Abstract: Methods and apparatus for enhanced power delivery between devices. In one embodiment, the power delivery is enhanced relative to legacy capabilities, and a source device negotiates with a sink device to establish a high-voltage (HV) power contract. In one variant, such HV operation enables power delivery greater than the legacy USB-C standard maximum of 20 V and 100 W. In one implementation, the source, sink, and/or source and sink collectively ensure that multiple criteria relating to power delivery are met for the interface (i.e., source, the sink, and the interposed cable or power delivery medium). Multiple conditions, including enclosure construction compliance and device capabilities, must be cleared to ensure safety while operating beyond standard maximums. If the criteria are met, HV validation is complete, and the source may offer HV operation to the sink to establish the HV contract. Additional fail-safe mechanisms enable the HV contract to discontinue upon triggering.

Abstract: The disclosed embodiments provide a system that transfers data from a storage device to a host. The system includes a communication mechanism that receives a request to read a set of blocks from the host. Next, upon reading each block from the set of blocks from the storage device, the communication mechanism transfers the block over an interface with the host. The system also includes an error-detection apparatus that performs error detection on the block upon reading the block, and an error-correction apparatus that performs error correction on the block if an error is detected in the block. The communication mechanism may then retransfer the block to the host after the error is removed from the block.
