Abstract: The present invention is directed to a seed cartridge assembly including a cartridge body, a seed drawer slideably disposed within the cartridge body, a radiation shield slideably disposed around the cartridge body and a seed retainer in the seed drawer. Further embodiments of the present invention include a seed cartridge assembly as described above including a gravity lock between the seed drawer and the cartridge body. Further embodiments of the present invention include a seed cartridge assembly as described above, wherein the cartridge body includes a magnification lens positioned above the seed drawer. Further embodiments of the present invention include a seed cartridge assembly as described above wherein a seed channel extends axially along the seed drawer and a plurality of vents extending from the seed channel to an exterior surface of the seed drawer.

Abstract: An intra-train communication system includes a locomotive control unit (LCU) establishes a communications link between a lead unit and a remote unit which operate using different protocols and/or in different frequency bands. To accomplish this objective, the LCU automatically detects the type of lead unit and remote unit installed on the train. If the types are not the same, the LCU resolves any serial link protocol and arming differences that might exist in a manner virtually transparent to train operators. As a result, data is communicated between the lead and remote units in a way which requires less operator intervention and no software changes to the control computer of the head unit.

Abstract: Radio-based control of railroad train brakes is effected in which brake systems are computer controlled. An End of Train (EOT) system is used in which microprocessor circuits of a Locomotive Control Unit (LCU) and an EOT unit are programmed to perform these and other functions. The computer system has several states. On power on, the system enters the Setup state during which the system stores about one minutes worth of both brake pipe and equalizing reservoir pressure data. This data is later used to determine the rate of change of these pressures to determine stability. Once setup is complete, the system enters the Stability state during which operating pressures are determined. When the equalizing reservoir pressure, the brake pipe pressure and the brake pipe pressure at the end of the train are stable, the EOT unit is commanded to update operating pressures stored in its microprocessor control circuit. Once the several pressures have been found to be stable, the system goes to the Release state.

Abstract: This device relates to an athletic leg brace apparatus consisting of a flexible upper harness strap, a first- and second-lateral suspension rod having two terminal ends, each having holes or orifices spaced along the longitudinal axis thereof; a first- and second-lower lateral suspension rod having two terminal ends and holes or orifices spaced along the longitudinal axis thereof; a first- and second-shaped, contoured knee protection pad, suitable padded material layers internally disposed to first- and second-lower lateral suspension rods, whereby an upper and lower three-piece modular assemblies are formed. Means for securing said upper and lower assemblies to the upper and lower leg whereby the leg is braced and the knee protected.
