First Claim
1. A distributed real-time wireless neural interface, comprising:
- a reader outputting and receiving radio-frequency signals; and
an array of distinct recording devices, at least two of the recording devices comprising;
a wireless section comprising;
an rf power converter for converting radio frequency signals into power signals;
an antenna receiving the radio-frequency signals output by the reader and providing the radio-frequency signals to the rf power converter wherein the rf power converter converts such radio-frequency signals to power signals;
a regulator receiving the power signals and regulating such power signals to provide stable power signals; and
a modulator receiving the power signals and in communication with the antenna for utilizing the antenna to communicate with the reader;
a sensor section receiving the stable power signals and adapted to detect neural activity and provide output signals containing information indicative of such neural activity to the modulator of the wireless section whereby the modulator communicates the information in the output signals to the reader.

Abstract
A distributed real-time wireless neural interface including a reader and an array of distinct recording devices. The reader outputs and receives radio-frequency signals. The array of distinct recording devices include a wireless section and a sensor section. The wireless section includes an rf power converter, an antenna, a regulator, and a modulator. The rf power converter converts radio frequency signals into power signals. The antenna receives the radio-frequency signals output by the reader and provides the radio-frequency signals to the rf power converter wherein the rf power converter converts such radio-frequency signals to power signals. The regulator receives the power signals and regulates such power signals to provide stable power signals. The modulator receives the power signals and is in communication with the antenna for utilizing the antenna to communicate with the reader. The sensor section receives the stable power signals. The sensor section is adapted to detect neural activity and provide output signals containing information indicative of such neural activity to the modulator of the wireless section whereby the modulator communicates the information in the output signals to the reader.
