Latest Patents
Ari Seppälä's latest patents include a cold-crystallizing material and a method for utilizing cold-crystallization in heat storing. This invention relates to a cold-crystallizing material that possesses high latent heat, along with a method for using this material for effective heat storage. The material comprises a phase change material and an additive, which is preferably a hydrophilic polymer matrix. Sugar alcohols, such as erythritol or D-mannitol, are utilized as the phase change material. The polymer is designed to be cross-linked and ionic, specifically a polyelectrolyte. This phase change material is capable of storing a significant amount of heat energy while melting and releasing the stored thermal energy through cold-crystallization. Compared to previously studied materials, the latent heat of Seppälä's cold-crystallizing material is considerably higher, and the cold-crystallization process is more repeatable across successive melting-crystallization cycles. This innovative material can be employed for long-term heat storage, with the ability to release heat energy on demand through a heat pulse.
Another notable patent is a method and device for simulating a radio channel. This invention involves a method and device that includes a set of channel simulation units designed to simulate a radio channel. Each unit consists of radio frequency parts and baseband parts. In this solution, the baseband parts of several different units are arranged to simulate the same channel, enhancing the efficiency and accuracy of radio channel simulations.
