    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 vertebral model for illustrating the alignment and misalignment of the spine is disclosed. The model consists of first and second members movably mounted to each other, the first and second members each having a longitudinal axis. The model also has a third member interposed between the first and second members. The first and second members are movable relative to each other between a first position, wherein the first and second members are coaxially aligned, and a second position wherein the first and second members are not coaxially aligned. The model also has a locking mechanism for releasably locking the first and second members in their second position. The first and second members are configured to resemble two adjoining vertebrae, and the third member is configured to resemble an inter-vertebral disc between two adjoining vertebrae. The invention permits the model to illustrate how the vertebra can be placed into and out of alignment.

    摘要: A campfire skewer consisting of an elongate member having a first end, a second end, a first portion adjacent the first end, and a second portion adjacent the second end. The first portion has a first axis and the second portion is offset from the first axis. The first and has means for impaling food. A hand grip is rotatably mounted on the first portion of the elongate member. By holding the hand grip and manipulating the second portion of the elongate member the elongate member can be made to rotate in a rotisserie-like fashion.

    摘要: A cavity resonator is provided which includes a shielded enclosure enclosing a volume and a unitary conductor disposed within the volume, the unitary conductor having a first inductor portion and a transmission line portion. The transmission line portion is included in a transmission line having a reference conductor separated from the transmission line portion by a dielectric element. An active semiconductor device is coupled to the unitary conductor, and is operable to conduct a current to the unitary conductor at a resonant frequency of the unitary conductor.

    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 meditation 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.
