摘要:
A digital video recorder is provided which provides digital storage of realtime ultrasonic image sequences, replacing the conventional VCR with a recorder which does not degrade digital ultrasound images by analog conversion and recording. The digital video recorder is operated by softkey controls in a displayed toolbar which are familiar to a VCR user. The virtual controls of the toolbar are selected by a video pointing device to stop, start, control replay speed, and skip to various points in a realtime ultrasonic image sequence which was stored by the digital video recorder.

A digital video recorder is provided which provides digital storage of realtime ultrasonic image sequences, replacing the conventional VCR with a recorder which does not degrade digital ultrasound images by analog conversion and recording. The digital video recorder includes a user control which enables a user to mark real time images as they are acquired or as they are being reviewed from storage. The user can skip directly from one marked image to another, or from one marked cardiac cycle to another.

A turf aerating device and machine including a turf aerating device comprising a base platform having a plurality of star-shaped spikes removably mounted therein in perpendicular orientation with respect to the base platform surface so that the spikes vertically penetrate a desired turf surface. The spikes produce X-shaped holes and loosen the soil beneath the turf. A plurality of turf aerating devices are mounted to a corresponding number of vertically actuating rods and vertically actuated for penetrating the turf with the spikes without causing damage to the turf.

A support mechanism for a rotatable wafer-support susceptor adapted for rotation by a shaft in a vertical orientation. The support mechanism comprises a quartz pedestal tube resting with frictional engagement on a metallic table fixed to the shaft. The pedestal supports, with frictional engagement, the base of the susceptor and is rotated by frictional engagement with the table. Means disposed within an aperture of the base and within the tube constrain the base, and thus the susceptor, and the tube to symmetrical rotation about the shaft passing through a centrally located aperture in the base.

An inner belt fits along the juncture of a person's stomach and thighs. The inner belt has first and second arches with a garment supported by the arch and the arch sized to offset the garment's waistline from the inner belt. Each arch has a front end a rear end fastened to the inner belt. The front end of each arch is located so it fastens to the inner belt adjacent the user's crotch during use. The rear end of each arch is located so it fastens to the inner belt at or before the hips of the user during use. A first loop extends from each arch, over the waistline and a normal, outer belt threads through the first loops and also through the normal belt loops on the garment. The outer belt supports the garment and the first loop and arches support the outer belt in a position offset from the inner belt. One or more second loops can optionally be fastened to the back of the inner belt to extend over the waistline and support the outer belt along the user's back. Localized stiffeners can be added to the first and second loops, inner belt and arches in order to keep the top of the loops above the waistline and reduce distortion of the waistline where the loops connect to the outer belt.
摘要:
A belt and garment fasten around a user's waist to support the garment at a selected waistline position. The belt has first and second arches with each arch having a front end a rear end fastened to the belt. The front end of each arch is located so it fastens to the belt adjacent the user's crotch during use. The rear end of each arch is located so it fastens to the belt at or before the hips of the user during use. Two first fasteners are connected to each of the arches adjacent a top of the arch. The garment has two second fasteners connected to a waistband of the garment. The second fasteners are located to releasably engage the first fasteners to fasten the arch to the garment so the arches hold the waistline of the garment above the belt. The garment covers the belt and arches. The garment is optionally connected to the belt by a third fastener located between the arches, along the user's back.

A carrier shell and a central divider are molded of a resin composition and are assembled to form a beverage bottle carrier. The carrier shell is molded in a flat sheet with living hinges between a bottom panel, opposite side panels and end panel sections that are operatively positionable by folding at the living hinges to form a generally rectangular box configuration with an open top. Male and female tabs on the carrier shell interface with the central divider and interlockingly engage to secure the carrier in the box configuration with the central divider extending parallel between the opposite sides. Secondary dividers extend between the opposite sides and the central divider to form individual bottle compartments for placement of beverage bottle therein. The bottom of the carrier may include recesses for receiving the tops of bottles stored in a like carrier directly below the upper positioned bottle carrier to thereby facilitate vertical stacking of the bottle carriers when filled with beverage bottles.
