  • Patent number: 11966816
    Abstract: Aspects of generating error-resistant quantum control pulses from geometrical curves are described. In some embodiments, a closed space curve is parameterized for a target gate operation of a quantum computing device. The closed space curve corresponds to an evolution operator of a time-dependent Schrödinger equation associated with the target gate operation. A control field definition is identified for the target gate operation based at least in part on a geometrical analysis of the evolution operator of the time-dependent Schrödinger equation. The target gate operation is implemented for the quantum computing device based on the control field definition.

  • Patent number: 9700016
    Abstract: Described herein is a marking system for marking animals. The marking system may include a restraining device, a controller, and a marking device. The marking device includes a marking needle of fixed length comprising one or a plurality of needle tips; the restraining device is sized and configured for restraining an animal or animal body part thereof and oriented such that the marking device can make a mark on a substrate portion of the animal body part; and the controller is configured to control the position of the marking device and to make a mark on the substrate portion of the animal body part. Also described herein are media transfer assemblies for use in the disclosed marking system.

  • Patent number: 9280482
    Abstract: The present invention relates to a method of optimizing the provisioning of a bootable image onto a storage device. In some embodiments, a host device executes a provisioning application to image a storage drive as a bootable drive. During the provisioning process, the storage device is configured to disguise its use of write caching during the provisioning process. In one embodiment, the storage device is configured to suppress forced unit access commands and cache flush commands for the provisioning application. In another embodiment, the storage device is configured to reject forced unit access commands. The storage device may disguise its use of write caching based on various criteria, such as a length of time, a counter, and the like.

  • Patent number: 5373931
    Abstract: An integrally formed conveyor belt cleaning head (10) formed of a resilient material includes a substantially transversely extending cleaning tip portion (11). At least two integrally formed and substantially parallel, integrally spaced apart elongate arms (12) extend outwardly therefrom, substantially perpendicular to the transverse cleaning tip portion (11). The arms (12) extend into a substantially transverse base portion (14) which is adapted to engage with and/or be mounted to resilient mounting pad (18). Elongate reinforcing shoulders (19) extend at least partway along each of the arms (12).

  • Patent number: 5031750
    Abstract: A cleaning arrangement for a conveyor comprises an elongated beam forming a liquid reservoir and being connectable to a source of liquid. The beam is mountable transversely below a conveyor belt. The beam mounts a scraper device and is provided with a plurality of liquid nozzles along the length thereof. The nozzles are in communication with the liquid reservoir. A deflector extends downwardly from the scraper device and is so formed and provided that liquid from the nozzles passes therethrough and on to an adjacent surface of the conveyor belt at a position adjacent to and immediately before or substantially simultaneously with contact between the conveyor belt and the scraper device.
