Latest Patents

One of Walker's notable recent patents is the **Stepper Motor Controller**. This invention introduces a stepper motor control circuit that minimizes ripple current by employing both fast and slow current decay methods during the motor's phase when reducing current. It starts with a swift decay to lower winding current, followed by a transition to a slower decay until the winding current is sampled again. The control circuitry monitors the winding current, comparing it with a reference current to assess whether to apply or reduce the current using either decay method. Additionally, it features different phase current sample circuits that enable constant or selective current sensing, showcasing an advanced solution in motor control technology.

Another significant patent is the **Sample Container Segment Assembly**, designed for an automated, continuous, random access analytical system. This assembly includes a unique sample container that is received by a segment designed to fit onto a carousel of the analytical instrument. The container features an upper skirt and a reservoir for storing the test sample. Complementing the design, the segment incorporates a base, frame, and handle, with the frame providing a shelf and openings for securing the sample container's body. Enhanced by alignment pins and a carousel trough, this assembly improves the efficiency of sample handling in analytical processes.
