Abstract: Systems, methods, and apparatuses described herein correspond to non-linear spring assemblies of a haptic engine. An enclosure and/or lid of a haptics engine may include a number of non-linear spring assemblies to dampen or reduce peak forces between internal components of the haptics engine and the enclosure and/or the lid. By dampening or reducing peak forces, damage to internal components of the haptic engine and/or an associated electronic device may be reduced or eliminated.

Abstract: A network device includes memory with permanent storage. A request for information is received from a user device. In response to determining that an erasure encoded version of the requested information is not stored in the memory of the network device, the requested information is requested to be transmitted from a storage external to the network device and partially received. In response to determining that an amount of the partially received requested information does not satisfy an erasure encoding threshold, it is determined whether the erasure encoding threshold can be satisfied within a time duration. If so, the partially received requested information is erasure encoded, stored in the permanent storage, and transmitted. If not, the requested information is requested to be retransmitted from the storage external to the network device.

Abstract: Embodiments of network devices for content distribution are described. In some embodiments, an edge network device integrates network coding for content distribution with erasure coding for data storage. Embodiments of methods of integrating network coding and erasure coding are also disclosed. In some embodiments, an edge network device can determine content distribution and storage for content based on one or more penalty functions that assess storage capacity, computational power, user demand, and/or network bandwidth for optimal resource usage. In some embodiments, an edge network device creates fragments of content and transmits a subset of the fragments for early distribution. In response to a user request for the content, the edge network device can transmit the remaining fragments to the user device for the user device to reconstruct the original content.

Abstract: Described herein are enhancements for deploying a Peripheral Component Interconnect Express (PCIe) switch in a computing enclosure. In one implementation, a PCIe switch is coupled to a plurality of hosts and at least one network interface via PCIe lanes.

Abstract: Systems and methods to improve content distribution by reducing computational demand, optimizing network usage, and/or providing protection for content are disclosed. In some embodiments, the requested content can be encoded using scalable video coding with erasure coding and/or bit-level chunks coding. Scalable video coding can be used to create one or more base layers and/or one or more enhancement layers for a requested content. Bit-level chunk coding and/or erasure coding can be used to create fragments of the one or more layers. In some embodiments, the end point device, the edge network device, and/or the data center can select a policy for encoding the requested content based on a security level for the user device, a security level for an edge network device, a security level for a data center, a demand for the requested content, or a computational complexity for reconstructing the requested content.

Abstract: A fastener comprises a shaft extending along a longitudinal axis, and a sleeve wrapped partially around the shaft. The sleeve comprises an inner surface adjacent the shaft, an outer surface, an upper extent, a lower extent, a first circumferential extent, a second circumferential extent, and a gap extending longitudinally from the upper extent to the lower extent and separating the first circumferential extent from the second circumferential extent. The sleeve has a first thickness adjacent the first circumferential extent that is less than a second thickness between the second circumferential extent and the first circumferential extent. A cross-sectional centroid of the shaft between the upper extent and the lower extent is in substantially the same location, with the sleeve in different first and second rotational positions.
