Abstract: A computer-implemented method of measuring and updating a software program in a client system, the software program comprising plural functions, the method comprising receiving statistics on the usage of certain functions in the software program in a predetermined time period and generating and issuing an update to the software based on the statistics, characterized by deriving a function mapping table mapping functions of the software program to abbreviations, said mapping being arranged in order of frequency of use of the functions as indicated in previously received statistics, and communicating said table to the client system, where said statistics received from the client system refer to the abbreviations instead of the functions.

Abstract: A PTT monitoring system for measuring arousal and responses to stress or pain during sedation or anesthesia. includes ECG electrodes and a PPG probe connected to a computer via signal conditioning and digitizing hardware. Lead I is typically used as the ECG lead while the PPG probe is typically placed on a finger. The ECG and PPG waveforms are continuously analyzed to update and display a current estimate of the subject's PPT from heart to hand. For each cardiac cycle, fiducial points are identified to indicate the pulse onset time (via QRS detection in the ECG) and pulse arrival time (via the point of steepest ascent in the PPG). The onset and arrival times for each cardiac cycle are paired, and the time difference is the interval estimate for that beat. An artifact post-processor (e.g., trim-mean filtering) excludes unlikely intervals from entering the averaged, current estimate of PTT. Finally, the current PTT estimate is displayed numerically and the trend of PTT is updated every second.
