Publication number: 20070148437Abstract: The invention relates to biocompatible, thermosensitive polymers that can be heated, with the aid of a high-frequency magnetic alternating field, by encapsulating magnetic and/or metallic colloids or magnetic nanoparticles. As a result of the inductive heating of the polymer matrix, physical structure changes are triggered in the polymer matrix that lead to the bioactive substances encapsulated in the matrix being released within a short period of time. This “stimulus-response” principle is employed for the production of controllable drug depots, contrast-intensifying media for NMR diagnostics or manipulable micro-tools, as media for blocking blood vessels and as controllable porogens in the production of membranes.Type: ApplicationFiled: October 22, 2004Publication date: June 28, 2007Applicant: MagnaMedics GmbHInventor: Detlef Müller-Schulte

Patent number: 7047436Abstract: A digital microelectronic circuit comprises a clocked data-processing unit (1) and a converting unit (2) which reads in data present at the output of the data-processing unit, performs a predetermined converting operation on the data and passes on the converted data. The converting unit is realized in an asynchronous logic circuit, such that the period of time for performing the converting operation is shorter than the shortest time interval to the next change of the data present at the output of the data-processing unit. In this way, fast, serial synchronous processes can be parallelized from the point of view of the slow synchronous system in synchronous systems which are slow relative thereto by using asynchronous logics, without a further high-frequency clock system being required.Type: GrantFiled: June 25, 2001Date of Patent: May 16, 2006Assignee: Koninklijke Philips Electronics, N.V.Inventors: Sabine Sommer, Detlef Müller, Markus Feuser
