Abstract: A system and method for providing backup communications using Power over Ethernet (PoE) are disclosed. A backup communication system (BCS) is provided as part of a networked (TCP/IP) hospital communication system. The BCS is coupled to a power line used to provide power to a PoE switch. When TCP/IP communications are interrupted, the BCS receives patient call signals from patient room terminals over a secondary communication mode of the power line, and transmits those call signals to a nurses' station. The call signals can be generated by coupling a pulse-coded AC signal onto the PoE wires, or by sending voltage coded data in one direction and current-coded data in the other direction. Different signals or signal levels can be used to distinguish normal patient calls, patient emergency calls, and code calls. Thus, basic communications can be achieved when TCP/IP are unavailable. Other embodiments are disclosed and claimed.

Abstract: A process for transalkylation of polyalkylated aromatic components can include providing a transalkylation reaction zone containing a transalkylation catalyst. A feedstock can be introduced into an inlet of the transalkylation reaction zone and into contact with the transalkylation catalyst. The feedstock can include a polyalkylated aromatic component derived from an aromatic substrate. The aromatic substrate can be supplied to the transalkylation reaction zone. The transalkylation reaction zone can be operated at temperature and pressure conditions sufficient to cause disproportionation of the polyalkylated aromatic component to produce a disproportionation product having a reduced polyalkylated aromatic content and an enhanced monoalkylated aromatic content. The disproportionation product can be withdrawn from the transalkylation reaction zone. Amounts of nitrogen containing compounds in the aromatic substrate can be monitored in a range of from 15 to 35 wppm by dry colorimetry.
