    摘要: An improved glass mount antenna system employs a pair of coupling plates having planar cavities disposed therein with any ground plane portion thereof. Surfaces of the coupling plates which are opposite that of the ground plane include a printed exciter strip which crosses the planar cavities to thereby provide an effective communications antenna assembly which is inexpensive to manufacture and especially well suited for high frequency communication operations such as the ultra-high frequency microwave bands of between 1.5 GHz and about 2.4 GHz which are currently intended for PCN/PCS communications.

    摘要: A wireless intelligent personal server includes a radio frequency (RF) receiver, a memory for storing electronic files, a set of embedded machine language instructions, a central processing unit (CPU), a first interface for a display device, such as a personal digital assistant (PDA), and a second interface for a wireless telephone. The RF receiver receives downstream data transmitted over a downstream wireless communications channel. The CPU executes the machine language instructions to process the downstream data and, thereby, either update an existing target electronic file stored in the memory, so that the target electronic file reflects changes made to a source electronic file, or create a new electronic file in the memory. A display device may be brought into communication with the wireless intelligent personal server, via the first interface, to access the electronic files stored in the memory. The wireless intelligent personal server may also transmit an upstream signal over an upstream wireless communication channel, such as by using a wireless telephone, in communication via the second interface. The upstream signal may acknowledge receipt of the downstream data, or it may include upstream data reflecting changes to the electronic files stored in the memory made by the display device.

    摘要: In situ formation of U(VI)-Fe(III) oxides and hydroxides can provide effective uranium remediation. The reason for this is that such compounds can effectively sequester uranium, even in the (VI) oxidation state. Such compounds can be formed in situ by 1) providing Fe(II), 2) reducing uranium to U(IV), and 3) oxidizing the resulting mixture to provide the desired U(VI)-Fe(III) oxides and hydroxides.

    摘要: A low cost glass mount vehicle antenna system utilizes, in a preferred embodiment, an over-coupled quasi-TEM mode transmission line coupler having two simple stamped or printed plates stacked over an L shape internal ground plane. The two conductive plates are located on opposite sides of the glass. With proper open circuit terminations on two of the four coupler ports, the backwards and forward coupling signals are redirected/combined and are effectively fed diagonally between the other two ports, thereby achieving through-glass coupling. The over-coupling achieves this efficient through-glass coupling effect at two spaced-apart frequencies (e.g. 800 MHz and 1800 MHz). The coupler is of a low impedance type and can be used with a variety of collinear array and elevated-feed antennas. It features high efficiency, low backwards radiation, and mechanical simplicity.

    摘要: An improved glass mount antenna system employs a pair of high dielectric constant, high Q, low loss dielectric resonators for TE011 and TE111 resonance mode coupling to couple RF energy through the glass to thereby provide an omni-directional communication antenna system characterized by high radiation efficiency and low pattern distortion. The antenna assemblies are especially well suited for high frequency communication operations, for example at microwave bands of between about 1.5 GHz to 2.4 GHz, currently contemplated for PCN/PCS communications.
