Abstract:
Systems and methods that facilitate on-chip testing are provided. An integrated circuit can include a transmitter configured to transmit a communications signal via a communications channel. The integrated circuit can also include a receiver configured to receive the communications signal via the communications channel. A jitter creation module also can form part of the integrated circuit and can introduce jitter into the system thereby allowing for on-chip jitter testing. The jitter creation module can form either part of the transmitter or receiver and can introduce the jitter by phase interpolation.
Abstract:
Techniques for identifying and organizing electronic messages are described. With some embodiments, a method receives a user interaction update from a messaging client associated with a first user. The user interaction update has data indicating that the first user interacted with an electronic message. The method may then determine that the first user is associated with a classification attribute that defines a relationship in a social network. Using the user interaction update, the a social classification rule corresponding to the classification attribute associated with the first user is then updated. The social classification rule may include data usable to organize a plurality of electronic messages. Finally, the method may optionally send the updated social classification rule to a messaging client associated with a second user, where the updated social classification rule can be used to organize electronic messages displayed by the messaging client associated with the second user.
Abstract:
A drilling system for drilling vertical holes in a mine roof includes a chuck configured to be driven in rotation by a motorized drill head. The chuck is cylindrical has a bore having a first polygonal inside perimeter. A drill member has an elongated hollow body with a cross section defining a circular outside perimeter over most of its length and a constant, second polygonal inside perimeter along substantially the entire length of the drill member. The drill member has at least one end region having a first polygonal outside perimeter that is sized to fit into the first polygonal inside perimeter to rotationally engage the drill member with the chuck. Drill bits having a bit fixture having a cross section with a second polygonal outside perimeter are sized and configured to fit snugly inside the second polygonal inside perimeter to be mounted to the drill member opposite the chuck.
Abstract:
A handlebar grip capable of combining with or without an auxiliary handle is disclosed. Four first tongue plates in an annular arrangement extend from a main grip. There is a gap between two adjacent first tongue plates. Each first tongue plate has a first rib extending therefrom. A cap having second tongue plates corresponding to the first tongue plates is fixed on the outer end of the main grip by interlacing the tongue plates. A hitching ring is sandwiched between the cap and main grip to form an extended portion of the main grip. Each the second tongue plate has a second rib, which connects the first ribs to form an annular rib with the first ribs. The ring has an annular groove to receiving the annular rib and to engage the main grip and cap. The ring may be changed into a horn shape as an auxiliary handle.
Abstract:
A key management system includes secured data stored on a first system secured by a control key stored securely on a key server. The secured data is secured against attacks such as unauthorized use, modification or access, where authorization to access the secured data is determined by knowledge of an access private key of an access key pair. When an authorized user is to access the secured data, the first system generates a request to the key server, signed with the access private key, wherein the request is for a decryption control key and the request includes a one-time public key of a key pair generated by the first system for the request. The first system can decrypt the decryption control key from the response, using a one-time private key. The first system can then decrypt the secured data with the decryption control key remaining secured in transport.
Abstract:
A method of parametric group processing includes forming a parametric index from an indexed database. A first parametric group and a second parametric group corresponding to elements in the parametric index are specified. The first parametric group and the second parametric group are merged to produce a merged parametric group. A parametric result is extracted from the merged parametric group, where the parametric result specifies a set of documents.
Abstract:
A magnetic recording medium having a substrate, an interlayer and a magnetic layer, the interlayer having at least a first intermediary layer, a second intermediary layer and a third intermediary layer, wherein the first intermediary layer or the third intermediary layer is non-magnetic or magnetic and the second intermediary layer has a hexagonal close pack crystal structure and a property of providing RKKY coupling between the first intermediary layer and the third intermediary layer when the first intermediary layer and the second intermediary layer are magnetic layers is disclosed.
Abstract:
Processes locally repairing a thermal barrier coating system on a turbine component that has suffered localized spallation includes locally cleaning a spalled region with water to remove spallation from the spalled region and form a tapered profile in the existing thermal barrier coating; and locally thermally spraying a powder mixture into the cleaned localized spalled region to form a repaired thermal barrier coating. Also disclosed herein are repair processes for platforms of bucket turbine engine components.
Abstract:
Semi-synthetic glycopeptides that have antibacterial activity are based on modifications of the desmethyl-vancomycin scaffold, in particular, acylation of the amino substituent on the amino-substituted sugar moiety on this scaffold with certain acyl groups; and/or conversion of the acid moiety on the macrocyclic ring of this scaffolds to certain substituted amides. In addition, compounds of the invention include desmethyl-vancomycin scaffolds on which the acid moiety on the macrocyclic ring is converted to certain substituted amides and the amino substituent on the amino-substituted sugar moiety is alkylated with certain alkyl groups. Also provided are methods for synthesis of the compounds, pharmaceutical compositions containing the compounds, and methods of use of the compounds for the treatment and/or prophylaxis of diseases, especially bacterial infections.
Abstract:
The present invention provides a specialized shipping container for transporting a fully assembled personal vehicle. After use, the shipping container is easily transformed into one or more alternative trailer configurations by rearrangement of the container components.
