Abstract: Embodiments of an appendage wallet having a variety of configurations to contain papers, currency, and small devices that are readably attachable and detachable from a region of a body appendage hidden beneath body clothing. Embodiments include vapor-blocking layers interposed between leather and other multi-layered constructions configured to restrict water vapor reaching wallet compartments storing currency, important documents, or water sensitive devices.

Abstract: An apparatus for a low skew, low standby power clock network for a synchronous digital system. The power clock network comprises a reference network, maintaining a reference clock signal, and four clock spines, each with its own respective clock signal. To reduce clock skew within the power clock network (i.e., to keep the clock signals of the clock spines synchronous with the reference clock signal), the present invention employs the use of active and passive delay elements to compensate for such skew. A phase relation extraction logic compares the phase of the clock signals from each respective clock spine to the reference clock signal of the reference network. If it is determined that the clock signals of the spines lag the reference clock signal, the phase relation extraction logic will use an active control driver to “speed-up” the clock signals of the clock spines.
