Abstract: Techniques for managing data mobility domains in storage system environments. The techniques employ a multiple master approach, in which each storage system in a storage system domain can function as an owner of the domain. Each domain owner has privileges pertaining to addition of new members to the domain, removal of members from the domain, and modification of domain credentials. When a new storage system is added as a member of the domain, the domain credentials are provided from the domain owner to the new storage system, resulting in the domain credentials being shared among all members of the domain. Domain membership information is also shared among all members of the domain. In this way, the management of storage system domains can be achieved without the need of a domain management server, avoiding a single point of failure or latency and reducing the complexity/cost associated with the domain management server.

Abstract: A method of operating a wearable heads-up display that in use is worn on a head of a subject user includes projecting light to an eye of the subject user and detecting an ambient light condition in an environment of the wearable heads-up display by an ambient light sensor. The method includes measuring a pupil size of the eye of the subject user and determining a target luminous flux based on an output of the ambient light sensor and the pupil size. A current luminous flux of the light projected to the eye of the subject user is adjusted based on the target luminous flux.
Abstract: A method for providing control of surface waves propagating on a surface includes forming a surface treatment on the surface, wherein the surface treatment is configured to achieve a tensor surface admittance distribution matrix on the surface determined according to a modified transformation electromagnetics (tEM) equation.
Abstract: A system including a plurality of nodes. Each node includes a pending operations list, an unstable operations list, and a hardware controller. The pending operations list can include operations that have not yet been executed on the node. The unstable operations list can include operations that have not yet been stored on non-volatile data storage. Each of the operations listed in the unstable operations list can include a listing of all other operations that must be executed prior to the operation being executed on each respective node. The hardware controller can be configured to execute at least one operation listed in the pending operations list, remove at least one executed operation from the pending operations list, and remove at least one operation from the unstable operations list.
Abstract: A cluster management system sends a first message over a communications network to detect a server node which runs a base operating system image configured to communicate with the cluster management system to enable discovery and network configuration of the server node. In response to receiving the first message, the base operating system image sends a second message to the cluster management system, wherein the second message includes node identifying information associated with the server node. The cluster management system and the base operating system image communicate to configure network settings of the server node based on server cluster specifications and the node identifying information. Subsequent to completion of the network configuration, the cluster management system automatically provisions the server node for inclusion in a server cluster by re-imaging the server node with a server operating system to enable operation of the server node in the server cluster.

Abstract: Disclosed is a double chamber container. The first chamber comprises a stopper coupled to a first end and a cover coupled to a second end. The second chamber comprises a plunger coupled to one end and an open second end. The first chamber is coupled to the second chamber such that the first end of the first chamber is coupled to the second end of the second chamber.
Abstract: Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions. Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard ½-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system.

Abstract: Quality of Service (QoS) for Device Assisted Services (DAS) are provided. In some embodiments, QoS for DAS includes providing a wireless communications device configures to determine a QoS request for a service over a wireless network; and verify the QoS request for the service over the wireless network using one or more verification techniques.
Abstract: A lamp is provided that can have at least one interface on the lamp body for a selectable lumens and selectable correlated color temperature (CCT). In one embodiment, the lamp design includes a housing having a downlight geometry and a light engine including at least one string of light emitting diodes (LEDs), in which the light engine is position to emit light through a light emission end of the housing having the downlight geometry. The lamp also includes at least one first switch for selecting at least one lumen setting for the light emitted by the light engine; and at least one second switch for selecting at least one correlated color temperature. The first and second switch are mounted to the housing.

Abstract: Methods, devices, and systems for forming atomically precise structures are provided. In some embodiments, the methods, devices, and systems of the present disclosure utilize a scanning tunneling microscope (STM) system to receive a sample having a surface to be patterned. The system positions a conductive tip over a pixel region of the surface. While the conductive tip remains laterally fixed relative to the surface, the system applies a bias voltage between the conductive tip and the surface such that a current between the conductive tip and the surface removes at least one atom from the pixel region. The system stops applying the voltage and current when it senses the removal of the at least one atom. The system then verifies that the at least one atom has been removed from the pixel region.
