Abstract: Provided is a setting method for resilient checkpointing based on machine learning, which predicts a future power level in advance through a lightweight power level predictor and dynamically adjusts checkpoint intervals to accommodate a future energy input. During the operation of a power harvesting system, a resilient checkpointing mechanism assigns an appropriate checkpoint interval to a future power cycle to match a current harvesting power based on a state of a future harvesting power. Therefore, the power harvesting system with the resilient checkpointing mechanism can realize low checkpointing overhead and rollback punishment. The method involves a lightweight power level predictor based on a fully connected neural network and a resilient checkpoint setting mechanism based on power level prediction, which determines a checkpoint interval of a current cycle based on a predicted power level of a future power cycle.

Abstract: Provided is a super-resolution image sensor and a producing method thereof such that, on the basis of not changing the arrangement of the image sensitive unit array of the image sensor, by means of the existing micro-lens manufacture techniques, the imaging resolution can be increased by offsetting micro-lens rows in a micro-lens array that covers upon the image sensitive unit array. In some examples, a super-resolution image sensor comprises an image sensitive unit array having image sensitive unit rows aligned with one another, and a micro-lens array covering upon the image sensitive unit array. Relative to a reference micro-lens row in the micro-lens array, the other micro-lens rows are regularly offset. Each micro-lens unit in the reference micro-lens row is center aligned with a corresponding image sensitive unit in a reference image sensitive unit row.

Abstract: The present invention discloses a multimode CMOS image sensor and a control method thereof. The sensor comprises an independent control area group, a peripheral control circuit, a section mode setting module and a section mode configuration module. The method comprises dividing an independent control area group of the sensor into sections; setting a mode for each of the sections obtained; configuring a control mode of the peripheral control circuit for a corresponding section according to the mode set. By means of the present invention, when imaging in a push-broom mode, a regular sequence of images with fixed pixel difference can be produced at high frequency, and by performing pixel unmixing or integrating on the images obtained, the resolution and signal-to-noise ratio of the images can be effectively increased; because it is possible for some image unit area(s) of the sensor not to be selected as a scanning area, such design can bypass image units with quality issues when imaging by the hardware, which increases the reliability of the device; the characteristic of multiple times of imaging for the same target within very short time by multiple channels of the device can be utilized to realize moving target detection of optical camera imaging.
