Abstract: The present invention is directed at water-reducible curing agents for epoxy resins, obtainable by reacting at least one diprimary amine, at least one mono-primary amine and at least one polyepoxy compound, wherein the molar ratio of the primary amino groups to the epoxy groups in the reaction is in the range of about 1.7:1 to 1:1, the ratio of the primary amines in the diprimary amine to secondary amines optionally present in the diprimary amine is more than 1:1, and the molecular weight (Mw) of the diprimary amine is 500 Daltons or less. These water-reducible curing agents show excellent utility in combination with epoxy resins for self-levelling applications and provide excellent finished properties such as high compressive strength, low shrinkage, high impact resistance and high wear resistance in comparison to the commercially available products.

Abstract: Applicants have created systems, methods, and apparatuses for tracking the display of media-based content in real time. The inventions can include a first media device adapted to output media, a first display unit adapted to display the outputted media, and an apparatus adapted to receive metadata associated with the outputted media and compare the metadata with data. The apparatus can further be adapted to output the media and one or more of a warning indicator and a status indicator if at least a portion of the metadata and the data match as a result of the comparison of the metadata with the data. By tracking the display of media-based content, the inventions described herein can prevent an end user from accessing previously accessed media-based content, restrict the content a given end user is permitted to access, and ensure the licensing terms of a copyright owner's content are properly enforced.

Abstract: In accordance with embodiments of the invention, RFID network control devices (RNCDs) are provided wherein RFID traffic signals from any one of multiple RFID readers may be routed to any of the RFID antennas coupled to the RNCD. Each reader coupled directly or indirectly to the RNCD, either through its own action or the action of the external host controller managing the reader, may issue commands to the RNCD, over the same cable used to carry RFID traffic signals, and cause the RNCD to set its internal switch configuration such that a channel is established for RFID traffic signals between that reader and a particular RFID antenna coupled to the RNCD. This may include commands from the reader or external host controller which place other intervening RNCD units in a bypass state so as to establish the required communications channel with a minimum of signal strength loss.

The method may include electrochemically consuming an oxidant from a cathode coupled to the PBI membrane in response to a disconnection of an external load and supplying fuel to remove or electrochemically consume any back-diffused oxidant to the associated fuel cell sufficient to replace or consume the back-diffused oxidant while the external load is removed, and/or also may include controlling a standby temperature of the fuel cell. In this way, it may be possible to avoid increased cell voltage decay associated with degradation of the PBI in a simple and cost effective system.
