How Impulse Works

The Impulse sensor
The Impulse sensor is an EMG (Electromyography) sensing electrode that senses EMG activity, which is made up of tiny electrical potentials that are produced by muscles and the nervous system when muscle contractions occurs. Using its patented ProActive technology, the Impulse sensor amplifies, digitizes and transmits the EMG signal at the electrode site. Specialized software runs on a Microsoft Windows compatible computer that wirelessly receives the signal. When volitional muscle control is detected, a virtual switch “hit” is passed to special software allowing users to control their computer. The Impulse can also function as an alarm that alerts caregivers to the needs of the user.

More Specifically…
The Impulse sensor snaps onto a disposable electrode that adheres to the skin. The electrodes are small pads with a sticky side which allow the sensor to receive and transmit muscle activity. The computer receives this information, and when used in conjunction with communication software such as EZ-Keys and Eye Response (sold separately), enables users to control their computer - effectively replacing the keyboard and mouse. This allows paralyzed users to remain functional, accomplishing task such as emailing, research, online investing, shopping, and more.

The Bluetooth connection
Impulse uses Bluetooth wireless technology to send a reliable signal to the computer without any need to “point” the device. Impulse ships with a small, USB Bluetooth adapter, easily turning your current computer into a machine that Impulse can wirelessly control.

The Impulse software
The software is built using Visual Studio 2005 and runs on the .Net 2.0 Framework. Using these technologies the Impulse sensor is able to deliver virtual switch closures with an average delay of less than 25 milliseconds. It is important to note that the Impulse software is used solely to capture the switch "click" and does not provide switch access to other software. To achieve complete control of any computer, switch accessibility software must be installed separately.
