The loudspeaker system includes means for modifying the radiating or polar pattern associated with each radiating lobe; wherein the system is arranged such that a listening position substantially equidistant from the first and second arrays is exposed to radiation from the second lobes or from the first lobes and a listening position not substantially equidistant from the first and second arrays is exposed to radiation from both the first lobe of one array and the second lobe of the other array such that substantially all positions in the listening zone receive sound radiation from the first and second arrays with substantially equal arrival times. | 06-21-2012 |
20120163607 | MATRIX DECODER FOR SURROUND SOUND - A decoder and decoding method for use in surround sound system wherein at least four audio input signals representing an original sound field are encoded into two channel signals and said encoded signals are decoded into at least four audio output signals corresponding to the four audio input signals and have an amplitude ratio and a phase relationship. The decoder and method including means for: compensating the said encoded signals for variations in perceived loudness relative to frequency associated with the encoded two channel signals due to non linearity in human hearing response at least at some frequencies; producing steering signals in responsive to the phase relationship of the said compensated signals; decoding said encoded signals to produce audio output signals corresponding to audio input signals by varying at least the amplitude ratio of said encoded signals contained in each of the output signals in response to said steering signals. | 06-28-2012 |

20090132332 | COMPUTER IMPLEMENTED SCHEDULING SYSTEMS AND ASSOCIATED METHODS - Computer implemented scheduling systems and associated methods are disclosed. In one embodiment, a method for deriving a roster includes generating a roster within the operational constraint by assigning a plurality of workers to a plurality of individual shifts; calculating a value of the operational outcome based on the assigned shifts in the roster; calculating an overall fatigue value for the assigned individual workers based on the assigned shifts in the roster; and determining whether the generated roster is optimized based on the calculated value of the operational outcome and the overall fatigue value of the workers. | 05-21-2009 |
20120191425 | SYSTEMS AND METHODS FOR INDIVIDUALIZED ALERTNESS PREDICTIONS - Systems and methods are provided for generating individualized) predictions of alertness or performance for human subjects. Alertness or performance predictions may be individualized to incorporate a subject's individual traits and/or individual states. These individual traits and/or individual states (or parameters which represent these individual traits and/or individual states) may be represented by random variables in a mathematical model of human alertness. The mathematical model and/or prediction techniques may incorporate effects of the subject's sleep timing, the subject's intake of biologically active agents (e.g. caffeine) and/or the subject's circadian rhythms. The mathematical model and/or prediction techniques may incorporate feedback from the subject's measured alertness and/or performance. | 07-26-2012 |
20130304326 | ALERTNESS MONITORING SYSTEMS AND ASSOCIATED METHODS - Embodiments of driver alertness monitoring systems, devices, and associated methods based on steering variability and/or lane variability are described herein. In one embodiment, a method for detecting alertness of a driver operating a vehicle includes recording a steering position of the vehicle with a steering sensor and transmitting the recorded steering position to a processor. With the processor, the method also includes deriving a steering variability based on the recorded steering position of the vehicle over time, calculating a lane variability based on the derived steering variability and a transfer function of the vehicle, and estimating an alertness of the driver based on both the derived steering variability and the calculated lane variability. | 11-14-2013 |

20150267500 | SEALING APPARATUS AND METHOD - Disclosed is a sealing apparatus for use in establishing a seal around a tubular, and a method of use of the sealing apparatus. The apparatus includes a deployable sealing arrangement which can be engaged with an internal wall of a tubular so as to form a sealed area. The wall of the tubular may then be perforated within the sealed area, and sealant injected through the perforation. Accordingly, the apparatus permits both perforation and sealant injection to occur within a common sealed area, assisting to ensure that the injected sealant will always be appropriately aligned with the established perforation, thus maximising the injected volume of available sealant. Isolation of the sealed area from fluid inside the tubular also prevents or restricts contamination of the inside of the tubular with sealant or fluids around the tubular, and sealant cannot be washed away by fluid within the tubular. | 09-24-2015 |
