Patent EP-0562521-A2 (EP)
Inventor: HAYASHI MISHIO
IPC: G01R23/15
Filed: 1993-03-22
Abstract: Based on a desired center frequency and a frequency resolution for a signal to be measured which are entered via an operator section (11), a micro-CPU (12) calculates the frequency dividing number (k), a preset value (M+P) and a center value (Nc) for the signal to be measured. The frequency dividing number is set in a frequency divider (15), which frequency divides the signal to be measured and provides the frequency-divided output to a continuous period-to-voltage converter (10). The continuous period-to-voltage converter counts clock pulses occurring in each frequency-divided period, measures the difference between fractions of time from both the beginning and the end of the frequency-divided period to the generation of the next clock pulses, respectively, and outputs, as a voltage corresponding to the frequency-divided period, the sum of a voltage corresponding to a predetermined number of consecutive low-order bits of a binary value, obtained by adding the preset value to the pulse count value, and the fractional time difference. A subtractor (19) is supplied with a voltage corresponding to the frequency-divided period and a voltage corresponding to the center value and outputs the voltage difference as a frequency-divided period deviation, and the micro-CPU calculates a frequency deviation of the measured signal from the center frequency on the basis of the frequency-divided period deviation.

Abstract: The invention relates to a circuit arrangement for compensating for voltage drops on supply lines (supply leads) and for reducing the harmonics of the current, in which circuit arrangement terminals (0, P1) of an AC source (PS) are connected to the input of an electronic voltage and/or current compensator (ELDC) via a supply network (ZL) which represents an impedance consisting of inductors (inductances) (L0, L1, L2, L3) and resistors (R0, R1, R2, R3), a load impedance (LD) being connected to the output of the compensator (ELDC). The invention essentially comprises a primary winding or windings (PR) of a transformer or transformers (TR) being inserted between the phase output or outputs of the supply network (ZL) and the load impedance (LD), a supply lead or supply leads of the (individual) secondary winding or windings (SR) being connected to a phase output or phase outputs (R, Y, B) of the supply network (ZL) and another supply lead or other supply leads of the secondary winding or windings being connected via a single-phase switching matrix, or single-phase switching matrices (SM1) to the neutral point (0) of the supply network (ZL), or being connected to one another by a three-phase switching matrix (SM3). <IMAGE>

Abstract: A halftone screen generator, halftone screen and method for making the halftone screen are disclosed. The halftone screen has a screen angle and rulings that define the theoretical centers of gravity of the halftone dots. The actual centers of gravity of the halftone dots are displaced from the theoretical centers of gravity by the length and angle of random phase vectors. In one embodiment, the positional displacement of the centers of gravity of the dots is dot size dependent in an inverse relationship. The shift in dot centers of gravity away from the theoretical centers of gravity defined by the halftone screen effectively breaks up screen "patterning" and avoids objectionable halftone "graininess".

Abstract: A reinforced catheter sensor probe (12) for intravascular use includes an aramid strand (32) that extends along the length of electromagnetic conduits and is bonded thereto. A greater than ten fold increase in tensile strength is thereby achieved. Additionally, the inherent strength of flexibility of the reinforcing strand (32) ensures that a positive interconnection with the distal end (14) of the sensor probe is maintained in the event the sensor probe is subjected to loads that cause its relatively more fragile components to sever. A protective, strain relieving introducer catheter (40) is also provided to substantially prevent kinking and breakage of the sensor probe where the introducer catheter bends.

Filed: 1995-08-11
Abstract: In a DS/CDMA receiver, each of first and second receiving units (211 and 221) receives a DS/CDMA signal as a received signal. First and second adaptive interference cancellers (212 + 213, 222 + 223) are connected to the first and the second receiving units, respectively. Each of the adaptive interference cancellers cancels an interference on the received signal. Connected to the first and the second receiving units and to the first and the second adaptive interference cancellers, a single interference canceller control circuit (204) controls the first and the second adaptive interference cancellers in common. An all output combiner (201) combines all of output signals of the first and the second adaptive interference cancellers. Preferably, each of the adaptive interference cancellers has an adaptive filter (212 or 222) to cancel the interference with respect to all other stations by adaptively making its tap coefficients orthogonal to spreading codes of the all other stations. Each of the adaptive interference cancellers further has a differential detection circuit (213 or 223) to compensate for phase fluctuation of an output signal of the adaptive filter. The single interference canceller control circuit may control the adaptive interference cancellers in common on the basis of best quality control information relating to one of the received signals of the first and the second receiving units that has a best signal quality.
