Abstract: A device for repairing a bone disorder using a polyaxial screw. The device has a pivoted lever mounted rotatably to an extension of a bone screw and which extends essentially at right angles to the longitudinal direction of the extension to which it is mounted and is in contact with a stop on the other extension associated with the vertebral body to be repositioned. The extension that acts on the polyaxial bone screw comprises a longitudinal sleeve, a rod, preferably threaded, extending from within the sleeve and moveable within the sleeve, and a contact surface disposed on the end of the threaded rod which is configured to transmit a force against the bone screw to prevent polyaxial movement of the polyaxial bone screw for as long as the force is transmitted.

Abstract: Methods and systems for configuration data management are disclosed. In one embodiment, a configuration management system may be configured to store a product operational control file for controlling a product based on configuration data. The configuration management system may define a plurality of orderable items and relationships between the orderable items and the configuration data. The configuration management system may receive an order for the product including a configuration requirement. The configuration requirement may include one or more of the orderable items. The configuration management system may then load the product operational control file and the configuration data onto the ordered product according to the defined relationship between the orderable item and the configuration data, and the configuration requirement of the ordered product.

Abstract: The present invention relates to methods and systems for identifying proteins. In particular the invention provides a method for identifying a protein through amino acid sequences of one or more query peptides generated from the protein. The method involves translating amino acid sequences of the query peptides to all possible codons from which the peptides can be synthesized to prepare strings of codons. Known nucleic acid sequences, in particular a set of known nucleic acid sequences including a genome, are searched to locate one or more known nucleic acids that comprise regions that match the strings of codons. Matching nucleic acids are ranked to identify nucleic acids that are true coding regions for the protein to thereby identify the protein.

Abstract: A suspension for a steering axle includes two links extending from the axle laterally inwardly to be attached to a lateral shackle plate. The lateral shackle plate is pivotally attached to the vehicle frame. The links may be two separate members, or may be a single V-shaped member. The links operate to transfer lateral loads between the two sides of a vehicle receiving the suspension.

Abstract: An “architecture generation engine” is operative with a CAD system to implement circuits into PLD (programmable logic device) architectures and to evaluate performances of different architectures. The architecture generation engine converts a high level, easily specified description of a PLD architecture into a highly detailed, complete PLD architecture database that can be used by a CAD toolset to map a circuit netlist into a PLD. The architecture generation engine also enables performance evaluation of a wide variety of PLD architectures for given benchmark circuits.

Abstract: An air suspension system for a non-drive steering axle includes a set of air springs supported on an axle beam extending between a pair of rotating wheels. The axle beam defines a lateral axis about which the wheels rotate. A lateral stiffener assembly cooperates with the axle beam, which provides torsional stiffness, to provide high lateral stiffness in the air suspension system. The lateral stiffener assembly includes a first arm that extends from the axle beam transverse to the lateral axis and is positioned on one lateral side of the vehicle. A second arm extends from the axle beam transverse to the lateral axis and is positioned on an opposite lateral side of the vehicle. Each of the first and second arms has one arm end supported by the axle beam and an opposite arm end mounted to a vehicle frame member.

Abstract: An interconnection architecture for programmable logic devices (PLDs) is presented in which heterogeneous interconnect resources can be programmably connected to function blocks in accordance with two or more operational parameters, such as, for example, signal propagation speed, circuit area, signal routing flexibility, and PLD reliability. Programmable interconnect resources include unbalanced multiplexers, different types of interface buffers, and signal wires of different widths and different wire-to-wire spacings.

The Architecture Generation Engine converts a high-level, easily specified description of a PLD architecture into the highly detailed, complete PLD architecture database required by the internals of the CAD toolset in order to map a circuit netlist into the PLD. The Architecture Generation Engine also enables the performance evaluation of a wide variety of PLD architectures for given benchmark circuits.

Abstract: Multi-FPGA systems (MFSs) are used as custom computing machines, logic emulators and rapid prototyping vehicles. A key aspect of these systems is their programmable routing architecture, which is the manner in which wires, FPGAs and Field-Programmable Interconnect Devices (FPIDs) are connected. The architecture disclosed uses a mixture of hardwired and programmable connections for interconnecting the FPGAs. A hardwired connection is a direct connection between a pair of FPGA I/O pins. A programmable connection refers to the scheme in which pair of FPGA I/O pins are connected using an programmable interconnect device. In the architecture disclosed, the I/O pins in each FPGA are divided into two groups: hardwired connections and programmable connections. The pins in the first group connect to other FPGAs and the pins in the second group connect to FPIDs. The FPGAs and FPIDs are interconnected using a partial crossbar architecture.

Abstract: The use of more than one field-programmable gate array design with a given logic capacity produces advantages over the use of a single field-programmable gate array design. The designs of the field-programmable gate arrays in the family are be selected so that each field-programmable gate array design advantageously implements a different type of circuit. This use can select from the family of FPGAs with the same logic capacity such that the circuits can on average be implemented faster and/or in a smaller area.

Abstract: An automatic vehicle headlamp intensity adjustement circuit includes a high sensor. A tuned rectifier circuit for producing a d.c. signal of magnitude dependent on the amplitude of the 50Hz (or other local supply frequency) component of the signal picked up by the sensor. A lamp current modulating circuit is controlled by this d.c. signal through the intermediary of an averaging circuit. The averaging circuit has a relatively long time constant and a timer is connected to reduce this time constant if the d.c. signal continues to fall for more than a predetermined period of time.
