Abstract: A process includes, responsive to a primary power source being enabled, receiving, from a real time clock (RTC) device of a computer platform, an indication of a first time. Responsive to the primary power source being enabled, the process includes storing first data in a first non-volatile storage of the computer platform representing a snapshot of the first time and repeatedly updating the snapshot to cause the snapshot to track the first time. Responsive to the primary power source being disabled to begin a power outage, the process includes providing, by a timer of the computer platform powered by a secondary power source, a timer output that represents an accumulated time that corresponds to the power outage. The process includes restoring a state of the RTC device responsive to the primary power source being reenabled to end the power outage.

Abstract: A process includes performing actions responsive to secondary power when primary power for a computer platform is unavailable. The actions include providing, by a timer of a computer platform, a timer output that is associated with a first time domain and corresponds to an accumulated time that primary power is unavailable. Moreover, these actions include using secondary power to detect tampering with the computer platform, and responsive to detecting the tampering, reading the timer output to provide a first timestamp that represents a time of detection of the tampering. The process further includes actions which are performed responsive to primary power being subsequently available. These actions include reading data from a non-volatile storage of the computer platform. The data represents a snapshot of a real time clock (RTC) device time that is provided by an RTC device that is powered by the primary power and corresponds to a second time domain.

Abstract: Compositions and methods for separating a sample of whole blood or bone marrow aspirate into a fraction rich in at least one of platelets and pluripotent cells are provided. A sample of whole blood can be centrifuged in a collection tube comprising a separator substance formulated to settle between the PRP fraction and the at least one other fraction. Preferably, centrifugation is completed without substantial activation of platelets.
