A stacked microelectronic assembly includes a base substrate having conductive elements projecting from a bottom surface thereof and a first microelectronic subassembly underlying a bottom surface of the base substrate. The first microelectronic subassembly includes a first dielectric substrate, a first microelectronic element connected with the first dielectric substrate and first conductive posts projecting from the first dielectric substrate toward the bottom surface of the base substrate for electrically interconnecting the first microelectronic element and the base substrate. The assembly also has a second microelectronic subassembly overlying the base substrate. The second microelectronic subassembly includes a second dielectric substrate, a second microelectronic element connected with the second dielectric substrate and second conductive posts projecting toward the top surface of the base substrate for electrically interconnecting the second microelectronic element and the base substrate. The first microelectronic subassembly has a first height and the conductive elements projecting from the bottom surface of the base substrate have a second height that is greater than the first height of the first microelectronic subassembly.

A packaged chip is provided which includes a package element on which a signal-bearing conductive trace has an edge laterally adjacent to an edge of a reference conductive trace (e.g., ground trace) on the same face of a dielectric element, the two traces together functioning as a capacitor. In a particular embodiment, the laterally adjacent traces provide shunt capacitance to compensate for an inductance in a signal path to the chip which includes the signal-bearing conductive trace. In a variation thereof, a transmission line or waveguide is provided which includes the signal-bearing conductive trace and reference trace. In further variations, transmission lines are provided which include one or more metal layers of a package element, separated from each other by a thickness of a dielectric element included in the package element or the air gap between the package and a circuit panel.

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.

A microelectronic package is provided in which a first chip having active elements, e.g. amplifying elements, and passive elements, e.g. resistors, capacitors and inductors, is mounted in electrical communication with a microelectronic element having conductive patterns opposing a front face of the first chip. Absorptive material patterns are disposed between the conductive patterns of the microelectronic element and at least some of the passive elements while leaving at least some of the active elements exposed so as to attenuate radio frequency energy propagated by wave between the passive devices and conductive patterns of the microelectronic element. A packaged chip is also provided in which a chip is disposed beneath a package element, the chip having an opening which extends between a front face and a rear face of the chip, a conductor being disposed in the opening which is conductively connected to a conductive element of the package element.

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.

A split-E mechanism is provided for use on a flute having a right-hand steel, a left-hand steel, a first hinge rotatably mounted on the right-hand steel, a first key coupled to the first hinge, a second hinge rotatably mounted on the left-hand steel, and a second key. The split-E mechanism includes an actuator for actuating the second key in response to rotation of the second hand relative to the left-hand steel. The mechanism also includes a bridge device for interconnecting the first and second hinges for rotating the second hinge in response to actuation of the first key to operate the actuator.

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.

A stub-out assembly includes a stub-out conduit that defines a major diameter and a minor diameter. The minor diameter defines an attachment groove for receipt of a mount housing and a valve housing. The mount housing includes a multitude of circumferential fingers which each include a barbed end that engage a corresponding internal groove within the valve housing of the valve assembly. The mount housing fits over the minor diameter and a retainer in the mount housing is aligned with the attachment groove. The retainer includes a partially annular set of conduit attachment legs and a set of housing attachment legs. The conduit attachment legs engage the attachment groove to axially retain the conduit therein. The housing attachment legs each include a barbed end which engage a corresponding surface located within the slot.

Method and system for preparing a personal genetic profile includes collecting genetic data from an individual, assigning the data to a coordinate system, storing the data, and providing access for retrieval by the individual from whom the genetic data were collected, after receipt of an Identifier that adequately authenticates the identity of the data requestor. Locations of genetic markers are provided as three-dimensional coordinates, described with matrix relationships that are consistent with the primary and secondary chemical structure of molecular constituents of a DNA chain for the individual.
