Title: Rake combiner/despreader apparatus
Inventor: HULBERT ANTHONY PETER
IPC: H04B1/707
Filed: 1994-11-26
Abstract: The Rake combiner/despreader apparatus comprises a shift register 2 for receiving channel estimates. The channel estimates are stored temporarily in two register banks 24, 22 which respectively store the real channel estimates and the imaginary channel estimates. The output of the register banks are applied to a respective adder/subtractor circuit 18, 26 and the respective channel estimates are included in the addition/subtraction under the control of control circuits 16 which compare the bit reference from the shift register to the output of a modulo N counter 4. The output of the counter 4 represents an index for the received bit corresponding to the position of the chip specified in a real or imaginary chip sequence which is applied to the shift register 2. The outputs from the respective adder/subtractor circuits 18, 26 are passed through a respective combiner circuit 28, 30 which combines the output with the real or imaginary channel samples respectively. The output of the combiner circuits 28, 30 are added together in an adder 32. An accumulator is provided for each bit position, and the output from the adder 32 is applied to an input of the particular accumulator 14, by a switch 38. The inputs to the accumulator 14 is formed by the output of the adder circuit 32 in combination with the selected output from the accumulator 14. The output of the accumulator 14 is selected by switch 36. When the last sample which can influence a particular bit has been processed, the contents of the accumulator 14 are read out and fed to subsequent circuitry for appropriate processing. <IMAGE>

Title: ABR traffic management in ATM networks
Inventor: CURTIS MARC SIMON
IPC: H04L12/56
Filed: 1995-06-05
Abstract: Connection control apparatus is provided for use in an ATM network to control ABR connections provided by the network, each such ABR connection having an agreed minimum transmission rate which it is permitted to exceed when there is spare capacity in the network. The apparatus includes: congestion detection means (32, 33) for determining the end-to-end delay experienced by ATM cells of each ABR connection as they pass through the network; and rate control means (30) connected to the said congestion detection means for detecting, based on the determined end-to-end delay, when one of the ABR channels is congested, and operative, upon such detection, to impose on the ABR connection concerned a maximum transmission rate that is higher than and dependent upon the said agreed minimum transmission rate for the connection concerned. Such apparatus can assist in achieving a fair allocation of bandwidth when congestion occurs in the network, and provides an effective way of detecting congestion without requiring processing at each intermediate node within the ATM network.
Patent GB-2292870-A (GB)
Title: Synchronization of digital telemetry
Inventor: DOYLE MARK R
IPC: E21B47/12
Filed: 1995-08-21
Abstract: A method of synchronizing a digital telemetry receiver to a digital telemetry transmitter (e.g. associated with oil well logging) is disclosed including the steps of initializing (42) the sampling period of the receiver, measuring the detection time of each signal event detected by the receiver relative to a time window based on the sampling period, accumulating statistics (58, 60, 62) representing the detection times of each of the events, and calculating (66) a refined sampling period based on a linear regression or least squares it of the actual detection time of each event. The signal received by the receiver includes an initial synchronization pattern followed by date representing the output of various sensors. The date modulated at the transmitter is A/D converted prior to sampling and decoding at the receiver (Fig. 1 not shown). The synchronizing method adjusts the sampling clock to correspond to the transmitter clock. The sync pattern may include contiguous or non-contiguous pulses. The detection of a signal event corresponds to exceedance of a predetermined threshold. <IMAGE>

Title: Pre-detent tactile feedback assembly for a fluid control valve
Inventor: DAHLGREN DEREK A
IPC: F16K11/07
Filed: 1995-09-22
Abstract: A pre-detent tactile feedback assembly includes an elastic member 51 seated within an annular groove 52 formed in the bore 31 of a plunger valve assembly. Preferably, this elastic member 51 is a garter type spring. When the plunger 27 is moved from an opened to a closed position, a portion 35 of the plunger 27 contacts the elastic member 51, urging the elastic member 51 outwardly into the groove 52. The additional force required to urge the elastic member 51 into the groove 52 provides a "feel" force to a control lever (17) (Fig. 1, not shown). Preferably, the groove 52 is positioned within the bore 31 so that this "feel" force is sensed just prior to actuation of an associated detent assembly (21). <IMAGE>
