20100106105 | Microneedle Structure And Production Method Therefor - A method for processing a wafer to form a plurality of hollow microneedles projecting from a substrate includes forming, by use of a dry etching process, a number of groups of recessed features, each including at least one slot deployed to form an open shape having an included area and at least one hole located within the included area. The internal surfaces of the holes and the slots are then coated with a protective layer. An anisotropic wet etching process is then performed in such a manner as to remove material from outside the included areas while leaving a projecting feature within each of the included areas. The protective layer is then removed to reveal the microneedles. | 04-29-2010 |
20100224590 | METHOD FOR PRODUCING MICRONEEDLE STRUCTURES EMPLOYING ONE-SIDED PROCESSING - A method for forming a hollow microneedle structure includes processing the front side of a wafer to form at least one microneedle projecting from a substrate and a through-bore passing through the microneedle and through a thickness of the substrate. An entire length of the through-bore is formed by a dry etching process performed from the front side of the wafer. Most preferably, upright surfaces of the microneedle structure and the through bore of the structure are formed by dry etching performed via a single mask with differing depths obtained by harnessing aspect ratio limitations of the dry etching process. | 09-09-2010 |

20090307117 | Utility services payment system, methods and apparatus - The invention provides methods, systems and apparatus for combining aspects of a prepay and post pay utility service billing arrangement. When a customer enrolls in the program with the system, utility service is initiated and a first bill is generated and transmitted; the amount of the first bill is an estimated amount of charges for the service to be provided during a first period. In subsequent billing periods, subsequent bills are generated and transmitted and each includes an estimated amount of charges for the subsequent period as well as a difference between actual and estimated charges for the service during the previous billing period, less any payments received from the customer. Service may be terminated if the customer withdraws from the program, if the customer fails to make timely payments, or for other reasons. If service is terminated, a final bill may be generated and transmitted based on actual charges, net of any amounts | 12-10-2009 |
