Abstract: A triggered restart mechanism for failure recovery in power over Ethernet (PoE). Powered devices (PDs) that fail can be remotely recycled by a power sourcing equipment (PSE). After detection of a failure of a PD, such as by the failure to receive a status message, a PSE can generate a reset signal (e.g., power cycle, reset pulse, etc.) on the port. This reset signal can cause the PD to perform a full power cycle or quick restart.

Abstract: A system, method and apparatus are described herein that allow a mix computers or other devices that are configured for communication in accordance with different network layer protocols, such as Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), to share a single physical connection to a WAN. To achieve this, a networking device such as a router resides between a plurality of local devices and the physical connection to the WAN and routes network layer packets between the local devices and the WAN. The networking device determines whether each local device is IPv4-capable or IPv6-capable. Based on this determination, the networking device selectively applies Network Address Translation (NAT) and optional firewall functionality to network traffic originating from or destined for the IPv4-capable devices, while bypassing such functionality for IPv6 network traffic originating from or destined for the IPv6-capable devices.

Abstract: High speed, low power all CMOS thermometer-to-binary demultiplexer. A received signal undergoes digital sampling (e.g., as within an ADC) to generate a signal that subsequently undergoes encoding (e.g., transformation from thermometer encoded data to binary encoded data) and de-multiplexing. Two separate de-multiplexing stages are employed when performing combined encoding and de-multiplexing. In addition, the individual DEMUXs of the two stages are clocked using a distributed clock generation architecture, such that, reset and time-interleaving is controlled on the ADC clock generator. The thermometer-to-binary encoders are placed very close to the input stage which facilitates very fast data rates while consuming relatively lower power.
