Abstract: Systems and methods for determining the health of a seal in a tire inflation system are provided. In one example, a method of determining the health of a seal of a tire inflation system on a vehicle includes obtaining one or more pressure measurements of a tire of the vehicle with a pressure transducer in communication with an electronic control unit and sending the one or more pressure measurements to a computer network via a communication network that receives signals from the electronic control unit, the communication network including a telematics device in communication with the computer network, wherein the computer network is configured to determine the health of the seal based on the one or more pressure measurements communicated by the telematics device.

Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.

Abstract: The present invention relates to a scraper (14) for scraping a surface of a machine tool having a wear-indicating device (18, 20, 24, 30) for the scraper lip (16) of the scraper. At least one signal line (18) is embedded in the scraper lip (16) in such a manner that, upon reaching the wear limit (G), at least one section of the signal line (18) is exposed.

Abstract: A sealing strip for sealing a suction zone of a suctioned roll of a machine for producing and/or processing a fibrous web has wear volume, which is gradually worn away by tribological contact with the roll. The sealing strip system further includes a sensor system for detecting the state of wear of the sealing strip, and an evaluation unit. The sensor system is embedded in a sensor channel extending within the sealing strip in the longitudinal direction at the wear volume across substantially the entire length of a sealing surface of strip, and is connectable to the evaluation unit and/or to a unit for supplying the sensor system with a medium for generating information via a connection provided on the lower side of the sealing strip, and leading out of the strip on the side of the wear volume facing away from the sealing surface.

Abstract: A sealing assembly including an elastic seal lip having a movable part is provided. The seal lip is configured to be attached to a first part of a machine and to be in contact with a second part of the machine. At least one acceleration sensor is fixed to the movable part of the seal lip, and that assembly further includes a data processing device for processing data obtained from the acceleration sensor. The data processing device is configured to determine the orientation of the acceleration sensor in relation to the direction of gravity.

Abstract: A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.
