The invention relates to a method for coordinating at least one first transmission from a multipoint transmitter or to a multipoint receiver and at least one second transmission from a single-point transmitter to a single-point receiver in a radio communication system. The method comprises the step of reserving at least one first radio resource (SI-F1 to S3-F1, S9-F1, SI 0-F1, SI-F2, SI-F1 b-BW2 to SI 0-F1 b-BW2, SI-F2b-BW2) for the at least one first transmission for at least two serving areas of the radio communication system and further reserving at least one second radio resource (S4-F1 to S8-F1, SI-F1 b-BW1 to SI 0-F1 b-BW1, SI-F2b-BW1, SI-F1 b-BW3 to SI 0-F1 b-BW3, SI-F2b-BW3) for the at least one second transmission for the at least two serving areas). The invention further relates to a network node (NS1, NS2) for coordinating at least one first transmission from a multipoint transmitter or to a multipoint receiver and at least one second transmission in a radio communication system and to a mobile station for use in a radio communication system.

A ventilation device (10), in particular for a vehicle interior, has a frame (12) which includes at least one opening (16), and at least one non-return flap (20), the non-return flap (20) having at least one recess (26) provided thereon through which a holding member (22) provided on the frame (12) extends, and the non-return flap (20), depending on the active pressure differential, being movably adjustable on the holding member (22) between a closed position, in which the non-return flap (20) rests against the frame (12) and closes the at least one opening (16) of the frame (12), and an open position. The holding member (22) is deformable between a mounting position, in which the non-return flap (20) can be mounted to the holding member (22), and a locked position, in which the non-return flap (20) can not be dismounted.

A pencil, in particular a cosmetic pencil, comprising a cartridge, a lead held such that it can move axially relative to the cartridge, and a shaper for shaping the working end of the lead. The pencil can adopt an operating state in which twisting of the shaper relative to the lead and/or the cartridge in a first angle of rotation section leads to axial displacement of the cartridge relative to the lead in the direction away from the shaper, and in a second angle of rotation section leads to axial displacement of the lead in the direction towards the shaper.

The present invention relates to a biphasic microalgae extract comprising 15-95 wt. % of an aqueous phase and 5-85 wt. % of an oil phase, said extract containing at least 1% by weight of total fatty acids of ω3-fatty acids selected from the group consisting of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and combinations thereof, said extract further being characterized in that it contains: • 40-100% by weight of the oil phase of lipids selected from triglycerides, diglycerides, monoglycerides, phosphatides, free fatty acids and combinations thereof; • 0.01-10% of carotenoids by weight of the oil phase; • 0.5-10% of sodium chloride by weight of the aqueous phase; • 0-3 wt. % of non-dissolved material other than dispersed droplets of aqueous phase or oil phase; and • 0-10% of C1-5 monoalcohol by weight of the aqueous phase. Together the aqueous phase and oil phase of the biphasic extract contain essentially all the lipid material that was originally contained in the microalgae biomass, i.e. both apolar lipids (e.g. triglycerides, free fatty acids) and polar lipids (e.g. glycolipids, phospholipids). The invention also provides processes for extracting an oil phase from wet biomass of micro-organisms. These processes do not require the use of apolar organic solvents and produce a biphasic extract that can easily be downstream processed to produce ω3-PUFA containing oil in high yield.

The present invention relates to a method and a device for determining the spatial position of a sensor, in which a rough position information initially is determined by rough detection of the position of the sensor, and then the more accurate position of the sensor is obtained by measuring at least three reflectors mounted on the sensor with a laser tracker, wherein the search region of the laser of the laser tracker is limited for the reflectors with reference to the rough position information.
摘要:
A microprocessor is used to control the temperature of a laser emitter and thereby regulate the wavelength of optical signals from the laser. A serial interface in the microprocessor provides input and output lines to a host device, and temperature lookup tables are stored in nonvolatile memory. Control logic processes information stored in the memory as well as information on operating conditions of the laser emitter to precisely control the temperature of the laser emitter. A thermo-electric cooler adjusts the temperature of the laser emitter.
