Improved methods and devices are provided for detecting andor predicting the onset of an undesirable physiological event or neural state, such as an epileptic seizure, to facilitate rapid intervention with a treatment therapy such as neurostimulation or drug therapy. A storage device stores contents in each of a plurality of storage areas corresponding to a plurality of groups. An image with the highest evaluation value is selected, and when there are a plurality of images with the highest evaluation value, an image taken first is selected. A second semiconductor die is mounted to the second substrate and electrically connected to the second conductive layer. The soft pipe is stretchable in said direction relative to the bendable body in response to changes of pressure inside the soft pipe, which results in the bendable body and the soft pipe bending.
