Abstract: An airbox for an air intake system of an engine includes an air inlet for receiving air into the airbox, an air outlet for discharging air from the airbox, and an airbox body defining first and second expansion chambers fluidly connected to one another. The airbox body has a dividing wall separating the first expansion chamber from the second expansion chamber, the dividing wall defining a wall opening fluidly connecting the first and second expansion chambers. An interchangeable flute is removably connected to the airbox body. The interchangeable flute is at least partly disposed in the second expansion chamber and positioned to guide air flowing into the air inlet into the second expansion chamber. The interchangeable flute is removable such that a replacement flute can be installed in its place to selectively modify a noise output of the airbox. Other aspects are also contemplated.

Abstract: Method for synchronizing a slave database to a master database comprising the steps of: receiving a notification of a change in the master database and applying the notified change to the slave database wherein data of each of the slave and the master databases are organized as a First In First Out, FIFO, list containing a plurality of entries ordered according to their entry order in said database the most recent entry (ES4, EM4) being located at the end of the list whereas the oldest entry is located at the beginning of the list, and if a new entry is added to the list when said list is full, the oldest entry in said list is removed.

Abstract: The present invention relates to the transmission of push information to a handset. Before pushing a page to the handset, it is checked that the page belongs to the same service as the page currently display. If the page to be pushed belongs to a different service, it is not pushed. The risk of disruption to the original service is thereby reduced. Checking is preferably done by a gateway to which the handset is connected. The gateway can store details of the page last transmitted to the handset in order to facilitate the check.
