A scheme for noise floor de-embedding by identifying a link or relationship between noise floor from an oscilloscope and phase jitter impact on a toggling signal. The scheme uses phase or electrical spectrum and phase detection for noise floor recognition. The scheme de-embeds the impact from random noise and also removes deterministic noise or jitter from the oscilloscope. The scheme provides accurate jitter analysis for a circuit (e.g., clock data recovery circuit) after de-embedding noise floor for the oscilloscope.

Method of blind anchoring for mounting on plasterboard or other dry wall panels having inaccessable backs, fixtures attachable by screws or bolts, the assembly having as a blind anchor member a strong stiff elongated machinable plate, as a puller a flexible string or cord passed through a central drilling in and knotted beyond the back of the plate, and a self-sticking adhesive coating on the front of the plate. Using a flange of the fixture as a marking template, an opening, within the perimeters of the flange and any screw holes therein, is cut through the wall. Sized to fit, the anchor plate with the string attached is inserted through the wall opening and after positioning manually by fingers extended through the opening, is pulled by the string against the inside of the wall. With the plate then held in position by the adhesive and the tensile force on the string, holes are drilled in the marked positions through the anchor plate for receiving the attaching screws. If the fixture is double-ended, the procedure is repeated at its other end before screwing both its ends through the wall to the then hidden anchor plates.

For use with a motor vehicle dashboard or other similar wall type configuration an automatic snuffer and disposal device including a pivotally mounted ashtray enclosure having a generally open upper area defined by two side walls, a rear wall and a front wall, the enclosure pivotally mounted by hinge means along the lower edge thereof for movement to a closed or open position, a stationary pressure plate fixedly mounted to the walls of the enclosure and a moveable pressure plate moveably mounted to the walls of the enclosure, the moveable pressure plate positioned adjacent the stationary crusher plate to form an upwardly facing configuration for receiving cigarettes, cigars and other tobacco materials therein for crushing therebetween, a cam means engageable with the moveable crusher plate when the ashtray enclosure is moved to a closed position to crush tobacco materials between the plates, also including a disposal means operable responsive to movement of the closure toward the open position for urging the moveable and stationary crusher plates apart to allow release of the crushed tobacco material for disposal.
