the intensity of the source to maintain the output substantially constant, notwithstanding changes of reflectivity of the tape or gradual changes of efficiency of the source of light. The feedback circuit provides improved detection of the passage of the reflective marker past the sensor.

Abstract:

An embodiment includes executing a discovery pattern for the certificate authority, where the discovery pattern contains instructions for obtaining one or more digital certificates from the certificate authority; obtaining, from the certificate authority, a representation of a digital certificate acquired by a managed network from the certificate authority; storing, in a first set of mappings, a first new mapping between the certificate authority and the digital certificate; receiving, from a computing device disposed with the managed network, an indication that the digital certificate is installed on the computing device;, storing, in a second set of mappings, a second new mapping between the digital certificate and the computing device; determining that the digital certificate is expired; and storing, in a third set of mappings, a third new mapping between the digital certificate and a critical status indicator.
