The invention relates to an actuator assembly (200, 300, 600, 700) for connection to an apparatus (101) comprising a body and a central passageway (202, 302, 602, 702) extending along a longitudinal axis of the body, wherein the actuator assembly comprises: - a sliding stem (207, 307, 607, 707), - an obstructing member (201, 301, 601, 701), fixedly attached to the sliding stem (207, 307, 607), - a first compartment (403, 403', 603, 703, 703'), a second compartment (404, 404', 604, 704, 704') and a third compartment (513, 513', 611, 711) having varying volumes depending on the position of the sliding stem (207, 307, 607, 707), wherein the volume of the first compartment (403, 403', 603, 703, 703') increases and the volume of the second compartment (404, 404', 604, 704, 704') decreases when the sliding stem (207, 307, 607, 707) slides in one direction, and the volume of the first compartment (403, 403', 603, 703, 703') decreases and the volume of the second compartment (404, 404', 604, 704, 704') increases when the sliding stem (207, 307, 607, 707) slides in another opposite direction.

A mount to connect a fan cowl support beam to an engine fan case of an aircraft. The mount has a primary load path component and a secondary load path component. The primary load path component is configured to fuse upon application of a force from the fan case that is above a predetermined threshold. The secondary load path component is configured to remain functional upon application of the force above the predetermined threshold to maintain the fan cowl support beam connected to the fan case.

A technique including capturing, by one or more cameras of a set of cameras disposed about a vehicle, one or more images, wherein a surround view system of the vehicle is configured to render a surround view image using a first hardware accelerator based on the one or more images, determining that a first hardware accelerator is unavailable, and rendering the surround view image using a second hardware accelerator based on the captured one or more images.

Example implementations include a method, apparatus and computer-readable medium for intelligent power fail-safe of a network video surveillance camera, comprising detecting a loss in external power from an external power supply to the network video surveillance camera. The implementations further include powering the network video surveillance camera with an internal power supply in response to detecting the loss in external power from the external power supply.

A winch has a cable reel, a winch body capturing the cable reel, and an indexing lock. Two separately actuated pawls provide a first level of fail-safe protection. A drive coupler enables rapid torque wrench cable tension adjustment. Locking pin holes on the cable reel and winch body are arranged so a locking member can pass through only one visible winch body locking pin hole, with the other visible holes at least partially blocked, independent of pawl position. The locking pin provides a second level fail safe. As the cable reel is rotated by the drive coupler, even by a small amount less than required for a single pawl ratchet tooth displacement, another visible winch body locking pin hole will align and open. As a result, very precise cable tension and reel position can be preserved by insertion of the locking pin into the only open locking pin hole.
