Abstract: Improved microneedle arrays are provided having a sufficiently large separation distance between each of the individual microneedles to ensure penetration of the skin while having a sufficiently small separation distance to provide high transdermal transport rates. A very useful range of separation distances between microneedles is in the range of 100–300 microns, and more preferably in the range of 100–200 microns. The outer diameter and microneedle length is also very important, and in combination with the separation distance will be crucial as to whether or not the microneedles will actually penetrate the stratum corneum of skin. For circular microneedles, a useful outer diameter range is from 20–100 microns, and more preferably in the range of 20–50 microns.

Abstract: An improved method and apparatus is provided as a system to enhance skin appearance and health, in which skin is cleaned (or exfoliated) and conditioned by use of microelements affixed to a base element or hand-held patch. The dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate those skin cells, along with other foreign substances, into areas between the microelements. In addition, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of accumulated skin cells represents a self-limiting maximum quantity that cannot be substantially exceeded regardless of the number of attempts by a user to re-use the microstructure apparatus.

Abstract: A method for determining the probability of observing an event. The event may occur either alone or in combination with one or more other events. The method may be non-combinatorial in that it does not require a separate calculation for each simultaneously occurring event, thereby significantly reducing computation time for complex systems having multiple events. Further, the method may be numerically reversed to calculate the probability of an event occurring based upon the number of observations. The method is particularly useful for predicting availability, component failure, or the possibility of a false start in production systems.
Abstract: A method and device for applying sheet material, such as wallpaper, to a substrate. The applicator is bi-positionable, having a first position where the sheet material is spaced apart from the substrate and a second position where the sheet material contact the substrate. Additionally or alternatively, the applicator may be provided with a control bar. In the first position, the control bar contacts a portion of the sheet material such as its free end. This minimizes the chance of the sheet material prematurely contacting the substrate. In the second position, the sheet material is disengaged from the control bar for application to the substrate. The applicator and sheet material may be provided together in a kit.

Obstructions include objects which may impair the or impede the mobility of the robot, as well as transitions from carpeted surfaces to hard surfaces, transitions from hard surfaces to carpet, or transitions between other types of flooring. The system includes a plow which may move underneath the obstruction, The obstruction may the be brushed aside, or rise to an elevation detectable by the robot. Upon detection, the robot may change its direction of movement or stop moving altogether.
Abstract: An apparatus and method for molding three-dimensional articles having interstitials. The article has elongate elements and interstitials between the elongate elements. The interstitials may extend entirely through the article, or intercept only the periphery of the article. The article may be formed by injection molding, using two or more mold segments, each having elongate members. The mold segments are separated from each other in a separation direction. The separation direction is parallel to the elongate members of the mold segments and/or the elongate elements of the article. The method and apparatus according to the present invention is useful for making a static mixer, heat exchanger or similar article.
Abstract: The present invention relates to a horizontally movable and downwardly biased appendage that extends laterally from a surface treating apparatus, such as a robotic floor cleaner.
The robotic floor cleaner and/or appendage may use disposable cleaning sheets, such as dust clothes, wipes, sheet-brushes, and the like, to clean under objects or into corners but does not substantially interfere with the rotation of the surface treating apparatus about its axis when it is adjacent to encountered obstacles. The appendage can extend under low hanging obstructions to remove dirt, and reach into corners innavigable or unreachable by the robotic floor cleaner.
Abstract: An extrusion/coating die. The die has an internal cavity and one or more static mixers in the die cavity. The static mixer fills the die cavity at its respective cross section. The die may also have one or more auxiliary inlets for separately admitting material/energy to the die.
