Patent CA-2232124-A1 (CA)
Inventor: POWELL IAN
IPC: G01B11/04
Filed: 1998-03-16
Abstract: An optical device for measuring the length of a surface that has an undulating specular appearance. The device includes a beam delivery unit that superimposes a pair of laser beams onto a moving surface for producing an interference pattern having straight-line fringes on it and a light collector assembly that captures radiation reflected from different parts along the surface and directs the radiation to a detector. One particular beam delivery unit creates two interfering beams by using refracting prisms to intercept and redirect half of an elliptically shaped laser beam leaving the other half as the second beam. The collector assembly can have a variety of configurations and acts like a bucket collecting as much of the reflected radiation as possible. In order to accomplish this, the numerical aperture in the object space of the collector assembly is made greater than 0.5. In one embodiment, the collector assembly includes a plano-convex lens to collect narrow to moderate angle radiation, and the combination of a concave annular reflector and a partially reflective convex surface of the plano-convex lens to collect the moderate to wide angle radiation reflected from the moving surface to be measured. In other embodiments, Fresnel , aspheric or high refractive index lenses are used to collect the radiation reflected from the surface.

Inventor: MOELLER LOTHAR BENEDICT ERHARD
IPC: H04B10/2507
Filed: 1998-09-28
Abstract: The present invention relates generally to the field of optical communications and particularly to optical communication techniques which compensate for dispersionsuch as that in optical fibers.   Compensation of optical dispersion is achieved with a polarisation beam splitter with first, second and third ports, a dispersion compensation fiber, a first return means that changes the mode of polarisation of a returned signal and a second return means. One end of the dispersion compensation means is connected to the third port of the polarisation beam splitter, the other end is connected to the first return means. The second return means is connected with the second port of the polarisation beam splitter, while the first port of the polarisation beam splitter forms input and output. As the signal passes through the disperion compensating fiber four times, the length of the dispersion compensating fiber can be greatly reduced.

Title: Method and apparatus for verifying the position of a motor driven machine element
Inventor: CATANZARO JOHN C
IPC: G05B19/4062
Filed: 1998-10-16
Abstract: A method and apparatus for verification of the linear position of a machine element driven by a motor is provided. The actual position of the element is detected and compared to an expected position. When the two positions differ from each other by more than a predetermined tolerance value for a predetermined amount of time, an error signal is generated which deactivates the motor and generates an alarm for the machine operator. Preferably, the linear position of the axis is detected by a transducer and the expected position is determined by detecting the rotary position of the motor through the use of a resolver, which is then converted to a linear equivalent through the use of the gearing ratio. The method and apparatus can detect faulty machine conditions and thereby prevent machine malfunction and/or machine damage. Preferably, the method and apparatus are used to verify the position of machine elements in an injection molding machine.

Title: Pressure pulse generator for measurement-while-drilling systems which produces high signal strength and exhibits high resistance to jamming
Inventor: MORIARTY KEITH A
IPC: E21B47/18
Filed: 1998-10-29
Abstract: A system is disclosed for generating and transmitting data signals to the surface of the earth while drilling a borehole, the system operating by generating pressure pulses in the drilling fluid filling the drill string. The system is designed to maximize signal strength while minimizing the probability of jamming by drilling fluid particulates. The system uses a rotary valve modulator consisting of a stator with flow orifices through which drilling fluid flows, and a rotor which rotates with respect to the stator thereby opening and restricting flow through the orifices and thereby generating pressure pulses. The flow orifices with the stator in a "closed" position are configured to reduce jamming, and to simultaneously minimize flow area in order to maximize signal strength. This is accomplished by imparting a shear to the fluid flow through the modulator, and minimizing the aspect ratio and maximizing the minimum principal dimension of the closed flow area. A preferred embodiment and three alternate embodiments of the modulator are disclosed.

IPC: G01S7/526
Filed: 1997-05-23
Abstract: Acquired signals representing samples of propagating wavefields are processed using space-time linked variable methods (Figure 5A) to form images having better definition and resolution than may be obtained by conventional methods.  Frequencies accessed include those anticipated as well as some apparently beyond those deemed feasible according to the Nyquist criteria as well as those present in the wavefield source. The signals and physical features may be obtained in tomography (medical CT scans), echo location (radar or sonar) or seismic imaging for example. Signals are processed (Figure 8) maintaining interrelation of the linked variables of time and space, rather than following the conventionally accepted current techniques which treat the time and space variables independently. Definition and resolution of images are obtained beyond those normally considered possible with earlier techniques by understanding and correctly interpreting the information content of a sampled wavefield. Data acquisition speed can be greatly increased, while acquisition costs are also reduced since the methods described require less data and use such data as available more effectively.
