摘要： A method includes receiving a first frame at a wireless access node, the first frame being received through a first communication network and having a source address; applying a function (e.g., a hash function) to the source address to derive a destination address; encapsulating the first frame in a second frame that includes the destination address and a source address identifying the wireless access node; and sending the second frame to a second communication network for receipt by a destination node having the destination address. The destination node is an access controller that maintains state for a station that sends the first frame. The first communication network may be an IEEE 802.11 network, and the second communication network may be an IEEE 802.3 network. The address of the access controller is one of potentially many virtual MAC addresses associated with the access controller that enables an N:M relationship between a particular access node and a plurality of access controllers that may be clustered, and a N:1 relationship between a Station and a virtual access controller.

摘要： A Talbot-illuminated imaging system for focal plane tuning, the device comprising a Talbot element, a tunable illumination source, a scanning mechanism, a light detector, and a processor. The element generate san array of focused light spots at a focal plane. The tunable illumination source shifts the focal plane to a plane of interest by adjusting a wavelength of light incident the Talbot element. The scanning mechanism scans an object across an array of focused light spots in a scanning direction. The light detector determines time-varying light data associated with the array of focused light spots as the object scans across the array of light spots. The processor constructs an image of the object based on the time-varying data.

摘要： A method for receiving and storing a packet of symbols. The method decodes the packet of symbols using a first decoding algorithm, and if the first decoding algorithm fails to correctly decode the packet of symbols, then the method decodes the packet of symbols using a second decoding algorithm. If the second decoding algorithm fails to decode the packet of symbols, then a third decoding algorithm is used. The third decoding algorithm can be sub-packet decoding, where a first sub-packet is part of the packet of symbols. If the first sub-packet is decoded successfully, then the method generates a channel estimate using the properly decoded information, and then uses that channel estimate to decode a subsequent sub-packet using the channel estimate, where the second sub-packet is a set of symbols that are a portion of the packet of symbols.

摘要： Predictive, multi-layer caching architectures may be used to predict which elements a user is most likely to navigate to within a collection of elements associated with a predefined layout and, in response, to increase the accessibility of these elements to a client device of the user. For instance, the techniques may utilize a predictive, multi-layer caching architecture for storing these predicted elements to decrease the latency to render these images if the user navigates within the collection of elements in the predicted manner. The collection of elements may comprise images (e.g., a 3D model, a map, etc.), video files, audio files, text files, or any other type of file that is consumable on a client device.
