Abstract: The present specification discloses an anchored hole cover for a bore hole cored from a paved surface that includes a cover plate configured to cover the bore hole and support vehicular traffic. An anchoring mechanism is attached to the cover plate and extends down into the bore hole. The anchoring mechanism is configured to be actuated by a user torque input that is transmitted through a linkage system to cause an anchoring mechanism to selectively engage or disengage the wall of the bore hole. When the anchoring mechanism is engaged with the wall, the anchored hole cover is prevented from being unintentionally extracted from the hole. The anchored hole cover effectively provides a temporary cover for a bore hole in a road, parking lot, or other paved surfaces that supports vehicular traffic, that prevents extraction due to vibrations of passing traffic, thus preventing damage to cars and their occupants.

Abstract: A waste-less cut-less composed wooden panel for a wooden timber buildings construction. Thanks to the use of the steel wood screws positioned in a pattern, the same buckling resistance as in the case of the commercial wooden panels connected by aluminium nails or wood screws has been achieved with a much lower value of the wooden panel thickness, approximately by 30%. Thanks to the manual assembly of individual waste-less cut-less composed wooden panel, up to 82% of wooden material can be saved compared to commercially available prefabricated wooden panels.

Abstract: A self-resetting tuned mass damper is based on eddy current and shape memory alloy technology. The self-resetting tuned mass damper comprises a hollow box, a cover plate, a bolt, a mass block, gears a, gears b, gears c, copper sheets, permanent magnet groups, partition boards, balls, pins, levers, shape memory alloys, rotating shafts a, rotating shafts b, a supporting plate and rotating shafts c. The movement of the mass block causes the copper sheets to rotate and generate eddy current for energy consumption. The copper sheets are rotated and amplified by adjusting the sizes of the gears. The displacement of a small mass block can cause rotation of the copper sheets by a large angle, which greatly increases energy consumption efficiency. The elongation of the shape memory alloys is amplified by adjusting the ratio of long and short force arms of the levers.

Abstract: A floating body device for suppressing vibration of enclosure includes a floating body surrounding the enclosure and an excitation device which can excite the floating body to float up and down. The excitation device includes a tether connected to the floating body to prevent the floating body from falling off from the enclosure. When the floating body floats up and down, an airflow boundary layer on an outer wall of a tower can be destroyed, and a cause of vortex-induced vibration can be directly suppressed. In addition, a change of an aerodynamic configuration is obtained. The up and down floating of the floating body disrupts both upper and lower sections of a nearby flow field, thus weakening a combined action thereof, thereby preventing the vortex induced vibration of the tower.

Abstract: Several pre-assemblies holding panels of photovoltaic cells are constructed and pre-wired in a factory. The pre-assemblies are shipped to a solar farm, where they are lifted above posts secured to the ground using, for example, using an excavator connected to an end effector. The pre-assemblies are then connected to the posts and electrically coupled to one another. Such installation of solar panels in a solar farm may be faster and less labor-intensive than other types of installation.
