A HUGE STEP FORWARD
NEUROPROSTHETIC ALLOWS A TETRAPLEGIC PATIENT, FITTED WITH AN EXOSKELETON, TO MOVE
F
or the first time, a tetraplegic patient was able to walk
and control both arms using a neuroprosthetic, which records, transmits, and decodes brain signals, in real-time, to enable the control of assisted limbs. The results of a clinical study, under the Brain Computer Interface (BCI) Project at Clinatec, were published on 4 October 2019 in The Lancet Neurology journal and provide proof of this concept.
The system is driven via the
long-term implant of a semi- invasive medical device to record brain activity developed at the
CEA in Grenoble. In the long term, this technology is expected to give greater mobility to individuals with severe motor disabilities. Since the operation, the patient has spent 27 months performing various types of exercises, to practice and harness control over the exoskeleton. He practices in virtual environments, with the exoskeleton avatar at home, three times a week, working with the exoskeleton directly at Clinatec one week every month. When fitted with the suspended exoskeleton, he is able to take several successive steps and control his two upper
limbs in three dimensions. He can also rotate his wrists while sitting or standing.
The device – WIMAGINE - was designed for semi-invasive implantation in the cranium, in order to record electrocorticograms (ECoG) over the long term using an array of 64 electrodes in contact with the dura mater. This activity, relevant to the moving intention, is transmitted wirelessly and in real-time, to a computer for decoding: this complex yet quick
process enables the control of the exoskeleton’s four limbs. The long-term goal is to identify
fields in which the brain-machine interface could be used to create compensatory systems for various types of motor disabilities, and give patients more independence in their everyday lives, for example, by driving a wheelchair or controlling an articulated arm.

RFS’ CTO focusing on 5G C
ole joined RFS in 2018 as VP of base station antennas, bringing 35 years of experience in the RF/microwave industry. During his first 18 months with RFS, he has already refined RFS’ approach to product management to focus on customer driven solutions for 5G. RFS technology and innovation leadership includes the RFS’s FUSION programme, which builds on RFS’s APA (active passive antenna) launched in 2018. It allows operators to stagger the cost of 5G, deploying a passive 4G antenna today that can be seamlessly upgraded to add active 5G mMIMO capacity with plug and play modules in the future.
RFS has seen a growing demand as it has launched a comprehensive range of products and solutions dedicated to solving challenges faced by operators. Cole will build on this as RFS joins the network evolution to 5G.
RFS’ CEO, Monika Maurer, comments: “We were thrilled to welcome John into the RFS leadership team. He brings a wealth of experience and insight that perfectly supports RFS’s customer-driven approach to R&D and innovation. We look forward to seeing the company continue to go from strength to strength with John over the coming years.”

CADENCE, ARM AND SAMSUNG FOUNDRY WORK TOGETHER FOR MISSION- CRITICAL APPLICATIONS
C
adence Design Systems has collaborated with Samsung Foundry and Arm in the integration of the
next-generation Arm Hercules CPU, through Cadence’s digital flow and with the help of Samsung Foundry’s 5nm low-power early (5LPE) process technology. It is hoped that, with these technologies combined, customers can expect high-performance, high-quality designs, thanks to this enhanced 5LPE flow. A rapid
