In some configurations, the headgear assembly includes one or more hubs, each of which are configured to connect a top and rear strap together. The size of the headgear assembly can be determined by the size or configuration of the hub. In other configurations, the headgear assembly comprises one or more spacer elements within one or more straps of the headgear. The size of the headgear assembly can be determined by the size of the spacer element or a relative position between the strap and the spacer element.

Abstract: Documents maintained by a first storage system that supports security groups are synchronized to a second storage system that supports group entities, which are incompatible with security groups. Permissions associated with the synchronized documents, including security groups, can be synchronized from the first storage system to the second storage system when a security group is created, when membership in a security group is modified, and when a security group is deleted. Synchronization of security groups in this manner can also be selectively enabled on a per-site basis or at another level of granularity.

Abstract: A system for enhancing personnel safety on a railroad track is presented. The system can receive data from sensors and/or a PTC system to determine positions of clients/worker and/or vehicles, and further utilize such data to determine if a vehicle is within a certain proximity of the client/worker location. The system can further generate geofences around clients/vehicles to and determine when such geofences intersect one another. Additionally, the present disclosure can assign severity levels and generate alerts with the assigned severity levels, and such severity levels can indicate how close a vehicle is to a particular location. It is an object of the invention to provide a system for generating alerts to notify personnel when they much retreat to a place of safety.

Abstract: A method for cooling a compressor section of a gas turbine engine includes sensing, via at least one first temperature sensor, a first temperature at the first location on a stationary assembly of the compressor section. The method also includes sensing, via at least one second temperature sensor, a second temperature at a second location on the stationary assembly of the compressor section. The second location is spaced apart from the first location. The method also includes determining, via a controller, a delta between the first temperature and the second temperature. Further, the method includes operating, via the controller, at least one cooling element when the delta exceeds a predetermined threshold, the at least one cooling element provided at the first location of the stationary assembly of the compressor section.

Abstract: Mitigating particulate intrusion to an air intake system of a gas turbine system with intrusion protective coatings tailored to locale of operation. A particulate intrusion protective coating is applied to a surface of a component of the air intake system to mitigate ingress of particulates within the air intake system and the gas turbine system. The particulate intrusion protective coating includes one or more particulate ingress influencing properties tailored to the common attributes of the particulates associated with the locale of operation of the gas turbine engine and the air intake system. The particulate ingress influencing properties affect rebounding and coalescing characteristics of the particulates at a point of impact with the applied surface having the particulate intrusion protective coating, entraining the particulates at the point of impact and inhibiting further ingress along an inlet air flow path of the air intake system into the gas turbine engine.

Abstract: A patient interface comprises a blower, a cushion for contacting a user's face, and a mask body and/or a frame for supporting the cushion on a user's face. The cushion and/or the mask body or frame define an interior space for receiving a flow of gases from the blower. The blower is mounted to the mask body or frame so that the blower is at least partially within the mask body or frame. The blower substantially separates a high pressure side of the mask body or frame from a low pressure side of the mask body or frame and/or the mask body or frame is substantially without a wall between the blower and the interior space.

Abstract: A method, apparatus, and computer readable storage to implement an augmented game system. A player can play an online game and accumulate loyalty points without have to pay cash. The player can enter a physical casino and play an electronic gaming machine which can retrieve the player's information from the online game including the number of loyalty points the player has and any other incentives or game add-ons the player would be entitled to. The player would then play a physical game on the electronic game normally (by depositing cash and playing) but the game play would be augmented by virtue of the player having the loyalty points or other incentives or add-ons. For example, the game can be augmented by giving the player a better paytable.
