A system for automatically initiating a travel mode of a media-playback device is disclosed. The system operates to evaluate vehicle presence factors and determine whether the vehicle presence factors indicate that the media-playback device is in a vehicle. Upon determining presence of the media-playback device in a vehicle, the travel mode is performed using the media-playback device.

Vehicle detection for media content player

A system for automatically initiating a travel mode of a media playback device is disclosed. The system operates to determine that the media playback device is connected to a vehicle media playback system based on an identifier provided from the vehicle media playback system. Upon determining presence of the media playback device in a vehicle, the travel mode is performed using the media playback device.

The invention concerns a drill bit, intended to be used with a down-the-hole drill and comprising a drill head () with a front surface provided with drill pins () and a shaft (), whereby the shaft is narrower than the drill head and intended to be inserted in a manner that allows axial sliding into the end of a drill chuck that is a component of a down-the-hole drill and which shaft has a rear end part () that is somewhat thickened with a plane striking surface () against which a hammer piston () that is a component of the down-the-hole hammer drill is arranged to impact, that the drill head when viewed along its axial direction has a cylinder-shaped forward part () provided with cuttings channels (), a rear cylinder-shaped part () that is located for the reception of drill cuttings at the same level or somewhat below the bottom () of the cuttings channels, whereby the diameter (D) of the forward part is greater than the diameter (D) of the rear part. In a drill bit that has high performance and a long useful life, and that is furthermore well-suited to be used for directed drilling, the cylinder-shaped forward part () of the drill head () has an axial length (L) from the main plane of the front surface to a shoulder plane () located between the drill head () and the shaft () that is greater than the axial length (L) of the cylinder-shaped rear part () of the drill head.

Drill bit for a down-the-hole drill

An arrangement for a down-the-hole hammer drill, for use in soil consolidation by jet grouting, and comprising a cylindrical machine housing, an impact mechanism driven by pressurised fluid that impacts onto a drill bit mounted in a chuck in the machine housing that allows reciprocating motion, whereby the machine housing has a central supply line for the driving fluid to the impact mechanism in which channels in the drill bit constitute outlets for used driving fluid. The machine housing is provided with a grouting nozzle for jet grouting, that the grouting nozzle is directed in a sideways direction and arranged at the periphery of the wall of the machine housing, that a rinsing channel for conducting a grouting mixture through the machine housing to the said grouting nozzle is arranged whereby the rinsing channel for the grouting mixture is separate from the supply line for the driving fluid of the impact mechanism.
