Patent DE-19744021-A1 (DE)
Title: Wireless data transmission simulation method
Inventor: KRUK ANTON DIPL ING
IPC: H04B17/00
Filed: 1997-10-06
Abstract: The method involves transmitting data of a first predetermined transmission protocol with predetermined data transmission parameter via a transmission path (3,4). Real measurement values are determined which describe the faulty behaviour of the data transmission via a radio channel in dependence of the predetermined parameters. The real values and the first data protocol are transferred to a simulation unit (9).  The data transmission is simulated with at least a further predetermined transmission protocol and changed parameters with respect to the transferred real values. The faulty behaviour of the transmission path can be determined for the at least further transmission protocol.

Title: Two-chamber aerosol can manufacture
IPC: B65D83/14
Filed: 1997-10-17
Abstract: The flexible membrane (4) is introduced through the top open end of the container. The latter is then formed to an outer container (1) containing both chambers. An Independent claim is included for equipment carrying out the method. Preferred features: The outer container blank open end is narrowed to a neck (8) forming the dispensing opening. The necking process is impact extrusion, swaging and/or roller-edging. The edge is turned (7). The can is aluminum. Its basal opening (3) assists membrane positioning. The membrane is fixed at the edge (13) to the container or its blank. The flexible membrane is a bag liner (4) preferably of plastic, laminates, composites, layered composites, or thermoplastics, especially thermoplastic, thermoplastic laminates, or of layered composites alone or with thermoplastics. The liner edge (13) is thermoplastic, fused-onto the outer container, following forming. Liner attachment follows forming, by wrapping the liner edge over the container opening edge. During attachment or turning the edge over, the liner is lifted pneumatically or mechanically by means of a handling unit, acting through the bottom opening. Lifting is assisted by compressed air and/or a slide (9). An attachment unit (10, 12) comprises a ring of  heated tool segments (10) griping the edge of the liner and pre-attaching it to the inner edge (11) of the container. The fastening tool (12) is heated and has a spreading edge-turning section. This lays the projecting liner edge over the opening edge, fusing and hence connecting it, permanently sealed to the edge.

Patent DE-19815701-A1 (DE)
Inventor: CINKLER KALMAN
IPC: H04L25/03
Filed: 1998-04-08
Abstract: The invention relates to a method for demodulating a carrier wave modulated by a digital symbol sequence and transmitted via a noisy channel. According to the invention the ideal shapes of the edges of the possible transitions between two symbols are known and stored (reference edges), and a received edge is scanned and digitized at a scanning frequency which is equal to a multiple of the frequency of the symbol sequence. According to the invention, for the detection of a received and scanned edge the total scanning values are used to obtain the Euclidean distances to at least two reference edges and the reference edge with the shortest Euclidean distance is selected. In a preferred version, a Viterbi algorithm is not, as in the case of known CPM demodulation methods, applied to an estimated symbol sequence but to a sequence of estimated edges, whereby the corresponding Euclidean distances of the edge received during a symbol duration are treated by the reference edges as the cost of a Trellis branch of the Viterbi algorithm.
