  • Patent number: 12348024
    Abstract: A circuit interrupting device including a line terminal, a wideband current sensor configured to measure a current flowing through the line terminal, a zero cross detection circuit configured to measure a voltage and frequency of the line terminal, and a microcontroller including an electronic processor. The microcontroller is configured to apply a digital filter to a line current measurement signal received from the wideband current sensor and estimate spectral density of the filtered line current measurement signal. The microcontroller is further configured to calculate an arcing characteristic based on the spectral density, determine whether an arc fault is present within the circuit interrupting device based on a comparison of the arcing characteristic to one or more thresholds, and activate an interrupting device when an arc fault is present.

  • Patent number: 11687291
    Abstract: Methods, systems, and devices for memory operations are described. A first set of commands may be received for accessing a memory device. The first set of commands may include non-consecutive logical addresses that correspond to consecutively indexed physical addresses. A determination that the non-consecutive logical addresses correspond to consecutively indexed physical addresses may be determined based on a first mapping stored in a volatile memory. A second mapping may be transferred to the volatile memory based on the determination. The second mapping may include an indication of whether information stored at a set of physical address is valid. A second set of commands including non-consecutive logical addresses may be received for accessing the memory device. Data for the second set of commands that include the non-consecutive logical addresses may be retrieved from the memory device using the second mapping.

  • Patent number: 9566451
    Abstract: A method for irradiation treatment planning for a target volume to be irradiated includes specifying a plurality of data sets. The target volume to be irradiated is depicted in each data set of the plurality of data sets. The data sets differ in that the target volume has another position and/or shape. A data set is selected from the plurality of the data sets and other data sets are registered to the selected data set. The method includes forming an amalgamation of the depicted target volumes using the registrations of the other data sets to the selected data set, and determining an area at risk in the selected data set. The method includes modifying the amalgamation of the target volumes such that the area at risk is excluded from the amalgamation of the depicted target volumes. An irradiation treatment plan is calculated using the modified amalgamation of the target volumes.
