Abstract: A network security server constituted of: a device detection functionality, the device detection functionality arranged to detect devices on a network on an ongoing basis; a state extraction functionality arranged to read the state of each of the detected devices; an abstraction functionality arranged to translate each of the read states to a common abstract format; a state analysis functionality arranged to compare each of the translated read states with a predetermined database of states; and a session control functionality arranged to control communication of each of the detected devices responsive to the comparison with the predetermined database of states.

Abstract: Disclosed is a (solar) light electrical power generation unit including a concentrator plane of one or more photo-concentrator structures and a conversion surface including one or more photovoltaic (“PV”) active regions. The conversion surface is substantially parallel to the concentrator plane, and actuators may adjust a relative position between the concentrator plane and the conversion surface while maintaining the parallel relation between the concentrator plane and the conversion surface.

Abstract: There is presented a system and method for initiating communication between a computing device with a client application accessing data from a server and a representative workstation associated with the server. According to the present invention, an activity detector may monitor inputs to the computing device and a behavior filter may determine whether the detected activity qualifies for the establishment of communication between the computing device and the representative workstation. A communication module may initiate a communications application, mode or link between the computing device and the representative workstation upon receiving a signal or indicator from the behavior filter.
