In an electrical power outlet device, a processor and a memory are configured to execute an application within the outlet device, which computes a pattern of usage of the outlet device. A set of sensors in the outlet device includes a first sensor that is usable to detect an event in an environment in which the outlet device is supplying power. The environment includes elements that are not participating in an electrical circuit that receives power from the outlet device and the event is usable by the application to alter the pattern of usage. An autonomous modification of an operation of the outlet device is performed in response to the pattern of usage, the event, or both. The operation changes a power supplying state of the outlet device without using an external switching apparatus or an external logic implemented outside the outlet device.

An electronic apparatus includes: a plurality of input ports to which a plurality of first external devices are connected; a converter; an output port to which a second external device is connected; and a processor that controls the converter to convert a plurality of input voltages of the plurality of first external devices connected to the plurality of input ports into an output voltage, identifies whether power is capable of being supplied by each of the input voltages, and controls the converter to output the converted output voltage to the second external device to the output port, based on whether the power is capable of being supplied.

A network of devices that include Workspace Fitness Devices, such as Smart Under-the-desk Bikes and Smart Desk Controllers embedded in Smart Sit-and-Stand Desks that connect or talk to one another, electronically identify individual users, track their activities, connect to a remote server database, and modify its records. Secondary devices such as smartphones, can connect to this network to remotely monitor and control the settings on the devices such as the desk's height or the required tension in the Smart Under-the-Desk Bike. The performance data captured by this network of devices can be shared to fitness tracking software or devices. By using our invention, we plan to motivate employees that sit behind the desk for numerous hours throughout the day to improve their health, productivity, and overall wellbeing.

A circuit comprises an output connector connectable to a load. A relay selectively connects the output connector to an AC power source. The relay is responsive to a disabling signal to disconnect the output connector from the AC power source. A sensor senses a level of power delivered to the load via the output connector. A detector emits a first fault signal when the sensed power level exceeds a fixed power limit. A latch maintains the first fault signal until it receives a rearm signal. A controller emits a second fault signal when the sensed power level exceeds a configurable power threshold, receives a user command to rearm the circuit, and in response to receiving the user command, emits the rearm signal and ceases the emission of the second fault signal. A logic combiner generates the disabling signal when it receives one of the first and second fault signals.

A system and method is disclosed for detecting a specific voltage phase, from a multiphase voltage source, and a specific outlet of an intelligent power strip, that is associated with a residual current flow. The method accomplishes this by using a system that employs a statistical time series analysis using a Pearson's correlation coefficient calculation to measure the linear dependence between the discretely sampled residual current waveform and each phase and outlet's discretely sampled current waveforms, in turn. A residual current as low as 1 mA can be accurately measured and its associated voltage phase source, as well as which outlet of an intelligent power strip it flows out of, can be reliably determined.

The present disclosure relates to a method and apparatus for providing power supply control of a power strip.

A method of preventing disjunctions in a power distribution unit having a plurality of output connectors is disclosed. A power level of each of the output connectors is sensed. It is detected that the power level of a given output connector exceeds a fixed power limit. In response to the detection, a delivery of power by the given output connector is stopped while maintaining a delivery of power by a remainder of the output connectors. Power delivery may be resumed in response to receiving a user command to rearm the given output connector. A power distribution unit adapted to prevent disjunctions is also disclosed.
