  • Publication number: 20210101676
    Abstract: An annular spar for a ducted-rotor of an aircraft may be fabricated from composite material, such as carbon-fiber-reinforced plastic (CFRP). The spar may include an annular plate, a first circumferential flange that extends from an outer edge of the plate, and a second circumferential flange that extends from an inner edge of the plate. The first and second circumferential flanges may taper inwardly toward a center axis of the spar. The spar may be constructed of a plurality of layers of CFRP. One or more of the layers may be fabricated from a single ply of CFRP, and one or more other layers may be fabricated from a plurality of plies of CFRP. The spar may exhibit a coefficient of thermal expansion (CTE) that allows an associated tip gap to remain essentially constant throughout a range of operating temperatures.

  • Publication number: 20210102813
    Abstract: A worksite management system for a worksite includes a sensor module associated with each of one or more machines working on the worksite. The sensor module generates a signal indicative of a location of a corresponding one of a machine from the one or more machines. An on-board controller associated with each of the one or more machines receives the signal corresponding to the location of the corresponding one of the machine on the worksite, and looks up the location of the corresponding one of the machine in at least one of a pre-generated or learned terrain map of a network of haul routes. The on-board controller identifies at least one condition of the haul route at the looked-up location, and then generates an alert for an operator to perform one or more recommended actions with respect to an operating parameter of the corresponding one of the machine.

  • Patent number: 10956245
    Abstract: A storage system in one embodiment comprises a host processor, and a solid-state storage device coupled to the host processor and comprising a non-volatile memory and a storage controller. The host processor is configured to initiate an error scanning operation on a designated portion of the non-volatile memory by directing at least one read command to the storage controller. The read command is configured to indicate to the storage controller that data read from the non-volatile memory responsive to the read command is not to be returned to the host processor. For example, the read command may illustratively comprise a Scatter Gather List (SGL) bit bucket descriptor indicating that the data read from the non-volatile memory responsive to the read command is to be discarded rather than returned to the host processor. The storage controller records any detected errors in a media error log and notifies the host processor of such errors.

  • Patent number: 10940846
    Abstract: An electromechanical brake assist system driven by an electric motor cooperating with a master cylinder and having, along the axis of actuation, a helper piston in the shape of an axial sleeve solidly connected with a guide bracket and having a threaded surface. A nut, fixed in translation but free to rotate, has interior threads that complement those of the helper piston, which it receives, and exterior teeth that cooperate with the drive motor. A plunger piston carries a drive base so it can be pushed by the piston. Its other extremity is connected to the control rod, formed from a body and a head. The body has a crimping area and the head has a sleeve with an extremity that can be crimped along the crimping area.
