The invention is a bug catching apparatus for catching and disposing of bugs. The following communications are provided: communication from a BREW application on a first mobile station to a BREW application on a second mobile station, communication from a BREW application on a mobile station to an application server or website, and communication from an application server or website to a BREW application on a mobile station. A cycle number indicating the current state of a linear feedback shift register and a stutter number indicating whether an output of the linear feedback shift register is dropped are both transmitted to a remote station along with the encrypted data stream. The cover includes a protrusion surface with protrusions extending into the first trough and the second trough. The varying structural characteristics is achieved by each individual structure of the succession being formed such that it allows light within a different angle interval with respect to the array to be sensed.
