Inventor: SPERLICH JOSEF DIPL-ING
IPC: H04M11/02
Filed: 1989-07-21
Abstract: It has already been proposed to connect radio paging centres to a communications network (ISDN) with a common signalling channel. In this arrangement, all signalling information items are to be transmitted via this common signalling channel within the network. In order to take up the transmission channels of the communication network as little as possible for the radio paging, the existing common signalling channel is used for the transmission both of signalling information and of call information which is intended for the called paging receiver.

a second blocking region (38) interposed between said base (30) and said emitter (34), 
said blocking regions (36, 38) having sufficiently low impurity concentrations that substantially no charge trans­port can occur by an impurity conduction mechanism.

Abstract: Through first and second external terminals (T₂, T₃), fixed potentials are applied to both ends of a first stage of ladder resistor network. A second stage of ladder resistor network is connected at one end to a second transistor (Q₂). The first external terminal (T₂) is connected to a first transistor (Q₅) through a resistor (R M ), the resistor (R M ) and the resistors of the first and second stage of ladder resistor networks being of the same kind. A positive input terminal of an operational amplifier (1) is connected to a node (A) between the resistor (R M ) and the first transistor (Q₅). A negative input terminal of the amplifier (1) receiving a reference voltage is connected to the second external terminal (T₃). The first and second transistors (Q₂, Q₅) are driven by the output signal of the amplifier (1). The amplifier (1) cooperates with the first transistor (Q₅) such that a potential at the node (A) is equal to the potential of the reference voltage. As a result, a current (I₂/M (M = constant)) flowing through the resistor (R M ) is proportional to a current (I₂) flowing through the first stage of ladder resistor network. Since the current, which is based on the operation of the second transistor (Q₂), flows into the second stage of ladder resistor network, the current flowing through the first transistor (Q₅) is propor­tional to a current (I₃) flowing through the second stage of ladder resistor network.

Abstract: A method of tracing the paths used in execution of a computer program uses the state of a single bit to denote the referencing of a trace point in the program. Preferably, the trace points are logically located near the program branch points. Preferably, also, one or more bit maps are arranged in a known state at the beginning of program execution and then state of a particular bit in one of the bit maps is set when the associated trace point is referenced. Each bit can be associated with a particular trace point according to its position in the bit maps. After program execution, the bit maps can be compared to the source listing to determine which trace points were referenced. The use of single bits to denote the referencing of trace points minimises the degradation of performance efficiency of the target program. By initialising the bit maps to a known state at the beginning of each program execution and then transferring the resulting bit maps to retentive storage at the end of each program execution, tracing can occur continuously. A method of installing an embedded tracing capability in a target program is also disclosed.

Abstract: A method is disclosed for detecting the presence of a target nucleotide sequence in a polynucleotide. The method comprises hybridizing a first nucleotide sequence and a second nucleotide sequence to non-contiguous portions of a target nucleotide sequence, covalently attaching the first and second sequences when they are hybridized to the target sequence, and determining the presence of covalently attached first and second sequences. The presence of the covalently attached first and second sequences is related to the presence of the target nucleotide sequence. The invention may be applied to target nucleotide sequences in DNA or RNA. Specific target nucleotide sequences of interest will frequently be characteristic of particular microorganisms, viruses, viroids, or genetic characteristics, including genetic abnormalities.

Abstract: The invention concerns a construction to attach an acoustical microphone to the bell of a windinstrument. 
     The microphone is suspended with ringshaped elastics (2) in an external ring (3). Springy clamping elements (4) connect the ring to the bell. 
     The elastics are fixed between excisions of the rings (1), that are attached to the microphone, and the hollow cylinders (5) with a slit, that are slipped around cylindrical parts on external ring (3). 
     Due to the elastic attachment of the microphone, mechanical vibration transference from the bell to the microphone is practically ruled out. The elastics are interchangeable without splitting them. 
     This construction prevents damage to windinstruments, because it springs loose when overstrained mechanically and due to soft materials on the parts which are in direct contact with the bell. 
     This construction provides for a stable position of the microphone in relation to the bell, also after repeated mounting and dismounting.

Abstract: A process for transferring data via DMA between a system resource and a controller via switching logic. During a setup write transaction, the switching logic is set up to enable DMA data to be transferred between a particular system memory and a selected system resource. The setup write transaction also is used to initialize the DMA byte counter. During a subsequent write transaction, DMA pointer registers are initialized with appropriate starting addresses. The controller then transmits a DMA start code and the system resource responds by transmitting an acknowledge code. At that time, DMA data is transmitted between the controller and the system resource via the switching logic.

Abstract: A facsimile communication system makes a facsimile communication between a transmitting station and a receiving station. The transmitting station makes a call to the receiving station, detects a called station identification (CED) signal received from the receiving station, transmits a repeat (REP) signal to the receiving station when the called station identification (CED) signal is detected, detects whether or not the called station identification (CED) signal received from the receiving station stops within a predetermined time, and starts a facsimile transmission in conformance with a high-speed communication procedure the stop of the called station identification (CED) signal is detected within the predetermined time. The high-speed communication procedure employs a protocol which requires a time shorter than a protocol of a standard communication procedure which is in conformance with CCITT Recommendations. The receiving station transmits the called station identification (CED) signal when the call is received from the transmitting station, detects the repeat (REP) signal received from the transmitting station, and stops the transmission of the called station identification (CED) signal when the repeat signal (REP) stops.
