Abstract: A method of determining ripeness of a growing mushroom involves obtaining a sequence of images of a growing mushroom over a period of time and, from the sequence of images, measuring one or more features of the growing mushroom to obtain temporal measurements for the one or more features. The temporal measurements indicate rates at which the one or more features are changing. The temporal measurements are compared to pre-determined ripeness functions to determine the ripeness of the mushroom. The mushroom is picked if the comparison indicates that the mushroom is ready to be harvested.

Abstract: Disclosed herein are locking devices for securing a motorcycle by holding or clamping a brake lever toward the throttle such that operation of the motorcycle is impaired. Disclosed locking devices include a first rigid arm with a female locking mechanism at one end and a second rigid arm pivotably coupled to the opposite end and having an male engagement portion with a plurality of notches that is insertable into and lockable with the female locking mechanism. The device has an open position wherein the first and second arms are pivoted away from each other such that device is positionable around a throttle and a brake lever of a motorcycle. The locking device also has a closed position wherein the engagement portion of the second arm is inserted into the female locking mechanism such that the device holds the brake lever toward the throttle such that a brake of the motorcycle is engaged and the motorcycle is restricted from rolling. A motion sensor system can also be included.
