Latest Patents

One of Bruno Biffi's latest patents is a piezo-resistive force sensor with bumps on a membrane structure. This force sensor is designed to measure the force from a load and includes a plunger, a flexible disc-shaped membrane, a support plate, and a silicon die. The plunger receives the force from the load and features a ring-shaped groove at its lower surface. The membrane is equipped with a ring-shaped upper bump that fits into the groove of the plunger, while the support plate has a complementary groove for the lower bump on the membrane. The silicon die, mounted centrally on the membrane, contains piezo-resistors that change resistance when deformed by the applied force. This innovative design allows for accurate force measurement through the flexing of the membrane and the compression of the silicon die.

Another significant patent by Biffi is a method and system for coding moving image signals, along with a corresponding computer program product. This invention involves coding a moving-image signal, such as a luminance signal organized in blocks of pixels. The process includes comparing a block to be coded with multiple candidate prediction blocks, determining an index value representing the difference between the blocks, and selecting a prediction block based on this index. The signal is sampled pixel by pixel, generating surfaces that represent the signal patterns in both the block to be coded and the candidate prediction blocks. The chosen index reflects the parallelism between these surfaces, enhancing the efficiency of image coding.
