The systems and methods include presenting to a user a graphical user interface having printing options for printing the document, where the graphical user interface has an input for receiving an indication by the user that the user is willing to share the hard copy of the document; presenting to the user options for defining characteristics of the hard copy of the document in response to receiving the indication; and publishing at least one of the defined characteristics within a profile page of the user.
Remote environmental and condition monitoring system
The present disclosure relates to systems and processes for environmental and condition monitoring of containerized assets. One illustrative system includes containers that are configured to enclose assets that are potentially hazardous and/or potentially sensitive to electromagnetic (EM)/radio frequency (RF) radiation or emissions. The assets may also be sensitive to various environmental conditions such as temperature, humidity, shock and vibration. An exemplary system uses sensors to measure and track these environmental conditions inside a container for up to multiple years. An illustrative system may also use sensors to measure attributes of the asset. An illustrative system is configured to archive and report on the collected data. An illustrative system includes the ability to issue a warning when an asset may have been compromised. Additionally, the collected data may be used in predictive life analyses. More particularly, the collected data may be analyzed and compared to thresholds for container assets to reach deductive or inductive conclusions about the probability of damage, maintenance needs, or replacement needs.
Data centers task mapping
A data center management system may include a processor coupled to a network. The network may be further coupled to a primary data center and a secondary data center located at a physical location remote from the primary data center. The processor may be adapted to execute computer implemented instructions to determine a first transition point for the primary data center with respect to a secondary data center on the basis of one or more financial indicators, transfer one or more data center tasks from the primary data center to the secondary data center at substantially the first transition point, and execute the one or more transferred data center tasks at the secondary data center.
Method and system for distributing electronic tickets with visual display
This invention discloses a novel system and method for distributing electronic ticketing such that the ticket is verified at the entrance to venues by means of an animation or other human perceptible verifying visual object that is selected by the venue for the specific event. This removes the need to use a bar-code scanner on an LCD display of a cell phone or other device and speeds up the rate at which human ticket takers can verify ticket holders. The system also can permit ticket purchase verification in the absence of a network connection during verfication.
