Abstract: Systems, computing platforms, and methods for sampling and analyzing common mode noise on electrocardiogram signals to help to minimize the interference to the electrocardiogram signals are disclosed. Exemplary implementations may: obtain electrocardiogram signals from one or more sensors configured to be attached to a patient and communicatively connected to a patient monitor; receive the electrocardiogram signals from one or more sensors by the patient monitor; display the electrocardiogram signals on one or more displays of the patient monitor; sample and analyze a direct current range and an alternating current spectrum to identify common mode interference levels within the obtained electrocardiogram signals; display the direct current range and the alternating current spectrum via the one or more displays of the patient monitor; and update the display of the direct current range and the alternating current spectrum in real time to identify sources of common mode interference.

Abstract: Disclosed herein are apparatuses and methods for treating neurological disorders by electro-stimulation. The apparatus (10) for treating neurological disorders includes at least one electrode (12) implantable in the brain of a patient, and a processing and stimulation device (14) connected to the at least one electrode (12). The processing and stimulation device (14) may include a stimulation module (16) configured to generate a stimulation signal to be sent to the at least one electrode (12), and an acquisition module (20) that measures cerebral activity coming from the brain of the patient. The acquisition module (20) may have a front-end block (27) configured to amplify the potential difference of its input signals (V1a, V2a) and to filter a stimulus artifact and may include a multi-stage fully-differential switched capacitor circuit (e.g., an integrated circuit) configured for discrete-time signal processing.

Abstract: A weak current signal acquisition circuit, and a seat (10) and a seat cover (100) having the circuit. The weak current signal acquisition circuit uses two signal acquisition units as front input electrodes of an amplification circuit, and uses an in-phase differential input mode, so that the ratio of amplitudes of a differential mode signal sent to a subsequent-stage operational amplifier to a common mode signal is improved, thereby achieving the purpose of improving the signal-to-noise ratio of a weak current signal extracted by a signal acquisition unit. When people use a seat cover (100) in which a weak current signal acquisition circuit is mounted, thighs are in contact with a signal acquisition unit provided on the seat (10), such that the weak current signal acquisition circuit can acquire a human body's electrocardiosignal more effectively.

Abstract: A finger wearable device for monitoring vital signs at a finger includes a housing, a finger cuff, a plurality of vital sign sensors, and an electrocardiogram (ECG) sensor. The housing includes an interface surface for pressing against the finger. The finger cuff attaches to the housing and has a size and a shape to secure the housing to the finger and force the interface surface against the finger when the finger cuff is worn around the finger. The vital sign sensors are disposed in or on the housing and orientated to measure the vital signs from the finger of a wearer. The ECG sensor is disposed in or on the housing and coupled to first and second electrodes to measure ECG signals. The second electrode is disposed on the interface surface.
