Abstract: The present invention features a dual-band meander line loaded antenna (MLA) that operates in a loop mode for a first frequency band and utilizes capacitive tuning to adjust the monopole resonant frequency for a second frequency band. In one embodiment orthogonal MLA elements are equipped with one or more capacitive flaps to lower the monopole resonant frequency of the structure. By offset-tuning the MLA elements and properly feeding RF signals, the inventive antenna exhibits vertically polarized operation at a first operating frequency and circular polarization at a second operating frequency. A typical use for the inventive antenna is for a dual-purpose cellular phone and GPS antenna. In cellular phone mode, the antenna operates at approximately 845 MHz with vertical polarization while simultaneously operating with circular polarization as at 1.5 GHz for GPS services.

Abstract: A thermodynamically stable, protective coating layer is applied by thermal spray technique to the inner and outer surfaces of a quartz crucible used for mono or polycrystalline silicon crystallization processing, inhibiting fusion between the silicon melt and the vitreous silica of the crucible, contamination of the silicon melt by contaminants released from the crucible by devitrification, and any chemical reaction occurring between the crucible and any supporting graphite structure. A powdered form of a suitable protective coating material compatible with high temperature plasma spray techniques, such as magnesium zirconate, barium zirconate, or stabilized zirconium oxide, is fed into a high temperature and high speed plasma jet directed at the crucible. The powder particles are softened or melted in the jet and deposited on the surfaces of the quartz crucible, and allowed to cool and harden into a protective coating.

Abstract: A collimator is provided to collimate light from a lambertian light source in which light from a fluorescent lamp is reflected towards an exit slit and in which light which leaves the slit at 180 degrees and is collimated in one direction to +/−1/2 degree. The collimator is utilized in one application to maximize the diffraction efficiency of a diffractive color separator microlens array to increase the brightness of a color liquid crystal display and to increase color saturation.

This light in one embodiment is spread out by a reflective array and is further collimated by a cylindrical lens array so that it exits a panel with the required +/−1/2 degree collimation.

Abstract: The present invention features a stacked, multi-band, antenna system consisting of a low-frequency, forward portion and a gridded, rear portion designed for operation at a higher frequency. Both front and rear radiating elements may share a common ground plane or the rear element may form a ground plane for the front element.

By properly choosing element sizes and spacings, and orienting the various antennas, a frequency band ratio of as little as 4:1 may be obtained.

Abstract: The invention is a distributed airways airflow dryer system for coffee beans and other such bulk crops. The interior volume or container of the dryer or dehydrator system that holds the bulk crops, is filled with an airways network structure that provides uniformly distributed open wall airflow passageways in the bulk crops. The airflow passages communicate with airflow openings in the walls or bottom of the container, to divide and admit the drying airflow into and through the full volume of the bulk crops as a large number of individual airstreams. Corrugated, ribbed, or cross-ribbed airflow plates are preferred embodiments that provide narrow open grooves or channels that expose the beans or kernels of the bulk crop directly to the airflow. This results in faster drying and greater uniformity of the drying effect on the full volume of the bulk crops.
