Methods and apparatus related to capturing and/or rendering images
Camera and/or lens calibration information is generated as part of a calibration process in video systems including 3-dimensional (3D) immersive content systems. The calibration information can be used to correct for distortions associated with the source camera and/or lens. A calibration profile can include information sufficient to allow the system to correct for camera and/or lens distortion/variation. This can be accomplished by capturing a calibration image of a physical 3D object corresponding to the simulated 3D environment, and creating the calibration profile by processing the calibration image. The calibration profile can then be used to project the source content directly into the 3D viewing space while also accounting for distortion/variation, and without first translating into an intermediate space (e.g., a rectilinear space) to account for lens distortion. |

Stream-based data deduplication using directed cyclic graphs to facilitate on-the-wire compression
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. |

Methods and circuits for improved reliability of power devices operating under repetitive thermal stress
Thermo-migration induced stress in power devices can be mitigated by deactivating a subset of power device components (e.g., transistors, etc.) when the power device experiences a high stress condition. Deactivating the subset of power device components serves to bifurcate the active area of the power switching device into smaller active regions, which advantageously changes the temperature gradients in the active area/regions. In some embodiments, a control circuit dynamically deactivates different subsets of power device components to shift the thermo-migration induced stress points to different portions of the active region over the lifetime of the power switching device. |

Precious-metal-alloy contacts
Contacts that may be highly corrosion resistant, may be readily manufactured, and may conserve precious materials. One example may provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer may be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact may be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based. |
