    摘要: A power supply, includes: a hot node coupled to a hot wire of an AC source, and a ground node coupled to an earth ground, where a neutral wire of the source is not present; a storage component, coupled to a return node and in series with a current limiter, where the current limiter enables the storage component to charge to a voltage while limiting leakage current to a prescribed value; a low voltage power supply including a buck-boost regulator, coupled to the storage component and to a return node that provides a reference voltage, where the low voltage power supply receives the voltage and generates an output voltage on an output node that is referenced to the reference voltage; and a wireless transceiver that employs the output voltage to transmit and receive messages from one or more corresponding wireless devices.

    摘要: A multimode switch includes a line voltage switch, coupled to a line voltage and a device; a switch controller that directs the line voltage switch to provide line voltage to, and subsequently remove line voltage from, the device, and that receives first identifying information for the device, and that controls the device according to the first identifying information; and a ground leakage power supply, coupled to an AC hot line and to an earth ground, that generates a regulated voltage to power the switch controller without requiring connection to an AC neutral line, while limiting ground leakage current to the earth ground to a prescribed leakage value.

    摘要: A system for automated origination of capital includes a rate processor, a revenue forecaster, and an offer processor. The rate processor generates prices for capital product offers to subscribers of a point-of-sale (POS) subscription service, where the prices are generated by employing probability of default (PD) values that are derived from historical POS data corresponding to each of the subscribers. The revenue forecaster employs the historical POS data to predict future POS data for establishments corresponding to the each of the subscribers and employs the future POS data to generate predicted total revenues corresponding to the each of the subscribers over a payback period. The offer processor generates and transmits the capital product offers corresponding to the each of the subscribers, where the capital product offers comprise the payback period, the prices, and maximum dollar amounts that are a percentage of the predicted total revenues.

    摘要: A system that detects energy resource outages includes: resource monitors, each disposed within radio range of resource meters that transmit corresponding radio signals indicative of meter identifiers and current readings, where the resource monitors are configured to receive and decode the radio signals to obtain one or more of the meter identifiers and current readings, and where the each of the resource monitors transmits the one or more of the meter identifiers and current readings over the internet cloud; and a resource server, operatively coupled to the resource monitors via the internet cloud, configured to receive the one or more meter identifiers and current readings from the resource monitors, and configured to employ the current readings to detect an outage within a geographic area, and configured to send alerts to a resource provider that correspond to the outage.

    摘要: A method for transaction handoff includes: registering a payment instrument with a server, associating the payment instrument with ephemeral tokens, and storing a payment token that associates the ephemeral tokens with the payment instrument and a device identifier in a database record; via a device, receiving an ephemeral token from the server; via a point-of-sale (POS) terminal, scanning the ephemeral token, and transmitting ephemeral token via the internet cloud to the server; via the server, using the payment token to access the device identifier and transmitting a push notification; upon acceptance of the push notification, executing an application on the device and simultaneously displaying transaction details on both the device and POS terminal; receiving completion data that is entered via the device and transmitting the completion data to the server; and completing the transaction at the server and notifying the POS terminal and the device that the transaction is complete.
