A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

A clutch for use in a gas turbine engine is disclosed herein. The clutch is adapted to selectively transmit rotation from a first shaft of the clutch to a second shaft of the clutch.

A wedge plate for a wedge clutch assembly for selectively engaging or disengaging an inner hub and an outer ring including first wedge plate segments arranged radially between the inner hub and outer ring, each of the first wedge plate segments including a first circumferentially extending groove and a first retaining element disposed in the first circumferentially extending groove and urging the first wedge plate segments radially inward to contact the inner hub.

A wedge clutch, including: a hub; a ring located radially outward of the hub; a wedge plate radially between the hub and the ring; and a displacement assembly including an element and an engagement arm. To transition from a disconnect mode for the wedge clutch, in which the hub and the ring are relatively rotatable, to a connect mode for the wedge clutch, the engagement arm is arranged to pivot in a first rotational direction to displace the hub in a first axial direction. To transition from the connect mode to the disconnect mode, the engagement arm is arranged to pivot in a second rotational direction, opposite the first rotational direction and the element is arranged to displace the hub in a second axial direction, opposite the first axial direction.

A wedge clutch, including: a shaft; a hub radially disposed about the shaft; an outer ring located radially outward of the hub; a wedge plate radially disposed between the hub and the outer ring; and a displacement assembly including a first element and a plunger assembly at least partly disposed within the hub. To transition from a disconnect mode to a connect mode, the displacement assembly is arranged to displace the hub in a second axial direction and a portion of the plunger assembly is arranged to displace radially inward to block axial displacement of the hub in the first axial direction. To transition from the connect mode to the disconnect mode, the portion of the plunger assembly is arranged to displace radially outward through the hub and the first element is arranged to displace the hub in the first axial direction.
