Corresponding author, Email: [email protected] ABSTRACT In this paper, we present a preliminary research effort towards an effective computer support environment for the design and development of micro-electro-mechanical systems (MEMS). We first identify the characteristics of MEMS product design and development processes and examine the state-of-the-art of MEMS Computer-aided Design (CAD) and s...

Estimating the range between an acoustic source and a microphone is a central problem in microphone-array processing. Although many approaches have been proposed in the literature, these tend to require knowledge of the relative microphone positions. We propose a range estimation method, for use in reverberant environments and where the relative positioning of the elements of a microphone-array...

We propose a novel information-theoretic approach for evaluating microphone arrays that relies on the array physics and geometry rather than the underlying beamforming algorithm. The analogy between Multiple-Input-Multiple-Output (MIMO) wireless communication channel and the acoustic channel of microphone arrays is exploited to define information measures of microphone arrays, which provide upp...

Curriculum development in microelectromechanical systems (MEMS) in the Mechanical Engineering and Applied Mechanics (MEAM) Department at the University of Michigan is presented. A course curriculum structure that integrates both mechanical and electrical engineering courses is proposed for mechanical engineering students. The proposed curriculum starts from undergraduate study and finishes at t...

This paper presents a general method for the integration of distributed microphone arrays for localization of a sound source. The recently proposed sound localization technique, known as SRP-PHAT, is shown to be a special case of themore general microphone array integrationmechanism presented here. The proposed technique utilizes spatial likelihood functions (SLFs) produced by each microphone a...

Automatic directionality algorithms currently implemented in hearing aids assume that hearing-impaired persons with similar hearing losses will prefer the same microphone processing mode in a specific everyday listening environment. The purpose of this study was to evaluate the robustness of microphone preferences in everyday listening. Two hearing-impaired persons made microphone preference ju...

Getting Micro-Electro-Mechanical Systems (MEMS) out of a wafer after fabrication processes is of great interest in testing, packaging or simply using these devices. Actual solutions require special machines like wafer dicing machines, increasing time and cost of de-tethering MEMS. This article deals with a new solution for manufacturing mechanical de-tetherable silicon MEMS. The presented solut...
