  • Publication number: 20220210498
    Abstract: An archive model can be used for managing networked storage of recorded content, such as network DVR (digital video recorder) content. Content may be initially recorded to an active storage device, with individual duplicate copies recorded for each requesting user, and subsequently archived to an archive storage device. For playback, the content can be reconstituted into the active storage device prior to delivery to the requesting user. Content can be predictively reconstituted in anticipation of user needs, and the reconstitution capacity of the system can be dynamically reallocated for load balancing.

  • Publication number: 20220181934
    Abstract: A rotor hub assembly includes a rotor hub, a rotor and a cooling sleeve surrounding the rotor hub and located between the rotor hub and the rotor. Coolant flows between the rotor hub and the rotor during spinning of the rotor hub assembly. The cooling sleeve may include channels formed in the inner surface. The rotor hub may include an annular channel in fluid communication with the cooling sleeve channels. The annular channel may include apertures such that the cavities in the rotor hub are in fluid communication with the cooling sleeve. Coolant circulating within the rotor hub enters the annular channel and the channels in the cooling sleeve from centrifugal force caused by spinning of the rotor hub assembly.

  • Publication number: 20210405964
    Abstract: A framework for generating and presenting verbal command suggestions to facilitate discoverability of commands capable of being understood and support users exploring available commands. A target associated with a direct-manipulation input is received from a user via a multimodal user interface. A set of operations relevant to the target is selected and verbal command suggestions relevant to the selected set of operations and the determined target are generated. At least a portion of the generated verbal command suggestions is provided for presentation in association with the multimodal user interface in one of three interface variants: one that presents command suggestions as a list, one that presents command suggestions using contextual overlay windows, and one that presents command suggestions embedded within the interface. Each of the proposed interface variants facilitates user awareness of verbal commands that are capable of being executed and teaches users how available verbal commands can be invoked.

  • Patent number: 11156053
    Abstract: A riser disconnect/reconnect system having a disconnection package (RDP) and a modified lower marine riser package (LMRP) are provided for quick disconnection of the marine drilling riser (MDR) from the LMRP to facilitate access to the LMRP or BOP stack. The RDP includes a flex joint and a hydraulically-actuated release connector (RC) with a connecting mandrel that engages a modified LMRP. In an emergency, the RDP is disconnected from the LMRP allowing access to the BOP stack for intervention. The RDP may be disconnected from the LMRP for recovery of the LMRP or BOP stack to the surface for repair or maintenance without recovering the MDR. The RC joins the flex joint to the uppermost annular blowout preventer in the LMRP. The release connector can be used in a standard or inverted position. Also provided are structural cages with complementary stab plates allowing access to various bypass ports and controls.

  • Publication number: 20210328221
    Abstract: The present disclosure provides a dispersible graphene platelet and a method of making same. The structure of the graphene platelet 10 comprises a base layer 1 of graphene on which at least one discontinuous layer 2, 3, 4 of graphene is stacked, with each layer of graphene above the base layer having a smaller surface area than the layer it is stacked upon. The edges of the base layer and the discontinuous layers stacked upon it are all at least partially functionalised 5, providing a structure with graphene-like properties owing to the base layer and relatively high dispersibility owing to the increased amount of functionalised groups on each platelet. The platelets may be used for a number of applications, for example in the production of electrodes or composite materials.

  • Publication number: 20210173365
    Abstract: A method for analytics in heating, ventilation, and air conditioning (HVAC) is described. Operation of an air-handling unit in an HVAC system is measured, including fan speed, pressure, power input, and flow. The measurements are transmitted to a processor, which analyzes the operation of the air-handling unit. The analysis includes optimizing a heuristic model of air handling in the HVAC system based on a combination of two or more of the fan speed, pressure, power input, or flow, and determining, based on the optimized heuristic model, a diversity from a fan flow set point and a fan designed maximum flow. A display presents an indication of a mismatch of a fan with a space based on the diversity.

  • Publication number: 20210166585
    Abstract: Systems and methods are provided for creating printed tags for use in connection with a heated food item placed into a hot holding unit. System components may include a user interface, a printer, and a controller. The controller is programmed to instruct the user interface to display a prompt for an operator to input information identifying one or more characteristics of a food item positioned within or to be placed into a hot holding unit. The controller receives the information from the user interface and instructs the printer to generate a tag identifying the food item and the time at which the food item is to be removed from the hot holding unit and discarded. The tag may include a display area to display the printed information and a support area with a slit that allows the tag to be supported by a rack of the hot holding unit.

  • Patent number: 10935944
    Abstract: Methods for modeling heating, ventilation, and air conditioning (HVAC) are described. A heuristic model of air handling in a HVAC system is optimized by a server based on measurements from outdoor sensors, from building space sensors, plant sensors, and sensors for the air handling. Settings of the air handling in the HVAC system are determined by the server from the model as optimized and transmitted to the HVAC system. The heuristic model may be optimized by indicating a mismatch of a fan with a space based on a diversity from a fan flow set point and a fan designed maximum flow; identifying a rogue zone or a critical zone of air handling units based on a number of actuator re-positioning, box pressures, and box flow; and/or determining a coupling of a coupled zone operation with temperature, flow, or temperature and flow.

  • Publication number: 20200366706
    Abstract: In an embodiment, a security auditing component obtains a solution set that is based upon a security audit of an enterprise network, the solution set characterizing a set of solutions associated with a set of security issues associated with one or more assets of the enterprise network, detects that the solution set can be condensed into a condensed solution set that mitigates the set of security issues to the same degree as the solution set, the detection being based at least in part upon (i) one or more rules applied to one or more solution texts and/or (ii) asset-specific metadata and/or (iii) static metadata, and condenses, based on the detecting, the solution set into the condensed solution set by combining two or more subsets of related solutions and/or filtering the solution set to remove one or more subsets of redundant or superseded solutions.

  • Publication number: 20200315497
    Abstract: An apparatus, and the method of using it, comprising one, or more, electronic sensors attached to a part(s) of a human or animal's body. The patient then performs an activity, or has an activity performed on them, and the results of the measured parameters are recorded by the sensor and processed, or downloaded and processed. The sensor may include a range of instrumentation, e.g. accelerometers, magnetometers, gyroscopes, force sensors, etc. to record positions (in the X, Y and Z planes), movements, angular movements, forces, stresses in bones/joints, etc. The use of the apparatus and method are appropriate to medical treatments, and perfecting sporting or dancing techniques and the results are processed to give the clinician or coach appropriate information to improve the problem being addressed. Methods for measuring lateral angular movement of hinged joints and spinal extension are taught.
