Title: Magnetic flux detector and detection method
Inventor: SEKIYA SHIGENOBU
IPC: F16D65/18
Filed: 2002-03-04
Granted: 2008-10-14
Abstract: A magnetic flux detector comprises a core member 12 and an armature member 11, and the core member 12 generates a magnetic flux by an exciting coil 13 when the exciting coil receives an excitation current controlled by an excitation current controller 30. The magnetic flux detector further comprises a search coil 14, which is provided in a magnetic path for the magnetic flux, and a magnetic flux calculator 40, which determines the magnitude of the magnetic flux by measuring an electromotive force induced in the search coil 14 by a change in the magnetic flux. The excitation current controller 30 controls the excitation current to increase from zero to a predetermined current value during a first predetermined time period T1 and then to decrease from the predetermined current value to zero during a second predetermined time period T2, and the magnetic flux calculator 40 determines the magnitude of the magnetic flux based on the difference between the increasing electromotive force integral value which is calculated by integrating the electromotive force induced in said search coil 14 during the first predetermined time period T1 and the decreasing electromotive force integral value which is calculated by integrating the electromotive force induced in the search coil 14 during the second predetermined time period T2.

Inventor: BLAIS JEAN-FRANCOIS
IPC: C02F1/52
Filed: 2000-07-27
Granted: 2010-02-16
Abstract: The invention relates to a hybrid biological and chemical method for decontaminating sludge containing heavy metals and pathogenic microorganisms, consisting of the following steps: the sludge is mixed with an acidic leaching solution in order to acidify the sludge with a pH which is low enough to solubilize the majority of the heavy metals and to destroy most of the pathogenic microorganisms but which is also high enough to minimize the solubilization of fertilizing elements; oxidation-reduction of more than +400 mv is maintained, liquid-solid separation occurs in order to obtain a solid fraction comprising decontaminated acidic sludge and a liquid fraction comprising heavy metals which are dissolved in a leaching solution; the sludge is neutralized: and neturalized decontaminated sludge is recovered, whereby the fertilizing elements contained therein, i.e. carbon, nitrogen and phosphorus, remain substantially unchanged in relation to the initially contaminated sludge.

Granted: 2011-06-28
Abstract: A method and system for converting the output of a communications port (210) (e.g., a serial port or a USB port) into video signals (120) representing the output of a terminal. The system is interposed between the communications port and a set of two or more inputs to a keyboard (122), video and a mouse (124) switch. Upon receiving characters from the communications port (210), the system interprets the characters as terminal emulation commands and internally generates a representation of what a resulting terminal screen would look like. From that internal (digital) representation, the system produces analog outputs (20) representing the terminal screen. The analog outputs are applied to the video input of the KVM switch such that the terminal output can be viewed on the monitor attached to the KVM switch (74).
