Abstract: Systems and methods provide power quality devices that include a communication interface to establish communications with the computer.

Abstract: Methods and apparatus are disclosed for effecting transfers using an electronic representation of a commodity, such as money. The commodity is represented by a value note issued by a bank or other authority, and which includes: first information representative of public key information for a bearer; second information representative of a commodity represented by the value note; and third information representative of an issuer's signature which is verifiable from information including the first information, the second information and public key information for the issuer. Digital endorsement signatures are used to redeem one or more value notes for one or more others, and to authenticate information in the value notes to prevent alteration. Redemption instructions permit, for example, transfer of value note money to another party, encashing of value note money, consolation of individual value notes, and generation of short term guaranteed value notes.

Abstract: Methods for making real-time automated security trades are presented, the methods including: receiving historical market data related to a selected security; receiving affective data related to the selected security; performing an analysis on the historical market data and the affective data to produce a set of causally related input parameters, the set of causally related input parameters configured to provide a basis for determining whether to trade the selected security; receiving current market data related to the selected security; applying the current market data to the set of causally related input parameters; and automatically trading the selected security based on the applying. In some embodiments, methods further include: incorporating the current market data with the historical market data; and returning to the performing the analysis.

Abstract: A power filter circuit for protecting electronic equipment from electromagnetic interference introduced by a supply system circuit includes a fault condition sensing circuit capable of detecting whether the supply system circuit is properly wired. The sensing circuit controls switching circuits in accordance with the determination of whether the supply system is properly wired. The sensing circuit activates a first switching circuit to form a short circuit between the neutral and ground conductors of the power filter circuit when it is determined that the supply system circuit is properly wired. If any wiring fault conditions, including a reverse polarity wiring, is detected by the sensing circuit, the first switch is not activated and the short circuit is not formed between the neutral and ground conductors.

Abstract: A power filter circuit for protecting electronic equipment from electromagnetic interference introduced by a supply system circuit includes a fault/condition sensing circuit capable of detecting whether the supply system circuit is properly wired. The sensing circuit controls switching circuits in accordance with the determination of whether the supply system is properly wired. The sensing circuit activates a first switching circuit to form a short circuit between the neutral and ground conductors of the power filter circuit when it is determined that the supply system circuit is properly wired.
