Patent EP-0412286-A2 (EP)
Inventor: BRAEGAS PETER DIPL-ING
IPC: G08G1/09
Filed: 1990-06-30
Abstract: In a route-selective reproduction method for digitally coded traffic messages transmitted from a transmitter to a vehicle receiver, the only traffic messages which are to be sent to the driver are those which are relevant to his route. The route can be identified by means of transit time measurements of the receivable transmitters. The hyperbolic position-finding known for this purpose requires high computing expenditure on the receiver side. It is proposed according to the invention to store a coordinate grid in the receiver with transit time values of the synchronised transmitters which can be received in a given area and, by comparison of the measured transit time values with stored transit time values, to select the coordonates of the nearest transit time values in the coordinate grid as the vehicle location.

Abstract: In the case of an insertion and take-out apparatus for an injection moulding machine having mould parts (11, 12) which can be moved in relation to each other, at least one separate insertion member (16) and at least one separate take-out member (17) are moved by a direct drive coupling with the moved mould parts (11, 12) during the opening movement of the mould parts between an insertion point or take-out point and the one or other mould part and, as a result, the intermediate times between two processing operations of the injection moulding machine which are caused by inserting and taking out workpieces (18, 40) are shortened considerably. In addition, due to the special design and arrangement of the members and their drive parts, the operational reliability of the apparatus can be increased.   <IMAGE>

Abstract: A method for detecting a positional deviation of a contact hole formed in an interlayer insulator layer includes the steps of forming a detection conductor pattern on a substrate at a peripheral portion of a contact hole formation area in which a contact hole is to be formed, and forming a first insulating layer to cover the detection conductor pattern. Then, a first conducting layer of a predetermined pattern is formed on the first insulating layer to cover the contact hole formation area, and a second insulating layer is formed to cover the first conducting layer. Furthermore, a contact hole is formed at the contact hole formation area in the second insulating layer, and a second conducting layer is deposited on the second insulation layer so that the second conducting layer is deposited within the contact hole. Thereafter, a short-circuit between the detection conductor pattern and one of the first and second conducting layers is detected. When the short-circuit is detected, it is judged that the formed contact hole adversely deviates from a proper position where the contact hole is to be formed.

Abstract: A precision switched current source uses two transistors, preferably bipolar devices, with one transistor (Q1) establishing a reference current and the second transistor (Q2) connected to provide an output current which proportionately mirrors the reference current. A voltage controlled switch, preferably a field effect transistor (FET) (T1), is connected between the bases of the two bipolar transistors (Q1, Q2), and is switched to open and close that connection. The mirrored output current is thus switched on and off, under the control of the FET switch (T1). A second switch (T2) may be provided and operated inverse to the first FET switch (T1) to discharge the base of the output bipolar transistor (Q2) when that transistor is off.

Abstract: A technique for establishing and maintaining full duplex communication between two stations connected to a token ring network, without dedicated connections. In an auto-configuration full duplex mode of operation, each station ascertains whether there are only two active stations on the network and, if so, performs an exchange of frames with the other station to establish full duplex communication. Once established, full duplex communication can proceed at a greater bandwidth than communication in a token ring network, and without latency delays and distance limitations associated with token ring networks. Periodic checks are made by each station in full duplex communication, to ascertain if the other station is still participating or if any third station has become active. In either case, stations in the auto- configuration mode revert to token ring mode automatically. In a variant form of the invention, stations can operate in a fixed full duplex mode, in which the detection of tokens or third stations are merely reported and do not necessarily result in reversion to the token ring mode.

Abstract: In RDS programme selection in known mobile receivers, the data contained in the station memory are transferred to a working memory and all alternative frequencies are briefly tuned and evaluated. If the same PI code is not identified in any of the alternative frequencies, a search run for the same programme chain is initiated. In the case of stored individual stations or programmes with few, poorly receivable alternative frequencies only, a search run of this type is often initiated in this way, even though favourable reception conditions exist a short time later. The object of the invention is therefore to indicate a selection strategy in which an unnecessary search run is suppressed. This object is achieved by assigning a rank, dependent on reception quality, to each frequency in the programme selection when the alternative frequencies contained in the station memory are checked. The reception quality is checked according to RDS quality and RF reception quality such as multipath reception, received field strength and transmitter centre. If no frequency with adequate RDS quality is found, the frequency with the highest field strength and identified RDS signal radiation is set, provided that adequate audible quality is inferred from the RF reception quality. The frequency thus set remains set for a predetermined time. A search run is initiated within the required programme chain only if no RDS identification was possible during this time.
