  • Patent number: 11387672
    Abstract: Smart electricity monitors with unique identities placed at individual power outlets within a building communicate frequent power measurements to a service which determines, from this power usage data, which outlets are associated with occupied seats within the building. This occupancy information can be used to update an occupancy model for the building that is used to forecast the building's occupancy. Based on present occupancy, projected occupancy, and other data, in some instances, the building's thermostats can be controlled and unoccupied seats can be assigned dynamically.

  • Patent number: 11258298
    Abstract: Reliability of devices such as lighting fixtures, is improved by replacing an inductor based voltage inverter to power the device with a switching constant current PWM controller. Avoiding use of an inductor and matching capacitor is made possible by a high voltage power input that exceeds the voltage requirements of the device. The power is pulse width modulated with a current feedback to control duty cycle, and thus average device current.

  • Patent number: 11204376
    Abstract: A DSP-based electrical energy metering device is provided. After determining a current application mode, a DSP controller compares an execution rate of each computing task with a corresponding preset comparison value, and outputs a first condition value to a condition general register based on a comparison result, so as to control an execution rate of each computing task in the DSP controller. A jump condition controller outputs a second condition value corresponding to the current application mode to the condition general register based on a change in the execution rate of each computing task compared with an execution rate of the computing task in a previous application mode, so that all computing tasks are executed. An adaptive word length controller adjusts an effective bit width of the electrical signal read by a data general register from a data memory at execution rates of different computing tasks.

  • Patent number: 11181407
    Abstract: Techniques for the design and operation of an efficient battery-powered meter are described herein. A metrology unit of the meter may be at least partially located in the gas flow of a pipe, and measures gas flow rate data according to a static flow sensor. The metrology unit calculates raw gas-volume data using at least the flow rate data as input. The metrology unit measures gas temperature to produce gas temperature data, and adjusts the raw gas-volume data, based at least in part on the gas temperature data, to produce corrected gas-volume data. The metrology unit accumulates the corrected gas-volume data over multiple minutes, hours or even days, and then sends the accumulated corrected gas-volume data to an index unit of the meter. By accumulating the data over time, fewer data transmissions are required. The index unit may send the accumulated the accumulated corrected gas-volume data to a utility server.
