Abstract: Approaches presented herein relate to the reservation and management of activity times available to perform activities, such as tee times, or other items included in an inventory, which may be bought, sold, or offered for sale. The reserved times may be electronically monitored and managed, such as in a tee time sheet including tee time details, to complete requests by users to transact the tee times. Electronic tokens may be created for each reserved time. Transactions can include listing the reserved time for sale, purchasing a listed time, submitting an offer to buy unlisted time, purchasing an unlisted tee time, and delisting a time. Additional services, such as guarantees and upselling, may be offered to a user when requesting a transaction.

Abstract: A flexible patient interface structure includes a posterior portion with at least one thin flexible membrane configured to form a seal with the patient's face in use. A wall thickness of the posterior portion is varied. An anterior portion of the flexible patient interface forms a chamber with the posterior portion and has a central gas washout vent region. A wall thickness of the anterior portion is thicker at the central gas washout vent region than at other adjacent regions. First and second laterally extending protrusions are configured to receive the breathable gas from an air delivery tube or air delivery tube connector. The central gas washout vent region is located between the first and second laterally extending protrusions and comprises an array of vent openings. Each of the first and second laterally extending protrusions terminates at a distal end that is furthest from the other laterally extending protrusion.

Abstract: Described techniques relate to improved methods, systems, devices, and apparatuses that support predictive assessments of vendor risk. The described techniques provide for machine learning and modeling to produce predictive risk profiles for vendors (e.g., even without security profile data provided by the vendor). Various described techniques may also produce unique insights across an entire portfolio of third parties using instant, predictive risk assessment results. Predictive risk profiles predict how a given vendor will answer each question in a standardized assessment based on one or more parameters (e.g., firmographics), both outside-in data and inside-out data, and similar completed assessments stored on an exchange associated with the system.

Abstract: This disclosure describes techniques for providing instructions when receiving biometric data associated with a user. For instance, a device may detect a portion of a user, such as a hand. The device may then display a first graphical element indicating a target location for placing the portion of the user above the user-recognition device. Additionally, the device may determine locations of the portion of the user above the device. The device may then display a second graphical element indicating the locations, such as when the locations are not proximate to the target location. Additionally, the device may display instructions for moving the portion of the user to the target location. Based on detecting that the location of the portion of the user is proximate to the target location, the device may send data representing the portion of the user to a remote system.

Abstract: Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

Abstract: An engine parameter estimation tuning system includes an engine parameter estimator unit and a gas path analysis (GPA) unit. The engine parameter estimator unit includes an onboard model (OBM) configured to output estimated parameters based on operation of a gas turbine engine. The gas path analysis (GPA) unit includes a performance health monitor unit configured to adjust a long-term deterioration parameter independently from adjustment of a short-term tuning parameter to tune one or more targeted estimation parameters included in the estimated engine parameter. In this manner, the engine parameter estimation tuning system can realize the different time scales associated with uncertainties in an engine and accommodate them separately so that the estimated engine parameters become much more accurate.
