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 lithium-iron-phosphate battery backup system for use with an electric actuator. The battery backup system includes a controller for detecting a power failure and supplying backup power to the actuator to close a valve or damper connected to the actuator. The system can also detect out of range environmental conditions, and defects to the battery backup system. The battery backup system also includes a system for boosting the current and voltage of the batteries in the system.

A system includes multiple controllers that provide operation of a closure with multi-layer functionality and redundancy. One controller monitors a state of a latch coupled with the closure, while another controller controls a motor used to actuate the latch. When the controller monitoring the state of the latch detects a fault, the controller communicates the fault to the other controller and the other controller disables the motor, thus preventing further movement of the latch, and in turn, the closure.

The invention discloses a power supply fault protection circuit of a NOR memory, which relates to the technical field of NOR memorizers, and comprises a first voltage stabilizing module matched with a second voltage stabilizing module to supply power to a mainboard module, then the mainboard module supplies power to a memory module, and a voltage detection module detects the voltage change of the memory module. The power supply control module can set a first voltage threshold or a second voltage threshold according to the working voltage required by the memory module, and when the first voltage threshold is used as a voltage comparison value of the voltage detection module and the voltage changes, the auxiliary power supply module controls the first voltage stabilization module to perform current expansion and supply power to the memory module. And the memory module stops receiving the electric energy provided by the mainboard module, and similarly, when the second voltage threshold value serves as a voltage comparison value and the voltage changes, the second voltage stabilizer module is controlled to expand the current and supply power to the memory module. The power supply fault protection circuit of the NOR memory can improve the power supply safety and the working efficiency of the memory module.

Systems and methods improve the actionability of leaks in cable networks. One or more leakage detection confidences (LDCs) are determined to assess the reliability of newer leakage data which conflicts with existing leak records. When confidences fail to exceed predetermined thresholds, records of leaks which failed to be redetected are maintained as actionable and relied upon for the creation of work orders and deployment of technicians to make repairs. Further fail safe conditions may include device health metrics and weather events.

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.

According to embodiments of the present disclosure, a motion based fails safe braking for trolleys is disclosed herein. The trolley includes a brake system that allows for safe operation of the trolley on ramps. The trolley may include various mechanical elements that act as force and displacement multipliers connected to a fixed wheel with a Deadman's brake. The wheel is connected to a hitch point of the trolley. During normal operation, the vehicle that drags the trolley exerts a pull force at the hitch point which releases the brakes, in turn causing the trolley to move. When the tugging operation has ceased, there is no pull force. This releases the brake lever and engages the brake. On gradients and ramps, this braking system ensures there is minimal or no trolley motion.

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.
