Catheters can contain tools to vaporize or "ablate" bits of heart tissue that cause abnormal signals that control the heartbeat.
Applying an electric current and getting a muscle to jump is easy. (Alessandro Volta jolted a frog's legs 218 years ago.) Peckham is harvesting the body's own electrical signals to control muscles that have been cut off from the nervous system, a process called functional electrical stimulation, or FES. Peckham runs a group called the Cleveland FES Center, a collaboration among Case Western Reserve and two Cleveland hospitals.
"Any mechanical motion, such as the movement of arms or the fingers of a robot, could be translated to control signals, " said Zhong Lin Wang, a professor at the Georgia Institute of Technology.
"This is a really small microchip and on this chip we've got the intelligence which can actually model the neural signals responsible for appetite control, " Prof Toumazou told the BBC.
For easy operation while viewing movies or television, the system offers an advanced multi-language on-screen display that overlays onto HD and 3D video signals to depict system control and setup prompts.

One way this can be successfully accomplished is by "multiplexing" the electrodes normally used to relay touch input -- that is, using the same electrodes to handle the signals for both touch control and the pixels of the LCD, according to a 2010 IHS report on touch-screen displays.
Studies in animals have shown that signals from this nerve can control the new bladder reflex.
The hand itself has several degrees of motion, and is controlled using the same nerve signals that are used to control a biological hand.
Alcohol directly affects brain chemistry by altering levels of neurotransmitters the chemical messengers that transmit the signals throughout the body that control thought processes, behavior and emotion.
Mission Control analyses numerous signals relating to the vehicle, the driving situation and the vehicle's surroundings to provide the driver with relevant information and advice, all generated in dialogue form.

The launchers can be up to a kilometre away from the radar and control hub, linked by microwave signals.
Unlike other aircraft where the pilot's controls are manually attached to the flaps and rudders, Airbus 330 airliners are equipped with a "fly by wire" system that sends electronic signals from an onboard computer to move key control surfaces.
The Assad regime, which is backed by Russia and Iran, has sent several signals in recent weeks that it intends to control terms of any potential talks with the opposition, and that discussing the fate of Mr. Assad is off the table.
All planes have batteries, but the Dreamliner needs especially powerful ones because its control systems are driven entirely by electrical signals in place of the hydraulic controls seen on earlier generations of jet.
The Control It All Remote transceiver then converts Bluetooth signals from the smartphone into infrared signals for the devices.

The mines are made cheaply from fertiliser, syringes and building materials and can be detonated by pressure devices such as tripwires, or by remote control using radio frequencies or mobile-phone signals.
The BrainLab was one of the first to demonstrate that a person can control a robotic arm and a wheelchair with brain signals, Jackson said.
It sounds unbelievable, but the technology actually relies on understood phenomena, exploiting the electrical signals produced by the brain as well as eye movement to control electronic devices.
And we have rope tenders that control us on the surface and give us particular signals and tell us where to turn and things of that nature, because with no visibility you normally will lose your sense of direction and everything else.
The rich world's electric networks are currently midstream between an old command-and-control world and a brave new liberalised world of market signals and competition.
The object information is then processed and passed on to the Continental Motion Domain Controller to control the vehicle's longitudinal and lateral motion via signals to the engine, the brakes and the steering system.

Some geneticists have complained that this arrangement not only inconveniences their work, but signals that it is acceptable to lay claim to genetic information and to control its exploitation.
Such second-hand signals are not as precise as ones collected directly from the brain itself, and probably could not control the complex movements required of an arm and a hand.
But some security researchers imagine a less sensational, if equally troubling possibility: Hundreds or thousands of aircraft radioing their approach to an air traffic control tower, and no way to sort through which are real and which are ghost plane signals crafted by a malicious hacker.
