Abstract: A real-time communication architecture establishes a continuous connection between an enterprise network and a communication management system. The connection is continuously held open allowing mobile devices real-time access to enterprise email systems. The real-time communication architecture can support an entire enterprise email system or individual email users. The foregoing and other objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment of the invention which proceeds with reference to the accompanying drawings.

Abstract: Improvements to the design of metal frames of security screens are disclosed. The improvement, each of which may be applied individually or in conjunction with any combination or all of the other improvements, include a retainer groove in the frame into which is inserted the ends of the screen mesh and of a tension retainer bar to prevent the mesh and bar from pulling away from the screen frame when a force is applied against the screen mesh, a second line of tension retainer bar fasteners, grooves on the retainer wall of the tension retainer bar to prevent fasteners from slipping during insertion, vinyl or felt extender tongues extending from the frame perpendicularly to each other, refinements to the design of the screen frame to maintain the structural integrity of the screen frame while accommodating the aforesaid retainer groove, and the insertion of the ends of a center brace into slots in the outside frame members or the use of insertion keys to better secure the center brace.

Abstract: A method for converting radiative energy, such as coherent laser radiation or non-coherent solar radiation, to electrical energy using a magnetohydrodynamic (MHD) electrode system comprises the steps of: (1) forming a magnetic pinching field for and directing moving charged particles through the MHD electrode system; (2) supplying an ionizable working substance within the magnetic pinching field; and (3) applying radiative energy to the working substance in order to produce moving charged particles therefrom, whereby the moving charged particles are and directed through the MHD electrode system for generating electrical energy. Residual radiative energy and recombined working substance are recycled in a fully enclosed system. In one preferred embodiment, the magnetic pinching field is formed along the major axis of an ellipsoidal reflecting surface, and the radiative energy is focused at the foci of the ellipsoidal surface with the consequence that the reflected energy is repeatedly focused at the foci.
