A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.

A manual activation system includes a housing and a pulley arranged within the housing. The pulley is movable between an inactive position and an active position. A tension member is wrapped about the pulley and has a tensile force acting on the pulley. At least one link arm is rotatably mounted within the housing. The at least one link arm is operably coupled to the pulley to selectively oppose the tensile force acting on the pulley.

A quick release assembly has a linear U-shaped member with a base and slotted opposed sides. A nonlinear lever member positioned within the U-shaped member has an aperture aligned with the slots. A fastener through the lever aperture and both slots of the U-shaped member retains the lever member therein. The U-shaped member is fastened to the outer section of a telescoping device parallel with the linear axis thereof. A connector device of the lever member is fastened to a locking mechanism maintaining a movable inner section of the linear telescoping device. Applying force to the lever member opposite the attachment member pivots the lever member and releases the locking mechanism, thereby allowing the inner section of the telescoping device to extend from the outer section, with the lever member attached to the inner section moving along but maintained within the U-shaped member.

An adjusting device includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.

Systems for activating and deactivating an emergency landing gear system in an aircraft include a rotary toggle mechanism that actuates a switch. When the switch is actuated, the emergency landing gear system is activated and the operation of one or more other aircraft systems may be modified accordingly. The rotary toggle mechanism may be placed in three different states: a ready state, an active state, and a reset state. In the ready state, the switch is not actuated and the emergency landing gear system is not activated. In the active state the switch is actuated and the emergency landing gear system is activated. While the mechanism is in the active state the mechanism cannot be returned to the ready state without first passing through the reset state.
