  • Patent number: 11398161
    Abstract: Computer-implemented systems and methods are described herein for detecting unusually frequent exactly matching and nearly matching test responses. A plurality of test responses for each of a plurality of test takers is received. Evidence of a circulated key from the plurality of test responses is identified by detecting two or more test takers with exactly matching test responses for a plurality of questions. The strength of the evidence of the circulated key is analyzed by determining the probability that the two or more test takers would produce exactly matching test responses, wherein the strength of the evidence is inversely related to the probability. Test takers with nearly matching test responses to the circulated key are then identified. All test takers with exactly matching and nearly matching test responses are tagged for further investigation.

    Abstract: A power supply circuit and a power distribution method thereof are provided. The power supply circuit includes a power input switch block, a power supply measurement block, a power supply conversion block and a power supply control block. The power input switch block provides a first power supply voltage to a load circuit based on an external power supply voltage from an adapter. The power supply measurement block measures a current of the first power supply voltage. The power supply conversion block is coupled to the battery module to provide a second power supply voltage to the load circuit. When a battery temperature of the battery module is higher than a critical temperature and a battery power of the battery module is higher than or equal to a critical power, the power supply control block limits the second power supply voltage provided to the load circuit.
