In one example, a method includes calculating a signal to noise ratio of a captured audio stream, determining that the signal to noise ratio of the captured audio stream is lower than a predefined threshold, acquiring visual data of a source of the captured audio stream in response to the determining that the signal to noise ratio of the captured audio stream is lower than the predefined threshold, using the visual data to infer a sound that is being made by the source of the captured audio stream, indexing the sound that is being made by the source of the captured audio stream to a library index, and transferring the library index to a receiving user endpoint device.

Leveraging visual data to enhance audio reception

Aspects of the subject disclosure may include, for example, identifying, during a CPU's execution of a first program, a branching instruction of the first program that redirects execution to a second program. Responsive to the identifying of the branching instruction, a return address of a next instruction of the first program is encrypted. The encrypted return address is transferred to the second program without the CPU retaining a record of the return address. The encrypted return address is received from the second program responsive to its completion of execution. The received encrypted return address is decrypted to obtain the return address enabling a resumption of execution of the first program from the next instruction. Other embodiments are disclosed.

Secure CPU architecture using encryption of return addresses

Facilitation of communication of radio resource quality to a mobile application is provided. In one example, a method comprises: determining, by a device coupled to a processor, a peak-to-average loading ratio of a loading of a radio of a base station device and a mobility factor of the radio, wherein the loading relates to an amount of data being handled by the radio; and determining, by the device, class information for the radio of the base station device, wherein the class information comprises a value indicative of the peak-to-average loading ratio and the mobility factor of the radio, wherein the class information is correlatable to a bit rate at which a mobile device is to execute an application of a mobile device, and wherein the radio is communicatively coupled to the mobile device.

Facilitating communication of radio resource quality to a mobile application

A proximity-based security mechanism can control access to the programming interface of an implanted medical device. The security mechanism prevents unauthorized remote access to the programming interface by hackers or other hostile individuals, securing the safety of the subject. The system also allows the subject or other responsible person to activate the programming interface when changes to the operation of the implanted medical device are needed. In one example, a security interface is operable to detect, while implanted in the subject, an activation signal produced in close proximity to the subject, and activate the programming interface in response to the activation signal so that the implantable medical device can receive the programming instructions. A proximity-based security mechanism can be a dedicated device, or can be implemented in a programmable computing device such as a smartphone or other mobile computing device.
