Abstract: A storage container including an outer case having a bottom tray and a cover hinged to it and a tongue assembly in the bottom tray. The tongue assembly can be integrally formed, with the bottom tray and/or the cover or separately formed and subsequently inserted into the bottom tray. When separately formed it can include an outer frame and a tongue extending from the frame side to which it is pivotally attached to the frame center. The tongue has a compact disc retainer mounted thereon for fitting into a center opening of a compact disc and holding the compact disc in the frame center when the tongue is in a "down" position. When the tongue is in an "up" position, pivoted relative to the one frame side, the compact disc is lifted up away from the frame and bottom tray for easy access thereto. The tongue, the frame and the hinge therebetween are preferably integrally formed together and as one unit. According to one embodiment the tongue is formed with a natural upward or raised bias, an elastic memory.

Abstract: An automatic logic-model generation system operates on a behavioral description of an electronic design (e.g., a circuit, a system, etc.) to automatically generate a low-level (i.e., circuit-level) design of the electronic design, to lay out the electronic design for production in the form of an integrated circuit, and to produce logic-level models incorporating accurate timing (and delay) information. A verification process is also performed whereby the logic-level model is automatically verified for accuracy.

Abstract: A methodology for generating structural descriptions of complex digital devices from high-level descriptions and specifications using a systematic technique to map and enforce consistency of the semantics imbedded in the intent of the original, high-level descriptions. The design activity is essentially a series of transformations operating upon various levels of design representations. At each level, the intended meaning (semantics) and formal software manipulations are captured to derive a more detailed level describing hardware meeting the design goals. Important features of the methodology are: capturing the users concepts, intent, specification, descriptions, constraints and trade-offs; architectural partitioning; what-if analysis at a high level; sizing estimation; timing estimation; architectural trade-off; conceptual design with implementation estimation; and timing closure.

Abstract: A microelectronic circuit includes a plurality of circuitry blocks and sub-blocks, a clock driver, an electrical interconnect that directly connects the clock driver to the sub-blocks, and balanced clock-tree distribution systems provided between the electrical interconnect and circuitry in the sub-blocks respectively. A method of producing a hierarchial clock distribution system for the circuit includes determining clock skews between the clock driver and the sub-blocks respectively. Delay buffers are selected from a predetermined set of delay buffers having the same physical size and different delays, with the delay buffers being selected to provide equal clock skews between the clock driver and the distribution systems respectively. Each delay buffer includes a delay line, and a number of loading elements that are connected to the delay line, with the number of loading elements being selected to provide the required clock delay for the respective sub-block.

Abstract: A machine tool is provided in which a carriage is supported on the upper flat surface of a work table by first bearings. The carriage extends beyond the bearings in one direction to support a tool, so that the weight of the carriage and tool creates a moment tending to rotate the carriage downwardly toward the work table on one side of the bearings. This is countered by a second bearing that extends to a second downwardly facing surface which may be a separate element or the undersurface of the work table. The second surface is adjustable for parallelism with the work table. Linear actuators move the carriage over the work table. In a multispindle machine, three actuators are required, at least two of which are nonparallel.

Abstract: A removable heatsink assembly comprised of a heatsink unit and a heatspreader is provided. The heatsink unit has at least one fin and a coupling collar for radiating heat away from a packaged electronic device. The heatspreader includes a platform attached to an inner collar in thermal contact with the packaged electronic device. The platform has one or more tabs suitable for mating with one or more flanges located on the coupling collar of the heatsink unit. Coupling grooves within the flanges engage the platform of the heatspreader when the flanges are mated with the heatspreader tabs and the heatsink is turned. The heatsink can therefore be quickly and conveniently attached to or removed from the heatspreader. The present invention thus permits a wide variety of different heatsinks to be interchangeably used with a single heatspreader attached to an electronic device package.

Abstract: A still video image transceiver for use across narrow-band analog voice communication channels allows still video images captured or provided by a wide variety of consumer and industrial image sources, even those of the common hetrodyne-signal type, to be transmitted over a voice communication channel, such as over a telephone line or by high frequency radio communication. The captured video image is converted to an audio band signal using a digital linear signal processing method which avoids the common problem of first having to separate the image signal of its RGB color signal components. Use of a time-base corrector is avoided, while a jitter-free image for the receiver of the image is obtained even for those images which originate with asynchronous hetrodyne-type image source. Even over analog voice communication channels of marginal operating condition, an excellent signal to noise ratio is achieved because a limiter circuit is not used prior to demodulation of the received image signal.

Abstract: A polysilicon interconnect is formed on a microelectronic circuit substrate for conducting signals from a driver to a non-polycrystalline silicon contact which has higher impedance than the interconnect. A plurality of electronic "speed bumps" are spaced along the interconnect for disturbing or disrupting signals propagating along the interconnect toward the contact and thereby reducing undesirable back reflection and ringing. The speed bumps can include capacitance altering elements in the form of dielectric strips, or resistance altering elements in the form of low resistance doped areas or high resistance amorphous areas. The speed bumps can include first and second elements having different values of capacitance or resistance which are spaced along the interconnect in alternating relation.

Abstract: A method of cell placement for an integrated circuit chip includes performing a contraction operation by which at least some of the cells are relocated to new positions that provide lower interconnect wirelength. For each cell, the centroid of the net of cells to which the cell is connected is computed. The cell is then moved toward the centroid by a distance that is equal to the distance from the current position of the cell to the centroid multiplied by a "chaos" factor. This process continues until a specific energy condition is met; then the `expansion` mode is entered. An expansion operation is then performed by which the net force exerted on each cell by other cells in the placement and a resulting altered velocity of the cell are calculated, and a new cell position is calculated based on the altered velocity over an incremental length of time. The system stays in expansion mode until another energy criterion is met.
