Title: Brian Verstegen - Innovator in Keyboard Technology
Introduction
Brian Verstegen is a notable inventor based in Sunnyvale, CA. He has made significant contributions to the field of keyboard technology, holding a total of 2 patents. His innovative designs focus on enhancing the efficiency and functionality of personal computer keyboards.
Latest Patents
One of Brian's latest patents is the "Interrupt-generating keyboard scanner using an image RAM." This system assists in scanning keyboards associated with personal computers. It features a logic circuit that interacts with the microcontroller and the keyboard to reduce power consumption while allowing the microcontroller to perform other tasks. The logic circuit generates an interrupt whenever keyboard activity is detected, and an image RAM stores a pattern of current key closures for comparison in subsequent scans. This innovation allows for efficient power management by stopping scanning when no keys are pressed.
Another significant patent is the "Sleep mode refresh apparatus." This circuit is designed to wake a microprocessor from sleep mode and provide it with a clock signal long enough for refresh, direct memory access (DMA), or master cycle operations. After the necessary operations, the clock signal is removed to conserve energy, and a hold signal is provided to put the microprocessor outputs into a tri-state, high impedance condition. This design relinquishes control of the external bus to the refreshing circuitry, further enhancing energy efficiency.
