US Classification:

718104, 719321, 709230, 370912, 370913

Abstract:

Various embodiments provide a two-way interface between a URC driver (URCD) and various Protocol Adaption Layer (PAL) drivers. The two-way interface can enable bandwidth to be shared and managed among multiple different PALs. The two-way interface can also be used to implement common radio functionality such as beaconing, channel selection, and address conflict resolution. In at least some embodiments, the two-way interface can be utilized for power management to place PALs in lower power states to conserve power and to support remote wake-up functionality. Further, at least some embodiments can enable vendor-specific PALs to interact with vendor-specific hardware.

G06F 3/048

US Classification:

707724, 715769

Abstract:

An interactive visual interface for organizing, locating, searching, and monitoring collections of digital information, designed to harness human spatial memory for organizing and retrieving digital information. In one example, an information map organizes digital information within a two-dimensional space with rapid visual feedback and information access. The organization may be algorithmically computed and user-modified. An interface that supports persistent state information whereby search nodes and document references are spatially fixed so that users may harness their spatial memory to organize and find information quickly.

International Classification:

G06F 1/00

US Classification:

713323, 713300

Abstract:

Various embodiments enable a host controller, through its Protocol Adaption Layer (PAL) driver, to efficiently manage power consumption by employing “sleep mode” and “active mode” power settings. In some embodiments, the PAL driver may employ sleep mode settings to transition the host controller from an idle state to an energy conserving sleep state. In further embodiments, the PAL driver may use active mode settings to govern communications between the host controller and various devices, such as WUSB devices and others, thereby conserving power.

International Classification:

G02B 5/18

Abstract:

A multilayer architecture includes an amorphous optical layer, a crystalline optical layer overlying the amorphous optical layer, and a barrier layer located between the amorphous optical layer and the crystalline optical layer. The barrier layer may be configured to mediate the structure of the later-formed amorphous optical layer. For instance, a low absorption barrier layer may be formed over the crystalline optical layer within the multilayer architecture and accordingly inhibit crystallization within a subsequently formed optical layer, thus providing phase separation between the neighboring optical layers and a desired refractive index gradient within the multilayer architecture without adversely affecting the optical path length therethrough. Such a multilayer structure may be configured as a light retention layer, antireflective coating, bandpass filter, etc.
