Abstract: A mobile computing device that dynamically and automatically manages all network adapters on the device to obtain the best and most effective balance of network connectivity and power consumption without requiring operator or user application intervention. Performance is increased by lowering power consumption (longer battery life) and decreasing transaction latencies, providing a device that has flexibility and ease of use. According to one aspect is a system that includes a data analysis component that monitors parameters associated with a device and a mobility policy manager component that provides balance of network connectivity and power consumption based at least in part upon the monitored stimuli.

Abstract: A computing arrangement may include a first radio transceiver operating in accordance with a first communication protocol using a frequency band and a second radio transceiver operating in accordance with a second communication protocol using the frequency band. An access point operates in accordance with the first communication protocol and transmits a communication signal that has a frame including a first time interval indicative of when communications using the first communication protocol via the frequency band are permitted to the computing arrangement. The computing arrangement determines if the frame includes a second time interval, which is indicative of and is reserved for exclusive communications in accordance with the second communication protocol. If the second time interval is absent from the frame, the computing arrangement inserts the second time interval into the frame. The computing arrangement communicates with a further device only during the second time interval.

Abstract: According to an embodiment is a system that selectively permits or denies access to a restricted environment. Access can be based at least in part on the status of wireless transmitters of a mobile device, the status is one of active or inactive wireless communication. The system can automatically inactivate or disable a transmitter through a wireless command and thereafter permit access to the restricted environment. The mobile device can communicate wirelessly through one of a wireless local-area networks (WLAN), wireless wide-area network (WWAN), wireless personal-area network (WPAN).

Abstract: Described is an arrangement including a controlling arrangement, a wireless transceiver and a processor. The wireless transceiver communicates with a wireless device utilizing radio frequency signals at a transmitting power level. The processor collects network performance data (“NPD”) which is indicative of communication with the wireless device. The NPD includes at least one characteristic of the signals. The controlling arrangement adjusts the transmitting power level for the transmission of further radio frequency signals as a function of the NPD and previously collected NPD.

Abstract: System(s) and method(s) are provided that utilize external resources and protect the integrity of data within a mobile communication device and data communicated with the mobile communication device. The device includes an extrinsic data analysis component that receives information about both an external environment and an internal state. The device also includes an adaptive policy manager (APM) component. The APM component is adapted to analyze and prioritize policies based upon received input from external resources, stimuli, threats and/or parameters. The method of protecting data integrity is performed automatically and autonomously with minimal user intervention and awareness. The APM component includes a profile component, a policy modification component, a rules component, an authentication component, and an access control component.

Abstract: A system and/or method that enables a user to manage credential information for approving communications with various network and/or server components. A portable device is provided that facilitates management of a user credential that can be used to connect to a network (e.g., wireless, wired).

Abstract: The present invention manages power for state machines. The system and methods selectively apply, remove and/or reduce power to portions of the state machine, based on power management schemes, intelligence, a user, an application, etc. Such novel systems and methods provide for sustaining a CPU and/or a network radio in an “on” state, while lowering and/or removing power to other portions of the state machine to reduce power consumption. The foregoing enables a wireless mobile terminal to maintain network connectivity and be able to wake to service events such as a link status change, a network keep alive, a proxy-ARP packets, a re-authentication packets, etc. Such power management can execute in the background and return the wireless mobile terminal to a “run” state via invocation from a wake source such as a power control, a key, a trigger, a touch screen, a wake up timer, a wake-on-LAN, etc.
