    摘要: A disturbance, for example, a frequency variation, is generated in at least a portion of the power distribution network. The disturbance may be generated, for example, by an uninterruptible power supply (UPS) or some other component of the power distribution network, such as a switch. At least one node of the network experiencing the disturbance is identified and a topology of the power distribution network is determined responsive to identifying the at least one node. The at least one node may be identified by detecting a voltage-related artifact corresponding to the disturbance. A phase-locked loop (PLL)—based circuit may be used for fast artifact detection. Groups of devices in the network may be identified from the artifacts, and combinatorial optimization techniques may be used to determine connectivity within such groups.

    摘要: A bra comprised of separate left and right breast support members where each breast support member comprises a section of flexible sheet material formed to define a concave cavity and having tabs projecting radially outwardly from the cavity rim. Each breast support member defines a rear facing surface encompassing the cavity and tabs, which carries a pressure sensitive adhesive for adhering to a user's skin. The concave cavity constitutes a cup for accommodating the user's breast while the tabs enable the user to readily manipulate the support member for optimally positioning the user's breast relative to the cut of a deep plunge garment.

    摘要: Computer systems and methods allow users to annotate content items found in a corpus such as the World Wide Web. Annotations, which can include any descriptive and/or evaluative metadata related to a document, are collected from a user and stored in association with that user. Users are able to annotate and view their annotations for any document they encounter while interacting with the corpus, including hits returned in a search of the corpus. Users are also able to search their annotations or to limit searches to documents they have annotated. Metadata from annotations can also be aggregated across users and aggregated metadata applied in generating search results.
