Title: The Innovations of Norman C. Seiler

Introduction

Norman C. Seiler is a notable inventor based in West Melbourne, FL (US). He has made significant contributions to the field of technology, holding a total of 7 patents. His work primarily focuses on advanced coding schemes and digital-to-analog conversion technologies.

Latest Patents

One of Seiler's latest patents is a speech data encoding scheme. This innovative coding scheme utilizes Shannon-Fano coding for data headers to identify the type of command signal. It employs a first set of formant data in the command signal to generate second sets of formant data for sound class initialization. Additionally, it uses delta modulation to update the initialized sound class and manage sound type transitions. The header of this scheme indicates whether it is initializing sound classes, repeating the previous command, updating the previous command, or signaling the end of a word. The command signals and sound classes share the same header, while the data portion of the command signal defines the specific type of command signal present. A unique delta modulation scheme is implemented, where an increment, decrement, or no change is indicated by specific binary codes.

Another significant patent is the Gray code DAC ladder. This invention features a Gray code digital-to-analog converter with both inherently monotonic and not inherently monotonic embodiments. The inherently monotonic embodiment connects a first end terminal of a ladder stage to the intermediate terminal of a previous stage, while switching the second end terminal between the end terminal of the previous stage. In contrast, the not inherently monotonic embodiment utilizes an R-2R ladder, where the end terminals of the stage are switched by a double pole, single throw switch between an end terminal and an intermediate terminal of the previous stage.
