Quaternionic attitude estimation for robotic and human motion tracking using sequential Monte Carlo methods with von Mises-Fisher and nonuniform densities simulations.

In recent years, wireless positioning and tracking devices based on semiconductor micro electro-mechanical system (MEMS) sensors have successfully integrated into the consumer electronics market. Information from the sensors is processed by an attitude estimation program. Many of these algorithms were developed primarily for aeronautical applications.

ASIC Design for Wireless Surgical MEMS Device and Instrumentation.

There is an increasing demand on computerized surgical instrumentation and implants that can acquire intra-operative or in-vivo data for surgeons and engineers. The sensory system is gaining complexity in order to obtain more accurate measurements. Although many off-the-shelf components and chips exist, multiple components are often required to achieve the desired function.
