Emergency actuating device
Emergency actuating device, especially for vehicle doors, is provided. The device includes: a support base; a manual actuation element adapted to assume rest and actuation configurations; an electromagnetically driven locking mechanism adapted to lock the actuation element in its rest configuration; a protective shell adapted to assume a closed configuration in which the shell isolates the actuation element from the outer environment when the actuation element is in its rest configuration, and makes it impossible to reach the actuation element with a hand, and an open configuration, in which the actuation element can be reached with a hand to be brought from the rest configuration to the actuation configuration and vice versa; and an opening sensor adapted to generate an electric signal indicative of the open configuration of the protective shell, the signal being processable by an electronic control unit for controlling locking and/or unlocking of the locking mechanism. |

Modular surface mounted electric strike
A modular surface mounted electric strike system is provided. The system comprises a universal base plate having first and second sides, each having first and second mounting points. Each electric strike module includes a header, a keeper assembly, and an actuator assembly configured for moving between a keeper blocking mode and a second mode. When the first and second latches are separated a first distance, the first and second electric strike modules are attached to the first mounting locations on the respective first and second sides of the base plate. When the first and second latches are separated a second distance, the first electric strike module is attached to the second mounting location on either the first or second sides of the base plate, and the second electric strike module is attached to the second mounting location on the other of the first or second side of the base plate. |

Keycam assembly
A keycam assembly including a rotatable member, a stem, a locking member coupled to the stem for joint longitudinal movement therewith, and a cam driver. The rotatable member includes an aperture. A proximal end portion of the stem is rotatably seated in the rotatable member and defines a cam track. The locking member extends between the aperture and the cam track. The cam track includes a first passage including a locking pocket, a second passage including an unlocking pocket, a first ramped passage including a locking ramp extending from the second passage to the locking pocket, and a second ramped passage including an unlocking ramp extending from the first passage to the unlocking pocket. Relative rotation of the rotatable member and the stem causes the cam driver to travel along the track to thereby cause movement of the locking member between a locking position and an unlocking position. |

Collars for use in either driving posts into or removing posts from the ground, and related methods
A collar is provided that can be used to either drive posts into the ground or remove posts from the ground. The collar includes a first portion defining a post opening adapted for coupling about a post, and a second portion coupled to the first portion. The second portion includes a receiver adapted for receiving a tool for use in driving the post into the ground when the first portion is coupled about the post. The first portion defines an obtuse angle with respect to the second portion. The collar is configured to be positioned in a first orientation about a post when used to drive the post into the ground, and a second orientation, rotated approximately 180 degrees relative to the first orientation, when used to remove a post from the ground. |

Drywall repair apparatus and method
A drywall repair apparatus and method. The apparatus includes a plastic puck that is dimensioned to fill a hole in damaged drywall. The apparatus is anchored inside the wall. The apparatus may have an integrated plastic puck mounted on a plastic plank. The device mounts inside the wall and the puck fills the ½″ deep void, leaving only 1/16″ to be filled with joint compound. There is no time-consuming multiple layering required. There is no need for broad feathering to hide the repair and the repair is as solid as the original wall before damage. |
