  • Patent number: 10552925
    Abstract: Disclosed are systems and methods for monitoring and controlling the distribution of electricity. The power distribution platform includes an intelligent device that controls power delivery to a singular or plurality of end users. The device controls the times during which energy is delivered, and limits the electrical current available on a per socket basis. By limiting current draw, system operators can ensure that only high value appliances (LED lights, phone charging etc.) are powered. Local intermediaries buy credit in bulk from a power system operator, then sell it to users via a portable digital storage medium and mobile device in increments of days, weeks or months. Once loaded with credit, a user's power program is allowed to continue running for the specified duration. Further aspects of the embodiment include; usage data logging to cloud server, power theft detection and methods of synchronizing internal clocks of each intelligent device.

  • Patent number: 10425056
    Abstract: An EMI filter network may be used to provide interference filtering for multiple loads (referred to collectively as a dynamic load). In one aspect, the EMI filter network includes electrical switches that establish different configurations or arrangements of passive circuit elements (e.g., inductors and capacitors) where each configuration generates a different filter value. The EMI filter network may be communicatively coupled to a controller which changes the configuration of the EMI filter network using the switches in response to the dynamic load changing operational states. For example, each configuration of the EMI filter network may correspond to one of the operational states of the dynamic load. Thus, as the operational state of the dynamic load changes—e.g., different motors become operational—the controller alters the configuration of the EMI filter network to provide a filter value that corresponds to the current operational state of the dynamic load.

    Abstract: A method of operating an electrical feeder permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.

    Abstract: A communication system includes a sensor apparatus transmitting a sensor signal including detection information of a detection target as a digital signal and a microcomputer receiving the sensor signal through a signal line and performing a control operation at a predetermined operation cycle based on the sensor signal that is received. The microcomputer transmits, to the sensor apparatus, a synchronization signal which is synchronized with the predetermined operation cycle of the microcomputer. The sensor apparatus transmits the sensor signal at a predetermined constant cycle except when the synchronization signal transmitted by the microcomputer is received. The sensor apparatus changes a transmission timing of the sensor signal corresponding to the synchronization signal when the synchronization signal transmitted by the microcomputer is received.

  • Patent number: 9878736
    Abstract: A communication system includes at least one sensor apparatus including at least one sensing element and a transmission circuit, and a microcomputer including a reception circuit and a differential calculator. The sensing element detects a sensor value indicating a physical quantity of a detection target, and the transmission circuit transmits, as a digital signal, a sensor signal including information indicative of the sensor value at a predetermined transmission cycle. The reception circuit receives the sensor signal through a signal line and updates last time sensor value with present time sensor value. The differential calculator calculates, at a predetermined calculation cycle, a time differential value by performing a time differential calculation to the updated using time information provided separate from the sensor value.
