Abstract: A microelectromechanical system (MEMS) device for sensing a magnetic field comprising: a base; a cantilever attached to the base structure at a first end and movable at a second end, the second end oscillating at a predetermined frequency upon application of a current; a magnetic sensor attached to the movable second end; at least one flux concentrator mounted on the base adapted to transfer magnetic flux to the sensor; whereby when the current is applied, the oscillation of the cantilever causes the sensor to oscillate between the lines of flux transferred from the at least one flux concentrator resulting in the shift of the frequency of the sensed magnetic field to the predetermined frequency. The invention further comprises a method of making the MEMS device.

Abstract: A magnetic storage medium and method of manufacturing the same comprises a substrate, a magnetic material adjacent to the substrate, and regions of variable magnetic permeability in the magnetic material, wherein the magnetic material may comprise a multilayered structure. Moreover, methods are described for making two kinds of media, read only and read/write media. Additionally, the magnetic material comprises any of permalloy, metallic glass, copper, nickel, iron, cobalt, boron, silicon and any combination thereof, and the magnetic material is approximately 10 to 1,000 nm thick. The regions of variable magnetic permeability comprise regions having a lower permeability than other regions, wherein the regions having a lower permeability than other regions is crystalline, and the regions having a higher permeability can be either crystalline or amorphous, and wherein the areas of lower and higher permeability are dimensioned and configured to be approximately 1 to 20 microns in size.

Abstract: A fiber spreader is provided which reduces fiber damage that occurs during preading. The fiber spreader includes a thin electrically grounded support sheet for supporting a layer of fibers on one surface thereof. The fibers supported on the support sheet are guided by a plurality of guide rollers past at least one corona discharge region at which the fibers are spread substantially uniformly. A motor driven spool advances the support sheet past the corona discharge region. The fibers are attached to the support sheet by an electrostatic attraction. The guide rollers are positioned so as to provide at least one region in which the sheet and the fibers are physically separated to allow for the uniform spreading of the fibers. After the fibers are spread, the fibers and the support sheet are united again and collected on a motor-driven spool.

Abstract: A camera device for including separate information area on a photograph is disclosed utilizing means for modifying a conventional instant camera having a lens and photographic film. The device is interposed between the lens and photographic film to produce a composite photograph having an information portion and an image portion. To that end, the device includes an information carrying slide which is in light transmissive communication with a first portion of the film. A lamp housed within an opaque enclosure to direct light through the slide towards a first portion of the film, concurrently with the taking of a picture. When a picture is taken, light images pass through the lens to reach a second portion of the film, concurrently with the lamp being lit to produce a composite photograph containing both the light images and the information on respective portions of a single photograph.
