Latest Patents

One of Hesselbom's latest patents involves a network comprising converters between electrical and optical signals. This network is designed for use in environments such as apartment buildings, where it facilitates a partly optical transmission of information between subscribers and a centrally arranged switch. The connector housings in this network feature an electrical connector at one end and a connection terminal for an optical fiber at the opposite end. An electronic converter is integrated to convert between electric and optical signals, ensuring that the optical transmission operates as an electric signal line from the switch's perspective.

Another significant patent pertains to a transmission line of strip type, which includes a dielectric with a local dielectric constant that alternates between at least two different values. This transmission line can be manufactured by applying a first layer of material with a specific dielectric constant to a base, followed by patterning the first layer to create recesses. A second layer of material is then applied to fill these recesses, resulting in a flat surface. This design is not only cost-effective but also space-saving, making it suitable for various types of filters and delay lines.
