This disclosure describes techniques for controlling spectral aggressors in a sensing device that uses a chopper amplifier to amplify an input signal prior to sampling the signal. In some examples, the techniques for controlling spectral aggressors may include generating a chopper-stabilized amplified version of an input signal based on a chopper frequency, sampling the chopper-stabilized amplified version of the input signal at a sampling rate to generate a sampled signal, and analyzing a target frequency band of the sampled signal. The chopper frequency and the sampling rate may cause spectral interference that is generated due to the chopper frequency to occur in the sampled signal at one or more frequencies that are outside of the target frequency band of the sampled signal. The techniques for controlling spectral aggressors may reduce the noise caused by the chopper frequency in the resulting sampled signal, thereby improving the quality of the signal.

Control of spectral agressors in a physiological signal monitoring device

This disclosure describes techniques for controlling spectral aggressors in a sensing device that uses a low power sleep mode to manage the power consumed by the device. In some examples, the techniques for controlling spectral aggressors may include configuring one or more of an algorithm processing rate for a processor, a buffering rate for the processor, a sampling rate for an analog-to-digital converter, an execution unit processing rate for the processor, and an algorithm subdivision factor for the processor such that spectral interference caused by a sleep cycle rate of the processor occurs outside of one or more target frequency bands of a sampled signal. The techniques of this disclosure may be used to reduce noise in a sensing system that uses a low power sleep mode to manage the power consumed by the device.

Control of spectral agressors in a physiological signal montoring device

Bioelectrical signals may be sensed within a brain of a patient with a plurality of sense electrode combinations. A stimulation electrode combination for delivering stimulation to the patient to manage a patient condition may be selected based on the frequency band characteristics of the sensed signals. In some examples, a stimulation electrode combination associated with the sense electrode combination that sensed a bioelectrical brain signal having a relatively highest relative beta band power level may be selected to deliver stimulation therapy to the patient. Other frequency bands characteristics may also be used to select the stimulation electrode combination.

Apparatus and method support the configuration and testing of therapy parameters for a medical device system in the treatment of nervous system disorders. With the embodiment, the medical device system operates in a manual treatment therapy mode, in which the medical device system evaluates a set of information that is indicative of a system configuration. The medical device system determines if the set of information is acceptable. During the manual treatment therapy mode, the medical device system applies therapeutic treatment to a patient in accordance with the set of information. If the patient cannot tolerate the therapeutic treatment, the user indicates so through a user interface. The medical device system may associate the patient's intolerance to therapeutic treatments that equal or exceed the patient's level of tolerance. Moreover, the medical device system may use this information to prevent a delivery of therapeutic treatment that exceeds the patient's level of tolerance during a run mode.

Configuring and testing treatment therapy parameters for a medical device system

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.

Channel-selective blanking for a medical device system

A golf club such as a mallet-style putter has a series of stepped concentric circular cavities formed in the top surface thereof at a generally transversely centered position offset rearwardly from the face of the club to afford improved alignment and optionally convert the putter for use as a training aid by supporting a carried ball on the cavities such that the carried ball will rock or be dislodged if the putting stroke accelerates or decelerates too quickly.
