Title: Circuit module for a phased array radar
Inventor: DEAN MICHAEL
IPC: G01S7/02
Filed: 1995-07-07
Abstract: A circuit module for a phased array radar (10) incorporates radar frequency (RF) mixers (54a, 54b) connected to an RF splitter/combiner (52) and to in-phase and quadrature RF reference signals. The RF mixers (54a, 54b) are also connected to intermediate frequency (IF) processing circuitry (60 to 68) providing for phase control of RF signals and IF reference signals. In transmission mode, the RF mixer (54a, 54b) receive phase-controlled, digitally synthesised IF signals from clock-activated generators (68a, 68b). Their outputs are combined at the RF splitter/combiner (52) to provide single sideband upconversion of the phase-controlled IF signals. In reception mode, the RF splitter/combiner (52) and the RF mixers (54a, 54b) act as an image rejection mixer circuit in which the phase-controlled IF signals are local oscillator signals. Beamforming is carried out by computer control of the IF phase together with, in the case of reception, analogue or digital summation of output signals from an array of modules (12).

Patent CA-2228493-A1 (CA)
Inventor: TANAKA KIYOTO
IPC: G06F7/72
Filed: 1998-02-02
Abstract: A scheme for carrying out modular calculations which is capable of carrying out modular calculations using redundant binary calculation even when a number of bits of the mantissa (dividend) is larger than a number of bits of the modulus (divisor). In this scheme, the divisor c in the divisor register is left shifted by (i-j) digits when a number of digits j of the divisor c is less than a number of digits i that can be stored in the divisor register, and the modular reduction a mod c is calculated up to (i-j)-th decimal place using the dividend a and the left shifted divisor c. Alternatively, the divisor c given in h-ary notation in the divisor register is left shifted by (i-j) digits when a number of digits j of the divisor c is less than a number of digits i that can be stored in the divisor register, while the dividend a given in h-ary notation in the dividend register is left shifted by (k-~) digits when a number of digits ~ of the dividend a is less than a number of digits k that can be stored in the dividend register, where k ~ i. Then, the modular reduction a mod c is calculated up to a digit of [(k-~)-(i-j)]-th power of h using the left shifted dividend a and the left shifted divisor c to obtain a remainder, and this remainder is right shifted by (k-~) digits.

Title: Membrane air dryer with scheme to reduce air lost as sweep air
Inventor: CUNKELMAN BRIAN L
IPC: B01D53/26
Filed: 1999-01-20
Abstract: A control system reduces the amount of gas lost as sweep gas from a membrane gas dryer. The membrane gas dryer is of the type that features an inlet end that receives moisture laden gas from a compressor, an outlet end from which dried gas is discharged to a pneumatic component and a drain port from which permeate sweep gas inclusive of permeate water vapor is expelled from the gas dryer. The control system includes a purge valve that is connected to the drain port of the gas dryer and a mechanism that controls the purge valve. The purge valve has a pilot port that responds to pressure by closing the purge valve thereby preventing the permeate sweep gas from exhausting to atmosphere through the drain port. The mechanism controls the purge valve such that (i) when the compressor is unloaded, the mechanism allows flow of the dried gas from the pneumatic component to pressurize the pilot port thereby closing the purge valve and preventing the permeate sweep gas from exhausting to atmosphere and (ii) when the compressor is loaded, the mechanism vents the pilot port to atmosphere thereby opening the purge valve and allowing the permeate sweep gas to exhaust to atmosphere via the drain port of the membrane gas dryer.
