Abstract: A system and method are for adjusting ringtone volume on a telephony device based on a current user-selected volume level used for digital audio playback. For example, a method according to one embodiment of the invention is implemented within a telephony apparatus having digital audio playback and ringtone playback capabilities, the method comprising: decoding and playing digital audio content in response to user input; monitoring the playback of the digital audio content to determine a first volume level associated with the digital audio content; receiving an incoming telephone call on the telephony apparatus; adjusting a second volume level associated with a currently-selected ringtone based on the value of the first volume level; and playing the currently-selected ringtone at the adjusted second volume level.

Abstract: Description of an inkjet printing method, whereby a second and optionally a third and/or additional ink(s) is/are printed on top of each other or immediately next to each other, whereby (i) the first ink contains a coloring substance precipitable by a precipitation reagent, (ii) the first or the second ink contains the precipitation reagent in temporarily passivated form, and (iii) the first, second or third ink contains an activator for the temporarily passivated precipitation reagent, with the proviso that the temporarily passivated precipitation reagent and the activator are not present in the same ink. The method prevents or reduces the problem of mixing or running into each other of two inks at their border lines. The temporarily passivated precipitation agent can be a complexed multi-valent metal ion, which is displaced from the complex by the activator.

Abstract: Described is an ink for use in ink jet printers, comprising (a) a solvent, which consists at least of approximately 80% of a homopolar, non-watery solvent, (b) a pigment dispersed in the solvent and (c) a copolymer of vinyl-pyrrolidone with one or several long-chain .alpha.-olefins with at least 6 carbon atoms, specifically with 6 to 24 carbon atoms. Properties of the ink are as follows: reduced color bleeding, reduced penetration of coloring agent into the surface of the paper, improved optical density and improved storage stability.
