Latest Patents

One of his latest patents is titled "Mechanical vibration system and control method with limited displacement." This invention focuses on a control method that independently modifies the higher and lower frequency components of a drive signal. The goal is to satisfy a target profile while limiting displacement in the driven vibration. The method involves adjusting the phases of the lower frequency components in a preliminary drive spectrum to ensure that peaks are non-simultaneous and distributed in time, thereby avoiding constructive interference. Additionally, the lower frequency components can be applied as a filter to narrow-band time waveforms, such as those with swept frequencies, to obtain the desired lower-frequency time waveform.

Another significant patent by Snyder is the "System and method for generation and control of mechanical vibration." This invention independently controls both the frequency spectrum and amplitude distribution of a vibration generation system. It utilizes sensed vibration in feedback to generate a controlled drive signal applied to a mechanical actuator. The amplitude distribution is adjusted to match a specified statistical characteristic, such as kurtosis, by modifying the relative proportion of a coherent component in a randomized phase. This is then combined on a frequency-by-frequency basis with the separately adjusted frequency spectrum.
