Introduction

John Ryan Clark is a notable inventor based in Howell, Michigan, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in MEMS (Micro-Electro-Mechanical Systems) technology, which has significant implications for frequency and timing generation.

Latest Patents

One of his latest patents is for a compound spring MEMS resonator designed for frequency and timing generation. This innovative resonator body is constructed using one or more spring unit cells that form a compound spring block. Each compound spring block is anchored at nodal points to ensure a high quality factor. The design includes masses attached to the open ends of the compound spring block, which are capacitively coupled to drive and sense electrodes. The dimensions of the spring unit cells, the number of spring unit cells for a compound spring block, and the size and weight of the masses are meticulously selected to achieve a desired resonant frequency. Additionally, the number of compound spring blocks is chosen to tune the electrical characteristics, such as impedance, of the MEMS resonator.

Another significant patent is the multiple coil spring MEMS resonator. This resonator features a center anchor and a resonator body that includes two or more coil springs extending in a spiral pattern from the center anchor to an outer closed ring. Each pair of coil springs originates from opposing points on the center anchor and extends in a spiral pattern to opposing points on the outer ring. The design parameters, including the number of coil springs, their length and width, and the weight of the outer ring, are selected to realize a desired resonant frequency.
