Abstract: A device, a method for determining relative positions of power consumers based on a high-frequency signal, and a computer-readable storage medium are provided. The device is applied to a distribution transformer supply zone. The device includes a resonance or signal generator and a direction detector, the resonance or signal generator is disposed in a user electricity meter, the direction detector is disposed on a power line, the resonance or signal generator is configured to transmit a high-frequency signal or generate resonance in response to the high-frequency signal; the direction detector is configured to monitor a voltage and a current of the high-frequency signal flowing into the user electricity meter, and determine, based on a phase difference between the voltage and the current, a relative position relationship of two adjacent user electricity meters on the power line.

Abstract: A calibration scale includes a scale body and at least two calibration pattern subsets arranged on the scale body along a first direction. The at least two calibration pattern subsets include a plurality of first calibration blocks arranged at spacings along the first direction and staggered along a second direction. Projections of the plurality of first calibration blocks in each calibration pattern subset along the first direction have a first overlapping area. Projections of at least two first overlapping areas along the first direction have a second overlapping area.

Abstract: A backup power circuit is provided. The backup power circuit includes a backup power branch array that includes N backup power branches that are coupled in parallel; and each backup power branch include a capacitor component and a unilateral conductive element, where the unilateral conductive element is configured to cut off a current path between capacitor components in the N backup power branches that are coupled in parallel, so that when some backup power branches are short-circuited, it can be ensured that backup power functions of other backup power branches are not affected, and backup power effects of the backup power branches are improved.

Abstract: The present invention relates to the field of communications and, in particular, to a method and a device for defending against bearer attack, and the method includes: stopping resource scheduling for a terminal, when a network device detects that a bearer transmission flow of the terminal is greater than or equal to a flow threshold value set by the network device. The present invention can defend the network device (including a base station) against attack from the terminal which would initiate the attack by utilizing high transmission performance under high network transmission requirements.

Abstract: Disclosed herein are mixtures of turmeric extract oils. One mixture of turmeric oils is the hexane soluble fraction obtained by dissolving turmeric powder in hexane to form a hexane mixture, filtering the hexane mixture and evaporating the hexane from the turmeric oil mixture. A more refined turmeric oil combination is the oil left after the turmeric oil mixture is dissolved in hexane, placed on a silica gel/hexane chromatography column, and eluted with hexane into fractions that were then evaporated, thereby leaving the refined turmeric oil combination. Also disclosed are methods for treating inflammation, arthritis and rheumatoid arthritis and a pharmaceutical dosage form of the refined turmeric oil combination.
