Abstract: A method and system for assessing alarm events generated in a physiological monitoring system is described. The method identifies one or more qualitative measures associated with the generation of the alarm event. The one or more qualitative measures can include a calculated trajectory of the monitored physiological parameter, the calculated time between alarm events and the duration of the current alarm event. Based upon the qualitative measures, the method calculates a clinical relevancy score for the alarm event. The alarm event, each of the qualitative measures and the clinical relevancy score are presented on a display panel. The method and system can generate an urgent alarm based on the calculated relevancy score. The system includes a processor that calculates the clinical relevancy score based on qualitative measures and algorithms entered into the processor.

Abstract: Phosphor particles, methods for their use to produce fluorescent lamps, and fluorescent lamps that make use of such particles. Such a phosphor particle has a core surrounded by a shell, and the shell contains GdMgB5O10 doped (activated) with at least terbium ions as a rare earth-containing phosphor composition that absorbs ultraviolet photons to emit green-spectrum light. The core is formed of a mineral material that is chemically compatible with the rare earth-containing phosphor composition of the shell, but does not contain intentional additions of terbium.

Abstract: An ultrasonic diagnostic device is provided. The device includes a transmission control unit configured to generate a first ultrasonic wave and a second ultrasonic wave for detecting movement of a physical object in a biological tissue, wherein values of transmission parameters of repetitively transmitted first ultrasonic waves that are relevant to movement of the physical object are different from one another. The device further includes a decision unit configured to determine presence or absence of movement of the physical object, and a display image control unit configured to generate an image according to the value of the transmission parameter of the first ultrasonic wave in a case where the decision unit decides that movement is present, or a predetermined value in a case where the decision unit decides that movement is absent and the value of the transmission parameter of first ultrasonic wave has reached the predetermined value.

Application number: 20150173723
Abstract: A tracking system that includes a sensor and emitter is calibrated, and a tracked position and orientation of a surgical instrument is determined based at least in part on tracking information emitted by the emitter and detected by the sensor. An ultrasound system performs an ultrasound scan to acquire ultrasound scan data including the surgical instrument. The ultrasound system determines a scanned position and orientation of the surgical instrument based on the ultrasound scan data. The ultrasound system compares the tracked position and orientation with the scanned position and orientation to determine a calibration error. If the calibration error exceeds a threshold, the ultrasound system may (1) prompt a user to repeat the tracking system calibration step, (2) automatically recalibrate the tracking system and/or the ultrasound system, or (3) provide a user option for proceeding with automatic recalibration of the tracking system and/or the ultrasound system.
