Abstract: A structure and method for circularizing and collimating incident light involves a substrate having first and second opposing surfaces, a first anamorphic surface positioned on the first surface and a second anamorphic microlens positioned on the second surface, the first and second surfaces being separated by a distance defined by the distance required for the first anamorphic microlens to circularize the incident light. A single microlens structure used to circularize and collimate incident light is manufactured by identifying aligned portions on opposing surfaces of a substrate, and forming microlenses on each of the aligned portions of the opposing substrate surfaces identified. The microlenses formed on the opposing substrate surfaces are fabricated from a high-index material such as GaP.

Abstract: A system and method for achieving alignment of a mask and substrate focuses a first image (e.g., a reticle) on a first position of a first substrate surface, and determines whether the first position is aligned with a second position on an opposing second substrate surface based on a second image formed based on light from a micro-optical device located on the second surface which collects light from a first image focused thereon. To determine whether the first and second positions are aligned, the first image and the second image are projected on an image plane and compared, the first and second positions being aligned when the first image and the second image are coincident on the image plane. A mask and/or alignment pattern may be formed on the opposing substrate surfaces, and used to generate aligned optics on those surfaces. As such, precise alignment between optics on opposing surfaces of a substrate can be achieved.

Abstract: Novel thiazolyl peptide antibiotic compounds, including nocathiacin I, II and III, are disclosed. Also, novel microorganism ATCC-202099 is disclosed.

Abstract: A computer-based system is disclosed for monitoring and controlling the takeoff and landing of aircraft from an airport that is large enough to require the services that are routinely associated with operations at a control tower. Individual air traffic controllers continue to have the responsibility for monitoring aircraft that are within the operations zone of their tower. But when responsibility for a given aircraft is to be transferred from one controller to another, an icon in each of two separate arrays on a computer screen is sequentially selected by the transferring controller. The first selected icon represents the aircraft; the second selected icon represents the new controller. Other icons give certain control functions (e.g.

Abstract: In accordance with the present invention, a BOE-corrected, off-axis image forming apparatus is disclosed. The apparatus has a first stage with a primary reflective element disposed to reflect light incident from an entrance pupil of the apparatus and form a real image at an intermediate image plane, and a second stage located off-axis with respect to the first stage. The second stage is defined by a secondary reflective and/or refractive assembly which re-images light from the intermediate image plane to a final image plane. A binary optical element (BOE), which has higher-order optical characteristics for providing aspheric correction but extremely low optical power, is provided in one of the stages for correcting aberrations introduced by the other optical elements in the apparatus. The BOE contributes no more than about 3% of the optical power provided by the stage which contains the BOE.

Abstract: A tire pressure monitoring system for vehicles characterized by a plurality of tire pressure sensors for sensing pneumatic pressure interiorly of the tire, a plurality of transmitters connected responsively with the tire pressure sensors and adapted to be energized when any one of the tire pressure sensors indicates a low pneumatic pressure within one of the tires; at least one receiver responsively disposed with respect to the transmitters so as to be energized by a transmitter when the transmitter is energized by the tire pressure sensor and a warning means, including a buzzer and a light, disposed in the operator's cab for conveying the warning to the operator when a low tire pressure is sensed, the warning means being electrically connected with the receiver, or receivers, so as to be energized when the receivers are energize.

Abstract: A scraper mechanism for the disk gangs of disk harrows and embodying a series of flexible scraper arms, one for each disk, which depend from a common scraper support and carry scraper blades at their lower ends. The upper ends of the scraper arms are turned laterally and provide short attachment sections of wide angle concavo-convex configuration. A clamping bolt extends through the apex of each section and the support and, upon tightening thereof progressively flattens the section against the support and thus swings the depending portion of the scraper arm in the direction of the respective disk for regulating the pressure of the scraper blade against the disk. Means are provided for shifting the position of the common scraper support so that collective adjustment of the various scraper blades may be effected.
