Abstract: A compact, hand held carpet and upholstery extractor nozzle is provided having a pair of air turbine powered vertical axis rotary scrub brushes located adjacent the extractor nozzle. The turbine has at least one ambient air inlet and an outlet that communicates with a suction tube extending from the extractor nozzle. A compact gear reduction operatively connects the air turbine to the scrub brushes. A turbine outlet baffle is preferably provided that extends from an upstream edge of the turbine outlet, into the suction tube and over and beyond the turbine outlet to direct air, liquid and debris flowing through the suction tube over and beyond the turbine outlet opening. A downstream end of the baffle is open and suction openings pass through the baffle, for providing fluid communication between the suction tube and the turbine outlet opening. A raised floor is preferably located in the suction tube upstream of the baffle that directs the flow of air, liquid and debris in the suction tube substantially past the suction openings. A shoulder is preferably provided on each side of the baffle that extends generally longitudinally in the suction tube below the suction openings. The upstream ends of these shoulders curve upward until the shoulders are substantially flush with raised floor. With this construction, any drops of liquid adhering to the raised floor and traveling toward the baffle, will adhere to the shoulders and be directed below the suction openings.

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 an d 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 rejectio n 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).</SDOAB >

Thus a voltage boosting circuit which provides for a boosted voltage V PP at an output node, from a supply voltage V DD, includes a precharge transistor element responsive to a precharge clock signal for transferring the supply voltage V  DD to a boost node for precharging the boost node to the full supply voltage V DD. The circuit further includes a capacitive element connected between the boost node and a pump node, the capacitive element pumping the boost node in response to a pump voltage signal applied to the pump node; and a switching element connected between the boost node and the output node, for transferring charge from the capacitive element to the output node to provide the boosted voltage V PP. In particular the precharge transistor element is an PMOS transistor. Furthermore in order to prevent latch-up of the PMOS devices, a switching circuit is provided to maintain the substrate at the highest voltage in the circuit.

IPC: G01S1/00
Filed: 1997-06-03
Granted: 2005-02-01
Abstract: The invention concerns receivers for positioning by satellites (GPS). To improve the measurement reliability, satellites supplying defective measurements, i.e. measurements diverging with respect to the measurements supplied by the other satellites of the constellation used at a given moment, are not considered in a position measurement. The invention proposes a solution to re-compute the position more rapidly by eliminating data from a defective satellite: the means for computing position X vector based on n satellites comprise an iterative process with n steps, the j<th> step calling on the j<th> satellite; a position X' is re-computed using only n-1 satellites based on n steps already computed, by adding a (n+1)<th> iteration step, using the defective satellite measurements of rank m, this last step being slightly different from the previous ones and the difference being such that the computation result after this (n+1)<th> step is identical to that which would result from a iteration with n-1 steps excluding the divergent rank m satellite.
