Abstract: A system for modulating air flow in a gas turbine engine is provided. The system may include a seal wall comprising an opening, a seal door configured to slideably engage the seal wall, and an actuator configured to move the seal door over the opening. In various embodiments, the system may include a surface forward of the seal door. The seal door may be configured to seal a passage through the surface and the opening of the seal wall. A track may be disposed under the seal door. The track may comprise cobalt. Rollers may be coupled to the seal door with the rollers on the track. The seal door may comprise a nickel-chromium alloy. A sync ring may be coupled to the seal door. The actuator may be coupled through the sync ring to the seal door.

Abstract: An automatic external defibrillator including: a sensor for detecting when a rescuer is delivering a CPR chest compression to the patient; electrodes for application to the thorax of the patient for delivering a defibrillation shock to the patient and for detecting an ECG signal; defibrillation circuitry for delivering a defibrillation shock to the electrodes; and a processor and associated memory for executing software that controls operation of the defibrillator. The software provides: ECG analysis for analyzing the ECG signal to determine if the cardiac rhythm is shockable; CPR detection for analyzing the output of the sensor to determine when a CPR chest compression has been delivered, and integration of the ECG analysis and CPR detection so that the determination of whether the cardiac rhythm is shockable is based only on time periods of the ECG signal during which there has not been a CPR chest compression delivered.

Abstract: A cardiac resuscitation device that includes a pulse sensor configured to detect pulse information characterizing the cardiac pulse in the patient, an accelerometer configured to detect chest movements of the patient during chest compressions, and memory and processing circuits configured to process the outputs of the pulse sensor and accelerometer to monitor the effect that chest compressions have on the patient's pulse.

Abstract: A computer-implemented method of recording the times of events related to the medical care delivered to patient, and for integrating those times to provide a patient history, including recording a first time of occurrence of a first event, recording first clock information characterizing a first time source from which the first time of occurrence was obtained, recording a second time of occurrence of a second event, recording second clock information characterizing a second time source from which the second time of occurrence was obtained, wherein the first time source and the second time source are independent of one another and not synchronized with one another, transferring recorded data so that the first time of occurrence, first clock information, second time of occurrence, and second clock information are accessible at a computer; and producing a patient history using at least the first and second times of occurrence.

Abstract: An external defibrillator for delivering a defibrillation waveform to a patient. The defibrillator includes chest electrodes for detecting at least one ECG signal on the patient and for delivering the defibrillation waveform to the patient, a defibrillation circuit for shaping and delivering the defibrillation waveform, a pulse sensor for detecting the presence of a cardiac pulse in the patient, wherein the pulse sensor has a pulse signal as its output, and memory and processing circuits for analyzing the pulse signal in conjunction with the ECG signal to determine whether the patient has a pulse.

Abstract: A gripping tool assembly for grip securing an eyelet to a printed circuit board. The gripping tool assembly comprises a flat blade in a blade holder. The blade has a rounded distalmost tip with tapered side edges which extend into semi-circular "curling" portions which segments any barrel of an eyelet pressed thereagainst into curled strips. A conically shaped opening in the holder shapes the non-curled portions of the blade inot biased flanges for gripping any wire inserted into the barrel of the eyelet.

Abstract: A blind fastener of the pull through rivet type having a mandrel disposed in a hollow rivet having a flange end and a forming end, the mandrel has a head disposed adjacent the forming end and adapted to be pulled through the rivet body. The invention being in the mandrel head having a predetermined configuration acting on the forming end of the rivet while being pulled through the rivet body to upset the forming end of the rivet to provide inwardly disposed flanges. Additionally, the mandrel head configuration also upsets the rivet body and the opening in the workpiece enabling the rivet to have optimum torque carry capacity.
