摘要:
An entertainment system for use with a magnetic resonance imaging (MRI) device that includes video glasses and headphones. A Faraday shield encloses the entertainment system to reduce adequately RF signals from entering or leaving the entertainment system. The entertainment system may have non-ferromagnetic RF low-pass filters between parts of the system, such as the control unit and the video glasses, to reduce higher RF signals from entering or leaving those parts. To replace the battery and or entertainment media, a person opens the entertainment system's Faraday shield when not MRI imaging or outside the MRI magnet room. The door has an Faraday shield overlapping the system Faraday shield and making low resistance RF contact. The entertainment system has a minimal amount of ferromagnetic material so that it may operate within the high magnetic field of the MRI magnet bore with minimal performance degradation. The entertainment system uses non-ferromagnetic speakers in the headphone. Passive ear protection and noise cancellation reduce the loud noise of the MRI system heard by the patient to a level where the patient can hear the entertainment. The entertainment system includes a charger for the rechargeable batteries.

One method for implementing a solution design methodology includes receiving a request to evaluate a value chain associated with an enterprise. The value chain comprises activities. The enterprise is queried for information associated with the activities. A current maturity level of the value chain is identified based, at least in part, on the information. A process model is implemented for increasing the current maturity level.

A method for controlling data flow to a pair of storage devices includes receiving at least one new entry to store in a first storage device or a second storage device in the pair of storage devices and determining a number of entries made to the first and second storage devices out of the at least one new entry. The method also includes calculating a difference between available space in the first storage device and the second storage device, and calculating a number of credits used by the at least one new entry based on the numbers of entries to the first and second storage devices and on the difference in available space.
