  • Network node and method for managing power of Cell Reference Symbols
    Patent number: 11304153
    Abstract: A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

  • TRANSDERMAL THERAPEUTIC SYSTEM FOR DISPENSING SCOPOLAMINE WITHOUT A MEMBRANE
    Publication number: 20210290560
    Abstract: The present invention relates to a transdermal therapeutic system without a release-determining membrane for delivering scopolamine, comprising a skin contact layer, an active substance-containing reservoir layer, an active substance-impermeable backing layer, and optionally a protective layer which is detachable from the skin contact layer, wherein the skin contact layer is in direct contact with the active substance-containing reservoir layer. The skin layer or the skin layer and the reservoir layer may be equipped with adhesive strength-increasing additives, for example silicone oils. Furthermore, the system may be equipped with an active substance-free over-patch in order to ensure a sufficient adhesion onto the skin over the application duration. In comparison to comparable systems with a release-determining membrane, a similar bioavailability of the active substance was achieved, such that these systems are bioequivalent to the membrane-containing systems.
