2 2-1 Chapter 2Theory of Operation Overview At a system level, the PageWriter Trim cardiograph performs acquisition, analysis, printing, storage, and transfer of ECG waveforms and other patient clinical data. The PageWriter Trim cardiograph consists of three major subsystems: „Main controller An Intel StrongArm-base single-board computer (SBC) with extensive I/O facilities, running Windows CE 4.1. The PageWriter Trim application software runs on the main controller, which includes the display and user-input subsystems. „Print controller A Motorola Coldfire-based control circuit, embedded in the main controller board that provides all the real-time management of the printer. The print controller communicates with the main controller through USB. „Patient Interface Module (PIM) An Intel StrongArm-based controller running Windows CE 4.1, coupled with a signal acquisition board employing Philips proprietary mixed-signal ASIC technology for ECG acquisition. The PIM communicates with the main controller through USB. Hardware Logical View Control of the PageWriter Trim cardiograph is provided by application software running on the main control board, interacting with numerous hardware and software subsystems. The following are high-level descriptions of these various subsystems. Main Control Board The main control board contains loader software and the Windows CE kernel image in its internal flash memory (32 MB for PageWriter Trim II, III, Rx; 16 MB for PageWriter Trim I). At system boot, a system RAM test is performed by the loader (onboard RAM is 64 MB), and then the Windows CE kernel loads. When Win CE loads, the application launcher runs, verifying system and executable images before loading the main application. For PageWriter Trim II/III/Rx, all interaction with the operator is through the Ruby300_APP application. For PageWriter Trim I, all interaction with the operator is through the Ruby100_APP application. The application software is stored in internal Flash memory.
Theory of OperationHardware Logical View 2-2PageWriter Trim Cardiograph Service Manual The PageWriter Trim II, III and Rx cardiographs each have an internal ECG archive that consists of a CompactFlash (CF) card installed on the main control board. The number of ECGs that can be stored to this internal memory varies by cardiograph model as shown in the following table. NOTEThe PageWriter Trim I cardiograph does not provide internal storage. Figure 2-1 illustrates the devices and interfaces provided by the main control board. Table 2-1 ECG Storage Capacity Model ECG Storage Capacity * *. ECG storage capacity is not dependent upon the size of the in- ternal CF card. The ECG storage capacity is controlled by the cardiograph software application.

WARNINGDo not connect the modem card to a phone line when the cardiograph is connected to a patient. High Level ECG Data Flow and Storage General ECG data flow begins with acquisition by the Patient Interface Module (PIM) from electrodes placed on a patient. Data is streamed real-time to the main control board, where it is received into the application buffers in RAM. These buffers are used to present the signal data on the real-time screen. When the user initiates an Auto ECG print, the corresponding 10- second segments of the signal data are then copied to the temporary ECG storage memory in RAM. These 10-second segments are named ECG reports that can be previewed and printed. In the case of Auto mode, the ECG report may be configured to automatically print. An ECG report contains signal data, analysis information, patient demographics, and acquisition information, along with operator and device information. See the XML Utility Suite Instructions for Use available on the Philips InCenter site ( incenter.medical.philips.com) for a complete description of the contents of the ECG data record. For information on using the InCenter site, see page 1-26. If the Automatic Save After Print option is enabled on the cardiograph, the ECG report is saved in XML format to the internal main archive. This archive is non-volatile and resides on the internal CompactFlash (CF) card. Index files with a CDB extension are also maintained in this archive. From the internal main archive, the ECG XML data format files can be copied, deleted, previewed, printed, and transferred to other devices. The internal main archive cannot receive ECG XML files from external devices. Retrieved ECG file storage is limited to the internal remote archive. NOTEPageWriter Trim-generated ECG XML files comply with the Philips Medical Systems ECG XML Schema version. They incorporate an embedded CRC32 value, which is used to ensure the data integrity of the file.
