Abstract: An exemplary computing device includes a plurality of circuits and/or a plurality of in-situ monitors configured to generate outputs that indicate one or more operating conditions of the circuits. The computing device also includes a system management unit configured to detect a potentially faulty voltage-to-frequency ratio implemented by one of the circuits based at least in part on one or more of the outputs. The system management unit is also configured to modify the potentially faulty voltage-to-frequency ratio based at least in part on one or more of the outputs. Various other devices, systems, and methods are also disclosed.

Abstract: This specification describes technologies relating to a phone-based payment system for transferring funds between payers and payees, and methods of providing such a system. In general, one aspect is implemented as a method of electronic payment that includes receiving a payer identifier from a payer, and the payer identifier is selected from a group of a registered phone number and a registered business server identifier. The method also includes identifying the payer as an authorized user based on the received payer identifier. The method further includes authorizing a payment transfer from a bank account of the payer to a bank account of a payee if the identified payer is an authorized user. Other implementations of this aspect include corresponding systems, apparatus, and computer program products.
