    摘要： An improved circuit for controlling the output power level of a radio frequency (RF) amplifier is disclosed. The circuit samples the output of an RF amplifier. The sample is amplitude modulated at a preselected modulation frequency and is passed to a detector. In repsonse to the amplitude modulated signal, the detector produces a signal whose amplitude is indicative of the RF amplifier's output power and whose frequency is the modulation frequency. The amplitude of the signal produced by the detector is then compared to a reference amplitude and the difference (error signal) is used to control the gain of the RF amplifier.

    摘要： Mediation sitting cushions and mats allow the user to meditate in comfort for great lengths of time, avoiding stress and pain often caused by traditional meditation cushions and mats. The layered mediation sitting cushions and mats combine a slow recovery visco-elastic foam (“VEF”), having load deformation properties and densities, with one or more base layers of a batting support. The sitting cushions and mats enable a person seated in traditional meditative positions to achieve a comfortable posture, regardless of the meditator's size or weight. The sitting cushions and mats also allow people to meditate in traditional cross-legged or kneeling postures comfortably, without irritation or pain. The mediation sitting cushions and mats also maintain of the pelvis in a neutral or slightly anterior position, resulting in proper alignment of the pelvis and spine, which minimizes the muscular and ligamentous strain caused by sitting in stillness for long periods of time.

    摘要： A transmission structure having high propagation velocity and a low effective dielectric loss. The structure comprises a dielectric, a first reference conductor disposed below the dielectric, a signal conductor disposed above the dielectric, and a second reference conductor disposed over the signal conductor. The second reference conductor has a recess portion facing the signal conductor, the recess portion defining a gap between the second reference conductor and the signal conductor. The gap may be filled with air which has a relative dielectric constant approximately equal to one (1). Because of the physical and dielectric constant characteristics of the gap, the structure concentrates an electric field in the gap resulting in an effective dielectric constant approximately (approaching) one (1) and an effective dielectric loss approximately equal to zero (0). Thus, the structure exhibits a propagation velocity approximately equal to the speed of light.

    摘要： A vertically elongated, hollow and lightweight housing including top and bottom walls and a plurality of interconnected sidewall portions extending between and connecting the top and bottom walls is provided. At least one of the sidewall portions has indicia thereon indicating a winning bingo game situation and the bottom wall includes a central opening formed therein about which a depending tubular neck integral with the bottom wall is disposed. An elongated wand is also provided including upper and lower ends and a mid-length portion extending between and connecting the upper and lower ends. The wand is slidingly telescopingly received through the neck and the upper and lower ends are slightly diametrically enlarged in relation to the mid-length portion of the wand. The upper and lower ends are tightly slidingly receivable through the neck and the mid-length portion of the wand is freely slidable through the neck. The lower end of the wand includes a diametrical enlargement thereon of greater transverse dimension than the outside diameter of the neck and the length of the wand is such that the upper end face thereof abuts against the inner surface of the top wall of the housing when the enlargement is in close juxtaposition with the lower end of the neck.
