Abstract: An altimeter apparatus for an aircraft includes an altimeter circuit and can use a method of determining altitude. The method includes receiving a first signal in a first band via a first receive antenna, and receiving a second signal in a second band via a second receive antenna. The first band is a C-Band and the second band is at least one of a W-Band, Ku-Band, Ka-Band, V-band, or K-Band. The method also includes providing an altitude in response to the first signal or the second signal.

Abstract: A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter and encircles the rotation axis, wherein, along the entire inner diameter of the shroud body, the inner diameter leg is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

Abstract: In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.

Abstract: A telescopic leaf blower extension apparatus for extending a leaf blower hose includes a proximal tube that is configured to attach to a flex tube of a leaf blower. A distal tube is coupled to the proximal tube. The distal tube is telescopably coupled to the proximal tube. The distal tube has a retracted position within the proximal tube and an alternate extended position. A clamp means is coupled to the proximal tube and is selectively engageable with the distal tube to prevent the distal tube from moving between the retracted position and the alternate extended position.

Abstract: In accordance with one aspect of the present disclosure, a wear ring assembly is provided for a railway roller bearing. The wear ring assembly includes a wear ring having a central opening for receiving a journal of a railway wheel assembly and an insert including a plurality of spacers configured to extend in the opening of the wear ring to separate the wear ring from the journal. The spacers are spaced apart from each other about the wear ring. The insert may include one or more flanges that separate the wear ring from a bearing cone. The insert may be easily installed in the opening of the wear ring and separate the wear ring from the journal and the bearing cone to reduce fretting wear between the components.

Abstract: A particular activity performed by a particular user of a computing device is identified, for instance, by an agent installed on the computing device. It is determined that the particular activity qualifies as a particular use violation in a plurality of pre-defined use violations. A behavioral risk score for the particular score for the user is determined based at least in part on the determination that the particular activity of the particular user qualifies as a particular use violation. Determining that the particular activity qualifies as a particular use violation can include determining that the particular activity violates a particular rule or event trigger corresponding to a particular pre-defined use violation.

Abstract: A predetermined particular behavioral profile is identified associated with at least one particular user of a computing system, the particular behavioral profile identifying expected behavior of the at least one user within the computing system. Activities associated with use of the computing system by the particular user are identified and it is determined whether the identified activities correlate with the particular behavioral profile. Identifying an activity that deviates from the particular behavioral profile beyond a particular threshold triggers a risk event relating to the particular user.
