20130118461 | NOx FEEDBACK FOR COMBUSTION CONTROL - A method for controlling combustion in an engine is provided. The method comprises under a first condition, adjusting an EGR amount of a total cylinder charge in response to engine out NOx levels being below a first threshold. In this way, NOx levels may be used as feedback to control combustion stability. | 05-16-2013 |
20140102077 | METHODS AND SYSTEMS FOR AMMONIA SLIP DETECTION - Various systems and methods are described for detecting ammonia slip. In one example method, an amount of exhaust gas recirculation is reduced when output from an exhaust gas sensor indicates an increase in nitrogen oxide above a threshold amount. When the sensor output increases above a second threshold while the exhaust gas recirculation is reduced, the sensor output is allocated to nitrogen oxide; and when the sensor output does not increase above a second threshold while the exhaust gas recirculation is reduced, the sensor output is allocated to ammonia. | 04-17-2014 |
20140298778 | ENHANCED REAL-TIME AMMONIA SLIP DETECTION - Various systems and methods are described for detecting ammonia slip. In one example method, an exhaust system with two NOx sensors uses transient responses of the NOx sensors to allocate tailpipe NOx sensor output to NOx and NH | 10-09-2014 |

20090039535 | Extended Wear Ophthalmic Lens - A method for making a silicone hydrogel contact lens is provided. In one embodiment, a prepolymer mixture is polymerized in a lens mold in an atmosphere having less than about ppm oxygen to form a silicone hydrogel contact lens suitable for extended wear as characterized by producing less than 10% corneal swelling after a period of continuous wear of 7 days including normal sleep periods. In one embodiment, the prepolymer mixture comprises at least one oxyperm material containing hydrophilic groups, wherein the at least one oxyperm material is a siloxane-containing macromer or monomer, at least one ionperm material, and a cross-linking agent. In certain embodiments, the polymerization of the prepolymer mixture may be carried out in an atmosphere having less than about 1000 ppm oxygen. | 02-12-2009 |
20090046242 | Extended Wear Ophthalmic Lens - An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. In one embodiment, an opthalmic lens is a copolymerization product of at least one oxyperm, at least one ionoperm, and a crosslinker. In one embodiment, a lens has a tensile modulus of less than about 3.0 MPa, yet in another embodiment, the tensile modulus is between about 0.5 to about 1.5 MPa. | 02-19-2009 |
20100238398 | Extended Wear Ophthalmic Lens - An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. In one embodiment, an opthalmic lens is a copolymerization product of at least one oxyperm, at least one ionoperm, and a crosslinker. In one embodiment, a lens has a tensile modulus of less than about 3.0 MPa, yet in another embodiment, the tensile modulus is between about 0.5 to about 1.5 MPa. | 09-23-2010 |
20140022507 | Extended Wear Ophthalmic Lens - A method for making a silicone hydrogel contact lens is provided. In one embodiment, a prepolymer mixture is polymerized in a lens mold in an atmosphere having less than about 10000 ppm oxygen to form a silicone hydrogel contact lens suitable for extended wear as characterized by producing less than 10% corneal swelling after a period of continuous wear of 7 days including normal sleep periods. In one embodiment, the prepolymer mixture comprises at least one oxyperm material containing hydrophilic groups, wherein the at least one oxyperm material is a siloxane-containing macromer or monomer, at least one ionperm material, and a cross-linking agent.

20150086954 | Adding Sounds to Simulated Ultrasound Examinations - A system for performing audio-enhanced, simulated ultrasound examinations may generally include an ultrasound simulation device having at least one processor and associated memory. The memory may store pre-recorded audio-enhanced ultrasound data for at least one internal organ. The audio-enhanced ultrasound data may include a moving ultrasound image of the at least one internal organ along with synced audio data associated with auscultatory sounds generated by the at least one internal organ depicted within the moving ultrasound image. In addition, the system may include a display and a speaker coupled to the ultrasound simulation device. The display may be configured to display the moving ultrasound image as a trainee is performing the simulated ultrasound examination. The speaker may be configured to broadcast the synced audio data simultaneously with the display of the moving ultrasound image. | 03-26-2015 |
20150086959 | Ultrasound Loop Control - A method for conducting ultrasonography training using ultrasound loop control may generally include providing for display a moving ultrasound image of an internal body part, wherein the moving ultrasound image is associated with an image frame loop including a plurality of individual image frames. The method may also include receiving an initial input from a user associated with stopping the moving ultrasound image at a current image frame of the image frame loop, receiving a second input associated with cycling forward or backwards through the image frame loop in order to provide additional image frames of the image frame loop for display to the user and receiving a third input associated with a submission of one of the image frames as a selected image frame. | 03-26-2015 |
