Cardiac device wearers should maintain distance from smartphones, says a research

London: If you wear a cardiac device such as a pacemaker, better keep away from smartphones, researchers say.

“Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working,” said first author Carsten Lennerz from German Heart Centre, Munich.

“This leads to a pause in the cardiac rhythm of the pacing dependent patient and may result in syncope.”

“For implantable cardioverter defibrillators (ICDs) the external signal mimics a life threatening ventricular tachyarrhythmia, leading the ICD to deliver a painful shock,” Lennerz said.

Device manufacturers and regulatory institutions including the US Food and Drug Administration (FDA) recommend a safety distance of 15 to 20 cm between pacemakers or ICDs and mobile phones.

Now, new cardiac devices are in use including ICDs, cardiac resynchronisation therapy (CRT) and MRI compatible devices.

The current study evaluated whether the recommended safety distance was still relevant with the smartphones, networks and cardiac devices.

A total of 308 patients (147 pacemakers and 161 ICDs, including 65 CRTs) were exposed to the electromagnetic field of three common smartphones (Samsung Galaxy 3, Nokia Lumia, HTC One XL), which were placed on the skin directly above the cardiac device.

The actions were performed in GSM, LTE and UMTS at the maximum transmission power and at 50 Hz, a frequency known to influence cardiac implantable electronic devices. Electrocardiograms (ECGs) were recorded continuously and checked for interference.

More than 3,400 tests on EMI were performed. One out of 308 patients (0.3 percent) was affected by EMI caused by smartphones.

This patient’s MRI compatible ICD misdetected electromagnetic waves from the Nokia and HTC smartphones operating on GSM or UMTS as intracardiac signals.

“Interference between smartphones and cardiac devices is uncommon but can occur so the current recommendations on keeping a safe distance should be upheld.”

“Interestingly, the device influenced by EMI in our study was MRI compatible which shows that these devices are also susceptible.”

The results were presented at the joint meeting of the European Heart Rhythm Association (EHRA) and Cardiostim, which is in Milan, Italy. (IANS)

Shenzhen Based Smartphone Maker Coolpad Asked Rival Xiomi To Stop Manufacturing Devices That Infringe Upon Patents

The handset maker's subsidiary named Yulong filed a fresh suit which alleged that Xiaomi has infringed upon its patents related to dual-SIM card support and User Interface (UI) design.

Shenzhen-based smartphone maker Coolpad said on Thursday that its rival Xiaomi has to immediately stop selling and manufacturing devices that infringe upon many of its patents — more than two weeks after it locked horns with the Chinese competitor.

The handset maker’s subsidiary named Yulong filed a fresh suit which alleged that Xiaomi has infringed upon its patents related to dual-SIM card support and User Interface (UI) design.

Highlighting that Coolpad is hopeful of Xiaomi putting an end to patent infringement, Nancy Zhang, Global Chief Patent Officer, Coolpad, told IANS in an interview that we are ready to actively co-operate with them to promote industrial progress but the infringement has to stop.

In terms of 5G technology, Coolpad is one of the few Chinese smartphone makers to engage in standard setting work.

“We filed for our first patent back in 1998. As you may be aware of, we have a global portfolio and the most famous one is our Android system implemented technology — the dual SIM card technology which is patented globally. We put hard efforts and took us five years of research and engineering to develop this technology,” Nancy informed.

The handset maker is looking forward to work with Xiaomi to find a better solution, strengthen intellectual property protection and create a good business environment.

Yulong Computer Telecommunication Scientific (Shenzhen) Co. Limited — a subsidiary of Coolpad — filed the lawsuit against Xiaomi Telecom Technology Co, Xiaomi Technology Co and Xiaomi Factory Co, in a Jiangsu court in China for copying its patents without authorisation.

According to the company, one of the patents involves its dual-SIM-card-dual-standby technology.

“With this (dual SIM) technology, Coolpad received the second prize for technological progress, Shenzhen Mayor Award and also the China Patent Award this is amongst the highest awards in China for recognition of technological contributions. We received these honours between 2015 and 2016,” Nancy said.

The company has filed for patent protections that includes 400 patents and 85 per cent of these are innovation patents.

The three patents which Xiaomi is alleged to have infringed upon include system interaction or UI type patents, involving interface, applications and icon configuration technologies, whose features are more visible and identifiable on the infringing mobile phones.

“This type of infringement is easy to detect and prove. All these patents involve basic communication, display and interaction functions and are difficult to be circumvented and substituted,” the handset maker said.

In three of the lawsuits filed by the company against Xiaomi, Coolpad has filed for customs protection for two patents, which are “method of mobile telecommunication device collaboration and its interface system” and “implementation method for multi-model mobile device call history interface system”.

Notably, the “method of mobile telecommunication device collaboration and its interface system” was invented by Liu Bio, Coolpad’s President of AI Academy of Yulong.

Android system became popular in 2008 and the patent by Liu is still being used by smartphones.

Globally, the smartphone maker holds 13,000 patents and 500 of them are registered and protected in the United States including those related to 5G, User Interface (UI) and Artificial Intelligence (AI).
