Electroencephalograph incorporating at least one wireless link
First Claim
1. An improved electroencephalograph system for telemetrically transmitting data to a selected receiver, said data being detected by a plurality of sensors selectively attached to a subject in a selected arrangement, said improved electroencephalograph system comprising:
- a first receiving means for receiving said data detected by said plurality of sensors, said data including signals indicating brain activity of said subject and used for selective monitoring of said subject;
processing means for converting said data into a selected digital code suitable for telemetric transmission, said selected digital code being Manchester code;
transmitting means for transmitting said coded data to said selected receiver at a selected frequency;
second receiving means carried by said selected receiver to receive said coded data transmitted by said transmitting means;
decoding means in communication with said second receiving means for decoding said coded data transmitted by said transmitting means; and
user interface means for performing selected functions using said decoded data for continuous display/recording thereof.

Abstract
An improved EEG system (10) for telemetrically transmitting brain activity data from a portable transmitter to a processing console. The improved EEG system (10) includes a lightweight transmitter (12) which amplifies and digitizes the EEG signals from a set of electrodes (16) and transmits the digital signals along with a checksum to a receiver (14). The transmitter (12) may be carried by the subject under observation. The transmitter (12) of the preferred embodiment includes at least four circuit boards including a selectively interchangeable montage board (18), an amplifier board (24), a processor board (34), and a transmitter board (54). A signal is transmitted toward the receiver (14) and delivered to a conventional computer-controlled broadcast television tuner (80). The selected receiver (14) outputs data which is in an acceptable form for connection to standard microprocessor peripherals. The incoming data is processed and inspected to verify the validity thereof with any invalid data being marked as invalid. All data is then continuously and simultaneously displayed and recorded, with any invalid data being easily recognized as such and therefore disregarded.

12. A method of telemetrically transmitting signals sensed using an improved electroencephalograph system for transmitting data to a selected receiver, said method of telemetrically transmitting signals comprising the steps of:
-
sensing said signals by a plurality of sensors selectively attached to a subject in a selected arrangement; sending said signals to a selected processing means; amplifying said signals within said processing means; generating a selected indicator for simultaneous processing with said amplified signals; converting said amplified signals and said selected indicator into a selected digital code suitable for telemetric transmission, said selected digital code being Manchester code; transmitting said coded signals and said coded indicator at a selected frequency; receiving said coded signals and said coded indicator by a selected receiving means; decoding said coded signals and said coded indicator; comparing said selected indicator with said decoded indicator; identifying said decoded signals transmitted simultaneously with said decoded indicator when said decoded indicator varies from said selected indicator generated by said generator means; and selectively and continuously displaying and recording said decoded signals. - View Dependent Claims (13, 14)
