Abstract: An adaptive biometric authentication system may include a user identity reference module that is configured to maintain user identification items stored in a secure memory. The system may include a passive data aggregator that is configured to receive and aggregate data items that are passively collected by a device that is in proximity to a user. The system may include a user identity confidence level generator that is configured to generate a user identity confidence level that indicates a confidence that the user in proximity to the device is the reference user based at least in part on a comparison between the passively collected data items and the user identification items, and to update the user identity confidence level as additional passively collected data items are received. The system may include an authentication module that facilitates user authentication based at least in part on the user identity confidence level.

Abstract: Power distribution circuitry to improve wireless power distribution and facilitate wireless power transfer (WPT) operations in a wireless communication device under a variety of operating conditions. In various exemplary embodiments of the disclosure, the power distribution circuitry operates to provide a wireless power (WP) supply voltage to wireless communication circuitry of the device in order enable a WPT connection procedure under certain low power conditions. Such conditions might include a power off mode, a sleep mode, and dead/low battery operating conditions wherein the available battery supply voltage is less than a threshold voltage required to enable device components. The power distribution circuitry may switch the supply voltage of the wireless communication circuitry to another available supply voltage source after the WPT connection procedure is completed and wireless power is being received by the wireless communication device.

Abstract: Aspects of the subject disclosure may include, for example, a power receiving unit having a wireless power receiver configured to receive a wireless power signal from a power transmitting unit. A rectifier includes a plurality of switching circuits configured to generate a rectified voltage from the wireless power signal, based on switch control signals that include a switch-on signal and a switch-off signal for corresponding ones of the plurality of switching circuits. A rectifier control circuit generates the switch control signals based on predicted switching delays. Other embodiments are disclosed.

Abstract: A system for hierarchical management of devices may include memory and a processor. The processor may configure first devices of a first network with device operating policies to perform operations based at least on attributes of the first devices, where the operating policies prevent device interference. The processor may discover a second network of second devices managed by a second management entity and may negotiate with the second management entity to determine a primary management entity for the networks. The processor may receive device operating policies and attributes of the second devices when the second management entity is not the primary management entity. The processor may provide an adjusted device operating policy for a second device to the second management entity when the second device causes interference with a first device, the adjusted second device operating policy being based at least on attributes of the second device.

Abstract: A proxy device for a network of devices may include memory, a device status module, a data intercept module, a network interface, and an emulation module. The memory may be configured to store an emulation policy for emulating a device in a network, where the policy includes a status criterion that indicates a status of the device for which the policy applies. The device status module may be configured to monitor the status of the device. The data intercept module may be configured to intercept action requests directed to the device. The network interface may be configured to forward the intercepted action requests to the device when the status of the device fails to satisfy the status criterion. The emulation module may be configured to emulate the device, and respond to the action request without accessing the device, when the status of the device satisfies the status criterion.

Abstract: Methods and systems for auto coexistence priority selection for a SCO link are disclosed. Aspects of one method may include a first Bluetooth device communicating with a collocated WLAN device via a coexistence method. The first Bluetooth device, prior to executing a non-SCO task, which may comprise tasks that do not involve SCO packet transfer, may communicate low priority via the coexistence method if a Bluetooth SCO link is present between the first Bluetooth device and a second Bluetooth device, and if a current task being handled by the first Bluetooth device is a high priority task. If a SCO link is not present between the first and second Bluetooth devices, and if the current non-SCO task is a high priority task, the first Bluetooth device may communicate high priority via the coexistence method prior to executing the non-SCO task.

Abstract: A user's request via a portable or handheld wireless communication device (HWCD) to process data may result in discovery of one or more networked resources capable of handling the processing. One or more communication routes may be established between one or more discovered network resources and one or more of the HWCD and a networked terminating device. The portable HWCD may be configured as a gateway. The user's identity may be determined and the user's personal networking preferences may be acquired. Based user's preferences, a route may be established between discovered networked resources and one or more of the HWCD and the networked terminating device. The user's identity may be authenticated. Data may undergo rate and/or format conversion. The data may be protected by secure operations. One or more of the HWCD and the networked terminating device may consume or render the requested data.
