20110261857 | METHOD FOR EVALUATING THE SOLUBILITY OF A CRYSTALLINE SUBSTANCE IN A POLYMER - A viable strategy to enhance the bioavailability of poorly soluble drugs is to use amorphous solids in place of the more commonly used crystalline solids in pharmaceutical formulations. However, amorphous solids are physically meta-stable and tend to revert back to their crystalline counterpart. An effective approach to stabilizing an amorphous drug against crystallization is to disperse it in a polymer matrix. The drug's solubility in the chosen polymer defines the upper limit of drug loading without any risk of crystallization. Measuring the solubility of a drug in a polymer has been a scientific and technological challenge because the high viscosity of polymers makes achieving solubility equilibrium difficult and because pharmaceutically important drug/polymer dispersions are glasses, which undergo structural relaxation over time. The invention provides a method based on Differential Scanning calorimetry (DSC) for measuring the solubility of crystalline drugs in polymeric matrices. The method relies on the detection of the dissolution endpoint of a drug/polymer mixture prepared by cryomilling. | 2011-10-27 |

20110261952 | FACEPLATE ASSEMBLY FOR WALL MOUNTING A PHONE - A faceplate assembly includes a cover plate having a front wall and a rim surrounding a perimeter of the front wall. The rim has a rim opening therethrough. The front wall has a pair of mounting posts extending therefrom that are configured to be received in keyholes of a phone to support the phone. A subplate configured to be mounted to a wall outlet. The subplate has an end wall and a base with a base opening therethrough and the subplate is configured to hold a modular jack. The cover plate is coupled to the subplate such that the rim and base openings are aligned with one another and are configured to receive a patch cord therethrough. | 2011-10-27 |
20110261953 | METHOD FOR TESTING CRYPTOGRAPHIC CIRCUITS, SECURED CRYPTOGRAPHIC CIRCUIT CAPABLE OF BEING TESTED, AND METHOD FOR WIRING SUCH CIRCUIT - The present invention relates to a method for testing cryptography circuits. It also relates to a secure cryptography circuit capable of being tested. The cryptography circuit includes registers and logic gates, and a test thereof performs a differential power analysis on the registers of the circuit. A cryptography circuit being secure and including a first half-circuit associated with a second half-circuit operating in complementary logic, the electric power supply of the first half-circuit is separated from the electric power supply of the second half-circuit, the differential power analysis being carried out in parallel on each half-circuit, the two power supplies being combined into one and the same electric power supply after the test. | 2011-10-27 |
