Abstract: A system and process generate a closed loop test and transactions which removes the variable of lack of data and verifies that each system in the network is indeed moving data instead of simply showing that the software in the network is running. In some embodiments, a unique digital imaging and communications in medicine (DICOM) image is generated. The image may be retrieved from each system in the network so that individual network elements are tested. A new DICOM image may in some embodiments be generated and sent to a first system and retrieved from a second system in the network verifying the integration between the two connected systems. The sum of these tests may automatically monitor all devices in the overall system. The process may be automated so that system administrators may be notified when there is a problem via for example, an electronic dashboard, email or SMS text message.

Abstract: A method and system for utilizing multiple speakers in a portable electronic device is disclosed. The method includes receiving an input at a user interface of a portable electronic device, switching a first and second speaker in a stereo configuration to a mono configuration by routing a first digital to analog converter (DAC) output to both the first and second speaker in response to the input and coupling a third speaker to a second DAC to receive a first audio signal that is responsive to the input. The system includes a first digital to analog converter coupled to a first speaker, a second DAC coupled to a second speaker, and a third speaker. The system further includes switching logic coupled to the first and second DACs. The switching logic is responsive to an input signal provided by a user interface of a portable device. In response to an input signal from the user interface, the switching logic couples the first and second speakers to the first DAC and the third speaker to the second DAC.
