Abstract: Particular embodiments may receive signals periodically detected by a mobile device and transmitted by multiple fixed-location signal sources within an environment, wherein the mobile computing device includes at least a camera. A spatial distribution of signal strengths is determined based on the detected signals, and relative positions of the mobile computing device are identified using the detected spatial distribution of signal strengths. The system may receive and analyze the images of the environment captured by the camera and calibrate the relative positions using the image analysis results. A map of spatial distribution of signal strengths is created by correlating the spatial distribution of signal strengths with the calibrated relative positions.

Abstract: A programming element is provided that defines model attributes in response to mode change events in a graphical modeling environment. Such definition may involve any signal attribute such as dimensions, data types, complexity and sample times. Events that trigger definition of model attributes may be explicit signaling events generated by other elements, elements within the block diagram programming environment, and elements external from the environment. Implicit events may also trigger definition of model attributes, such as a change of attribute in an input signal.

Abstract: A zeolite composite membrane apparatus and method for preparing a novel continuous zeolite composite membrane. The method described results in formation of a thin polycrystalline continuous zeolite layer on the inner wall of a substrate container. The container may be a cylinder. After calcination, the zeolite composite membrane shows high permeability and high selectivity for single gas and for vapor/gas mixtures. The zeolite composite membrane formed has improved separation characteristics of shape selectivity and selective adsorption. The geometry of the membrane provides a high permeation area to volume ratio. The membrane is useful for high temperature gas separations and for membrane reactor applications.
