An assembly is provided for an aircraft propulsion system. This assembly includes a first actuator, a second actuator and a linkage system. The linkage system is configured to transfer torque between the first actuator and the second actuator. The linkage system includes a first linkage shaft, a second linkage shaft and a gearbox. The first linkage shaft has a first centerline. The second linkage shaft has a second centerline offset from the first centerline. The gearbox is coupled to and is between the first linkage shaft and the second linkage shaft.

A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

A massage system for a seat of a vehicle includes a drive motor, a sliding member having a hollow pillar shape, a first end of the sliding member being blocked by a plate member and a second end of the sliding member being opened, a housing member having a hollow pillar shape, a first end of the housing member being blocked by a partition and a second end of the housing member being opened, and a drive gear module operably connected to the drive motor, wherein at least one roller member is extended toward the housing member at an edge of the plate member, and at least one cam protruding toward the sliding member is formed at a circumference of the partition, wherein a cam profile is formed at a surface of the cam.

A digital display and a digital time device are provided, which includes a housing, a drive assembly, display assemblies and a mainboard assembly. The housing is provided with seven windows arranged to form the shape of the character “”. The mainboard assembly is fixedly connected to the housing and is located behind the windows. Seven curved grooves are provided inside of the drive assembly. The display assemblies include display sheets and pull rods. One end of each pull rod is fixedly connected to the display sheets. The display sheets are slidingly connected to the mainboard assembly. There are seven display assemblies. Each pull rod is slidingly connected to the curved grooves in one-to-one correspondence, and each display sheet is one-to-one correspondence with the windows. The present invention can achieve many advantages, such as low power consumption, great waterproof, strong moisture resistance capabilities and high stability.

A back cover ejection structure is applied in an electronic device. The electronic device includes a back cover and a middle frame, the back cover ejection structure can eject the back cover from the middle frame. The back cover ejection structure includes a housing, a moving plate, and a rotating cover. The moving plate is received in the housing and can move in a first direction. The moving plate includes a plate body and a first groove defined in the plate body. The first groove includes a first section, the first section inclined with the first direction. The rotating cover is rotatably connected to the housing. The rotating cover includes a sliding rod slidably received in the first section. The sliding rod can push the rotating cover to rotate when sliding in the first section, causing the rotating cover to eject the back cover from the middle frame.
