Appl. No.:

10/897276

International Classification:

G11B 9/00

US Classification:

369126000

Abstract:

A method for writing data to an optical medium includes directing intermittent pulses of a beam of electrons from an electron source onto an optical medium in a controlled pattern for creating surface features on the optical medium, the surface features representing data. A system for performing this method, according to one embodiment, includes a medium receiving portion for holding an optical medium, an electron source for emitting a beam of electrons at the optical medium on the medium receiving portion, and a steering mechanism for directing the electron beam onto the optical medium in a controlled manner. The beam of electrons strikes the optical medium in intermittent pulses for creating surface features on the optical medium, the surface features representing data.

Abstract:

A catheter shield comprising a dome surrounded by a peripheral, skin engaging flange. The dome defines a cavity, has a hole for the catheter, and has a radial slit extending to the edge of the shield to aid in placement of the shield around the catheter. Vents may be provided in the shield. The shield is held in place by holding the shield against the skin, moderately tensioning the catheter, providing means for preventing relative longitudinal motion between the catheter and the shield, and then releasing the catheter so the elasticity of the catheter and of the body parts which anchor it pull and hold the shield in place against the skin. A second method for securing the shield entails positioning the shield around the catheter, pressing the shield firmly downward against the skin, and applying a tape strip with one of its edges firmly against the top of the shield. When the hand pressure on the shield is released, the compressed portion of the body beneath the shield tries to expand and force the shield outwardly. However, since the tape strip prevents relative longitudinal motion between the shield and the catheter, the shield cannot move outwardly relative to the catheter and is thus held in place against the skin by the catheter and tape strip.
