Abstract: Guardrail, guardrail terminal, and support post designs that improve control of a vehicle during collisions are described. The disclosed designs also reduce the likelihood of intrusion into vehicle systems and the occupant compartment(s). Embodiments include folding and/or flattening of the guardrail and controlling the folded and flattened guardrail to avoid intrusion into the vehicle. Other embodiments include containing the guardrail in an impact head of a guardrail terminal, which also avoids vehicle intrusion.

Abstract: Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

Abstract: A continuous liquid ejector includes a structure including a wall. A portion of the wall defines a nozzle having a first fluidic resistance R1. A first liquid feed channel is in fluid communication with the nozzle. The first liquid feed channel has a second fluidic resistance R2. A first drop forming mechanism is associated with the first liquid feed channel. A second liquid feed channel is in fluid communication with the nozzle. The second liquid feed channel has a third fluidic resistance R3. The first fluidic resistance R1 is less than the second fluidic resistance R2 plus the third fluid resistance R3 (R1<(R2+R3)). A second drop forming mechanism associated with the second liquid feed channel.

Abstract: A flexible fiber optic illuminator 10 for inspecting an interior space, comprises a thin fiber optic element 12 composed of a plurality of optic fibers 20 arranged in at least one substantially planar layer having front and back sides 32,34. Thin stiffner members 24,26 are arranged adjacent to the optic fibers 20 to provide reinforcement. First and second layers 28,30 of adhesive material having adhering means on one side only, are fixedly adhered to the back and front sides of the planar layer 22. A protective jacket 36 for optic fibers 20 and stiffner members 24,26 is therefore defined by first and second adhesive layers 28,30. A light source 14 coupled to the fiber optic element 12 is provided for illuminating the optic fibers 20.
