Stream-based data deduplication with peer node prediction
Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers. |

Small and seamless carrier detector
In a carrier detector, the simple latch is replaced with a pulse timer and reference control module which outputs logic high (H) when more than two consecutive toggled signals come within 1.5 baud periods and keeps logic high (H) until it misses a toggled signal for two baud periods.

Wire bond free wafer level LED
A wire-bond free semiconductor device with two electrodes both of which are accessible from the bottom side of the device. The device is fabricated with two electrodes that are electrically connected to the oppositely doped epitaxial layers, each of these electrodes having leads with bottom-side access points. This structure allows the device to be biased with an external voltage/current source, obviating the need for wire-bonds or other such connection mechanisms that must be formed at the packaging level. Thus, features that are traditionally added to the device at the packaging level (e.g., phosphor layers or encapsulants) may be included in the wafer level fabrication process. Additionally, the bottom-side electrodes are thick enough to provide primary structural support to the device, eliminating the need to leave the growth substrate as part of the finished device. |
