Abstract: To reduce sound emission and at the same time improve stability, a multilayer board for acoustic insulation is proposed that includes, but is not limited to a core sheet arranged between a first and a second covering layer. At least one of the two covering layers is of a closed design. The core sheet is firmly connected in a planar fashion to the covering layers. The core sheet comprises slits that extend within the core sheet in the direction of the core sheet thickness, which slits reduce the shear stiffness of the board and thus ensure an improved acoustic insulation effect. On both sides the core sheet comprises continuous edge zones, which extend parallel to the covering layers. An aircraft can have an interior lining formed by panels that comprise the multilayer boards in order to provide acoustic insulation.

Abstract: An animal leash such as, for example, for dogs, may include an elongated flexible sleeve having a proximal end and a distal end. The proximal end of the sleeve is configured to be held by a hand of a user and includes an opening for accessing an interior pocket of the sleeve. A rigid rod may be removably received within the interior pocket of the flexible sleeve through the opening to optionally make the animal leash rigid for training and/or controlling an animal (e.g., a dog) releasably attached to the leash. An attachment portion may be coupled at or near the distal end of the sleeve and may be configured to be releasably attached to a collar or harness on the animal.

At least four compartments are interspaced between four corner compartments to store tackle.

Abstract: A system for increasing the thrust and power capabilities of a side-by-side vertical takeoff and landing vehicle to optimize the coaxial rotor performance. The system includes a first coaxial rotor spaced from an aircraft body and a second coaxial rotor spaced from the aircraft body and opposite the first coaxial rotor. The first coaxial rotor has a first top propeller aligned with a first bottom propeller along a first rotational axis. The second coaxial rotor having a second top propeller aligned with a second bottom propeller along a second rotational axis. A gyroscopic moment to maintain pitch stability is controlled by modulating the first and second top propellers, which have a different angular speed or different torque from the first and second bottom propellers, and tilting the first and second coaxial rotors towards the central axis with a common tilt angle and a common tilt rate.

Abstract: A de-icing device for an aircraft nacelle includes two electric bands, and each of them is made from one main conductor oriented along a length of the band. In particular, the two electric bands have rectilinear elements and bent elements and are located on a same plane. Moreover, the two electric bands include spirals formed by association of several bent elements. Contiguous bands are embedded together in pairs, and the embedded bands are powered by different power supplies.

Abstract: A plurality of pliant scrapers are preferably secured to a feeder grille. The grille keeps an animal from walking in the feed. The scrapers are pliant to flex when the animal presses its head into a gap between adjacent scrapers, without causing undue pain or harm. When the animal pushes into the gap between adjacent scrapers, the pliant scrapers spread sufficiently to allow the animal's head to pass. When the animal subsequently backs out of the feeder, the pliant scrapers flip from pointing into the gap to pointing slightly out from the gap. As the animal continues to recede from the feeder, the scrapers wipe across the face and mouth of the animal. The wiping separates any unsecured hay or feed from the mouth of the animal. When the scrapers eventually separate from the animal, they spring towards the feeder interior, thereby propelling loose hay back into the feeder.

The trigger finger hooks into the pop-up indicator. Rotation of the fishing line reel by a fish strike causes the trigger finger to release the pop-up indicator. A light emitting strike indicator may be used for night time fishing.

Abstract: Embodiments of a flight-control system and methods of reducing the probability of a roll-control reversal in a canard-controlled flight vehicle are generally described herein. In some embodiments, the flight-control system may monitor angular velocities of the flight vehicle to detect the onset of instability and adaptively control an acceleration limit of the flight vehicle based on the detected instability to reduce the probability of a roll-control reversal. The onset of instability may be detected by persistently high angular velocities. The acceleration limit may be further adaptively controlled based on an approach of a vehicle trim limit.

A plurality of spaced apart floor ducts are connected to the vertical side ducts.

Abstract: A spacecraft deployment mechanism employing a pair of bi-stable tape springs attached to a cylinder such that rotation of the cylinder extends or retracts the tape springs in opposite directions. The tape springs are fabricated such that they are stable when wrapped around a cylinder (stowed configuration) or when deployed and have a higher energy state when stowed than when deployed. A plurality of bi-stable tape spring mechanisms may be combined to create a deployment device that does not impart rotational torques to the spacecraft during deployment. Deployment may be accomplished by release of the stored energy in the coiled or packaged state progressing to the lower energy deployed state. Alternatively, a motor may be employed to rotate the cylinders for deploy or retrace the tape springs.
