Abstract: A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

Abstract: An aircraft propulsion system includes an engine. The propulsion system further includes an inlet having a forward cowl lip and an aft cowl lip. The forward cowl lip moves between retracted and deployed positions. The forward cowl lip is adjacent to the aft cowl lip when retracted. The forward cowl lip is spaced apart from the aft cowl lip when deployed. The forward cowl lip has a smaller radius of curvature than the aft cowl lip. The propulsion system further includes a controller coupled with the engine and inlet. The controller restricts the maximum thrust commanded position of the engine when the aircraft is on the ground and moving below a predetermined speed. The controller lifts the restriction when the aircraft is moving at at least the predetermined speed. The controller controls the inlet to deploy the cowl lip when the aircraft is on the ground.

Abstract: A gas detector system for detecting gases such as CO.sub.2. Sample air is passed through a critically sized sealed sample chamber in a sample cell. Infrared waves are generated in an insulated heater assembly, and radiate through windows of the sealed sample chamber concurrent with the sample air. The strength and magnitude of the infrared waves is attenuated by the level of gas, such as CO.sub.2, present in the sample air passing through the critically sized sealed sample chamber, and is sensed by a thermopile detector, including a filter for a specific frequency of infrared energy. Electronic circuitry processes the thermopile signal and measures other parameters of the gas detector to provide a signal indicative of the percentage of gas concentration in the air. Extensive use of insulation about and around the thermopile detector electronic circuitry and other components of the detector maximize stability and reliability.
