Abstract: A bar code system includes a bar code label and a bar code reader. The bar code label has a bar code symbol (144A) represented by a background and stripes of at least two different types. The background and the stripes of the two different types provide different reflectivities respectively. The bar code reader applies light to the bar code label. A portion of the applied light is reflected at the bar code label, and the reflected portion of the light forms return light. The bar code reader receives the return light, and converts the return light into a corresponding electric signal. In the bar code reader, a level of the electric signal is compared with a plurality of predetermined different reference levels to detect contents of the bar code symbol.

Abstract: A fiber optic connector in which first and second optical fibers are aligned at a fiber interface of the connector. The first optical fiber (53) has a beveled angle end face, and the second optical fiber (80) has a complementary beveled angle end face. Abutting connector members (42,44) are joined in a connector enclosure (20) which enables the respective fiber end faces to abut at an angle at the fiber interface. The respective fiber end faces are joined at a vertical aligned position for the connector, also at a horizontal aligned position for the connector. Suitable alignment means provided on the connector members enable alignment of the fiber end faces at the fiber interface. In a fixed aligned position of the assembled connector, the respective fiber end faces are held in abutting and full engagement at the fiber interface, in which the vertical aligned position of the optical fibers in the connector is coincident with the horizontal aligned position thereof.

Abstract: In an anti-lock braking system, when wheel parameters including slip represent an incipient wheel lock-up condition normally calling for a release of brake pressure during a pressure apply mode of an anti-lock braking cycle and the duration of the pressure apply mode (t apply)is less than a predetermined threshold (t threshold) representing an abnormal rapid cycling of the brake pressure, the wheel slip threshold S threshold  representing an incipient wheel lock-up condition is increased, the rate of increase in brake pressure during the brake pressure apply mode is set to a high level and the pressure apply mode is continued during which the wheel brake pressure is ramped at the increased rate. These steps are repeated while the wheel parameters represent an incipient wheel lock-up condition normally calling for a release of brake pressure until the time of the pressure apply mode equals the predetermined threshold representing a normal brake pressure cycling period. At this time, the rate of pressure increase during the apply mode is returned to normal and the system is set to a release mode wherein the brake pressure is released. The slip threshold S threshold  is thereby adjusted to establish normal brake pressure cycling.

Abstract: The invention relates to the positioning of pairs of headed workpieces, particularly poppet valves for internal combustion engines in centreless grinding. The essential features of the invention are that axial stops (8; 9) adjustable from outside are arranged between two workpieces lying in mirror image in the grinding gap with the stem ends directed to the inside, that holding devices acting axially from the outside act on the workpieces, and that the holding devices are equipped with nozzles (17) for applying suction and pressure or with gripper claws and are mounted on controlled working pistons (18). Thus two workpieces can at the same time be precisely positioned and produced in a time-saving and careful manner and with high quality and can also be fed into position and discharged. <IMAGE>

Abstract: A brushless motor is provided with a rigid resin member that faces one end of the drive shaft with a predetermined gap therebetween. The rigid member is positioned to be struck by the end of the drive shaft when the drive shaft vibrates. The impact of the collision is absorbed by the elastic deformation of a resilient member that supports the rigid member. This prevents noise from being generated by vibrations of the drive shaft.
