Latest Patents

One of his latest patents is titled "Nine-axis quaternion sensor fusion using modified Kalman filter." This system is designed to determine and correct the calculated orientation of a computing device by utilizing data from an accelerometer and a gyroscope. The innovative aspect of this system lies in its use of a modified Kalman filter that updates covariance to reduce decay over time based on a residual of the filter. Additionally, gyroscope bias is tracked and offset based on the updated covariance and the residual, which is derived from an observational orientation determined by the angle between a measured acceleration vector and an expected acceleration vector.

Another notable patent is the "Field of view extender for camera." This invention includes prisms that direct light from angles outside the camera's lens view onto the image sensor. By doing so, it piecewise extends the field of view beyond the unaltered angle of view. The prisms are strategically oriented to direct light around the outer region of the image sensor, which can generate signals for motion detection purposes. Each prism is spaced apart from adjacent prisms, creating an alternating sequence of prisms and gaps, while the inner region of the image sensor captures imagery suitable for user output.
