Title: Innovations of Henri Girard
Introduction
Henri Girard is a notable inventor based in Carmel, IN (US). He has made significant contributions to the field of technology, holding a total of 7 patents. His work primarily focuses on advancements in communication technology and electronic devices.
Latest Patents
Among his latest innovations is a surge protector for a transceiver. This invention addresses the vulnerability of an input N-plexer filter stage to surge energy. The design incorporates a high-pass filter in a diplexer filter stage that applies a radio frequency (RF) signal between the input N-plexer filter stage and the output of a Data Over Cable Service Interface Specification (DOCSIS) transmitter stage. Additionally, a low-pass filter in the diplexer filter stage couples a surge suppressing threshold device to the signal path, effectively dissipating surge energy when it occurs. The low-pass filter is designed with a cut-off frequency lower than the normal operational frequency range of the RF signal, ensuring isolation of the surge suppressing threshold device during normal operations.
Another significant patent is an antenna structure with dielectric loading. This invention features a first set of conductive elements forming a portion of the antenna structure on a first layer of a multi-layer printed circuit board. A second set of conductive elements is formed in parallel on a second layer of the same board. This innovative design enhances the performance and efficiency of the antenna structure.
