Abstract: There is disclosed a method for converting multi-level image data into binary image data and an apparatus therefor. An average density is calculated from the already binarized density of pixels positioned in a predetermined area around an object pixel, and the threshold value for binarization is set by adding a fixed bias value and varying dither signals to the average density, and the error generated in the binarization is distributed to the unbinarized pixels positioned behind. The addition of the fixed bias prevents formation of a spot-free white area in the vicinity of an edge or in the initial stage of processing, and the addition of dither signals prevents texture formation in the low density area.

Abstract: A method for carrying out an authentication check in a mobile telephone system in which an authentic base station (BS) serves a plurality of mobile stations (MS1-MSn). It is earlier known to carry out a unidirectional check from the base station (BS) to a calling mobile station (MSk). A false base station (BSf) is able, in this way, to carry out a false authentication check, by collecting a number of so-called RAND-Response pairs. In order to avoid this, there is introduced a further unidirectional authentication check, base station-mobile station, and also an authentication check from the mobile station to the base station. According to one embodiment of the method, the unidirectional check is excluded and only the bidirectional authentication check is carried out.

Title: A method of equalization in a receiver of signals having passed a transmission channel.
Inventor: MADSEN BENNY
IPC: H04L25/03
Filed: 1991-04-30
Abstract: In an equalizer of the DFE type (Decision Feedback Equalizer) for equalization in a receiver for electromagnetic signals having passed a transmission channel, a plurality of weight factors or tap coefficients is used in a feedforward part as well as in a feedback part. Values based on an estimate of the impulse response of the channel are selected as a start condition of these coefficients. The estimate values are used in complex conjugated state in the feedforward part, which corresponds to a so-called matched filter, and the autocorrelation of the estimate of the channel impulse response is used in the feedback part. Detection of the data bits can begin at an optional training sequence and proceed from this. The estimate of the impulse response of the channel may also be used for synchronization, and the received signals may be phase or frequency adjusted before detection.

Abstract: A fabrication method for forming SOI structures wherein perfect material is grown epitaxially on a substrate and then, through a series of selective etches and oxidations, an insulating layer is formed below the epitaxial silicon. In the method, low temperature epitaxial techniques are employed to grow a layered structure including a first layer (12) of p++ silicon on a substrate wafer, a layer (14) of intrinsic silicon is then formed on the first p++ silicon layer, and a second layer (16) of p++ silicon is formed on the intrinsic silicon layer, and finally a layer (18) of p-silicon is fabricated on top of the second p++ silicon layer. Grooves (24, 26) are formed through the p- layer (18), the second p++ silicon layer (16), the intrinsic silicon layer (14), and stopped in the first p++ silicon layer (12). An etch is then employed to remove the intrinsic layer long enough for the p++ silicon layer (16) to be totally undercut, leaving an air gap between the two p++ silicon layers. An oxidation step is then performed to form a bottom insulator consisting of the oxidized first p++ silicon layer (12) and on an upper insulator consisting of the oxidized second p++ silicon layer (16).
