Abstract: A control system that mitigates stick-slip vibrations at higher harmonics than currently available is disclosed. A controller of a top drive is set to a torque control mode instead of a speed control mode. The controller receives torque measurements and compares to a target torque value. The controller accelerates or decelerates the top drive by a generated current adjustment command. A slow integration speed control loop, at least an order of magnitude slower in response than the torque control loop, receives a RPM set point. The slow integration speed control loop compares the RPM set point to an actual RPM measurement and generates a torque command. The torque command is sent to the torque control loop which results in an acceleration or deceleration of the top drive to maintain a desired torque amount. The speed of the top drive is bounded by a speed limit control loop.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for creating an application-aware snapshot of a storage volume. A network association module is configured to determine an owner for a storage volume. A requester module is configured to request a snapshot operation for a storage volume. A snapshot operation may be initiated from a storage appliance. A provider module is configured to create a snapshot of data of a storage volume in a storage appliance in response to a determined owner quiescing activity for the storage volume.

Abstract: A micro grid for an oil field is powered by a utility power grid. A micro grid controller is adapted to prevent excessive or unstable power draw on the utility power grid while allowing uninterrupted power supply for drilling rigs in the oil field. The micro grid controller is adapted to control operation of one or more pieces of electrical equipment on the drilling rigs. The micro grid controller may prioritize operation of the electrical equipment based on relative priority of the operations or based on an operating condition of the drilling rig.

Abstract: Various embodiments of the present invention pertain to methods for biological production of hydrogen. More specifically, embodiments of the present invention pertain to a modular energy system and related methods for producing hydrogen using organic waste as a feed stock.

Abstract: Methods and systems for detection of a status of a device connected to a USB port of a UPS are described herein. The method includes detecting whether a device is connected to the USB port, based on the detection, receiving, at the UPS, information from the device; determining whether the device is configured as a host device supplying power, a host device requiring power or a peripheral device, and based on the determination, configuring the USB port of the UPS.

Abstract: Methods and systems are described for a media guidance application that enhances the viewing experiences of users consuming a sequence of media. In particular, the media guidance application may enhance the viewing experiences of users consuming a sequence of media by removing portions of redundant media that were previously consumed by the user.

Abstract: A publication-and-subscription mechanism for team rooms, referred to as team room “channels”, through which teams are able to selectively share resources from their team rooms with non-members, and that allows selective contributions, modifications, and discussions from non-members. The team room channels operate as bidirectional information pipelines to other team rooms. The team room channels may either be broadcast to all known teams, or be published selectively to one or more designated “target” teams. The receiving team rooms may then subscribe to specific published channels as appropriate. Information items from a team's team room, such as documents, tasks, representations of team members, and/or other resources, may be added to one or more of a team's published channels. Teams can associate specific permissions with each channel, including Read, Contribute, Modify, and/or Discuss. These permissions apply to all items associated with the channel.

Abstract: A system and method for reducing an electrical load in a facility or building with an automated demand response server having a hierarchical grouping of demand stages and demand groups with associated timers that control the shedding of load in order to achieve the appropriate level of load reduction and ramping up devices in a controlled manner upon the expiration of a demand response event.

Abstract: A chat user interface for threaded text chat systems. The user interface can include a canvas view in which multiple portions of a threaded text tree for a chat session can be rendered separately and concurrently. The user interface further can include a chat participant view, a chat input view and an outline view of an ongoing chat session. Notably, selections of a threaded text tree rendered in the canvas view can be configured for zooming so that certain parts of the threaded text tree can be viewed more readily than other parts of the threaded text tree. Moreover, as new text entries are provided to any branch of the threaded text tree, visual indicators can be activated in the canvas view to alert an end user to the location of the new text entries. Finally, the canvas view can accommodate both imported external objects, such as graphics or links to Web pages, and also a white board region into which notations can be applied by an end user during the course of a chat session.

Abstract: The present invention is directed to systems and method for predicting risk of AMD or a susceptibility to AMD in a patient by detecting elevated serum or plasma levels of C3, CFB or CFH and other complement factor polypeptides, wherein devated levels certain complement factors, genetic risk factors, medical risk factors, behavioral and environmental risk factors are associated with are indicative of susceptibility for or an increased risk of developing AMD, or an increased risk of progression of AMD in the patient.

Abstract: A system and process for reclaiming nickel and cadmium from a feed source such as Ni—Cd batteries. The feed source is shredded to produce feed particles, screened to size the particles, magnetically separated to remove non-metallic materials, and induction heated to generate nickel and cadmium products.

Abstract: An address resolver system that assists a node in an IPv6 network to select an address for connectivity with a node in an IPv4 network when both DSTM and NAT-PT transition mechanisms are available. Native connectivity can be achieved by preferring an encapsulation or tunnelling mechanism such as DSTM where possible over a translation mechanism such as NAT-PT. A range of encapsulation and translation mechanisms are envisaged. The resolver determines capabilities of the node and of the application that requires the address in order to make the selection.

Abstract: A chiller apparatus is disclosed. The chiller apparatus comprises a revolving drum, a cooling system, and a baffle assembly. The revolving drum includes a flight assembly that is continuously welded throughout the revolving drum for moving a product from an infeed end of the revolving drum to a discharge end. The cooling system is coupled to the revolving drum for supplying a cooled fluid to the revolving drum. The baffle assembly includes a plurality of triangular baffles seal welded to the inside of the revolving drum and to the flight assembly for turning the product. The seal weld formed between the baffle assembly, the flight assembly, and the revolving drum prevents the cooled fluid from forming stagnation points that contaminate the product.

Abstract: A manifolded fail-safe hydraulic control system provides fail-safe operation of a pipeline valve using no more than a total of 45 proprietary parts in the system. The system controls the operation of a spring return actuator, which in turn strokes the pipeline valve from the normal operating position to the fail-safe position, or from the fail-safe position to the normal operating position. The system enables the valve to automatically stroke to its fail-safe position without external power.
