A system and method for combining a remote audio source with an animatronically controlled puppet includes the steps of entering an audio file on a user client by a person where the audio file is a statement spoken by the person. The audio file is sent to a secondary client that is remote to the user client. The secondary client has a puppet controlled by animatronics. The audio file is received by an audio circuit board that converts the audio file into movement parameters. The movement parameters are sent to at least one servomechanism mounted in the puppet to actuate the animatronics in synchronicity with the audio file. Movement of the puppet is video recorded to define a video file. The audio and video files are combined to define a final video production viewable by the person.

Systems and methods are provided for determining appliance service requirements including: receiving an electrical signal indicative of an electrical load of an appliance over a period of time; determining an activity performed by the appliance by comparing the received electrical signal to an electrical signature of the appliance performing the activity; and responsively to determining the activity, determining a required service for the appliance.

A load estimation device measures a voltage and a current supplied to a load connected to a portable power-supply, obtains a feature amount of the load from the voltage and the current. The device obtains a stored feature amount of each of loads, and related load information indicating a plurality of loads which are used in association with each other. The device estimates a load connected to the power-supply on the basis of the obtained feature amount and a stored feature amount, and predicts a load which is not connected to the power-supply and which is a load related to the estimated load on the basis of the related load information.

The present invention provides an information providing apparatus including a determining unit configured to determine an added value to be provided to a user of a portable electric power supply device including a storage battery that stores electric power to be supplied to electrical equipment detachably connected, wherein in a case where a kind of the electrical equipment is a specified kind of electrical equipment, the determining unit determines the added value to be provided to the user in such a manner that the added value to be provided to the user is higher than an added value in a case where the kind of the electrical equipment is not the specified kind of electrical equipment.

A power-supply measures a voltage and a current supplied to a load, obtains a feature amount of the load from the voltage and the current, estimates what a load connected with the power-supply is, based on the feature amount, determines, if the load has high and low power consumption states, whether or not the load has shifted from the high power consumption state to the low power consumption state, activates the engine and supplies the power generated by a generator to the load in a case where an operation state of the load is the high power consumption state, and stops the engine and supplies the power stored in a battery to the load in a case where the state of the load has shifted from the high power consumption state to the low power consumption state.

A management device is connected to an AC power line provided with a plurality of connection ports, each of which can be connected to an electric device including a power storage unit. The management device includes a measurement unit configured to measure an electric signal on the AC power line, a determination unit configured to determine a type of the electric device connected to the AC power line via a connection port in the plurality of connection ports based on a measurement result of the measurement unit, and a first prediction unit configured to predict an amount of power supply on the AC power line due to discharge of the power storage unit based on a determination result of the determination unit.

Methods, Systems, and Computer program products can use grid telemetry to generate a fingerprint. One of these methods includes generating a first grid telemetry fingerprint based on characteristics of an electrical grid. The method also includes verifying a transaction based on the first grid telemetry fingerprint and a second grid telemetry fingerprint associated with the transaction.

Provided is a power supply device in which the reliability of a voltage output is improved, and also provided is a system comprising the power supply device and an electric tool.
