With a total of five patents to his name, Holmbo has demonstrated a commitment to innovation and advancement in his field.

Latest Patents

One of Holmbo's latest patents is a television signal generator. This fully digital device utilizes digital data stored in Programmable Read-Only Memories (PROMs), with one PROM dedicated to each component of the desired encoded television signal. The system clock enables a signal address generator to fetch data from the PROMs. The chrominance data is mixed with appropriate digital representations of a sinusoidal function and a phase offset, which is then added to the luminance data. The combined digital signal is converted to analog, filtered, and output as the desired encoded television signal.

Another significant patent is a method of detecting and characterizing anomalies in a propagative medium. This method is designed for examining mediums such as signal transmission cables. It requires the acquisition and examination of a minimal number of data points to identify the presence of an anomaly. Once detected, the characteristics of the anomaly, including its location, type, and amount of loss, are determined and displayed. If the anomaly is a reflectionless loss, the region is examined repetitively to improve the accuracy of its location measurement. This innovative approach allows for the collection of additional samples to reduce random noise in the data, leading to a more precise determination of the anomaly's location.
