  • Patent number: 10017197
    Abstract: A first crossing predictor uses signals from a pair to spaced apart receivers, which may be located on opposite sides of a transmitter, to determine on which side of a crossing an approaching train is located. If the first predictor upstream with respect to the approaching train, the first predictor transmits signals to instruct a downstream adjacent predictor to activate its warning device at a constant warning time (referred to as DAXing).

  • Patent number: 10005477
    Abstract: A vehicle which is intended to travel along a downward sloping cable, which is suspended between two supports having a change in elevation. Preferably, the vehicle includes a fuselage, a trolley assembly, a translation system, a seat, a counterweight system, and at least one wing. The trolley assembly is attached to the cable. This connection allows the vehicle to travel along the cable. A counterweight system is included in order to balance the weight of the rider sitting in the seat below the fuselage. This allows the vehicle to easily rotate, via rotary joint, around the cable while traveling along the line. Preferably, the rider can induce roll by either activating ailerons or by rotating one of the wings about the lateral axis in order to increase the lift on one side of the aircraft depending on whether the wings are fixed.

  • Patent number: 10000892
    Abstract: A method of interchange for an evacuated tube transport system includes tubes for enabling capsule movement within the tubes. The tubes are evacuated and the capsules magnetically levitated within the tubes. The tubes have an interchanges having diverging and converging tubes, respectively. A control system includes divergence force elements having permanent magnets that are selectively orientable polarity to enable capsule control, or electro magnets with polarity selectively switchable to enable capsule path control. The method selectively energizes the force elements to enable the capsule to diverge or converge in an interchange. An interrupter also regulates the force elements. The method activates the force elements and disables deactivation of the force elements before the capsule diverges in the interchange. The method balances divergence forces through center of gravity and through center of lift on receiving a request for divergence.

  • Patent number: 9995006
    Abstract: A new type of railway sleeper is composed of fiber-stabilized stoneware. By using a plurality of fiber-layered stone plates bonded to one another in such a way that prestress is generated in the stoneware, a permanently high-performance-capable sleeper is obtained, which is made of natural materials such as granite or basalt which occur almost everywhere on the earth in unlimited quantities and have a substantially longer service life and are substantially more resistant to influences of the weather and the environment than previous solutions. In addition, the sleeper or the intermediate spaces thereof are equipped with photovoltaic modules which together form a power unit when they are coupled together and connected electrically to the rails. Such sleepers can also be partially hollow as a light weight design variant. Lightweight variants with a hollow profile can be filled entirely or partially with track ballast from the side during the laying process.

  • Patent number: 9994242
    Abstract: The present disclosure teaches inter-vehicle communications for avoiding rear collision of rail vehicles on a railroad. For example, a collision avoidance system may comprise an end-of-train device and a V-aware unit located on different vehicles. The two devices may be configured to wirelessly communicate with each other, and then detect each other's presence by estimating a distance between them. Warnings may be issued to respective operators against a collision hazard when the distance drops to or below a pre-determined threshold.
