Patent DE-3806414-A1 (DE)
Title: Method of copy protection for recorders
Inventor: SCHROEDER ERNST DIPL ING
IPC: G11B20/00
Filed: 1988-02-29
Abstract: The intention is to create a copy protection which, by simple means, allows certain copying processes and prevents others. The signal from a recorder of the first type (CD) contains a first additional signal (Z1), which allows a recording in a recorder of the second type (DAT). The recorder of the second type adds a second additional signal (Z2) into the signal, which prevents a further transcription. Particularly for CD/DAT and DAT/DAT transcription. <IMAGE>

Title: Method for identifying the occurrence of the same subscriber device address for a subscriber device during the formation of an address table in a ring-shaped communications network
Inventor: RICCATO ALDO DR
IPC: H04M9/02
Filed: 1988-03-04
Abstract: With the aid of this method, it is possible to identify whether the addresses (a) allocated to the subscriber devices (TLN) occur once or more often in a ring-shaped network. For this purpose, each subscriber device (TLN) transmits self-addressed address test packet information (ati) during the formation of an address table. If the respective subscriber device (TLN) receives the address test packet information (ati) in unmodified form, its address (a) occurs once. If the respective subscriber device (TLN) receives address test reply packet information (tai), its address (a) occurs at least twice. The subscriber device (TLN) with identical addresses (a) which is switched by the ring-shaped network essentially depends on the ring activation duration. This presupposes that, in each subscriber device (TLN), self-addressed packet information can be received, evaluated and subsequently removed from the ring-shaped network. <IMAGE>

Patent DE-3814321-A1 (DE)
Inventor: FRIEDRICH KLAUS GEORG DIPL ING
IPC: H04B3/44
Filed: 1988-04-28
Abstract: In a connection line with digital information transmission, where the voltage poles and the power-consuming units are connected in each case at the mid-points of transformers terminating the connection lines, it is to be ensured that partial currents of equal strength flow in each case through the individual connection wires. To achieve this, a control network is in each case connected in series to the windings of a transformer which are applied to a connection line, which network adjusts the strength of the partial currents flowing through the individual wires to exactly identical values. The control networks ensure that the partial currents flowing in opposite directions in the transformer windings cancel one another so completely that no magnetisation of the transformer core can take place. Any impairment of transmission quality which this might produce is thus prevented. <IMAGE>
Patent DE-3815422-A1 (DE)
Title: Aircraft
Inventor: ANDREADIS NIKOLAUS
IPC: B64C39/10
Filed: 1988-05-06
Abstract: In the case of an aircraft having wings, a fuselage and jet engines, the wings are arranged continuously under the fuselage using a low-wing monoplane construction. The wings are thus constructed as a continuous platform which essentially has a "delta" shape in plan view. The engines are arranged above the wings and the bottom of the aircraft is constructed to be essentially flat. This type of construction results in advantages with respect to the gliding characteristics and soaring characteristics in comparison with conventional aircraft whose size is of the same order of magnitude. By arranging the jet engines in the region of the wing leading edge, and by arranging guide plates or the like, which are connected to the jet engines, on the top of the wing, the noise emitted downwards from the aircraft is also reduced.
Patent DE-3832353-A1 (DE)
Title: Expanding the function of monitoring devices in shops and department stores
IPC: G08B13/196
Filed: 1988-09-23
Abstract: In shops and department stores it is known to use a monitoring device, which has a television screen, for monitoring customers (theft), which can be switched to one or more zones to be monitored. A more effective use is possible when the monitoring system is coupled to a sensor (detector) which indicates when and where a customer (living being) is in the area of the goods. The device should be switchable so that it keeps on monitoring collections of customers, but also a single person, as long as a cyclical sequence of the zones to be monitored is not desired. In each case, it should be possible for the device to be individually handled, that is to say it should immediately permit the monitoring of a specific location by means of manual operation.
Patent DE-3833709-A1 (DE)
Title: Diversity reception method for mobile reception
Inventor: BUCK WALTER DR
IPC: H04B7/08
Filed: 1988-10-04
Abstract: The diversity reception method for mobile reception, particularly in motor vehicles having at least three individual receiving antennas, is intended for also taking into consideration interference signals in the received signals in order to achieve an optimisation of the system. For this purpose, the respective differences of the transfer functions of the transmission paths between the transmitter and the respective antennas, on the one hand, and a reference signal, on the other hand, are determined. These differences are used for assessing the quality of reception of the individual antenna signals with respect to the reference signal. The antenna signal or the antenna signals with the greatest difference in the transfer function with respect to the reference signal are then given lower weighting for the diversity method and/or taken out of operation. These measures can be used in connection with virtually all diversity systems.
