Abstract: Systems, and programming for improved arrangement and administration of syndicated loans using computer networks. Each of a plurality of bookrunners is authorized to invite any number of other bookrunners, as well as any number of loan participants, or underwriters (i.e. investors or lenders), to participate in offering and administering a loan, typically by providing various forms of information describing the proposed loan, including the borrower, the proposed terms, and possibly any potential participants in making the loan. Invitees who accept such invitations may be associated with the inviting bookrunner, and upon being accepted as participants may be granted by the bookrunner access to various sets of communications, documents, and other information concerning the proposed loan.

Abstract: AC power supply circuitry comprising an AC power source is provided. The circuitry further comprises a semiconductor switching device in an AC power line between the power source and an output and a switch that switches the semiconductor switching device between a first state in which it transmits power from the source to the output and a second state in which it does not transmit power to the output. The circuitry further comprises a diplexer that couples communications data on to the power line. Communications data is coupled on to the power line only if said semiconductor device is in said first state.
