Method and device for recovery and retention of CO2 out of exhaust gas of combustion engines

The invention delivers a solution, which is an energetically and ecologically better method, along with the required device for separating carbon dioxide from the exhaust fumes of combustion engines, based on thermodynamic arrangements. To do so, the gas mass, which is fed to and exhausted from the engine is conditioned in such a way that it is possible to lower the exhaust conditions enough for 〖CO〗_2 condensation. The conditioning is done in regards to temperature and pressure. Doing so causes the carbon dioxide to change its aggregate state to liquid, which makes separation and storing of 〖CO〗_2 possible. The energy for this process is taken out of the engine exhaust and from the engine power. The energy exchange is done with heat exchangers. An additional medium is used as heat storage, while the enthalpy of this medium can be used for recovery processes.

Method and device for automatic readjustment of Cochlea implants

It is known, that the electric stimulation of the Stapedius muscle by the brain is not following a 0-1 scheme. Rather, it is following in a continuous curve which correlates with the signal intensity. Because of this, the invention aims to deliver a method for continuously (re-) calibrating every amplification factor.
The invention solves this task by using an integrated control system. This system compares the outer microphone volume with a target curve, which causes the Stapedius muscle to behave in a certain way. If the measured muscle behavior is different from the expected one, this system changes the amplifying parameters.
By observing and storing the Stapedius activity it is possible to make the amplification factors dependent on the volume, which makes a nonlinear amplification possible.

4D-PET- and SPECT-Phantom model compounds with anatomic realistic contours

The invention relates to a method which produces repeated and reproducible 4D-movements of a phantom model for measurements in PET, SPECT, CT and radio oncologic accelerators. According to the invention, the usable phantoms illustrate realistic tumor geometries with-out interfering glass and plastic partitions. With the help of the invention, PET-, SPECT- and CT-data can be evaluated. Additionally new algorithms of re-construction and the influence of ana-tomic movements on medical imaging can be tested for all of the three tech-niques. With the help of a kinematic con-catenation which consists of two rota-tional and one prismatic joint, the 3D-movements of the phantom models can be adapt on trajectories analog to the human respiration.

Method for the measurement of intraocular pressure

The present invention describes a measur-ing device that allows for the accurate de-termination of intraocular pressure by attaching a measuring body to the closed eyelid. The measuring principle is based on the subjective intraocular pressure es-timation by the palpating finger and will be implemented in an objective measuring method by the device described herein.
The existing development is based on an approximation of the contour of the in-dented eye which flattens the enveloping tissue and simultaneously adapts to the contour of the eye’s surface. In the broad-est sense it is as an adaptation of covering eyelid tissue to an expanded surface of the eye. The device basically consists of two pressure units made from silicone, which are independently and resiliently mounted from another. The pressure of the first membrane is applied via a struc-turally designed spring and serves to smooth the upper eyelid and the indirect fixation of the eyeball. The pressure of the second membrane is applied via two springs and is continuously increased to-wards measurement point when no further flattening of the second membrane is visi-ble. Consequently, the pressure character-istics of the eye are transferred from the first membrane to the second membrane. The flattening is monitored by an LED light reflex and the maximum value can thus be easily determined.
The present invention is of particular ad-vantage for measurements of intraocular pressure in patients with an injured or dis-eased cornea.
