The present invention provides methods and apparatuses that utilize a portable apparatus to securely operate a host electronic device. The annotations are created by one or more annotation authors and are shared with one or more other users. Parameters may include light intensity, firing rate, duty cycle, other suitable parameters, or any combination thereof. A method of determining the relative severity of SIBO or a SIBO-caused condition in a human subject, in whom small intestinal bacterial overgrowth has been detected, is also disclosed. The base board of the base seat always keeps entirely contacting with the ground so that the frictional force against the ground is greater and the base seat can be stably placed on the ground. Thus, a buckle apparatus is provided which includes a detection mechanism that can reliably detect when the tongue plate has been inserted into the apparatus main body.
