A method for Near Field Communication (NFC) based interactions can be implemented by a device when it is placed near an NFC tag and receives an electromagnetic signal associated with the NFC tag. The device retrieves the identifier of the NFC tag from the electromagnetic signal and, based on the identifier, the device can generate a first command. Furthermore, the device can identify a qualifying event, such as a predetermined orientation of the device. The device then generates a second command in response to the identification of the qualifying event. Each of the first and second command can cause a change in settings of the device, switching an operating mode of the device, activating/deactivating an application, enabling/disabling a feature of an application, and sending an instruction to a remote electronic device.

A driver circuit includes a first inverter, a bias-control circuit, and a second inverter. The first inverter, which is connected between a first supply voltage and ground, receives an input data signal and generates an inverted version of the input data signal. The bias-control circuit, which is connected between a second supply voltage and the first inverter, receives the inverted version of the input data signal and a bias signal, and generates a level-shifted data signal based on the inverted version of the input data signal, the bias signal, and the second supply voltage. The bias-control circuit reduces a difference between voltage levels of the second supply voltage and the inverted version of the input data signal. The second inverter is connected between the second supply voltage and ground, and further connected to the bias-control circuit and first inverter and generates an output data signal.

Provided are a computer program product, system, and method for providing a mediation layer between a virtual network function manager and virtual network functions supporting different protocols. A first command is received in a first communication protocol to perform an operation at a target virtual network function component managing a virtual resource. A determination is made of a second command in a second communication protocol mapping to the first command to perform a function of the first command at the target virtual network function component. The second command is communicated, using the second communication protocol, to the target virtual network function component to perform an operation with respect to the virtual resource managed by the target virtual network function component.
