Abstract: An aircraft emergency parachute deployment system (AEPDS) is disclosed. The AEPDS includes a parachute assembly coupled with an aircraft, a ballistic rocket assembly coupled to a top portion of the parachute assembly by a lanyard, an actuator for initiating launch of the ballistic rocket; and a control module configured to receive aircraft orientation measurements and controlling launch of the rocket when the spatial orientation the aircraft is within a pre-selected range of values.

Abstract: There is provided a data storage system comprising a power supply module, a plurality of serially connected storage enclosures, where a first storage enclosure of the plurality of serially connected storage enclosures is connected to the power supply module, and a power management module connected to the power supply module. A given storage enclosure includes at least one disk storage. The power management module is configured to selectively cause the power supply module to provide electric power to activate the first storage enclosure. The power management module is further configured to selectively cause the power supply module to provide electric power to activate a second storage enclosure, where the second storage enclosure is connected downstream from the first storage enclosure, and the second storage enclosure is configured to selectively receive power from the power supply module in response to the first storage enclosure being active.

Abstract: Respiratory rate can be calculated from an acoustic input signal using time domain and frequency domain techniques. Confidence in the calculated respiratory rate can also be calculated using time domain and frequency domain techniques. Overall respiratory rate and confidence values can be obtained from the time and frequency domain calculations. The overall respiratory rate and confidence values can be output for presentation to a clinician.

Abstract: A pulmonary artery pressure estimator attaches a plurality of acoustic sensors to a patient so as to measure a second heart sound. The sensors are arranged so that an A2 component of the second heart sound is maximized from at least one of the sensors and a P2 component is maximized from at least another one of the sensors. Electrodes are also attached to the patient so as to measure a cardiac interval. A splitting interval is derived from the A2 and P2 components, which is normalized by the cardiac interval. The normalized splitting interval provides an estimation of the pulmonary artery pressure (PAP).

Abstract: A method and apparatus for estimating a location of pulmonary and aortic components of second heart sounds of a patient over an interval. The method comprises the steps of producing an electronic representation of heart sounds of the patient over the interval, identifying at least one second heart sound in the interval using the electronic representation, for each identified second heart sound generating an estimated value for a location of the aortic component and the pulmonary component. There is also included a method for using the estimated location of the aortic component and the pulmonary component for estimation of the blood pressure in the pulmonary artery of a patient.

Abstract: A dual system for ballistic deployment of a parachute (40) caused by explosion of a powder charge (54) to propel a projectile (52) away from an air vehicle, pulling the parachute (40) away from the air vehicle and allowing the parachute to inflate free of the air vehicle. The powder charge (54) is exploded alternatively by the pilot pulling a pull handle (12) to send an igniting current to fire cap (55), or by the pilot pulling handle (70) to activate a spring driven firing pin (80) to fire cap (82); the firing of cap (55) or the firing of cap (82) will explode the powder charge (54).
