Abstract: A system and method for continual cable thermal monitoring using cable characteristic considerations in Power over Ethernet (PoE) applications. Cable heating in PoE applications is detected through changes in electrical characteristics of the cable itself. By periodically monitoring the electrical characteristics such as insertion loss or cross talk of the cable, it can be determined whether the cable has exceeded certain thermal operating thresholds.

Abstract: A system and method for using a physical layer device to locate a thermal signature in a cable plant for diagnostic, enhanced, and higher power applications. Cable heating in specific sections of a network cable is detected through an automatic identification of a thermal signature in electrical measurements of a network cable. The correlation of the thermal signature to a specific section of the network cable enables network personnel to locate hot spots in the network cable with ease.

Abstract: A system and method for using an Ethernet physical layer device to identify cabling topologies. A power sourcing equipment (PSE) can power independent powered devices (PDs) using two sets of wire pairs in a single four-pair cable. Higher power PSEs can power a single PD using all four wire pairs in the cable. Conventional power over Ethernet (PoE) analog techniques (i.e., voltage, current, etc.) have a difficult time distinguishing where the wire pairs are going from the PSE. By using information (e.g., negotiated speed, link energy, distance diagnostic, etc.) generated by the physical layer device (PHY) subsystem, the PoE system can determine whether the two sets of wire pairs in a cable are powering a single PD or two independent PDs.

Abstract: A system and method for using a link energy signal in physical layer devices (PHYs) having a silent channel/interface in energy efficient Ethernet (EEE). LPI modes in EEE suffer deficiencies in cable unplug detection due to the latency in refresh cycles. LPI modes in EEE also suffer from potential frequency drift, which leads to high bit error rate (BER) when coming out of LPI mode. A link energy signal transmitted during LPI modes enables real-time detection of cable unplug and the frequency lock to be maintained.

Abstract: An interleaving operation can scramble (permute) a data stream, or each dimension (set of symbols (a, b, c, . . . )) in a data stream, immediately following FEC encoding or dimension multiplexing of the data stream. Bursts of errors might be combined with the permuted data before, during, or after transmission. A de-interleaver reorders the received symbols and, in the process, spreads (separates) the bursts of errors. Also, using the multi-dimensional interleaving and de-interleaving can balance SNR on each channel. Spreading the errors and/or balancing SNR can keep bursts from overwhelming the FEC decoder or an FEC decoder in any one channel. In one example, interleaving and de-interleaving can be used to scramble data over Ethernet twisted wire pairs. In another example, interleaving and de-interleaving can be used to scramble data or information broadcast via wireless telecommunications channels (e.g., radio frequency channels, multi-antenna channels, etc).

Abstract: Aspects of a method and system for an extended range Ethernet line code are provided. A local PHY may enable converting Ethernet media independent interface (MII) data from a 4-bit packet stream to a 3-bit packet stream. The 3-bit packet stream may be mapped to first and second ternary bits streams, for example, for communication to a remote PHY utilizing PAM-3 over one or more twisted-pair wires. The 3-bit packet stream may be scrambled and/or aligned before mapping. When a single twisted-pair wire is available, the local PHY may multiplex the ternary bits streams into a single stream. Start-stream delimiters (SSD) may be inserted before the ternary bits streams and end-stream delimiters may be inserted after the ternary bits streams. Idle signals may be inserted after the ESDs and before the start of the next frame of MII data.

Abstract: Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.

Abstract: Certain aspects for the start-up procedure of transceivers supporting higher data rates over twisted-pair copper cabling are provided for 10 Gbit/sec Ethernet links (10GBASE-T). During a PMA (physical medium attachment) training period of the start-up procedure, long PMA training frames are exchanged periodically between link partners. A significant portion of each PMA training frame consists of known pseudo random sequences simultaneously transmitted over four wire pairs. PMA training frames include an InfoField for exchanging parameters and control information between link partners. For example, the InfoField's payload comprises fields for indicating current transmit power backoff (PBO), next PBO, requested PBO, transition count, control information, and for communicating precoder coefficients. Information in InfoFields is repeated and is not necessary that a link partner decodes every InfoField. For example, by occasionally reading the transition count, a link partner can determine when a change in transmit PBO and/or a state transition is to occur.

Abstract: The present invention relates to a system for processing a lipophilic fluid, more particularly to a system for processing a lipophilic fluid utilized in a fabric treating process, even more particularly to a system for processing a lipophilic fluid such that contaminants such as water, surfactants, water, body/food oils, fatty acids, and dyes can be removed from the lipophilic fluid. In other words, the present invention relates to the “cleaning up” of or purification of a lipophilic fluid such that it can be re-used in a lipophilic fluid system.
