  • Publication number: 20240071576
    Abstract: Approaches, techniques, and mechanisms are disclosed for predicting molecular electronic structural information. According to one embodiment, quantum simulation results are generated for a molecule based on a quantum simulation of an electronic structure of the molecule. The quantum simulation of the electronic structure of the molecule is performed with quantum processing units. An input vector comprising data field values derived from the quantum simulation results for the molecule is created. An electronic structural information prediction model is applied to generate, based at least in part on the input vector, predicted electronic structural information for the molecule.

  • Patent number: 8660988
    Abstract: A method for updating a block on disk is provided. The method involves one or more clients committing log records to queues corresponding to blocks. The method further involves checkpointing, which includes obtaining a flushing lock on the queue by a client, receiving log records from the queue, applying the log records to a block on disk, and deleting the log records from the queue. A block on disk may be updated by first applying the log records from a queue to a locally cached version of the block corresponding to the queue. The locally cached version may then be stored on the disk replacing the original block on disk or being stored as a new version of the original block.

  • Publication number: 20070248445
    Abstract: An interface between a hydraulic power system and an hydraulically actuated engagement member includes a first portion that is pivotally coupled to a second portion, and has an inlet capable of being coupled to the power system. The second portion is fixedly attached to an attachment bracket capable of interfacing with an attachment. The first portion has a path to provide oil to the second portion, which in turn provides oil from the first portion to the attachment bracket. The attachment bracket includes a housing that accepts an engagement member capable of being hydraulically actuated to secure or release the attachment with respect to the power machine.

  • Publication number: 20060117613
    Abstract: A wear assembly provided with a tapered opening and a complementary tapered lock wherein the lock can be pried into and from the opening to thereby eliminate the need for hammering. The lock is formed with a body and a latch that is movable between a hold position where the latch is engageable with a stop in the opening to releasably retain the lock in the opening and a release position where the latch disengages the stop.

  • Publication number: 20040110445
    Abstract: An Infant-Operable Remote Controlled Entertainment and Education Device and System is disclosed. Also disclosed is a system that includes a control device that is safe to be left with unsupervised infants. The system further includes a responder device that is in communication with the control device. The control device has a plurality of buttons or other touch-sensitive portions dispersed on its face, and each of these buttons has a unique shape or design displayed thereon. Correspondingly, the remote device includes a plurality of figures or members that have shapes or display designs that correspond to the buttons on the control device. In operation, touching or pressing one of the control buttons or touch-sensitive portions of the control device will cause one of the figures or members on the responder device to animate or otherwise agitate in response.

  • Patent number: 5563349
    Abstract: Disclosed is a diametral extensometer device useful for measuring diametral changes in a valve stem caused by axial loads on the valve stem used in a motor operated valve assembly. The device is useful in the field of valve diagnostics. The diametral extensometer is comprised of a semi-circular clamp member spaced from and partially surrounding the outer periphery of the valve stem. The clamp member has a reference pad that is adjustable radially with respect to the valve stem and a sensor pad having a sensor capable of measuring diametral changes in the valve stem and generating an electrical signal indicative of those changes. A stabilizer pad provides stability to the clamp member during installation of the clamp member and during movements of the valve stem. Non-stick surfaces are provided for smooth operation, and point contact with the valve stem eliminates errors associated with rocking of the traditional V-groove contacts.
