Abstract:
The invention relates to an improved method for fabricating the amplification gap of an avalanche particle detector in which two parallel electrodes are spaced apart by dielectric spacer elements. A foil including a bulk layer made of dielectric material sandwiched by two mutually parallel metallic electrodes is provided, and holes are formed in one of the metallic layers by means of photolithography. The amplification gap is then formed in the bulk layer by means of carefully controlled etching of the bulk material through the holes formed in one of the metallic layers. The invention not only provides a simplified fabrication process, but also results in a detector with enhanced spatial and energy resolution.

PROBLEM TO BE SOLVED: To generate a mobile object for providing trade-off between superior set point voltage monitoring and cancellation of disturbance operated upon an adjustment loop. SOLUTION: The mobile object 1 includes: a variable load impedance Z and a rectifier 5 connected in parallel to a terminal of an antenna 3; and an adjustment loop for a terminal voltage of the load impedance Z connected between an output of the rectifier 5 and a control terminal of the load impedance Z. The adjustment loop includes, in series, a means 7 for determining a difference between a set point voltage and an output voltage of the rectifier 5; an analog-to-digital (A/D) converter 8 of one bit; and an integrator type command means 9. The command means 9 includes a gain control input M connected to an output of the gain control means 10 for specifying gain control rules corresponding to the difference. A demodulation means 17 is connected to an output of the converter 8. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for charging a battery using an intermittent power source which is easily mounted and has a long battery life. SOLUTION: An autonomous system includes the intermittent power source 2 supplying a direct current I 1 . The method involves at least one stage of charging with a pulse current managed by a charging control circuit, and a supercapacitor 6 is connected in parallel with the battery 1 and the power source 2 respectively via a first electronic switch 4 and a second electronic switch 5. Charging the battery includes pulse current charging managed by a control circuit 3. During a current pulse, the amplitude of the current pulse and the amplitude of the voltage increase at the terminals 1 of the battery are measured. The dynamic internal resistance of the battery is determined by the amplitudes. A maximum acceptable current threshold is determined according to a predetermined maximum voltage threshold, the dynamic internal resistance and the no-load voltage at the battery terminals. At the next current stage, the value of the charging current is limited by controlling the closing time of the second electronic switch 5. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
The invention concerns a device for air/water extraction by semi-humid electrostatic collection, comprising a chamber (7) containing a discharge electrode (1) for generating an ion flow from an ionized gas accumulation surrounding the discharge electrode (1) and a counter-electrode (2), an inlet (3) for mixing air and aerosol to be extracted which contains liquid or solid particles, a steam supply tube (8) and an outlet (4) for the cleansed air. The invention is characterized in that the device enables steam to be introduce the steam supply tube (8) in the gap between the discharge electrode (1) and the counter-electrode (2) so as to form a steam sheath (10) enclosing the discharge electrode over its entire length, such that the treated air is not steam-saturated.
