摘要： An apparatus for piercing earlobes which comprises a pair of elongated, hand-held, parallel bars that can be moved towards and away from each other while an earlobe is positioned between the bars adjacent an end thereof. At that same end, one of the bars mounts an axially movable plunger to which an earlobe piercing stud can be attached. A compression spring drives the plunger and therewith the stud towards the second bar for piercing the ear. First and second levers are positioned for actuation by the same hand holding the piercing apparatus for retracting or cocking the plunger and for releasing it to pierce the earlobe. The second bar includes a recess into which a clip can be inserted which has an aperture for frictionally engaging the stud and retaining the stud to the earlobe after the latter has been pierced. The recess aligns the aperture with the axis of the plunger and a flat leaf spring is mounted to the second bar to bias the clip into the recess and retain it therein in its properly aligned position. The extent to which the two bars can be moved towards each other is adjustable.

摘要： The invention relates to a system and method of dispersion measurement in an optical fiber network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.

摘要： Planarization methods for maintaining planar surfaces in the fabrication of such devices as BAW devices and capacitors on a planar or planarized substrate are described. In accordance with the method, a metal layer is deposited and patterned, and an oxide layer is deposited using a high density plasma chemical vapor deposition (HDP CVD) process to a thickness equal to the thickness of the metal layer. The HDP CVD process provides an oxide layer on the patterned metal tapering upward from the edge of the patterned metal layer. Then, after masking and etching the oxide layer from the patterned metal layer, the patterned metal layer and surrounding oxide layer form a substantially planar layer, interrupted by small remaining oxide protrusions at the edges of the patterned layer. These small remaining oxide protrusions may be too small to significantly disturb the flatness of a further oxide or other layer or they may be further mitigated by the application of another HDP CVD oxide film.
