Abstract: Aspects concern a data storage system comprising a data storage for storing data comprising a plurality of data elements, wherein each data element is associated with a data storage table, a data storage access interface configured to receive a request for an access to a data element from a data access client wherein the request comprises a identifier of the storage location of the data element and an access controller configured to determine a data storage table with which the data element is associated from the identifier of the storage location, determine whether the data access client has access rights to the determined data storage table allowing the access to the data element and grant the data access client access to the data element if the data access client has access rights to the determined data storage table allowing the access to the data element.

Abstract: A small size, energy harvesting, long distance wireless AC sensor module. The sensor module includes an electromagnetic energy harvesting method that supplies and manages power to the sensor. Therefore, the sensor module does not rely on wired power or battery to run. The sensor also includes a low power wireless transmitter that has transmission frequency of sub-1 GHz and effective transfer distance of more than 100 meters, more than 150 meters, more than 200 meters and up to 250 meters. It has small size preferably having a size of less than 68 mm long by 33 mm wide by 21 mm thick, less than 50 grams. Thanks to the wireless and energy harvesting features, the sensor is very easy to install. Users just need to clamp sensors to the subject electrical lines, and then the data will be sent to data gateways automatically.

Abstract: The present invention relates to an optical network including a bridge for selectively transferring information from an optical channel carried on a first WDM optical waveguide to at least two optical channels on a second WDM optical waveguide. The first and second optical waveguides carry WDM optical signals each having plural optical channels. A bridge is interposed between the first and second optical waveguides which includes an optical add-drop multiplexer optically communicating with each waveguide. At least one optical channel having first and second data bits streams is dropped from the first waveguide. The first and second data bit streams are respectively encoded on two different optical channels which are then added to the second optical waveguide.

Abstract: The present invention provides a flexible WDM optical communication system in which each optical channel of the WDM optical communication signal can simultaneously accept multiple data formats. In one embodiment, the WDM optical system includes an optical waveguide having an optical add-drop multiplexer to selectively add and/or drop one or more optical channels to/from the WDM signal carried on the waveguide. A first source of data imparts information onto a first optical channel in a packet format while a second source of data imparts information onto the first optical channel in a time division multiplexed format. Other data sources having other data formats may also be included. An optical network interface electrically communicates with the data sources, placing the data from these sources onto the first optical channel which is generated from an optical source such as a laser. An optical path carries the optical channel from the optical source to the optical add-drop multiplexer.
