Abstract: A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.

Abstract: An apparatus is disclosed for releasably holding a toolholder shank having a lockable surface and a releasable surface utilizing an actuating bolt with an associated threaded actuating nut. When the actuating bolt is rotated in a locking direction, the actuating nut is drawn onto the bolt thereby clamping against the lockable surfaces of the toolholder shank. When the actuating bolt is rotated in the releasing direction, a releasing segment acts upon the toolholder thereby ejecting it from the tool support member.

Abstract: An apparatus and method for clamping an insert in a tool holder includes a recess and a clamp pin with a lever portion having a curved surface at each end thereof. The recess includes an angled wall for engaging one of the curved surfaces of the lever portion. A wedge portion is disposed within the recess and operatively coupled to a lock screw such that rotation of the lock screw causes movement of the wedge portion in a first direction. A biasing force is applied to the lever portion to cause the clamp pin to move in a second direction that is different than the first direction. The wedge portion includes one or more angled walls for engaging one of the curved surfaces of the lever portion. Movement of the wedge portion in the first direction causes the angled wall of the recess to act as a cam surface to cause the clamp pin to pivot about a pivot point, P, located along a central axis of the clamp pin.

Abstract: Methods and apparatuses for designing a plurality of integrated circuits (ICs) from a language representation of hardware. In one example of a method, a technology independent RTL (register transfer level) netlist is partitioned between representations of a plurality of ICs. In a typical example of the method, a hardware description language (HDL) code is written and compiled without regard to splitting the design among multiple ICs. After compilation, a partition of the technology independent RTL netlist, obtained from the compilation, is performed among the multiple ICs. After a partition, the technology independent RTL netlist is mapped to a particular target technology (e.g. a particular IC vendor's architecture for implementing logic circuitry), and place and route tools may be used to create the design in multiple ICs (e.g. field programmable gate arrays).

Abstract: A method for making a magnetic disk, without chemical mechanical polishing to remove asperities, includes the steps of placing an annular-shaped element in a vacuum chamber, exposing a surface of the element to a beam of gas clusters while it is in the vacuum chamber, and thereafter applying a magnetic coating. The annular-shaped element may be a substrate, or it may be a substrate with a base coating such as glassy carbon or amorphous carbon. The substrate may be made of glass, preferably high quality fusion glass. The surface of the annular element may be textured by forming a sequence of concentric annular valleys, with plateaus being left between the valleys, before the magnetic coating is applied. A semiconductor wafer may also be smoothed by a beam of gas clusters to prepare the wafer for photolithography.

Abstract: A fluid jet cutting method and apparatus for cutting an object from a sheet. In one embodiment, a fluid jet stream is directed against a glass sheet to cut an annular disk substrate for use in a data storage device. The sheet is supported by first, second and third support members. The support surfaces of the second and third support members are respectively positioned inside central openings in the first and second support members. A vacuum pulls the sheet against the support surface of at least the second support member. Preferably, plural central openings in the first support member accommodate plural second and third support members, whereby plural substrates are cut from the sheet. The sheet preferably includes plural layers removably adhered to one another, whereby plural substrates are simultaneously formed by a single fluid jet stream. A protective layer may cover at least one surface to the sheet.

Abstract: A face hobbing cutter including a cutter body having a top surface and a bottom surface and a side surface extending between the top surface and the bottom surface. A plurality of slots are formed within the cutter body extending from the top surface inward into the cutter body. The slots are adapted to receive cutting blades wherein each cutting blade is fixed in position in the respective slot by a wedge clamping assembly. The wedge clamping assembly includes a wedge block and a wedge screw for operatively securing the wedge block within the respective slot. The wedge block includes an outwardly facing locking surface for engaging a side of the cutting blade. The face hobbing cutter further includes an adjustable stop. The adjustable stop is in communication with the slot to support the cutting blade at the desired height from the top surface of the face hobbing cutter.

Abstract: A single compression engine determines a plurality of discrete cosine transform (DCT) coefficients based on a discrete cosine transform of a plurality of blocks of data. The single compression engine provides first and second DCT-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of the DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the DCT coefficients.

Abstract: A cutting insert has an insert body with at least one pair of cutting regions. Each cutting region is comprised of a cutting edge and the cutting edges in a pair are diametrically opposed to one another about a pair axis. Each cutting edge of a pair faces a single rotary direction along a pair circle, and for each pair of cutting regions the cutting edges have cutting profiles that are not identical to one another. In a toolholder assembly utilizing this arrangement, the cutting edges of a pair protrude beyond the perimeter of the toolholder.

Abstract: An abrasive fluid jet cutting composition, method and apparatus for cutting an object from a sheet. In one embodiment, a fluid jet stream is directed against a glass sheet to cut a disk substrate for use in a data storage device. An abrasive slurry is delivered to a fluid jet head from a slurry tank. The slurry is formed by mixing water, abrasive particles, a surfactant or surfactants, and an acid or base. The head also receives a pressurized fluid from a fluid pump. The abrasive slurry and the pressurized fluid are mixed in the head to form the fluid jet stream. Preferably, the abrasive particles are 8-64 microns and may include recycled scrap. The slurry may also contain polishing particles that are smaller than the abrasive particles to affect polishing. In addition to reducing surface tension, the surfactant may cause the abrasive particles to flocculate or disperse.
