Low Cost Solder Bumped Flip Chip MCM‐L Demonstration
Circuit World, 1995Co-Authors: M. KellyAbstract:A low cost multichip module employing solder bumped flip chips mounted on an organic substrate was demonstrated. This Functional Prototype was used to help assess the preliminary feasibility of low temperature solder bumped flip chip applications, from wafer design, sourcing and bumping, substrate design and fabrication, to MCM‐L assembly.

Usability Assessment of an Innovative Device in Infusion Therapy: A Mix-Method Approach Study.
International journal of environmental research and public health, 2020Co-Authors: Pedro Parreira, Liliana B Sousa, Inês A Marques, Paulo Santos-costa, Sara Cortez, Filipa Carneiro, Arménio Cruz, Anabela Salgueiro-oliveiraAbstract:Background: Flushing a venous access device is an important procedure to maintain their patency and prevent malfunctioning and complications. An innovative double-chamber syringe was developed, allowing for the assessment of catheter patency, drug delivery and final flush. This study aims to assess the usability of this new device, considering three development stages (concept, semi-Functional Prototype, Functional Prototype). Methods: An iterative methodology based on a mix-method design (qualitative and quantitative) enabled the assessment of the devices' usability by their primary end-users. A usability questionnaire was developed and applied, along with focus groups and individual interviews to nurses. Results: The usability questionnaire integrated 42 items focused on four dimensions (usefulness; ease of use; ease of learning; satisfaction and intention to use). The initial psychometric findings indicate a good internal consistency and the conceptual relevance of the items. The scores seem to be sensitive to the usability evaluation of the medical devices in different stages of product development (with lower values on Functional Prototype evaluation), and related to nurses' perceptions about Functional and ergonomic characteristics. Conclusions: Quantitative and qualitative data provided a comprehensive overview of the double-chamber syringes' usability from the nurses' point of view, informing us of features that must be addressed.

The Role of Model-Level Transactors and UML in Functional Prototyping of Systems-on-Chip: A Software-Radio Application
2005Co-Authors: Alexandre Chureau, Yvon Savaria, El Mostapha AboulhamidAbstract:Developing a Functional Prototype of a system-on-chip provides a unifying vehicle for model validation and system refinement. Keeping the Prototype executable across several abstraction levels, clock domains and design tools is a key requirement to effective prototyping. This paper presents how model-level transactors address design heterogeneity by unifying event-based and cycle-based worlds from specification to implementation. Transactors are used to build a Functional Prototype of a software-radio component. An executable UML model is bridged to a hardware abstraction of a radio stream developed with Simulink to implement a realistic and working Prototype. Model validation and performance measurements are realized through Prototype execution and real-time monitoring.

Building Heterogeneous Functional Prototypes Using Articulated Interfaces
2006 IEEE North-East Workshop on Circuits and Systems, 2006Co-Authors: Alexandre Chureau, Yvon Savaria, Jean-françois Boland, Zeljko Zilic, Claude Thibeault, Francois GagnonAbstract:A Functional Prototype is an executable specification of an integrated system that can be used for early validation and verification. This Prototype is assembled and verified using a variety of languages at different levels of abstraction. In order to preserve the integrity and executability of this heterogeneous specification, an articulated interface mechanism is presented. The appropriate decoupling of the interface provides an efficient and reusable communication component that can be used for both design refinement and verification. Experimentation shows that different parts of the model can be refined individually and exported to a target platform without compromising the Prototype integrity. A verification environment is also proposed to perform unit verification in a heterogeneous environment.

WIMAGINE: an implantable electronic platform for wireless 64-channel ECoG recording
Bio-MEMS and Medical Microdevices, 2013Co-Authors: M. Foerster, Jean Porcherot, S. Robinet, R. D'errico, V. Josselin, Fabien Sauter, Corinne Mestais, Guillaume CharvetAbstract:The WIMAGINE platform was developed as a proof of concept and first Functional Prototype of an implantable device for recording ECoG signals on a large number of electrodes. The designed system provides the means of recording wirelessly up to 64 ECoG channels. Two ASIC CINESIC32 ensure the amplification and digitization of the neurosignals which are then transmitted to a PC using a ZL70102 transceiver in the MICS band. An MSP430 handles the communication protocol, configures the ASICs and gives access to various sensor information. The electronics are packaged hermetically in a biocompatible titanium housing encapsulated medical grade silicone. The whole device is powered remotely over an inductive link at 13.56MHz and complies with the regulations applicable to class III AIMD.
