Abstract: Embodiments of apparatus, computer-implemented methods, systems, and computer-readable media are described herein for wirelessly transferring communication roles between devices, using technology such as near field communications (“NFC”), optical communication (e.g., barcodes), BlueTooth and so forth. In various embodiments, a first device may transfer, from the first device to a second device using near field communication, data used by the first device to communicate with a third device, to cause the second device to initiate communication with the third device based on the data. Likewise, in various embodiments, a first device may receive, from a second device using NFC, data used by the second device to communicate with a third device, and to initiate communication with the third device based on the received data.

Abstract: A system for powering up a computer having a central processing unit (CPU), which CPU includes an operating system (OS), when the CPU is in an Sx state in which the (OS) is not powered up. There is a near field communication (NFC) detector for detecting an NFC signal, and an embedded controller physically separate from said CPU, the embedded controller responsive to the NFC signal and adapted to power up the CPU out of said Sx state.

Abstract: Apparatus, system, and method having a first counter to record a number of invalid authentication requests, a first timer to set a first time period based on a value of the first counter, and an authentication module associated with the first counter and the first timer to receive an initial authentication request that includes a username and when said username is invalid, the module is to invalidate any subsequent authentication requests under the username during the first time period regardless of whether the subsequent requests includes a valid username. The system further includes a communication medium. The method includes receiving an authentication request with new information in a first session, validating the new information, and caching the validated new information in the first session.
