US Classification:

607 61, 607 48, 607 49, 128903

Abstract:

An input command controller (A) provides logic function selection signals and proportional signals. The signals are generated by movement of a ball member ( ) and socket member ( ) relative to two orthogonal axes. When the joystick is implanted, a transmitter ( ) transmits the signals to a patient carried unit (B). The patient carried unit includes an amplitude modulation algorithm such as a look-up table ( ), a pulse width modulation algorithm ( ), and an interpulse interval modulation algorithm ( ). The algorithms derive corresponding stimulus pulse train parameters from the proportional signal which parameters are transmitted to an implanted unit (D). The implanted unit has a power supply ( ) that is powered by the carrier frequency of the transmitted signal and stimulation pulse train parameter decoders ( ). An output unit ( ) assembles pulse trains with the decoded parameters for application to implanted electrodes (E). A laboratory system (C) is periodically connected with the patient carried unit to measure for changes in patient performance and response and reprogram the algorithm accordingly.

US Classification:

607 48

Abstract:

An input command controller (A) provides logic function selection signals and proportional signals. The signals are generated by movement of a ball member (12) and socket member (14) relative to two orthogonal axes. When the joystick is implanted, a transmitter (50) transmits the signals to a patient carried unit (B). The patient carried unit includes an amplitude modulation algorithm such as a look-up table (124), a pulse width modulation algorithm (132), and an interpulse interval modulation algorithm (128). The algorithms derive corresponding stimulus pulse train parameters from the proportional signal which parameters are transmitted to an implanted unit (D). The implanted unit has a power supply (302) that is powered by the carrier frequency of the transmitted signal and stimulation pulse train parameter decoders (314, 316, 318). An output unit (320) assembles pulse trains with the decoded parameters for application to implanted electrodes (E). A laboratory system (C) is periodically connected with the patient carried unit to measure for changes in patient performance and response and reprogram the algorithm accordingly.

International Classification:

A61B 50476

US Classification:

128731

Abstract:

A wireless EEG system for effective auditory evoked response, comprising an electrode array which is adapted to be attached to a person and senses voltages produced by the brain electrical activity of the person; transmitter electrically connected to the electrode array such that the transmitter produces a radio frequency signal corresponding to the voltages sensed by the electrode array, encodes the radio frequency signal with error correcting encoding and transmits the radio frequency signal by radio frequency telemetry through a transmitting antenna; the transmitter utilizing carrier frequency shift keyed circuitry to modulate a phase locked loop synthesized carrier frequency and reference frequency shift keyed circuitry to modulate a reference frequency to allow for non-return to zero format of the radio frequency signal obviating the need for Manchester encoding; receiver that receives through a receiving antenna the radio frequency signal produced and transmitted by the transmitter and whereby the receiver decodes the radio frequency signal and produces a data output corresponding to the radio frequency signal received by the receiver; and an operator interface connected to the receiver such that the operator interface receives as input the data output produced by the receiver such that the operator interface records a verbal stimulus given by an individual and provides an auditory stimulus whereby the operator interface displays the data output, such display providing a comparison of the brain electrical activity in response to said stimulus.
