Latest Patents

Among John’s notable patents, two standout innovations include:

1. **Aircraft Icing Sensors**

This inventive icing sensor employs a surface gap transmission line, through which a radio frequency is transmitted. The phase delay of this frequency is influenced by the dielectric constant at the surface within the gap between the transmission line electrodes. By monitoring changes in the dielectric constant, the sensor can detect various forms of precipitation, including ice, water, and snow, as well as fluids that depress freezing points, such as ethylene glycol. When integrated into an aircraft’s control surface, the sensor predicts the presence of icing conditions and the onset of ice accumulation. This technology aims to enhance safety by minimizing the cost and effort associated with aircraft de-icing processes.

2. **System and Method for Receiving and Decoding Global Positioning**

This patent describes a system designed to receive and demodulate spread spectrum positional signals, such as those generated by GPS satellites. By frequency shifting these signals to baseband and applying digital signal processing techniques, the system can effectively derive pseudo-range, carrier phase, and Doppler frequency. The design allows for processing to be implemented by standard audio digital signal processors, making the technology both efficient and accessible.
