Microphone is a critical component for seamless communication converting an acoustic signal (vocal) to an electrical signal. Traditionally Electrets Condenser Microphones (ECM) have been the primary proponent of audio component in many consumer products. With functionally rich consumer devices (example smart phones, etc) there is a growing trend to look at components with higher functionality but a smaller form factor. Microelectronic Mechanical Systems (MEMS) microphone is seen as a possible replacement to ECM due to its significant reduction in form fit with additional functionality. The paper is an effort to illustrate steps that can be considered while designing MEMS microphone in a system. This includes Design considerations, Reliability tests, Manufacturing challenges and Readiness to ensure higher yield during the final assembly. Manufacturing issues (Top 5) and guideline presented in the paper are not just to increase the assembly yield (system level), but also to increase an awareness upfront to the design phase to help create a robust system/product.

AbstractToys are children's first consumer products and while playing they acquire numerous skills, learn about their environment and socialise with other children and adults. Toys are adapted and used by clinicians as therapeutic devices because they allow them to create bonds and communicate with children. Aesthetical aspects should be considered early in the design process, especially since pre-schoolers’ views are still dominated by the appearance of artefacts, also known as, the perceptual salient characteristics. The study of emotions mediates the understanding of the relationships between a product, user and the process with which consumers set up preferences over products. Decisions taken in each design stage will influence whether therapeutic devices will be enjoyed by children. An experiment was carried out to test out pre-schoolers’ preferences on individual attributes: form, dimension, material (hardness and weight) and surface (appearance and texture). This study exposed dominant characteristic preferences and the fact that some are influenced by gender and age. Employing these findings in therapeutic devices will enable clinicians to better engage the children during therapy.

The design considerations and construction for a complete tremor analyzer have been reviewed. A design description of a working analyzer is presented which uses a loudspeaker as an electro-mechanical transducer. The electrical signal is amplified, filtered, rectified, and integrated to provide a continuous minute-to-minute indication of tremor amplitude. tremor tranducer; oxotremorine Submitted on September 8, 1969

Effective Service

Abstract A few years ago, along with colleagues from Intel and Dell, we shared with you the importance of Failure Analysis as a business proposition[1], This paper will identify even more business processes which will benefit from a robust System Level Failure Analysis framework. More and more companies strive to differentiate themselves from their competition by focusing not just on product features and price, but also on how well they serve their customers. An effective Service Plan (Figure 1) is fundamental in the provision of this service. No matter how broad a company’s service offering portfolio, a fundamental enabler of any Fault Management system is the ability to identify and predict failures. Further, a robust Knowledge Management system must exist to enable the collection and dissemination of services intellectual property (IP) in an effective manner, and facilitate a broad level commonality analysis that provides the ability to monitor trends and shifts in product performance.
