摘要： A sensor-effector system includes an array of sensor-effector transducers providing a plurality of sensed signals and applying a plurality of effector signals. The array provides signals to input signal conditioning circuitry which digitizes and filters the plurality of sensed signals. A processor receives the digitized signals, and processes them to generate multiple feature vectors. It also analyzes the feature vectors to identify patterns and classify the identified patterns and generates at least one response vector resulting from the recognized pattern. The response vector is applied to output signal conditioning circuitry, coupled which converts the response vector to at least one analog signal which is applied as an effector signal to the array of sensor-effector transducers.

摘要： An implantable sensor array incorporates active electronic elements to greatly increase the number of sensors and their density that can be simultaneously recorded and activated. The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors/effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors/effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors/effectors on the array.

摘要： A method and an apparatus for predicting and detecting epileptic seizure onsets within a unified multiresolution probabilistic framework, enabling a portion of the device to automatically deliver a progression of multiple therapies, ranging from benign to aggressive as the probabilities of seizure warrant. Based on novel computational intelligence algorithms, a realistic posterior probability function P(ST|x) representing the probability of one or more seizures starting within the next T minutes, given observations x derived from IEEG or other signals, is periodically synthesized for a plurality of prediction time horizons. When coupled with optimally determined thresholds for alarm or therapy activation, probabilities defined in this manner provide anticipatory time-localization of events in a synergistic logarithmic-like array of time resolutions, thus effectively circumventing the performance vs. prediction-horizon tradeoff of single-resolution systems. The longer and shorter prediction time scales are made to correspond to benign and aggressive therapies respectively. The imminence of seizure events serves to modulate the dosage and other parameters of treatment during open-loop or feedback control of seizures once activation is triggered. Fast seizure onset detection is unified within the framework as a degenerate form of prediction at the shortest, or even negative, time horizon. The device is required to learn in order to find the probabilistic prediction and control strategies that will increase the patient's quality of life over time. A quality-of-life index (QOLI) is used as an overall guide in the optimization of patient-specific signal features, the multitherapy activation decision logic, and to document if patients are actually improving.
