In various embodiments, a method includes receiving, by a communication application executing on a first node of a mesh network, a message; determining, by the communication application, a second node in the mesh network to transmit the message to, the second node being a neighbor of the first node; determining, by the communication application based on a history of forward error correction (FEC) and non-FEC transmissions with the second node, that FEC or non-FEC should be used to transmit the message; and transmitting, by the communication application, in response to determining that FEC or non-FEC should be used to transmit the message, the message to the second node using FEC or non-FEC.

Policy-based failure handling for edge services

Techniques for policy-based failure handling of data that is received for processing by failed edge services are described herein. The techniques may include receiving, at an edge node of a network, a data handling policy for a service hosted on the edge node. The service may be configured to process traffic on behalf of an application hosted by a cloud-based platform. In some examples, the data handling policy may be stored in a memory that is accessible to the edge node. The techniques may also include receiving traffic at the edge node that is to be processed at least partially by the service. At least partially responsive to detecting an error associated with the service, the edge node may cause the traffic to be handled according to the data handling policy while the service is experiencing the error.

BODY-WORN VITAL SIGN MONITOR

The invention provides a body-worn monitor featuring a processing system that receives a digital data stream from an ECG system. A cable houses the ECG system at one terminal end, and plugs into the processing system, which is worn on the patient's wrist like a conventional wristwatch. The ECG system features: i) a connecting portion connected to multiple electrodes worn by the patient; ii) a differential amplifier that receives electrical signals from each electrode and process them to generate an analog ECG waveform; iii) an analog-to-digital converter that converts the analog ECG waveform into a digital ECG waveform; and iv) a transceiver that transmits a digital data stream representing the digital ECG waveform (or information calculated from the waveform) through the cable and to the processing system. Different ECG systems, typically featuring three, five, or twelve electrodes, can be interchanged with one another.
