A system and method that facilitates dynamic group formation for social interaction and / or real-time sharing of content with the group is provided. A group formation system includes a user interface component that facilitates a user's entry of information and display of information regarding group formation. For example, the user interface component can be employed, for example, with a mobile communication device such as a mobile phone, personal digital assistant (PDA), a smart phone, a small, web based mobile or a wireless application protocol (WAP) client, and / or a regular web client. The system can further include a group formation component that forms a group based, at least in part, upon information received from a user via the interface component. The group configuration component can further store information regarding groups (e.g., a name / identifier, member(s), event(s) and / or shared context associated with the group) in a group information data store. For example, the group configuration component can form a group based, at least in part, upon information stored in the group information data store (implicit group formation). The group information data store can, optionally, provide archival access to communications and / or shared content (e.g., through a mobile communications device and / or a PC-based web browser).

Techniques to support independent power control of multiple channels in CDMA systems (e.g., a W-CDMA system) that define a single power control feedback stream on the uplink, which is to be used for downlink power control. In one aspect, the single feedback stream is "time shared" among multiple channels requiring individual power control. Various time-sharing schemes may be used to implement multiple (substantially parallel) feedback substreams based on the single feedback stream, and different combination of feedback rates may also be achieved for the substreams. Each feedback substream may be assigned to, and used for power control of, a respective channel. In another aspect, multiple feedback substreams are implemented based on multiple fields in newly defined slot formats.

An application usage time limiter monitors certain pre-configured application programs when opened or otherwise executed on a computer (e.g. a PC). The application usage time limiter is itself a program running either as a front end to various selected programs for monitoring, or as a separate program running in a time-sharing operating system environment. Pre-configurable options in a usage limiter configuration file or other memory area are set to limit real time ranges that particular application programs on a particular computer can be started and run, and a limit to a length of time that a specific program (or category of programs-an be operated given a number of available credits for a current user. The user is given credits at a pre-configured rate per hour of usage of an application program designated in the usage limiter configuration file as being beneficial, and the user gives back (or looses) credits at a pre-configured rate per hour of usage for use of programs designated as non-beneficial. Preferably, continued usage of beneficial programs is detected, e.g., by keystrokes. Application programs selected for monitoring in the usage limiter configuration file can be identified on an application by application basis, as a specific category of applications identifiable when the particular application is started, or as being stored in a specific directory (e.g., folder in a Windows(TM) operating system). A credit-giving (i.e., beneficial program) must be run by a particular user to earn credits before a credit-taking (i.e., non-beneficial program) can be run by that user. Up front credits may be provided to a particular user in a user log.

The method and apparatus may also enable provision of the plan to the devices via a licensed band of a primary component carrier and detecting a medium of the unlicensed band prior to the expiration of the time period to determine whether the medium is available in order to decide whether to turn on transmissions to the unlicensed band after one of the planned off durations.

A novel and useful apparatus for and method of spur reduction using computation spreading with dithering in a digital phase locked loop (DPLL) architecture. A software based PLL incorporates a reconfigurable calculation unit (RCU) that is optimized and programmed to sequentially perform all the atomic operations of a PLL or any other desired task in a time sharing manner. An application specific instruction-set processor (ASIP) incorporating the RCU is adapted to spread the computation of the atomic operations out over a PLL reference clock period wherein each computation is performed at a much higher processor clock frequency than the PLL reference clock rate. This significantly reduces the per cycle current transient generated by the computations. The frequency content of the current transients is at the higher processor clock frequency which results in a significant reduction in spurs within sensitive portions of the output spectrum. Further reduction in spurs is achieved by dithering the duration of the software loop of atomic operations and / or by randomly shuffling one or more non-data dependent instructions within each iteration of the software loop.

In an aircraft galley, a power network distributes power from a source to electrical consuming devices (oven, water boiler, coffee machine, trash compactor, etc.). A control unit is connected to and can individually address each of the devices via a databus. The control unit compares the actual existing power consumption to a prescribed maximum value. If the actual consumption reaches the maximum value, the control unit calls up a power reduction procedure from a catalog in a database, and provides corresponding control signals to one or more of the devices to reduce the power consumption below the maximum value. The individual devices receive power in a time-sharing, power-sharing, or time-staggered manner. An intelligent distribution of available power resources avoids power overloads, and allows optimal utilization of all galley devices without limiting the normal catering process.

Downlink and uplink frequencies in a wireless access system are time-shared by adjacent sectors, but remain dedicated to downlink or uplink transmission and may utilize FDD-only bandwidth within the MMDS spectrum. TDD wireless access equipment need only be modified by introducing a frequency change at the normal TDD guard point, with respective downlink or uplink periods for adjacent sectors offset to form overlapping frames. Cyclo-stationary processing, block equalization, and burst timing coordination allow the boundary between downlink and uplink portions of both frames to be set dynamically, improving spectral efficiency. Fast frequency switching within an allotted physical slot enables synchronization of time-sharing the dedicated frequencies to be maintained among sectors and cells. Duplex spacing between downlink and uplink frequencies for a given sector and adjacent sectors, combined with in-depth filtering of received signals, prevents spurious out-of-band transmission signal strength from reaching an interference level.
