International Classification:

G06F 9/46
G06F 15/16

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.

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:

H04M 1/64
H04M 3/42

US Classification:

379 671, 37920201

Abstract:

A method for recording a conference call session established between a client device and a server device, the conference call session being associated with time indicators including a current time indicator. The method includes storing in a memory conference call content from the conference call session along with associated time indicators, receiving an instruction through an interface of the client device during the conference call session, and outputting on the client device, in response to receiving the instruction, the conference call content from the memory from a time indicator prior to the current time indicator. The interface can include a pause option or a rewind option for controlling output of the conference call content during the conference call session.

International Classification:

G06Q 30/06

US Classification:

705 268

Abstract:

An apparatus and method for selective checkout of items in a shopping cart is disclosed herein. One or more items placed in a shopping cart may be selected for purchase without emptying the shopping cart of the items that a user does not wish to purchase at that point in time. The items remaining in the shopping cart after checkout are automatically retained for future use by the user.

Assignee:

Research In Motion Limited - Waterloo

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

Presented are systems and methods for distributing server-based services using a service development platform. The service development platform acquires server-based service data associated with a first server-based service, and parses the server-based service data. The service development platform catalogs the parsed server-based service data into a server-based service catalog that contains one or more server-based services different from the first server-based service. Additionally, the service development platform receives a request from a client device for the first server-based service indexed in the server-based service catalog, and provides the first server-based service to the client device.

Abstract:

An optical device includes a substrate, a first surface-relief grating including grooves and ridges formed on or in the substrate, a first overcoat layer in the grooves of the first surface-relief grating, and a first antireflective layer on the first overcoat layer. The ridges of the first surface-relief grating include high-refractive index, photoactive metal oxide nanoparticles and a material of the first overcoat layer in regions between the metal oxide nanoparticles, or the first overcoat layer includes the metal oxide nanoparticles and a material of the first antireflective layer in regions between the metal oxide nanoparticles. Methods of fabricating the optical device are also described.

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.
