Certain disclosed antenna elements provide a reduction in the footprint of the antenna elements while maintaining the performance characteristics by providing a greater surface area on either a top, middle or bottom portion of a CLMD antenna. Other disclosed antenna element arrangements provide improved radiation efficiency by providing metallic reflectors on the sides of antenna elements. The isolation characteristics of certain disclosed antenna elements are improved through the use of coplanar wave guides. The bandwidth may be improved through the use of stubs resonators. The bandwidth of the antenna elements may be improved without reducing isolation or shielding by providing a variable gap between two portions of the antenna elements.

    Abstract: An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain by using Radio Frequency (RF), Intermediate Frequency (IF), or baseband processing.

    Abstract: An organic light emitting display has a plurality of pixels and an external power line. The external power line diverts into a number of internal power lines connected to the pixels, and the internal power lines are segmented into at least two discontinuous parts. Electric current thereby flows in a smaller amount through the internal power lines to reduce power dissipation.

    Abstract: A paper abutted ruler is provided which can easily be moved on the surface of a surface plate and can simply and accurately be positioned in place. The paper abutted ruler is constructed such that magnet bases rotatably supported at their one ends to a bottom portion of a ruler body and having magnets affixed to lower surfaces of the magnet bases are disposed in the ruler body at opposite-side positions spaced in the ruler longitudinal direction, and the magnet bases are rotated in a direction to tilt upward in interlock with depression of an attraction release button disposed nearly at the center of the ruler body. By depressing the attraction release button to rotate the magnet bases in the direction to tilt upward, the magnet bases are held in a state forming a predetermined angle relative to the surface of the surface plate.
