IPC: E01H1/08
Filed: 2000-07-28
Abstract: A closed-loop Regenerative® air sweeper is provided. The sweeper includes a "dustless" mechanism having first and second chambers, into the first chamber of which is directed a portion of the air stream from a pressure conduit associated with a pickup head of the sweeper. Particles of debris are separated by cyclone separators and thereafter by membrane filters after which substantially clean air is discharged to atmosphere. Air entrained particles separated by the cyclone separators and the cartridge filters are returned to a vacuum side of the pickup head thereby maintaining substantially closed-loop air flow of the sweeper. Clean air is controllably exhausted to atmosphere by flue vanes which can be selectively moved under pressure differential sensing means associated with the cyclone separator. The pressure in the two air chambers is also sensed with the read-out thereof being in an instrument panel to permit an operator to monitor and diagnose the system. Pulses of high pressure air are utilized to clean the membrane filter and a pop-off valve serves as an emergency vent to atmosphere under undesired high pressure within the second chamber of the housing. An extremely important aspect of the present invention is that achieved by creating and maintaining a substantially negative pressure at and across the pickup head. The latter is achieved by assuring that the air drawn into the pickup head is approximately a nominal ten percent (10%) and the clean air discharged to atmosphere is maintained at substantially the same nominal ten percent (10%) through appropriately operating a valve under the control of a pressure differential sensor which measures pressure drop across the cyclone separators.

IPC: G01C19/66
Filed: 2000-11-07
Abstract: A ring laser gyro wherein a first and a second laser beam propagate with propagating directions different with-each other comprises electrode areas on an optical waveguide configuring the ring laser and controls an current injected or a voltage applied to the electrode areas, wherein the oscillating frequencies of the first and second laser beams are different from each other, thereby causing an increase and a decrease in the beat frequency enabling to detect the direction and the speed of a rotation at the same time. With regards to a method for detecting a rotation, the anode of the laser gyro is connected to an operational amplifier. Since the signal outputted from the operational amplifier has a frequency corresponding to the angular speed, it is converted into the voltage by a frequency-voltage conversion circuit so as to detect a rotation. This same method can be used for other types of gyros such as a semiconductor laser gyro, a gas lager gyro and the like.

Abstract: The present invention provides a strictly non-blocking WDM cross-connect that utilizes a relatively small number of wavelength interchangers. In accordance with one embodiment, the WDM cross-connect utilizes n1k1 wavelength interchangers, where n1 is an integer equal to the number of wavelengths carried on an input optical fiber associated with the WDM cross-connect and k1 is the total number of input optical fibers to the WDM cross-connect. Each of the wavelength interchangers is connected to exactly one input port of the fabric and each input port of the fabric is connected to exactly one wavelength interchanges. The input optical fibers of the WDM cross-connect are connected to k1 optical switches of the cross-connect that separate out the n1 wavelengths onto n1 optical fibers, which are input to respective wavelength interchangers. Therefore, each wavelength interchanges receives exactly n1 optical fibers. The fabric has output ports that are connected to k2 output optical fibers, where k2 is an integer equal to the number of output optical fibers that are connected to the output ports of the fabric. In accordance with another embodiment of the present invention, the WDM cross-connect comprises two fabrics and one or more wavelength interchangers that interconnect the fabrics. The cross-connect in accordance with this embodiment can be rendered strictly non-blocking by utilizing a number of wavelength interchangers equal to (k1 + k2) - 1, where k1 and k2 correspond to the number of input and output optical fibers, respectively, of the WDM cross-connect. In accordance with both of these embodiments, the number of input and output optical fibers of the strictly non-blocking WDM cross-connect can be unequal.
