A support member such as a belt or sleeve includes a topographical pattern on its sheet contact side. A plurality of land areas, corresponding depressions, through voids, and / or groove areas are formed on the top surface of the support member to produce the topographical pattern. The land areas, corresponding depressions, through voids, and / or groove areas may be formed by graving, cutting, etching, embossing, mechanical perforation or a combination thereof. The improved belt or sleeve imparts desired physical characteristics, such as bulk, appearance, texture, absorbency, strength, and hand to a nonwoven product produced thereon.

An industrial fabric such as an endless belt or sleeve for use in the production of nonwovens, and a method of making thereof are disclosed. The industrial fabric is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, and joining the adjoining sides of the strips of material using ultrasonic welding or laser welding techniques. The fabric may then be perforated using a suitable technique to make it permeable to air and / or water.

Method and apparatus for a fast (low F / number) computational camera that incorporates two arrays of lenses. The arrays include a lenslet array in front of a photosensor and an objective lens array of two or more lenses. Each lens in the objective lens array captures light from a subject. Each lenslet in the lenslet array captures light from each objective lens and separates the captured light to project microimages corresponding to the objective lenses on a region of the photosensor under the lenslet. Thus, a plurality of microimages are projected onto and captured by the photosensor. The captured microimages may be processed in accordance with the geometry of the objective lenses to align the microimages to generate a final image. One or more other algorithms may be applied to the image data in accordance with radiance information captured by the camera, such as automatic refocusing of an out-of-focus image.

Novel solutions for position measurement, including without limitation tools and techniques that can be used for land surveying and in similar applications. One such tool is a greatly enhanced position measurement system that takes the form of a surveying rod with substantial independent functionality, which can be used with or without a total station or similar device.

An improved microelectronic spring structure, and method of making the same, are disclosed. The improvement comprises, in a spring contact of the type comprising a beam attached to a post, of replacing the post with a plurality of column elements. The beam component is thus provided with one or more column elements which both structurally support and electrically connect one end of the beam to an electronic component. The column elements are preferably comprised of relatively straight segments of wire elements that are ball-bonded to a substrate and are over-coated with suitable structural and / or conducting materials. In the alternative, the improvement comprises a single column element comprised of a relatively straight segment of wire that is ball-bonded to a substrate and over-coated with suitable structural and conducting materials, wherein the column element is essentially rigid. The improved spring structures are especially useful for use as spring contacts on substrates such as probe cards, interposers, semiconductor devices, and other electronic components.

A sheet metal hole cutter has a cap plate defining a substantially circular peripheral groove and an annular shelf extending radially outwardly from the peripheral groove. An elongated band forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge received within the circular peripheral groove in an abutting relationship with an inner edge of the groove. The band defines an axial depth of about ½ of an inch or less, and an outer diameter within the range of about 9 / 16 of an inch through about 6 inches. A weld region fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth of at least approximately 1 / 16 of an inch in order to prevent over-feeding of the hole cutter through a work piece. A plurality of teeth are disposed along a cutting edge of the band, and each tooth defines a cutting surface extending between an outer edge and an inner edge of the tooth. Each cutting surface is oriented at an acute angle relative to the plane of the cap plate such that the outer edge of the respective tooth is spaced further away from the cap plate than the inner edge to thereby preferentially cut the work piece with the outer edge and create a substantially burr-free hole in the work piece.

An electromagnetic band gap structure is provided including a ground plane and a periodic planar arrangement of surface elements mounted parallel to and at a predetermined distance from the ground plane. Each of the surface elements is supported in the planar arrangement by at least one conducting support element extending from an edge of the surface element to the ground plane, avoiding back-to-back parallel support elements. This arrangement allows for the surface elements and their respective support elements to be folded from flat metal templates to greatly simplify manufacture. An antenna is also provided in which an antenna element is mounted in such a way as to use the electromagnetic band-gap structure as a ground plane. This allows for a low-profile antenna to be made as the antenna element may be mounted close to the plane of surface elements in the structure.

Systems and methods that may be implemented to determine the location of an emitter of electromagnetic radiation having an unknown location, using a cooperative TDOA-based location methodology. The cooperative TDOA-based location methodology (e.g., such as TDOA / TDOA, TDOA / FDOA, etc.) may be implemented using at least one cooperative transmitter that transmits a cooperative electromagnetic (EM) signal from a known location that is received at multiple different EM sensing platforms that are also each of known location. The known geolocation of the cooperative transmitter may be used to resolve the signal arrival timing relationships between the different sensing platforms that is utilized to determine the location of another EM transmitter of unknown location.
