摘要:
Osteogenesis and osseointegration promotion and maintenance devices for osseous implants include an implant member having a first electrode, an inlaid second electrode positioned on the member so that it is electrically isolated from and substantially flush with the member surface, and an electrical stimulation mechanism preferably located at the member and operative to provide electrical stimulation signals to endosseous tissue surrounding the implant through the first and second electrodes. The first electrode may be the member itself or a second inlaid electrode. The implant is thus electrically functionalized for osteogenesis and osseointgration acceleration. The device is applicable to both non-dental and dental implants. In all embodiments, the use of inlaid electrode(s) enables the general appearance, external surface and mechanical integrity of the implant to be left essentially unchanged.

Apparatus and method for obtaining a plurality of spectral images of a source object in a snapshot using comprising two-dimensional compressed sensing data cube reconstruction (2D CS-SCR) applied to a dispersed-diffused snapshot image. In some embodiments, the snapshot image is obtained through a RIP diffuser. In some embodiments, a randomizer is used to further randomized the dispersed-diffused snapshot image. The 2D CS-SCR includes applying a 2D framelet transform separately to arrays representing different wavebands of spectral cube data derived from the snapshot image. The application of the 2D framelet transform separately to the arrays representing the different wavebands includes application of direct and inverse 2D framelet transforms to the arrays. In some embodiments, the direct and inverse framelet transforms are included in a split Bregman iteration.

Methods for forming three-layer thin-film battery (TFB) structures by sequential electrophoretic deposition (EPD) on a single conductive substrate. The TFBs may be two- dimensional or three-dimensional. The sequential EPD includes EPD of a first battery electrode followed by EPD of a porous separator on the first electrode and by EPD of a second battery electrode on the porous separator. In some embodiments of a Li or Li-ion TFB, the separator includes a Li ion conducting solid. In some embodiments of a Li or Li-ion TFB, the separator includes an inorganic porous solid rendered ionically conductive by impregnation with a liquid or polymer. In some embodiments, the TFBs are coated and sealed with an EPDd PEEK layer.
摘要:
Monochromatic cameras and methods for using such cameras to obtain a still or video color image of an object or scene. The image sensor of such cameras is clear, without a color filter array. A diffused-dispersed and optionally randomized image of the object or scene obtained at the image sensor is processed directly into a number R
