Abstract:
A write pole tip for a magnetic head has a trailing edge that is closer than a leading edge to a perpendicular recording medium, so that the write signal strength of the trailing edge is greater than that of the leading edge. Such an angled pole tip can write a sharp magnetic pattern with the trailing edge, reducing erroneous writing. A layer of physically hard material such as diamond-like carbon (DLC) may adjoin the trailing edge, the physically hard material layer protruding slightly after polishing of the media-facing surface due to its resistance to lapping. This can form an acute corner of the write pole tip adjacent to the physically hard material layer. The trailing edge may be longer than the leading edge, and the write pole tip may have a trapezoidal shape.
Abstract:
An artificial candle has a delicate glowing shroud or sock that can flutter like a candle flame, and the sock may surround a “wick” that can be seen through the sock to glow. Such a diaphanous sock can be actuated by a fan, air pump, solenoid or conductor, which can be provided adjacent to the sock or removed from the sock, for example in a central body of a chandelier. Light can emanate from the wick from a light emitting diode (LED), and the sock can include fluorescent material that absorbs and reradiates some of the light from the wick. The wick and the sock can be coupled to a shaft that simulates a wax candle body. A standard threaded fitting can be provided so that the artificial candle can thread into a socket to replace a light bulb.
Abstract:
A tool for assisting a medical professional in inserting an endotracheal tube in the trachea of a patient comprises a relatively rigid rod in the shape of an offset spiral. The tool has a mandrel section, a curved arc section smoothly transitioning from the mandrel section, and a tip section smoothly transitioning from the arc section. The arc section is an arc of a three dimensional spiral, and angularly and spatially offsets the tip section with respect to the mandrel section.
Abstract:
A hard disk drive has a head with a read element adjacent to a write element, with the write element extending closer to the disk than the read element so that the write element is close to the disk for writing sharp patterns and the read element is removed from the disk to avoid wear and thermal asperities. The write element is encompassed with diamond-like carbon (DLC) to allow at least occasional dynamic contact with the disk while the read element, which includes a magneto resistive material, is disposed in a recessed area and may be covered with a thin coating of DLC to avert corrosion. The disk may have a multilayer granular media for low-noise, high-strength perpendicular data storage. Perpendicular data storage may also be provided by keeping the write element in such close proximity to the media that perpendicular write fields predominate, while perpendicular signals from the media are favored by the read element.
Abstract:
Illumination devices are disclose having at least three thermally conductive fins that are attached to each other adjacent a central location and extend outward from the central location, with each of the fins having an opposed pair of major surfaces. The devices include a plurality of light-emitting diodes that emit light and produce heat, with at least one of the light-emitting diodes being mounted on each of the fins. The heat from the light-emitting diode flows along the fin and is radiated from at least one of the major surfaces, while the light from the light-emitting diode is reflected from the major surfaces of adjacent fins and exits the device.

An artificial candle has a delicate glowing shroud or sock that can flutter like a candle flame, and the shroud may surround a “wick” that can be seen through the shroud to glow. Such a diaphanous shroud can be actuated by a fan, air pump, solenoid or conductor, which can be provided adjacent to the shroud or distanced from the shroud, for example in a central body of a chandelier. The wick may be lighted by a light emitting diode (LED), and the shroud can include fluorescent material that absorbs and reradiates some of the light from the wick. The wick and the shroud can be coupled to a shaft that simulates a wax candle body. A standard threaded fitting can be provided so that the artificial candle can thread into a socket to replace a light bulb.

Abstract:
Methods for making devices comprise forming a plurality of transducers on a major surface of a wafer, including forming a plurality of solid layers each having a thickness that is less than one micron; dividing the wafer and the attached transducers into a plurality of units such that each of the units includes a portion of the layers and a substantially planar surface that is substantially perpendicular to the portion of the layers; and removing at least part of the substantially planar surface, including creating, for each transducer, at least one flexible element that is attached the transducer. Conventional problems of connecting a head to the flexure and/or gimbal are eliminated. The heads can be made thinner than is conventional and gimbals and flexures can be more closely aligned with forces arising from interaction with the media surface and from seeking various tracks, reducing torque and dynamic instabilities.
Abstract:
A suction catheter system including a durable transparent pouch used to hold irrigating solution and a catheter in a contaminant-free environment between uses. The suction catheter system allows the practitioner to reuse the catheter several times for the same patient rather than using a new catheter for each suctioning when the practitioner needs use of both hands and has to lay the catheter down.
