Latest Patents

Heine's latest patents include a **Mechanical Attenuator** and a **Hysteretic Energy Absorber**. The **Mechanical Attenuator** is a sophisticated system intended to prevent horizontal forces from being transmitted from a base, such as the ground, to a structure like a building or a nuclear reactor. The system comprises two main components: a vertical support, which allows for free relative horizontal movement between the structure and the base, in addition to horizontal damping. These components can function together or separately, with the support potentially being provided by materials such as rubber, rolling bearings, flexible columns, or tendons.

The **Hysteretic Energy Absorber** serves as a cyclic absorber of energy, capable of managing massive quantities. This device is especially effective when installed between two parts of a structure that are liable to move relative to one another due to forces such as earthquakes or strong winds. The energy is absorbed through the cyclic, flexural deformation into the plastic range of a primary beam, which can be configured as a single or double cantilever. The device's efficacy can be enhanced by using short auxiliary cantilevers that initially contact the main beam, allowing for the distribution of strain and increasing the overall capacity.
