Publication number: 20240107568Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as an access point (AP), may perform a channel selection procedure that accounts for one or more sub-channels of a particular channel being punctured. For example, an AP may generate multiple channel efficiency metrics for multiple channels. The multiple channel efficiency metrics may be based on measuring the multiple channels and one or more subchannel puncturing patterns for the one or more channels of the multiple channels. The AP may transmit a message on a channel of the multiple channels based on a channel efficiency metric, of the multiple channel efficiency metrics, for the channel. The AP may transmit a control message including a puncture bitmap that indicates a subchannel puncturing pattern for one or more subchannels of the channel. The message may be transmitted on the channel in accordance with the puncture bitmap.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Venkateswara Swamy Bandaru, Krishna Chaitanya Rao, Neelakantan Nurani Krishnan

Patent number: 8774367Abstract: An X-ray tube for generating X-radiation includes a rotary structure having a rotating anode, a stationary structure for rotatably supporting the rotary structure, and a hydrodynamic bearing which is arranged between the rotary structure and the stationary structure. The bearing includes a gap between the rotary structure and the stationary structure, a stabilizer configured to stabilize dimensions of the gap with respect to distortions because of thermo-mechanical causes.Type: GrantFiled: October 19, 2009Date of Patent: July 8, 2014Assignee: Koninklijke Philips N.V.Inventors: Rolf Karl Otto Behling, Christoph Bathe, Michael Luebcke, Van-Minh Duong, Krishna Swamy

Patent number: 8564237Abstract: In an embodiment, a system includes: a casing for surrounding at least a portion of a rotor, and enclosing a volume of a cooling gas thereabout, the casing including a plurality of static seals; an end housing at each end of the casing, each end housing including a seal system through which the rotor extends, wherein a portion of cooling gas escapes from the casing to at least one seal area; and a source of cooling gas fluidly coupled to the casing by a cooling gas regulator. The system may further include: a scavenging system coupled to each end housing for removing a gas mixture therefrom including a portion of escaping cooling gas; a sensor for determining a purity of the cooling gas in the casing; and a static seal leak detector that generates an alarm indicative of a leak in at least one of the plurality of static seals.Type: GrantFiled: January 5, 2011Date of Patent: October 22, 2013Assignee: General Electric CompanyInventors: Vinodh Kumar Bandaru, Jeffrey James Andritz, James Daniel Antalek, Krishna Swamy Cherukuri, Daniel James Fitzmorris, Anthony James George, Nicola Piccirillo, Sudhanshu Rai
