Latest Patents
Van Patten's latest patents illustrate his creative approach to engineering:
1. **Digital Current Regulator**
This invention involves a digital current regulator designed for controlling inductive devices, such as AC motors. The regulator employs a multitude of independently controllable insulated gate bipolar transistors, which are selectively enabled to adjust the instantaneous phase and magnitude of the current delivered to the AC motor. To enhance reliability, Van Patten has incorporated several safeguards to mitigate induced back EMFs during switching operations. The system is designed to switch between adjacent states only to minimize sudden current fluctuations. Additionally, features like a 'ready blocking' function and a 'time out' function are integrated to ensure smooth operation, maintaining the system's efficiency while preventing derating of switching device capabilities. A time hysteresis function further protects against false feedback control signals.
2. **Linear Resolver Utilizing Plural Nulled Coil Sets**
This patent introduces a linear resolver that utilizes multiple pairs of nulled coil sets arranged in a co-linear fashion to precisely sense the position of magnetically permeable objects. The excitation coil generates an alternating magnetic field, which interacts with the nulled coil sets across a magnetic gap. As an object enters the gap, the coupling increases, prompting varying outputs from each coil set. The design cleverly offsets the outputs of individual pairs by a quarter cycle, allowing for accurate detection of multiple edges of the object. Each pair's data can be processed separately, enhancing the capabilities of edge detection.
