    摘要： A patient state is detected with at least one classification boundary generated by a supervised machine learning technique, such as a support vector machine. The patient state can be, for example, a patient posture state. In some examples, the patient state detection is used to at least one of control the delivery of therapy to a patient, to generate a patient notification, to initiate data recording, or to evaluate a patient condition. In addition, an evaluation metric can be determined based on a feature vector, which is determined based on characteristics of a patient parameter signal, and the classification boundary. Example evaluation metrics can be based on a distance between at least one feature vector and the classification boundary and/or a trajectory of a plurality of feature vectors relative to the classification boundary over time.

    摘要： Apparatuses and methods selectively blank a neurological channel of a medical device system in the treatment of a nervous system disorder. A selected signal of a selected channel may be blanked if it is determined that the selected signal may be affected by an artifact when the medical device system delivers a treatment therapy. The selected signal may be blanked by hardware, in which the selected electrode is disconnected from the selected channel (which may include an selected amplifier) and is connected to a fixed voltage in order to avoid saturation of the selected amplifier. The selected channel may be blanked by software, in which a signal processor is instructed not to process neurological data on the selected channel for a determined time duration. Embodiments may combine hardware and software blanking for the selected signal.
