20150355358 | GENERALIZED SPECTRAL DECOMPOSITION - A method for decomposing a signal includes receiving sampled data. A wavelet is built using the sampled data that includes a plurality of samples. The wavelet includes a number of oscillations per sampling unit, and a length of the wavelet corresponds to the number of oscillations. The wavelet is time-shifted. The wavelet is then scaled such that the samples proximate to one or both ends of the wavelet decay toward zero. The wavelet is also scaled such that an amplitude at a peak frequency of the wavelet, when transformed into a Fourier domain, is substantially unity. | 12-10-2015 |

The user may operate the speed tool to examine the histogram of color or intensity of the pixels or voxels of regions of the model view, and set a speed curve to control how quickly or slowly a cursor or other control may move through or traverse a region, based on the color, intensity, or other value. Regions of interest may be explored more efficiently and accurately. | 05-14-2015 |
20150177917 | TOILET MANAGEMENT SYSTEMS, METHODS, AND TECHNIQUES - Toilet management systems provide information about toilet units. Users, such as visitors and maintenance personnel, may consult an application on their mobile phone, tablet, or webpage to view metrics about a series of toilets, for example in a line of stalls or among multiple portable toilets at a sporting event. The user can determine condition and availability of each toilet, and even reserve the most favorable toilet via a reservation system. The mobile device or webpage can graphically display recommendations to the user, as well as such comparative metrics as the toilet with the longest time since last occupancy, toilet with least cumulative occupants, cumulative time of occupancy, duration of previous visit, cumulative environmental load of previous visits, and qualitative experience of previous toilet visitors. Toilet metrics may be displayed on visual dials, gauges, indicators, pie-chart, bar, bubble, and histogram indicators, numerical indicators, color lights, arrows, sounds, and timeline displays. | 06-25-2015 |

20140191344 | MEMS PROCESS AND DEVICE - A method of fabricating a micro-electrical-mechanical system (MEMS) transducer comprises the steps of forming a membrane on a substrate, and forming a back-volume in the substrate. The step of forming a back-volume in the substrate comprises the steps of forming a first back-volume portion and a second back-volume portion, the first back-volume portion being separated from the second back-volume portion by a step in a sidewall of the back-volume. The cross-sectional area of the second back-volume portion can be made greater than the cross-sectional area of the membrane, thereby enabling the back-volume to be increased without being constrained by the cross-sectional area of the membrane . The back-volume may comprise a third back-volume portion. The third back-volume portion enables the effective diameter of the membrane to be formed more accurately. | 07-10-2014 |
