Abstract: The current invention is related to a micro device with microtubes that can be used as a heat exchanger for ultra fast cooling or heating of liquids. Using a damascene metal level in combination with thermal degradable polymer (TDP) enables the manufacturing of compact system of microtubes only separated by a monolayer of metallic barrier material. Due to the small distance (i.e. the thickness of the barrier) between two separate microtubes a highly efficient heat transfer between two fluids circulating in the microtubes is enabled.

Abstract: The present invention relates to a semiconductor device in which energy band gap can be electrically varied. An idea of the present invention is to provide a device, which is based on nanowires (306) embedded in a material (307) that exhibits a deformation when properly addressed, e.g. a piezoelectric material such as lead zirconate titanate (PZT), aluminum nitride (AIN) or zinc oxide (ZnO). The nanowires (306) can be reversibly strained by applying a local deformation to the piezoelectric material (307) by means of applying a voltage to the material. The resulting band gap variation can be utilized to tune the color of the light emitted from e.g. a LED or a laser. This is a consequence of the fact that the band gap is proportional to the frequency of the emitted light. In other fields of application, contact resistance in semiconductor junctions can be controlled, and this feature is highly advantageous in memories and switches.

Abstract: An optical disk player (101, 405) can run an application program (406) while also showing an audio/video presentation (402) to a user. In order to ensure uninterrupted viewing of the presentation for the user, the application program must secure application data from the optical disk (113) at the same time as audio/video data is being retrieved. This is facilitated if the audio and video data are stored interleaved together with the application data in a transport stream (111, 203, 306). Preferably the application data is in a format (306) that repeats frequently, so that the application program (406) can pick it up in many different parts of the audio/video presentation (402), without interrupting the audio/video presentation (402). An example of a format that repeats frequently is a carousel.
