| 20110276003 | INTEGRATED MICRONEEDLE ARRAY AND A METHOD FOR MANUFACTURING THEREOF - The invention relates to a method of manufacturing of a microneedle array comprising the steps of selecting a soft production mold comprising a set of microscopic incisions defining geometry of the microneedles, said soft production mold being capable of providing the microneedle array integrated into a base plate; using a filler material for abundantly filling the microscopic incisions of the soft production mold thereby producing the microneedle array with pre-defined geometry integrated into the base plate; wherein for the filler material a water or alcohol based ceramic or polymer-ceramic slurry is selected. The invention further relates to a microneedle array, a composition comprising a microneedle array, a system for enabling transport of a substance through a barrier and a system for measuring an electric signal using an electrode. | 11-10-2011 |
| 20110203945 | method of preserving a sensor in a container and a container containing a sensor and a storage solution - The invention relates to a method of preserving a sensor in a container, said sensor comprising a sensing area of metallic or a semi-conducting material covered with molecules having a MW>100 Dalton, said molecules being bound to the material wherein at least the sensing area of the layer is kept submerged in a storage solution, said storage solution having a composition that consists for at least 80% by volume of at least one compound chosen from water, ethanol, triethylene glycol and isopropanol, with the provisios that | 08-25-2011 |
| 20110171712 | SELF-ASSEMBLING TISSUE MODULES - The invention relates to a new approach to constructing cellular aggregates in vitro and their use in methods for producing 3D-tissue constructs in a modular way. | 07-14-2011 |
| 20110046458 | DEVICE FOR DETECTING A MEDICAL CONDITION OR DISEASE - The invention relates to a capsule or chip or sensor comprising a marker/detector and signalling device/method associated with the development of a medical condition/disease and to its use. This In Situ Lab On a Chip Signalling device (ISLOGS device) is used for detecting a medical condition/disease in situ or in vivo (inside the body), for example by swallowing it for testing in the digestive tract or by putting it into the vagina, mouth or nose. All reactions takes place in the body and when the test result is positive the device will notify the subject by colorizing the tested body fluid or biomaterial (for example faeces, urine or saliva) or the device itself. The detection is made outside of the body when the biomaterial or ISLOCS device has left the body. | 02-24-2011 |
| 20100242142 | SCANNING PROBE MICROSCOPE - The invention relates to a scanning probe microscope comprising: a specimen holder holding a specimen; and a probe for scanning the relief of the upper surface of the specimen, which probe is movable in a vertical direction and two orthogonal horizontal directions, wherein the upper surface of the specimen is tilted relative to at least one of the two orthogonal horizontal directions. | 09-23-2010 |
| 20100041987 | Imaging Apparatus And Method - A thermoacoustic imaging apparatus comprises an electromagnetic radiation source configured to irradiate a sample area and an acoustic signal detection probe arrangement for detecting acoustic signals. A radiation responsive acoustic signal generator is added outside the sample area. The detection probe arrangement detects both signals generated in a sample area in response to the irradiation and an acoustic signal from the radiation responsive acoustic signal generator that has traveled through the sample area. A computing system distinguishes first acoustic signal detections attributed to the acoustic signal generated by the radiation responsive acoustic signal generator and second acoustic signal detections attributed to the acoustic signals generated by the sample area. The computing system performs a tomographic computation of an acoustic transmission parameter as a function of a position in the sample area from the first acoustic signal detections. The acoustic transmission parameter may be a speed of sound or absorption. The acoustic transmission parameter may be used to correct the computation of a thermoacoustic image. | 02-18-2010 |
| 20090278791 | MOTION TRACKING SYSTEM - A motion tracking system for tracking an object composed of object parts in a three-dimensional space. The system comprises a number of magnetic field transmitters; a number of field receivers for receiving the magnetic fields of the field transmitters; a number of inertial measurement units for recording a linear acceleration; a number of angular velocity transducers for recording angular velocities. The system further comprises a processor for controlling the transmitters and receiving signals coming from the field receivers and the inertial measurement unit; which processor contains a module for deriving orientation and/or position information of the constituent object parts of the object on the basis of the received signals. The processor is configured for intermittently controlling the transmitters transmit at a predetermined frequency, wherein the position and/or orientation information is derived by periodically calibrating the motion information coming from the inertial measurement unit with the motion information coming from the magnetic field receivers. | 11-12-2009 |
| 20090002714 | Optical Device Comprising a Cantilever and Method of Fabrication and Use Thereof - The present invention provides an optical device, comprising an optical fiber and a cantilever that is arranged on an end of the optical fiber; The cantilever may be an integral part of the optical fiber, and may have a length that is substantially equal to a diameter of the optical fiber. Measurement means for measuring a displacement of the cantilever are connected to an opposite end of the, optical fiber. A method of measuring a displacement using the optical device comprises the steps of: —arranging measurement means, comprising a light source, on an opposite end of the optical fiber; —using the light source to send a beam of light into the optical fiber; —measuring the interference of light that is reflected on the end op the optical fiber and light that is reflected on the cantilever; and determining the displacement of the cantilever relative to an intermediate position dependent on the measured interference. | 01-01-2009 |
