摘要： An LED and its fabrication method are disclosed. The LED includes: a sapphire substrate (200); an epitaxial layer (220), an active layer (230) and a capping layer (240) arranged on the sapphire substrate (200) in sequence; wherein a plurality of bifocal microlens structures (201) are formed on the surface of the sapphire substrate (200) close to the epitaxial layer (220). The bifocal microlens structures (201) can increase the light reflected by the sapphire substrate (200), raising the external quantum efficiency of the LED, thus increasing the light utilization rate of the LED. Furthermore, the bifocal microlens structures (201) can improve the lattice matching between the sapphire substrate (200) and other films, reducing the crystal defects in the film formed on the sapphire substrate (200) and increasing the internal quantum efficiency of the LED.

摘要： A switching fabric having cross points that process multiple stripes of serial data. Each cross point includes a plurality of port slices and ports. Each port includes a plurality of FIFOs, a FIFO read arbitrator, a multiplexer, a dispatcher, and an accumulator. In one embodiment, each cross point has eight ports and eight port slices. A method for processing a stripe of data at a cross point at one port slice includes storing data received from other port slices in a plurality of FIFOs and arbitrating the reading of the stored data. A step of writing data received from a port at the one port slice to an appropriate FIFO in a different port slice is also included. In one embodiment, a method for processing data in port slice based on wide cell encoding and an external flow control command is provided.

摘要： Customer journey prediction and resolution is accomplished via a predictive model in which each user is mapped onto all available user journey information corresponding to a specific business. The predictive model is analyzed to understand the characteristics, preferences, and lowest effort resolution for the user related to the services that are subscribed to by the user. The predictive model is analyzed to predict the service or collection of services for each user. Embodiments interact with, provide and receive information from, and react to and/or deliver action to the customer across channels and across services. All customer and system behavior, data, and action is tracked and coordinated and leveraged for continuous feedback and performance improvement.

摘要： A backplane interface adapter with error control and redundant fabric for a high-performance network switch. The error control may be provided by an administrative module that includes a level monitor, a stripe synchronization error detector, a flow controller, and a control character presence tracker. The redundant fabric transceiver of the backplane interface adapter improves the adapter's ability to properly and consistently receive narrow input cells carrying packets of data and output wide striped cells to a switching fabric.
