摘要： A multi-mode aircraft power-split-transmission system includes a rotational power input and a power-split transmission. The power-split transmission includes a sun gear, a planetary carrier, a ring gear, a first rotational power output, and a second rotational power output. The multi-mode aircraft power-split-transmission system also includes a first resistance device coupled to the first rotational power output and fixed to an airframe of the multi-mode aircraft and a second resistance device coupled to the second rotational power output and fixed to the airframe. Operation of the first resistance device causes power received from the rotational power input to be directed to the second rotational power output.

摘要： A footwear system can employ a brake and/or a clutch, such as a one-way clutch, to convert human motion into usable electricity. The brake and one-way clutch can be used together, such as on opposite ends of a spring. During a storage phase, the brake can be engaged and the one-way clutch disengaged so the spring stores an energy. After the storage phase, the brake can be removed to initiate the release phase since the brake is not stopping the spring, but the one-way clutch allows the stored energy to be released.

摘要： A variable-speed speed-up mechanism (1) includes an electric device (50) and a transmission device (10). In the transmission (10), an internal gear carrier shaft (37) forms a constant-speed input shaft (Ac), and a planetary gear carrier shaft (27) forms a variable-speed input shaft (Av). The electric device (50) includes a constant-speed electric motor (51) having a constant-speed rotor (52) which is configured to rotate the constant-speed input shaft (Ac), and a variable-speed electric motor (71) having a variable-speed rotor (72) which is connected to the variable-speed input shaft (Ac). The variable-speed speed-up mechanism (1) further includes a brake mechanism (200) which is configured to detect an abnormal state of the variable-speed electric motor (71), stop the rotation of at least one of the variable-speed input shaft (Ac) and the variable-speed rotor (72), and continue the rotation of the constant-speed rotor (52).

摘要： A first planetary gear set includes a first sun gear to which power is input from a hydraulic motor. The first planetary gear set includes a first carrier and a first ring gear. The first carrier and the first ring gear are able to rotate in conjunction with rotation of the first sun gear. A second planetary gear set includes a second sun gear configured so as to rotate integrally with the first carrier. A hydraulic clutch mechanism allows or prohibits the rotation of the first ring gear.
