    • The invention relates to a miniaturized terahertz radiation source based on the Smith-Purcell effect. According to the invention, an energy-rich electron beam is emitted from a focused electron source at a defined distance across a metal grid of transversal grid rods so that oscillating image charges emit electromagnetic waves of a wavelength that can be adjusted on the basis of the periodicity of the webs and the electron speed. The elements of the radiation source such as the field emitter (1), the electrostatic lens (4), the beam deflector (5), the metal grid (7) and a second anode (8) are located on a semiconductor chip integrated by means of additive nanolithography methods. The field electron source is configured as a highly conductive wire with a stabilizing external resistor that is produced by additive nanolithography methods and protrudes from the surface. Said wire is produced by computer-controlled deposition lithography as a self-contained straight or arcuate structure. The base material, in its surface, has a track structure for the electrical connections and links (2) with controlled supply terminals (3) for supplying the field emitter tips (1), the lens (4) and the control electrodes (5, 8) with power. The terahertz radiation source according to the invention is powerful and can be used as a modular component irrespective of its spatial arrangement.

    • The present invention is essentially a method and system for leaving and retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location of the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combination of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate point within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

    • An apparatus and method for windlocking a curtain (100) over an opening in a building is disclosed and claimed. The windlocking curtain (100) resides to the exterior of the window, door or other opening and protects it from the intrusion of air, water or debris. In its upper position the windlocking curtain (100) permits normal use of the opening and in its lower position it secures the opening. A flexible corrugated curtain (115) has tension rods (123, 124) therethrough and the tension rods (123, 124) run in tracks (111, 112) on each side of the curtain (115) and necessarily on each side of the opening. Interengagement of the tension rods (123, 124) with tracks (111, 112) is accomplished by deformations in the rods that are referred to as interrupts (121). In one embodiment the tension rods (123, 124) are successively longer from top to bottom of the curtain (115) and their interrupts matingly wedge with angled tracks (111, 112) to secure the curtain (115). In another embodiment the interrupts (705, 707, 710) matingly engage parallel tracks (602, 603) upon the application of force due to wind, fluid (usually water or sea water) or debris. In another embodiment a flap on the edges of a flexible curtain (2200) engage the side tracks (2004) absorbing shocking and sealing the opening. A method for securing the opening utilizing the apparatus is also claimed which provides top, bottom and side securement.
