Abstract: Systems, methods, and devices involve approaches for limiting the number of detected cardiac events for which a physician is alerted. Approaches involve detecting cardiac events based on electrocardiogram (ECG) data and associating the cardiac events with a criticality. ECG data associated with a subset of the cardiac events is transmitted to a remote computing system based, at least in part, on the criticality. An electronic notification is transmitted to a patient care group regarding at least one of the cardiac events in the subset. Approaches further include determining whether an acknowledgement of the electronic notification has been received by the server from the patient care group within a set period of time.

Abstract: Techniques for liquid cooling systems are disclosed. In one embodiment, jet holes in a water block create jets of liquid coolant to be applied to a surface to be cooled, such as a surface of an integrated circuit component. The jets of liquid coolant may disrupt surface boundary layers through turbulence and/or microcavitation, increasing the cooling effect of the liquid coolant. In the illustrative embodiment, negative pressure is applied to a coolant loop of the liquid coolant, which provides several advantages such as being resistant to leaks. In another embodiments, jet holes in a water block create jets of liquid coolant that are directed toward other jets of liquid coolant, which also increases the cooling effect of the liquid coolant.

Abstract: A device is configured to detect multiple different wakewords. A device may operate a joint encoder that operates on audio data to determine encoded audio data. The device may operate multiple different decoders which process the encoded audio data to determine if a wakeword is detected. Each decoder may correspond to a different wakeword. The decoders may use fewer computing resources than the joint encoder, allowing for the device to more easily perform multiple wakeword processing. Enabling/disabling wakeword(s) may involve the reconfiguring of a wakeword detector to add/remove data for respective decoder(s). Specific decoders may be activated/deactivated depending on device context, thereby efficiently managing device resources.
