  • Patent number: 6882997
    Abstract: The method termed WaveCluster for mining spatial data. WaveCluster considers spatial data as a multidimensional signals and applies wavelet transforms, a signal-processing technique, to convert the spatial data into the frequency domain. The wavelet transforms produce a transformed space where natural clusters in the data become more distinguishable. The method quantizes a feature space to determine cells of the feature space, assigns objects to the cells, applies a wavelet transform on the quantized feature space to obtain a transformed feature space, finds connected clusters in sub bands at different levels of the transformed feature space, assigns labels to the cells, creates a look-up table, and maps the objects to the clusters. The method can manage spatial data in a two-dimensional feature space. The method also is applicable to a feature space that is made up of an image taken by a satellite.

  • Patent number: 6820290
    Abstract: A movable bathroom-fixture system, comprising bathroom fixtures modified to allow adjustment of their position in a bathroom; and the means to mount said fixtures on bathroom walls so that the fixture placement is adjustable. The modifiable fixtures include a moveable sink fixture, a moveable shower fixture, a moveable wet wall, a height adjustable toilet seat, and drainage tiles. Depending on the size of the bathroom the modifiable fixtures can be slideably and/or removably attached to moveable wall panel units, moveable walls, moveable panels, or fixture interface units.

  • Patent number: 6455831
    Abstract: A foveal image sensor integrated circuit comprising a plurality of CMOS active pixel sensors arranged both within and about a central fovea region of the chip. The pixels in the central fovea region have a smaller size than the pixels arranged in peripheral rings about the central region. A new photocharge normalization scheme and associated circuitry normalizes the output signals from the different size pixels in the array. The pixels are assembled into a multi-resolution rectilinear foveal image sensor chip using a novel access scheme to reduce the number of analog RAM cells needed. Localized spatial resolution declines monotonically with offset from the imager's optical axis, analogous to biological foveal vision.

  • Patent number: 6438905
    Abstract: An energy dissipation apparatus for installation in structural frames to mitigate seismic effects comprises a scissor-jack system of braces with an energy dissipation device such as a viscous, viscoelastic, or hysteretic damper, or an active or semi-active device, connected between opposing pivot joints of the scissor-scissor jack system. The scissor jack system magnifies displacement so that energy is dissipated more effectively by the damper. Open bay, diagonal, and alternative installation arrangements with respect a structural frame are disclosed.

  • Patent number: 6256943
    Abstract: An apparatus for mitigating seismic load imposing an overturning bending moment upon a multi-level structure comprises a tensioned tendon having a first end fixedly connected to one of the levels proximate one side of the structure and a second end fixedly secured to another of the levels proximate an opposite side of the structure, wherein the tendon is oriented in space between its first and second ends along a predetermined curve selected to provide optimum reaction to said load by running the tendon through intermediate story levels at calculated locations. The apparatus further comprises a supplemental system for connecting the second end of the tendon to the structure. The supplemental system preferably includes a mechanical energy dissipating device and a sacrificially yielding fuse element arranged in parallel with the mechanical energy dissipating device.

  • Patent number: 6016689
    Abstract: A sensor having a substrate overlayed with a sol-gel layer, a chemical sensing species deposited upon the sol-gel layer, and a thin film of a second sol-gel layer overlaying and entrapping the species. The effect of this sensor is that the species exhibits a significant portion of its intrinsic function over a period of time. In yet another embodiment of the subject invention, a method is disclosed to form a thin sol-gel layer upon an ambient substrat. This method ensures the integrity, stability and functionality of the chemical sensing species within the sol-gel layers.
