Abstract: The present invention relates to methods for preparing an aqueous acrylamide solution having a low acrylic acid concentration. In addition, the present invention relates to methods for reducing the acrylic acid concentration of an aqueous acrylamide solution. The methods involve a bioconversion of acrylonitrile to acrylamide in the presence of a biocatalyst, wherein during the bioconversion the content of acrylonitrile is maintained at 0.3 w/w % or more referred to the total weight of the composition in the reactor. Also provided is an aqueous acrylamide solution which is obtained by the methods of the present invention. Furthermore, the present invention is related to an acrylamide homopolymer or copolymer obtained by polymerizing the acrylamide of the aqueous solution.

Abstract: A charging station for charging a battery which is arranged in an electric or hybrid vehicle, which charging station can be used in different parking space situations.

Abstract: A sensor for identifying a mechanical deformation of a housing of a charging column configured to charge an electrical energy store of an electrically driven vehicle. The sensor includes an elongated arm having a first end portion arranged in the longitudinal orientation and a second end portion opposite the first end portion in the longitudinal orientation. The arm is connected at its first end portion to a base of the charging column and runs in the longitudinal orientation approximately parallel to a part of the charging column that is sensitive to deformations of the housing, in particular to a side wall of the housing. An electrical probe element is arranged on the second end portion of the arm. An activation element is connected to the part of the charging column that is sensitive to deformations of the housing and is configured to activate the electrical probe element.

Abstract: Methods and systems for the remote certification testing of user video devices. In an embodiment, test logic and any related test input data is sent from a remote source such as an application server to a user video device. The test logic is executed at the user video device, and test results are output. The test results are sent back to the application server. The operation of the application server may be facilitated by a database. In embodiments, such a database stores test logic and test input data, and/or stores tests results for subsequent analysis.

Abstract: Methods and systems to provide supplemental content to a user who is viewing video or other content. The user's device (through which he will access the video) then provides an identifier of that video to a server or other computing facility. Here, the video identifier is used to identify supplemental content that corresponds to the user's video. The supplemental content is then provided to the user device for the user's consumption. The supplemental content may be structured in such a way that pieces of the supplemental content are accessible at particular points in the video. The piece(s) of the supplemental content available at a particular point in the video will be related to one or more objects that are present at this point. This allows a user to access one or more pieces of supplemental content in a context-specific manner, at a point in the video where the piece(s) of supplemental content are relevant.

Abstract: Methods and systems to indicate events of interest to a user. IN an embodiment, an event processor queries each of a plurality of event data sources, then receives event data from one or more event data source. The event processor then identifies an event to be indicated to a user device based on the event data. The identified event to the user through a user device. The event processor may receive, via the user device, feedback regarding the identified event. This feedback may be used to train future event identification. The event processor may be implemented at a computing device that is remote from the user, such as a server. Alternatively, the event processor may be implemented internal to the user device.

Abstract: Methods and systems to improve the efficiency of a content delivery system. A local distribution node is introduced to the network, between the content provider and the end user device (i.e., the leaf node). The local distribution node is responsible for servicing a localized subset of the leaf nodes that would otherwise be serviced by a conventional server of the content delivery system. Requests for content are received at the local distribution node from leaf nodes, and content is received at the local distribution node for transmission to the leaf node(s). Content may be cached at the local distribution node to allow faster service of subsequent requests for this content. Caching may also be used to make the channel surfing process more efficient. If demand is high, a leaf node may be promoted to serve as an additional local distribution node. Leaf nodes may also share content among themselves.
