  • Patent number: 5446761
    Abstract: A decoder circuit (21) and method for providing an amplitude compensated signal by removing the undesired effect of amplitude modulation on a phase modulated signal. The decoder method is provided by demodulating a received inphase receive signal component (10) and quadrature receive signal component (12) of the phase modulated signal and outputting an amplitude varying signal (15) to a feedforward automatic gain control circuit that outputs an amplitude compensated signal (38). The feedforward automatic gain control circuit comprises a detector circuit (16), an offset bias circuit (32), a differencer circuit (30) and a gain control circuit (28).The detector circuit (16) outputs a DC signal (17) representing an amplitude of the inphase receive signal (10) and the quadrature receive signal (12). The offset bias circuit (32) provides a constant current bias (29) to the DC signal (17) thus creating a control signal 31.

  • Patent number: 5134694
    Abstract: Process for the management of address words which determines destination addresses for the switching of data on the basis of input address words of (M+N) bits. The process includes the following steps:on the basis of two input address words, separation of each one of these words into two fields of M and N bits respectivelycombination of these fields in accordance with a law of composition of non-commutative groups in order to deliver destination addresses emanating from the combination.The composition laws which are implemented necessitate only simple operations. Also a unit for the management of address words. This permits reduction of the addressing periods in searching for data, for example when they are stored in memory.

  • Patent number: 5126822
    Abstract: An IC is provided with supply pins extending beyond the chip's encapsulation. The location of the supply pins is chosen so as to minimize the length of the associated bonding wires. Moreover the supply pins are located next to each other so as to reduce the effective inductance of the associated bonding wires. Output pins connected with on-chip buffers are located next to the supply pins so as to reduce the length of the buffer's supply lines, giving rise to a further reduction is inductive parasitic effects.

  • Patent number: 5121063
    Abstract: An arrangement for determining on approximation the equivalent circuit diagram of an electrical or electronic element at high frequencies includes a measuring apparatus (4), to which the element to be represented as a two-port element (59) or a one-port element (1) is connected through connection members (2; 57, 58, 60) and which measures over a preselected frequency range the parameters of the stray matrix of the two-port element of the impedance or the reflection factor of the one-port element with the connection members. To the measuring apparatus (4) is connected an evaluation circuit (7), which corrects the measurement result by inclusion of two-port parameters of the connection member(s) determined before the measurement and which calculates for a preselected equivalent circuit diagram of the element from the corrected measurement result values of the equivalent circuit diagram elements by means of an optimization strategy.

  • Patent number: 5119101
    Abstract: When fewer than three of the satellites of a satellite global positioning system (GPS) such as NAVSTAR are visible to a user (15), the user cannot obtain independent positional information from the system. Since a satellite (11) in such a system is moving with respect to a user (15), its signals are received with a Doppler offset from their normal centre frequency and the frequency offset due to the satellite motion alone is calculable for a user at an approximate location from a given satellite. An additional Doppler frequency offset will result from any movement of the user. The magnitude of the additional frequency shift, in conjunction with the known speed (m) of the user, can be used to calculate the angle between the satellite motion (V.sub.1) and the user's motion and since the direction of the former is known, the user's heading from local North (N) can be calculated in instances where only one or two GPS satellites (11,12) are visible to a user.

  • Patent number: 5119102
    Abstract: Signals from a number of NAVSTAR global positioning system (GPS) satellites (11,12,13,14) are received by a receiver (16) in a vehicle (15) and a segment of the signals is stored in a memory (18) prior to retransmission by a transmitter (19). A base station (35) receives these transmissions from the mobile unit using a first receiver (36). The base station also receives signals directly from the NAVSTAR GPS satellites using a second receiver (38). A control and calculating apparatus (37) within the base station can determine the ephemeris (course) information for the satellites and can measure the transmission times or propagation delays of signals between the satellites and the vehicle and with this information the control and calculating apparatus can calculate the position of the vehicle unit.

  • Patent number: 5115507
    Abstract: The management of the priorities of access to a memory is characterized in that each request generator module (DP,GP) separately formulates the requests for access to a single word (DPREQ1, GPREQ1) and the requests for access to a plurality of words (DPREQN, GPREQN); differing priorities (REGA, REGB, REGC, REGD) may then be allocated (VALREG) to each type of request. Advantageously the requests for a single word are arbitrated by a first module which transmits a selected request to a second module.
