A cable sleeve comprises a housing, a locking cam, and a locking pawl. The housing has an elongate member passage configured to slidably receive an elongate member and has a cavity. The locking cam and the locking pawl are pivotally connected to the housing within the cavity. The locking cam has a radial edge with a constant radius relative to a pivot connection between the locking cam and the housing and is configured to move from a first cam position to a second cam position configured to engage the elongate member in the elongate member passage with the radial edge. The locking pawl is configured to move from a first pawl position to a second pawl position configured to move the locking cam into the second cam position to engage the elongate member.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetic flux interaction that, in effect, may provide a tunable resistance to movement, changing the rate of relative movement between the members. In one embodiment, the device comprises a first member in a kinematic relationship with at least one further member to form a system. The system moves within a limited range of motion and the system interacts when an external energizing force is imposed on the system causing the members to respond due to their kinematic and dynamic characteristics and thereby creating relative motion between the members. The trigger member is coupled to the at least the first member and moves in response to a pre-determined system movement. When the trigger member moves, the trigger member imposes a braking action on the system or a member or members thereof. The speed and/or intensity of the braking action imposed by the trigger member on the system or a member or members thereof is controlled by the trigger member rate of movement. This rate of movement is in turn governed by a magnetic flux interaction between the trigger member and the at least one first member causing formation of a magnetically induced eddy current force between the parts.

A safety brake for an elevator system including a car and a guide rail is provided. The safety brake is adapted to limit movement of the car in a first direction (D.sub.1) along the guide rail when in a braking state and comprises: first and second braking members adapted to be wedged against the guide rail when in a braking state; and an electromagnetic actuator, wherein the safety brake is configured such that: the first and second braking members are biased towards one another in a second direction (D.sub.2) substantially perpendicular to the first direction (D.sub.1); the first and second braking members are held in a non-braking state spaced apart from one another and the guide rail when the electromagnetic actuator is in a first state; and when the electromagnetic actuator is in a second state, the first and second braking members are moved into the braking state.

Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.

According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

An actuator includes a control part, a first rotation sensor, and a second rotation sensor able to detect rotation of an output shaft. The control part performs a first rotation angle acquisition control for acquiring a target rotation angle of the output shaft when a movable part is moved from the second position to the first position as a first rotation angle. The first rotation angle is a rotation angle of the output shaft that is closer to the second position side than when the movable part abuts the first wall part. In the first rotation angle acquisition control, the control part causes the movable part abuts the first wall part, acquires a rotation angle of the output shaft when the movable part has abutted the first wall part, and calculates the first rotation angle based on the rotation angle of the output shaft that has been acquired.
