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:

G05B 19/042

Abstract:

A system for updating a device in a building management system (BMS). The system includes a third-party device and a device manager of a control network. The device manager updates the third-party device and includes a processing circuit that determines that the third-party device has been discovered on the control network. The processing circuit further populates a template with a set of received data from the third-party device and maps the third-party device with control network based on the populated template of received data. The processing circuit further configures the third-party device to operate in the control network, wherein configuring the third-party device comprises transforming a data exchange format of the third-party device.

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.

International Classification:

G01N 21/21
G01B 11/06

Abstract:

Various embodiments set forth techniques for characterizing films on optically clear substrates using ellipsometry. In some embodiments, a spectroscopic ellipsometer is configured to generate a light beam that has a relatively small spot size and is substantially absorbed by an optically clear substrate, thereby reducing or eliminating reflections from an interface between the substrate and air. Optical simulations can be performed to determine values for various parameters associated with the ellipsometer that minimize the reflections from the interface between the substrate and air and maximize reflections from an interface between a film and the substrate. In addition, graded films that include multiple layers can be analyzed using models of multiple layers.
