    摘要: A multiple-cell battery having a built-in controller is disclosed that extends the run time of the battery. The controller may extend the run time of the battery, for example, by converting the cell voltage to an output voltage that is greater than a cut-off voltage of an electronic device, by converting the cell voltage to an output voltage that is less than the nominal voltage of the electrochemical cell of the battery, or by protecting the electrochemical cell from current peaks. The controller may also include a ground bias circuit that provides a virtual ground so that a converter may operate at lower cell voltages. The battery may be a single-cell battery, a universal single-cell battery, a multiple-cell battery or a multiple-cell hybrid battery. The individual cells of the multiple-cell battery may be connected in series or parallel. In addition, the individual cells may have a controller in each cell that is capable of performing one or more functions to extend the run time of the cell.

    摘要: A first embodiment microneedle array is constructed of silicon and silicon dioxide compounds using MEMS technology and standard microfabrication techniques to create hollow cylindrical individual microneedles. The resulting array of microneedles can penetrate with a small pressure through the stratum corneum of skin to either deliver drugs or to facilitate interstitial fluid sampling through the hollow microneedles into the epidermis. The delivery of drugs and sampling of fluids can be performed by way of passive diffusion (time release), instantaneous injection, or iontophoresis. In a second embodiment, an array of hollow (or solid) microneedles is constructed of plastic or some other type of molded or cast material. An electric field may be used to increase transdermal flow rate, and the microneedles can be effectively combined with the application of an electric field between an anode and cathode attached to the skin which causes a low-level electric current. As a drug delivery system, the microneedle array includes electrodes that apply an electric potential to the skin between the electrode locations. One of the electrode assemblies is filled with an ionized drug, and the charged drug molecules move into the body due to the applied electric potential. As a body-fluid sampling system, the microneedle array also includes electrodes to assist in moving fluid from the body into a receiving chamber, and which further includes a bioelectrochemical sensor to measure the concentration of a particular substance.

    摘要: 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. Some of the microstructures are designed with very close-packed microelements, which in some cases have flexible substrates.
