Abstract: A flap support mechanism includes a track rotatably connected to an aft fitting of a wing. A forward roller and an aft roller extend laterally from a flap structure, the forward roller and aft roller constrained in a slot in the track. The slot has a profile configured to induce both translation and rotation in the flap, in concert with rotation of the track about the aft fitting, thereby passively mirroring motion of the flap induced by an actuator driven primary main flap support.

Abstract: A plinth attachment system for attachment to at least one track includes: a first plate having a first side configured for mounting to a longitudinally extending track, and a first mounting feature for mounting a first structure; and a second plate having a first side configured for mounting to the track, and a second mounting feature for mounting a second structure. When mounted on the track, at least one interlinking feature of the first side of the first plate and at least one interlinking feature of the first side of the second plate interlock at the track, and, the first mounting feature and second mounting feature are aligned at essentially equivalent longitudinal positions.

Abstract: A hybrid support rail for receiving fixtures in a cabin of a vehicle includes a support rail base, first attachment elements, second attachment elements formed so as to be complementary to the first attachment elements, and a support rail upper part. The support rail base has a lower side and an upper side. The upper side has a receiving housing extending along a main extension direction of the support rail base for sliding in first attachment elements and, on a side facing away from the lower side, a support surface having at least one recess. The receiving housing is formed so as to prevent the first attachment elements from sliding out towards the support surface. The support rail upper part has a contact surface for placement on the support surface. The contact surface has recesses through which the second attachment elements are guided for insertion in the first attachment elements.

Fail-safe electrical drive unit may include input shafts, fixedly attached belt pulleys that are fixedly attached to the respective input shafts, output shaft that is coupled to rotor, freewheeling belt pulleys that are mounted to output shaft by means of respective freewheels such that output shaft rotates freely when output shaft rotates faster than one of the freewheeling belt pulleys belts that connect fixedly attached belt pulleys with the respective freewheeling belt pulleys, and electric motors that are coupled with the respective input shafts.

Abstract: A floor fixing assembly for releasable fixing of a leg of a frame to a vehicle floor comprises at least one retaining peg which can be fixed to the vehicle floor. The floor fixing assembly furthermore comprises a frame fixing element, which is configured to be connected to the leg of the frame and comprises at least one receiving space for receiving the retaining peg. A clamping device is configured to be introduced into the receiving space of the frame fixing element in order to connect the frame fixing element to the retaining peg by form fit.

Abstract: The present invention features an elegantly-mounted pinwheel comprising alternating holographic red and silver non-metallic tape-like material. The pinwheel uses connector bolts and hexagonal coupling nuts to be mounted or positioned directly onto various components of a power pole or utility pole system such as bushings, fuse cutouts, regulators, reclosures, lightning arresters, or underground primary dips. The invention will deter animals such as birds and squirrels from scaling or landing on the power pole or utility pole system when the invention is properly mounted. The invention takes advantage of the alternating colors of the pinwheel to scare the animals. The present invention requires no housing, rotors, drums, or support plates. The invention does not rely on sound, and it requires no electricity or motor. The stainless steel hex standoff coupling nut comes preferably in ?? and can be ordered in different sizes to accommodate the device.

Abstract: A package delivery apparatus of a vehicle may include a servo, a servo arm rotated by the servo, a latch that rotates responsive to rotation of the servo arm, and a rod and slider that moves responsive to rotation of the servo arm. The components of the package delivery apparatus may move between a plurality of positions, including a loading position, a locking position, a sensing position, and a release position. The rotation of the latch may control loading, locking, sensing, and release of a package within a package path of the vehicle, and the movement of the rod and slider may control movement of a door assembly of the vehicle between open and closed positions.
