Abstract: Aspects of the subject technology relate to electronic devices that can provide protected use of user-related information to applications, for generating user-specific outputs. The protected access may allow an application to process the user-related information within a processing environment of a processor that is separate from a primary processor of an electronic device. Within that processing environment, the application can utilize the user-related information to generate a user-specific output from the device. However, the application is prevented from extricating the user-related information, and information derived from the user-related information, from that processing environment.

Abstract: In some embodiments, a blood flow sensor device such as a non-invasive cardiac arrest monitor (NICAM) that uses ultrasound to detect blood flow is used to monitor blood flow during cardiopulmonary resuscitation. One or more gating signal generation devices transmit gating signals to a blood flow monitoring computing device. The blood flow monitoring computing device uses the gating signals to determine time periods during which blood flow information generated by the blood flow sensor device is most likely to be accurate. The blood flow monitoring computing device measures blood flow during the time periods. In some embodiments, the blood flow monitoring computing device presents the measured blood flow to a user. In some embodiments, the blood flow monitoring computing device transmits a command to a chest compression device based on the measured blood flow.

Abstract: In a method for calculating, by an estimator, an instantaneous velocity vector {right arrow over (Vu)} of a rail vehicle, the estimator receives measurements from an inertial unit at a fixed point in the vehicle body and determines a mathematical model M of the dynamics of the vehicle moving on a track, the model being dependent on the bias of the inertial unit and installation parameters, a virtual sensor is determined based on the model M, the virtual sensor enabling calculation, from model parameters, two theoretical transverse velocities ?vyc, and ?vzc along axes yc and zc, respectively. An iterative estimator calculates {right arrow over (Vu)}, and includes the virtual sensor, the estimator being configured so the two theoretical transverse velocities are zero regardless of the rail configurations, the estimator enabling correction of the biases of the inertial unit and estimate installation parameters. Auxiliary velocity or distance travelled sensors are not used to calculate {right arrow over (Vu)}.
