A method for data sorting in an information storage system and an information storage system are described. The oscillator includes a resistance element disposed in parallel to the negative resistance element. The wearable apparatus may also include at least one processing device configured to, in a first processing-mode, process representations of the plurality of images to determine a value of at least one capturing parameter for use in capturing at least one subsequent image, and in a second processing-mode, process the representations of the plurality of images to extract information. Fluid coupled to the valve device is a vaporizer which is in communication with an engine. The digital camera acquires pixel positions of the original image using an affine parameter, and acquires pixel positions of the image before distortion correction using a relational expression of distortion correction performed on the reduced image.
