Abstract: A retaining-locking system for chain link fence slats includes specially notched fence slat elements having a pointed upper or lower end. The slat elements are sized and shaped to be interwoven between consecutive links of a chain link fence. A retaining-locking strip is formed of resilient material, and has an inner surface and an outer surface and at least one securing protrusion. The securing protrusion is sized and shaped to fit slidably within the notch. The protrusion is located on the outer surface of the strip. When the slat elements are interwoven into between consecutive links of a chain link fence with each of the notches aligned with one another, the retaining-locking strip inserted between the slat elements and the links, with the securing protrusion disposed within the slats, the strip will urge the slats toward the links, thereby retaining the slats within the chain link fence.

Abstract: A method, system and program product are described for generating a clock distribution network on an integrated circuit by determining an allowable placement region for each of a set of clock tree leaf elements in the integrated circuit. This allowable placement region is generated by determining and intersecting a set of sub-regions under different constraints, each of which identifies an area in which the clock tree leaf element is placed to satisfy the respective constraint. Constraints for which sub-regions are determined include timing constraints in the form of slacks and congestion constraints. After allowable placement regions have been determined, the clock tree leaf elements are clustered, and each clock tree leaf element is placed at a location within its allowable placement region which minimizes some cost function for that clustering.

The dividers have sufficient rigidity to resist bending and to provide guidance of products placed between adjacent dividers. The base member includes a plurality of divider positioning cavities operatively associated with a first end of the divider which allow placement of the dividers in a predetermined configuration to accommodate a desired size of products. The alignment member receives a second end of the divider and retains the dividers in the predetermined configuration.

Abstract: A computer is disclosed. The computer has a general register file of registers, a RISC instruction decoder, and a CISC instruction decoder. The RISC instruction decoder is exposed for execution of user-state programs in a RISC instruction set, being an instruction set having fixed-length instructions and a load/store/operate organization. The hardware CISC instruction decoder is exposed for execution by user-state programs in a CISC instruction set, being an instruction set with variable-length instructions and many instructions having multiple side-effects. The CISC decoder is designed to decode a portion of an instruction set for the computer, and to deliver the decoded instructions to an instruction execution pipeline designed to execute the output of both the RISC instruction decoder and the CISC instruction decoder. A software emulator is programmed to implement a remainder of the instruction set.

Abstract: A beverage dispensing apparatus being formed so as in use to provide a vortex motion in the mass of beverage flowing through the apparatus. In the vortexial flow, a low pressure area is produced at the center of the vortex so that the pressure in that region falls below equilibrium pressure and thus results in gas separating out from the liquid beverage. Since the gas breakout is achieved without the need for a flow restrictor, the pressure drop associated with these devices does not occur. Consequently, the beverage may enter the apparatus at a lower pressure. Moreover it has been found that a high quality head is formed on the draught beverage dispensed from the apparatus of the invention.

Abstract: A language-independent speaker-recognition system based on parallel cumulative differences in dynamic realization of phonetic features ( i.e. , pronunciation) between speakers rather than spectral differences in voice quality. The system exploits phonetic information from many phone recognizers to perform text independent speaker recognition. A digitized speech signal from a speaker is converted to a sequence of phones by each phone recognizer. Each phone sequence is then modified based on the energy in the signal. The modified phone sequences are tokenized to produce phone n-grams that are compared against a speaker and a background model for each phone recognizer to produce log-likelihood ratio scores. The log-likelihood ratio scores from each phone recognizer are fused to produce a final recognition score for each speaker model. The recognition score for each speaker model is then evaluated to determine which of the modeled speakers, if any, produced the digitized speech signal.
