Abstract: Methods, systems, and devices for displaying physiological data in a user interface are described. The method may include identifying a first table and displaying a first row including the first set of values for the first physiological parameter and a second row including the second set of values for the second physiological parameter. The method may further include receiving, from a medical device associated with a patient, measured values associated with the first physiological parameter and the second physiological parameter. In some cases, the method may include identifying a first display range and a second display range based at least in part on the received measured values. The method may also include displaying a first visual indicator and a second visual based on whether the first display range and the second display range visually overlap between the first row and the second row.

Abstract: A system and methods include a negative certificate authority for distributed management of negative certificates. An authorization restriction is associated with an untrusted user. A negative certificate generated for the untrusted user includes a public key associated with the untrusted user and an authorization restriction. The authorization restriction includes at least one global restriction, which is applicable to each consortium member that subscribes to the negative certificate. The authorization restriction includes at least one local restriction, which allows individual consortium members to further define their own locally applicable restrictions using the negative certificate authority. The negative certificate is accessible to each member of the consortium to enforce the authorization restriction against a transaction request. A secure contributor record including a unique cryptographically generated address is generated for each contributor.
