Abstract: The subject matter described herein relates to methods, systems, and computer readable media lor measuring systemic vascular resistance (SVR). In some examples, a method for measuring SVR includes determining, by a computer system coupled to a photoplethysmography (PPG) sensor and a display device, a plurality of wave parameters from a cardiac waveform signal detected by the PPG sensor, wherein the wave parameters include at least a systolic peak amplitude, a diastolic peak amplitude, and a dicrotic notch amplitude. The method includes determining, by the computer system, an SVR value based on the wave parameters. The method includes displaying the SVR value on the display device or other available screen.

Abstract: Techniques for sharing of data by dynamic groups include determining a first digital data set to be shared by devices of members of a first group. One or more entities are determined who are currently members of the first group. At least in part, actions are caused, which result in a change in members of the first group based on input from any of the members of the first group. In some embodiments, techniques include determining a different second digital data set to be shared by devices of members of a second group.

Abstract: A system for the management of computer programs in a computer network environment is presented. A network license server comprises a license server daemon which provides access to a computer program based on information stored in user and license databases. To track software usage, the daemon also maintains a log file which can be accessed by and interfaced with a network administration station. The network license server protects software vendors from unauthorized use of their software while permitting software programs and users to reside anywhere on the network.
