Title: Retro-reflective system for increasing safety of a railroad crossing, and associated method
Inventor: BROWN CURT M
IPC: E01F9/04
Filed: 2005-12-19
Granted: 2010-05-11
Abstract: A retro-reflective system for increasing the safety of a railroad crossing includes at least one railroad crossing panel. A sealer is applied to a prepared surface of the railroad crossing panel. An adhesive applied over the sealer after the sealer is partially cured adheres a retro-reflective material thereto. The retro-reflective material increases visibility of the railroad crossing.

Abstract: Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presence of a coagulant, aggregating to form particles, coalescing to form fused particles, and removing the fused particles from the aqueous dispersion. Wax dispersions can be added either after mixing or during aggregation, so that wax is excluded from the core of the toner particles.

Abstract: Methods for choosing groups for a static Diffie-Hellman key agreement protocol to inhibit active attacks by an adversary are provided. In mod p groups, an even h is chosen of value approximately (9/16)(log2n)2, values r and n are determined using sieving and primality testing on r and n, and a value t is found to compute p = tn + 1 wherein p is prime. In elliptic curve groups defined over a binary field, a random curve is chosen, the number of points on the curve is counted and this number is checked for value of 2n wherein n is prime and n-1 meets preferred criteria. In elliptic curve groups defined over a prime field of order q, a value n = hr + 1 is computed, wherein n is prime and n-1 meets preferred criteria, and a complex multiplication method is applied on n to produce a value q and an elliptic curve E defined over q and having an order n.
