Sliding Time Interval based MAC Protocol and its temporal validation.

ACM Trans. Embed. Comput. Syst.

2013

This article deals with the formal validation of STIMAP, a medium access protocol that has been designed to meet the specific requirements of an implantable network-based neuroprosthesis. This article presents the modeling and the validation of its medium access, using model checking on Time Petri Nets. Doing so, we show that existent formal methods and tools are not perfectly suitable for the validation of real systems, especially when some hardware parameters have to be considered. This article then presents how these difficulties have been managed during the modeling and verification phases, and gives the validation results for STIMAP, providing constraints to respect.

Formal Validation of a Deterministic MAC Protocol

“…The implantation of the wole interpreted generalized PN with time, on an 0.35 µm technology ASIC, has been estimated to 10 mm 2 . We have also realized the specification and FPGA-based implementation of a specific (patented) MAC protocol [22]. This protocol is exploited for several applications like implanted distributed FES, external distributed FES, wireless testing of SIP, etc.…”

Petri Net Based Rapid Prototyping of Digital Complex System

This paper deals with the automatic translation of interpreted generalized Petri Nets with time into VHDL, for rapid prototyping on programmable logic device purposes. This approach is based on the component orientation of the VHDL language, and defines two elementary VHDL components: the place and the transition. This transition component is a "pivot" element of the approach, since it supports all the interconnections between places and transitions (i.e. it allows the structure of the PN to be built). Moreover, with the aim to reduce power consumption, we proposed to control the VHDL component's activity according to an approach based on the "activity propagation" principle since PNs are oriented graphs.

“…The physical layer used for a given unit depends on the medium over which the unit communicates. The medium access control (MAC) layer, which imposes a deterministic access over the medium [5], is the same for all units in the architecture. Finally, the applicative layer varies depending on the considered unit's type.…”

Computer-based remote programming and control of stimulation units

2011 5th International IEEE/EMBS Conference on Neural Engineering

Guiraud

2011

This paper describes the architecture of the functional electrical stimulation systems developed in the context of the TIME European project. Contributions are the definition of a generic FES architecture and the specialization of this architecture, depending on the applicative context, by the deployment, the programming and the control of hardware units, notably stimulation ones. This specialization process is managed by a dedicated software environment, named SENIS Manager.
