Latest Patents

One of his latest patents is a wireless power transfer system that utilizes inductive power transfer across a rotary joint. This system includes a first portion with a magnetically permeable power transmit core and a power transmit coil, along with a second portion comprising a magnetically permeable power receive core with a power receive coil. The core material directs a time-varying electromagnetic field emitted by the power transmit coil toward the power receive coil, allowing adjacent devices to operate without interference. For instance, a brushless direct current motor can function while power is being transferred, and data can be wirelessly transmitted between the two portions.

Another notable patent is a rapid braking system for an autonomous mobile device. This device employs a motor that can quickly and safely stop to avoid collisions or respond to internal failures. Upon receiving a stop signal, the motor disconnects from the battery, and a braking circuit is activated to dissipate power produced by the motor's motion. Once the voltage drops below a certain threshold, a stop circuit shorts the motor's terminals, preventing further rotation. When the stop condition is lifted, normal operation resumes seamlessly.
