Patent SE-512965-C2 (SE)
Inventor: KORSFELDT DAN
IPC: H04L25/06
Filed: 1998-09-15
Abstract: The invention relates to a method and an arrangement for estimating a DC-offset in at least one analog output signal from an analog front end of a radio receiver in a TDMA-based radio communication system. A sequence of measurement intervals is defined (501) such that for each burst transmitted on a radio carrier frequency by mobile stations operating in a common cell, there is at least one measurement interval during which no overlap with a second burst occurs. The analog front end of the radio receiver generates (502) the analog output signal by performing analog signal processing of received radio signals. Digital samples are derived (503) from the analog output signal. A measure of received signal power in each measurement interval in a framing period is estimated (504). At least one measurement interval during the framing period is selected (505) in dependence of said measure. The DC-offset is estimated (506) using samples belonging to said selected measurement interval.

Abstract: The invention relates to a method and a device for drying substrates (1). As said substrates are brought out of a liquid (2), a meniscus (6) of said liquid (2) forms between the surface of the substrate and the liquid, and is heated. According to the invention, the meniscus is heated using a gaseous medium (7). This has the advantage of both reducing the cost of the method and the device and drying the substrate effectively, reliably and quickly. Alternatively, the meniscus (6) can be heated using the substrate (1) with which it is in contact. This has the same or similar advantages.

Abstract: The invention relates to a method and a micromixer for producing a dispersion. During the production of dispersions using static micromixers, the distribution of the achieved particle sizes cannot be adjusted directly. The aim of the invention is to provide a method for producing a dispersion of two liquids A and B which allows the distribution of particle sizes to be adjusted. This is achieved firstly by splitting a liquid stream of liquid A into spatially separate liquid laminae and combining said laminae with a liquid stream of liquid B. Mechanical oscillations assist the fragmentation of the liquids into the particles which form the dispersion. A corresponding micromixer has a housing (60a, 60b), a mixing element (62) for splitting at least one liquid stream into liquid laminae, a mixing area and at least one mechanical oscillator (65).
