Title: Brian L Abernethy: Innovator in Digital Technology
Introduction
Brian L Abernethy is a notable inventor based in Phoenix, AZ, who has made significant contributions to the field of digital technology. With a total of three patents to his name, Abernethy has focused on innovations that enhance the functionality and efficiency of digital devices.
Latest Patents
Among his latest patents is the "Cordless digitizer transducer/cursor status transmission apparatus." This invention features a cordless transducer that includes a transmitter designed to work with the receiver of a digitizer tablet. The transmitter captures parallel binary signals that represent the status of non-positional functions, such as command button status and pressure applied to the stylus. It then converts these signals into a serial stream of binary data for transmission to the receiver, which subsequently converts the data back into parallel binary signals.
Another significant patent is the "Voltage controlled oscillator circuit employing integrated circuit." This integrated voltage-controlled oscillator (VCO) circuit utilizes the relative capacitance and resistance ratios within an integrated circuit to produce a signal with a predictable frequency based on a control signal voltage. The design ensures that the output frequency remains consistent across different IC chips, with a variance of no more than 3.0%. This reliability is achieved through the inherent stability of the capacitance and resistance ratios in the IC.
