IPC: A01D41/127
Filed: 2002-07-29
Abstract: A combine with a throughput dependent speed control includes an angle sensor responsive to uphill, downhill and sidehill slopes. When the combine is angled from a level position, harvest speed is lowered to prevent grain losses from increasing above a target level. The control continuously learns tilt angle, loss and throughput correlation, and the speed reduction is selected based upon the learned correlation. In the preferred embodiment, throughput is estimated utilizing rotor variable drive actuator pressure (RVDAP), and a target RVDAP is modified for short periods of time in accordance with the learned correlation.

Title: Needle-less injector of miniature type
Inventor: HENKE STEFAN
IPC: A61M5/30
Filed: 2001-03-02
Abstract: Needleless injectors for liquids are known from the art in a variety of designs that are adapted to different conditions of application. The inventive needle-less injector is designed as a hand-held device. It comprises a lockable tensioning system, an energy-storing spring (36), a hollow piston (37) displaceable within a cylinder (38), and a nozzle (39). The hollow piston is provided with a valve body on its one end. The storage container (44) for the liquid is disposed within the hous-ing. The lockable tensioning system is tensioned by counterrotating the two housing parts (31; 32), thereby withdrawing the hollow piston (37) from the cylinder (38). At the same time the amount of liquid required for the injection is withdrawn from the storage container (44) and transported through the hollow piston to the pump chamber (34). When the lockable tensioning system is released, the amount of liq-uid is ejected from the pump chamber through the nozzle. The needleless injector is easy and reliable to handle also for unpracticed people. It is used for intracutaneous injections of a medical liquid into biological tissue, for injecting a liquid containing an active substance into a plant or for injecting a liquid through a membrane into the space behind said membrane.

Title: Method and arrangement in connection with optical bragg-reflectors
Inventor: STUBBE RAOUL
IPC: H04B10/43
Filed: 2001-06-26
Abstract: A method of establishing transmission of light through a chirped Bragg-reflector, a method of analysing the power spectrum of a light signal by means of a chirped Bragg-reflector, and an arrangement for analysing the power spectrum of a light signal. The Bragg-reflector reflects, in an unperturbed state, essentially all incident light within a predefined wavelength range.  The methods comprise the steps of directing the light to be analysed into an input end of a light guiding structure, such as an optical fibre, which light guiding structure is provided with a Bragg-reflector, and sending an acoustic pulse along said light guiding structure, thereby effectively lowering the reflectance of the Bragg-reflector for a certain wavelength at a certain time.  By monitoring the light thus transmitted through the Bragg-reflector, power spectrum analysis of the incident light is obtained.
