Abstract: A wireless device is disclosed. The wireless device includes a wireless communication module, a data storage module, and a controller for controlling the storage and/or retrieval of data from the data storage module. The wireless communication module communicates with each of a plurality of remote devices and the data storage module defines a first storage area and a second storage area. The controller controls the communication of data between the first storage area and the remote device, and the second storage area and the remote device dependent upon access rights associated with the remote device. The first storage area typically defines a public storage area with which data is exchanged in a relatively free manner, and the second storage area typically defines a private storage area with which data is exchanged in a relatively restricted manner.

Abstract: A technique for self-isolation of a network device that has been identified as potentially harmful. The network device may be isolated from the network except for an out-of-band communication channel that can be used for management purposes to restore or repair the device prior to the network connection being re-established.

Abstract: In one embodiment, a data processing system includes, but is not limited to, a processor, a memory coupled to the processor, and a universal serial bus (USB) controller coupled to the processor and the memory. The USB controller includes a local memory to cache at least one activity descriptor of at least a portion of a periodic schedule having multiple frames stored in the main memory. The USB controller defers to service an active USB device described by one of the activity descriptors until a corresponding frame is scheduled to be serviced subsequently. Other methods and apparatuses are also described.

Abstract: A method and apparatus for a user to interface with a mobile computing device is disclosed. In one embodiment, a method comprises sharing a Bluetooth communications module between a primary processor system and a secondary processor system.

Abstract: A reconfigurable zone plate lens is disclosed. Some embodiments may include a central annular element having a first a first circumference centered about a central axis. Embodiments may also include a plurality of concentric annular elements of increasing circumference centered about the central axis and the central annular element, where each annular element is positioned around an annular element having a smaller circumference. The annular elements of some embodiments may each be adapted to be in either an active or inactive state where the active and inactive annular elements form a plurality of alternating active rings and inactive rings. Each active ring may include one or more annular elements in an active state and each inactive ring may include one or more annular elements in an inactive state. Each annular element may include one or more liquid crystal display (LCD) elements or micromirrors. Other embodiments are disclosed and claimed.

Abstract: A method and apparatus is provided for identifying which one of a plurality of first devices, within a wireless communication range of a second device, the second device is to establish substantive communications with. The method includes sensing which particular first device is within a physical range of the second device, and establishing substantive communications with the particular first device.

Abstract: An embodiment of the present invention is a technique to dynamically swap processor cores. A first core has a first instruction set. The first core executes a program at a first performance level. The first core stops executing the program when a triggering event occurs. A second core has a second instruction set compatible with the first instruction set and has a second performance level different than the first performance level. The second core is in a power down state when the first core is executing the program. A circuit powers up the second core after the first core stops executing the program such that the second core continues executing the program at the second performance level.

Abstract: According to one aspect of the invention, a method and apparatus for polarizing electromagnetic radiation is provided. The electromagnetic radiation may be divided into first and second portions, substantially all of the first portion may be linearly polarized in a first direction and substantially all of the second portion may be linearly polarized in a second direction, the first direction being substantially orthogonal to the second direction. The linear polarization of at least one of the first and second portions may be changed such that substantially all of both of the first and second portions are linearly polarized in a third direction. At least one of the first and second portions may be redirected such that substantially all of both the first and second portions are propagating in a fourth direction.
