摘要:
Methods provide for measuring moisture content of skin, such as the scalp. More particularly, the present invention is directed to a method comprising the steps of: (a) providing a means for measuring skin moisture content; (b) using the means for measuring skin moisture content to obtain at least one measured moisture content value for the skin; (c) correlating the measured moisture content value to a skin moisture value for the skin; and (d) using the skin moisture value to assess health state of the skin.

An improved method is provided 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. For the microstructure used in the improved method, the dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate and retain those skin cells, along with other foreign substances, into areas between the microelements. In another embodiment of the improved method, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of skin cells accumulated using the improved method 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 associated with the improved method. Some of the microelement shapes are purposefully designed with distal ends that exhibit sharp edges rather than sharp tips to reduce skin irritation resulting from use of the improved method.

A microvalve for controlling fluid flow, including a body portion having a plurality of spaced openings formed therein, a shutter located adjacent to and substantially parallel with the body portion having a plurality of spaced openings formed therein, a drive mechanism for causing the shutter to move laterally with respect to the body portion so that the spaced openings of the shutter are brought into and out of alignment with the spaced openings of the body portion, wherein the microvalve is in an open position and a closed position, respectively, and, a latching mechanism for preventing the shutter from moving laterally with respect to the body portion.

An improved method and apparatus is provided as a system to deliver a composition, preferably a medical or pharmaceutical composition or active, through the stratum corneum of skin, without introducing bleeding or damage to tissue, and absent pain or other trauma. The dimensions and shapes of the microelements are controlled so as to control the penetration depth into the skin. The microelements can be “hollow” such that passageways are created therethrough to allow the composition to flow from a chamber, through the microelements, and into the skin. Alternatively, the microelements can be “solid,” and the composition is applied directly to the skin just before or just after the microelements are applied to the skin surface to create the openings in the stratum corneum.

摘要:
A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Also, the dynamic control accommodates the advantages of using ultra-capacitors in the charge pump. The power converter is capable of operating with a sub-one volt input voltage incorporating low-threshold, low on-resistance power MOSFET switches in the switch matrix of the charge pump. A progressive start-up circuit further allows the power converter to start from a discharged state even with a sub-one volt input voltage.
