Abstract: A dense wavelength multiplexer/demultiplexer ("DWDM") (10) for us in optical communication systems includes a multiplex optical waveguide (14) propagating a plurality of optical channels (.eta.iest;1-n) of a select channel spacing multiplexed as a single optical signal within a select near infrared wavelength range. a collimating/focusing optic (18) is optically coupled to the multiplexed optical waveguide at a select focal length. A reflective echelle grating (20) is optically coupled to the collimating/focusing optic (18). The echelle grating (20) has a groove spacing (d) and blaze angle (.theta. b) providing a channel spacing (d) of the multiplexed optical signal (.eta.1-n) at the select focal length for a select order of diffraction. A linear array of single channel waveguides (16), each propagating a single channel within the near infrared wavelength range is optically coupled to the collimating/focusing optic. Each optical single channel waveguide (16) has a center and a propagating end and the propagating ends are spaced the focal length from the collimating/focusing optic and the centers of adjacent demultiplexed waveguides are spaced the select channel spacing (D). A fiber pigtail harness is used to connect the multiplexer which works in a Littrow configuration.

Title: Method and apparatus for measuring vehicle wheel roll radius
Inventor: JACKSON DAVID A
IPC: G01B11/00
Filed: 2000-09-26
Abstract: A method and apparatus are provided for determining a roll radius of a vehicle wheel for use in alignment and other diagnostic or maintenance operations. An optically scannable target is attached to a wheel of the vehicle. A first position measurement is made using a machine vision system, such as a three-dimensional aligner. The vehicle is rolled a short distance and a second position measurement is made. The linear and angular differences of the first and second position measurements are used to compute and store a roll radius value. Alignment values resulting from alignment of the motor vehicle are modified based on the roll radius value. A plane angle value may also be created and stored for use in adjusting the alignment values.

Abstract: An incremental positioner is disclosed. In one embodiment, the incremental positioner includes a motor (208), a drive shaft (210), a motion converter a nd a rack (214). The motion converter engages the rack (214) and, impelled by t he motor (208) and drive shaft (210), causes the rack (214) to move. The motion  converter transmits and converts the continuous rotary motion of the motor (208) to a linear intermittent motion of the rack (214). To generate such intermittent motion, the motion converter is physically configured so that even though the motion converter is in constant motion, it urges the rack (214) to move on a periodic basis. In other words, during each revolution of  the motion converter, the rack (214) dwells (i.e., does not move) during a second portion of the cycle. Each time the rack (214) advances, it does so b y a characteristic incremental distance.

Title: Methods and compositions for modulating er-stress-induced cholesterol accumulation
Inventor: AUSTIN RICHARD CARL
IPC: G01N33/92
Filed: 2000-11-16
Abstract: The present invention provides methods for preventing the accumulation of cholesterol/triglycerides within mammalian cells. The present methods are based upon the surprising discovery that ER stress in a cell leads to cholesterol/triglyceride accumulation within the cell, which cholesterol/triglyceride accumulation is often a causative factor in the development of any of a number of conditions or diseases, such as atherosclerosis. The ER stress can be the result of any of a variety of causes, including homocysteine, viral infection, and hypoxia. Accordingly, counteracting the progression or the severity of ER stress can be used to inhibit the accumulation of cholesterol/triglycerides in said cell, thereby preventing or lessening the severity of any of a number of cholesterol-related diseases or conditions, e.g., atherosclerosis. In addition, the presence of ER  stress in a cell can be used to diagnose a cholesterol associated disease, or to predict the propensity of a mammal to develop a disease.

Title: Digital phase shifter
Inventor: GOETTING F ERICH
IPC: H04L7/00
Filed: 2001-10-05
Abstract: After a delay lock loop (300) synchronizes a reference clock signal with a skewed clock signal (REF-CLK), a digital phase shifter (350) can be used to shift the skewed clock signal (S-CLK) by a small amount with respect to the reference clock signal. The tap/trim settings of a delay line (310) in the main path of the delay lock loop can be transmitted to the digital phase shifter, thereby informing the digital phase shifter of the period of the reference clock signal. In response, the digital phase shifter provides a phase control signal that introduces a delay to either the reference clock signal or the skew clock signal. The phase control signal is proportional to  a predetermined fraction of the period of the reference clock signal.
