This paper presents the preliminary design of the integrated stimulator and telemetry subsystems for a vestibular prosthesis to restore balance function. The work is part of the European project CLONS. The stimulator is designed to provide biphasic current pulses at specified amplitude, duration and rate to stimulate the semicircular canals in the vestibular system. Power and data transfer is p...

Stimulators of soluble guanylate cyclase (sCG) are novel pharmacological agents that directly stimulate sGC. Ongoing research on sGC stimulators led to the development of the more potent and more specific sGC stimulator, riociguat. Recently, the US Food and Drug Administration has approved riociguat to treat pulmonary arterial hypertension in adults. Support for the approval of riociguat comes ...

The aim to find out and explain role Kampar Regency Government in empowering craftsmen. collection data information was done through observation, interviews documentation with qualitative analysis methods. results study prove government fostering blacksmiths a...

BACKGROUND AND PURPOSE There have been conflicting views and evidence reported in the literature concerning differences in muscle torque-generating capacities between clinical ("plug-in") console devices whose power source is provided by an electrical outlet (60 Hz, alternating current-driven) and portable electrical muscle stimulators (smaller, battery-operated stimulators). The purpose of thi...

Electrical stimulation has been suggested as a possible treatment for various functional gastrointestinal disorders (FGID). This paper presents a transcutaneous power supplied implantable electrical stimulation system. This technology solves the problem of supplying extended power to an implanted electrical stimulator. After implantation, the stimulation parameters can be reprogrammed by the ex...

The olfactory system of an insect brain codes for information about odorant quality and quantity using the temporal pattern of neural activity as well as neurons' firing. Although an accurate odor temporal pattern is indispensable for investigations of olfactory systems, it is difficult to control in conventional odor stimulators. To overcome this problem, we fabricated an odor stimulator that ...

A large number of applications exist for Multipolar stimulation. But the main difficulty for this kind of stimulation is the stimulator which has to be able to generate accurate stimulation current and to share this current between the different cathodes. In this paper we propose an electrical evaluation of the micro-stimulator we have developed. To do this, we have conducted several experiment...

Functional electrical stimulation has been applied to restore the muscle activity of paralyzed patients who suffer from spinal cord injuries and related neural impairments for several decades. In this paper, a direct-synthesized arbitrary waveform stimulator for multichannel FES applications is described. A novel element-envelope method is proposed. A digital signal processor is chosen to synth...

We produced a miniaturized, multicode, multiband, and programmable light-emitting diode (LED) stimulator for wireless control of optogenetic experiments. The LED stimulator is capable of driving three independent LEDs upon reception of an infrared (IR) signal generated by a custom-made IR transmitter. Individual LED photopulse patterns are assigned to different codes of the IR signals (up to 25...

This study focuses on the design of electrical stimulator for retinal prosthesis. The stimulator must be designed such that the occurrence of electrolysis or any irreversible process in the electrodes and flexible lead is prevented in order to achieve safe stimulation over long periods using the large number of electrodes. Some types of biphasic current pulse circuits, charge balance circuits, ...
