Abstract: Proactively identify cable network impairments based on telemetry data from customer-premises equipment (CPE) devices is disclosed. In some embodiments, a maintenance service retrieves telemetry parameters from CPE devices at a customer site communicatively coupled to a cable network infrastructure. The maintenance service analyzes the telemetry parameters to detect cable network impairments experienced by the CPE devices at the customer site (based on, e.g., whether a telemetry parameter from any CPE devices fails a corresponding telemetry threshold, whether the same telemetry failure is experienced by all CPE devices at the customer site, whether other neighboring customer sites also experience the same failure on all CPE devices, and/or whether a high post main tap (HPMT) parameter and an HPMT magnitude (HPMTM) parameter for the customer site fail corresponding thresholds, according to some embodiments).

Abstract: A spark prevention cap is disclosed. The cap forms a sealed cavity around an end of a fastener protruding from a surface of a structure, for example, an aircraft structure. The cap has a cap body with an annular base terminating at a rim. The rim surrounds an opening into a central cavity for receiving the end of the fastener. The annular base has an external circumferential surface extending from the base rim, and a mating feature on the external circumferential surface configured to contact a sealant material applied externally to the cap.

Abstract: A pilot burner for a combustor includes an inner conduit configured to deliver a fuel, and an outer conduit concentric with the inner conduit and configured to deliver air. An inner wall defines an inner plenum, and a partition wall is radially outward of the inner wall and defines an intermediate plenum with at least a portion of the inner wall. Exit passages fluidly couple the inner plenum to the intermediate plenum. An outer wall defines an outer plenum with at least a portion of the partition wall. A crossover section includes passages fluidly coupling the inner conduit to the outer plenum, and passages fluidly coupling the outer conduit to the inner plenum. An end plate includes openings to direct fuel, air for combustion, and air for cooling from the respective plenums.

Abstract: A cap for forming a sealed cavity around an end of a fastener is disclosed. The cap has a cap body with an annular base terminating at a base rim which surrounds an opening into a central cavity. The cap also has an annular skirt providing an annular pocket between the skirt and the base. An inlet hole is provided in the skirt which is in fluid communication with the annular pocket. A protuberance protrudes in the annular pocket and faces the inlet hole to promote a flow of sealant injected through the inlet hole to flow annularly around the annular pocket.

Abstract: A cap for forming a sealed cavity around an end of a fastener protruding from a surface of a structure is disclosed. The disclosure relates to a spark prevention cap. The cap has an annular base with an annular base terminating at a base rim. The base rim surrounds an opening into a central cavity for receiving the end of the fastener. The base rim lies in a base rim plane around at least a majority of a circumference of the annular base. An annular skirt provides an annular pocket in which a sealant material is received. A biasing configuration is configured to positively bias the base rim against the surface of the structure.

Abstract: A fence straining element includes a post, attachment elements to attach a fence to the post, connection elements whereby in use the post is connected to a fence post. The connection is in a manner that allows the post to be rotated in a plane transverse to the longitudinal axis of the post. Rotation elements are provided whereby the post may be rotated to tighten, or loosen the fence attached thereto. Lock elements are also provided whereby the post may be locked, in use, in at least the position with the fence under some tension.

Abstract: A trim component (10) for a vehicle door post (11) having a seat belt mounting (17) secured thereto, the component comprising a body shell (12) with at least one energy absorbing member (24) mounted on the reverse side (16) of the body shell. The member (24) has an aperture (34) therein through which seat belt webbing (19) in use passes, and is slidable relative to the shell (12) to accommodate belt path adjustments.

Abstract: An airbag housing assembly for the passenger compartment of a motor vehicle is described in which a flexible strap (7, 107) is provided to attach a trim member (30, T) to a structural part (42, B) of the vehicle. The strap (7, 107) prevents the trim member (30, T) from becoming completely detached from the structural part (42, B) upon deployment of an airbag "A" housed between the trim panel (30, T) and the structural part (42, B).
