  • Publication number: 20130022746
    Abstract: Inks that contain ionically stabilized dispersions and selected polyurethane ink additives are described. These ionically stabilized dispersions are obtained from polymeric dispersants where the hydrophilic components are minimized. These stabilized dispersions can be utilized to prepare ink jet inks which when printed result in improved optical density, chroma, gloss and especially distinctness of image. The stability of the ionically stabilized dispersions are sufficient for ink jet inks. The polyurethane ink additives are chosen from polyurethanes which are urea terminated or crosslinked.

  • Publication number: 20120016861
    Abstract: An application programming interface (API) includes an interface implemented by a software program or firmware program which enables an application to interact with other software or with firmware. An API can facilitates interaction between different software programs. Registration of an application can be the notification, by an API which corresponds to a non-native application, to native applications and to a core search framework of a mobile communications device. A core search framework provides a mechanism which enables an application to register as a provider of searchable data. A media application provides a search API media subset which enables non-native applications to register and enables non-native applications to indicate media type categories for which non-native applications may be searched. Registered non-native applications are launched based upon the type of media utilized by a media application.

  • Publication number: 20120009906
    Abstract: A system and method of resuming media playback on a mobile device can include playing media on a mobile device and outputting audio associated with the playing media to an audio output device. The media can be paused in response to receiving an interrupt request. A play request can be received to resume playing of the media on the mobile device. A determination can be made as to whether the audio output device is communicatively coupled to the mobile device. The media can resume play in response to the audio output device being communicatively coupled to the mobile device. In another implementation, media can resume play if a determination is made that the audio output device outputting the audio associated with the media before the interrupt request is the same audio output device that will output audio associated with the media after the interrupt request.

  • Publication number: 20110302017
    Abstract: A mobile coupon redemption system enables a customer to receive a mobile coupon offer on his mobile phone, and to display the offer to a merchant. The customer is prompted to obtain a “merchant code” from the merchant, who obtains the merchant code from a local secure hardware token. The customer then communicates the merchant code by his mobile phone to a remote coupon application server, which validates to the merchant code, records the merchant and customer information, and validates the coupon for display to and redemption by the merchant.
