With a total of five patents to his name, Halonen's work focuses on enhancing the efficiency and effectiveness of hardware implementations.
Latest Patents
One of Halonen's latest patents is a "Multiplier and shift device using signed digit representation." This invention proposes a multiplier device that performs multiplication of different powers of two serially in time, rather than in parallel. This approach reduces the area needed for hardware realization by enabling the use of only one adder in connection with the multiplication. Additionally, a shifter means based on binary weighted shifting is utilized, further minimizing the required hardware amount and area for implementation. This invention is applicable in various digital multiplication scenarios, including digital signal processing, digital filters, and adaptive digital filters.
Another significant patent is the "Method for correcting errors in parallel A/D conversion, corrector and parallel A/D converter." This invention addresses the correction of errors in parallel analog-to-digital conversion caused by uncertainties in reading the states of parallel comparing elements. By employing a nonlinear cellular neural network, the invention estimates the real level of the phenomenon compared, thereby correcting the errors associated with non-simultaneous state latching.
