Latest Patents

O’Neill is credited with 1 patent: “System and Method for Deconvolution of Real-Time Mass from the Influence of Temperature and Pressure on Crystal Microbalance.” The invention describes a system for identifying changes in a crystal microbalance sensor’s resonance frequency that arise from temperature, then separating those effects from changes used to determine incremental mass.

The method uses dual-mode resonances and associated coefficients to estimate and remove temperature-related frequency shifts. One embodiment combines a mass mode, such as the c-mode fundamental frequency, with a temperature mode, such as the anharmonic frequency. Other embodiments use the b-mode fundamental frequency as the temperature mode to improve sensitivity to temperature changes. The resulting calculation provides a temperature-compensated estimate of incremental mass.
