Systems, methods, and devices are provided for suppressing cross-talk noise due to capacitive and/or inductive coupling in a medical sensor signal. For example, an embodiment of a patient monitor may include driving circuitry, an amplifier, and transient current discharge circuitry. When the driving circuitry drives an emitter to emit light into a patient, a detector may detect a portion of the light that passes through the patient, generating a detector signal. Cross-talk between the emitter driving signals and the detector signal may generate interference in the form of a transient current in the detector signal. Before the amplifier receives the detector signal, transient current discharge circuitry may discharge the transient current.

Systems and methods form and control a supercomputer based upon a parallel processing architecture such as a Howard cascade. A graphical user interface allows a user to interact with one or more virtual power centers of the supercomputer facility. A plurality of processing nodes self-organize into one or more virtual power centers. The processing nodes utilize overlapped input and output for improved communication.

Systems, methods, and devices for improved patient monitor signal processing with higher signal-to-noise ratio (SNR) are provided. In accordance with an embodiment, an electronic patient monitor may include drive circuitry, a current-to-voltage converter, and feedback circuitry. The drive circuitry may drive an emitter of a medical sensor with dark periods during which the emitter does not emit light, and the current-to-voltage converter may receive and amplify a photocurrent signal from a detector of the sensor. The feedback circuitry may provide a feedback signal to the current-to-voltage converter. The feedback signal, based at least in part on the output of the current-to-voltage converter during the dark periods, may cause the current-to-voltage converter to substantially exclude an ambient light component of the photocurrent. As a result, the current-to-voltage converter may employ a higher transimpedance without distorting the output voltage signal due to oversaturation, and thus may achieve a higher SNR.

Embodiments of the present disclosure relate to a system and method for reducing power consumption of a medical device based on one or more physiological parameters. For example, the medical device may be operated in a low power mode if a physiological parameter trend is above a certain threshold. In the low power mode, the processing power may be reduced relative to a high power mode. The low power mode may be associated with reduced processing and output rate.

Systems, methods, and devices are provided for reducing power consumption of a medical sensor system. In an embodiment, a patient monitor may include driving circuitry to drive an emitter of a sensor to emit light into a patient in accordance with a power-reducing timing cycle. For example, the power-reducing timing cycle may include emitting periods in which the emitter emits light and dark periods in which the emitter does not emit light. In certain embodiments, the dark periods may occur for a longer duration than the emitting periods.
