  • Patent number: 6279689
    Abstract: A hydraulic parking brake assembly for a railroad vehicle braking system is provided for an automatic application of the parking brake in the absence of an air source. The hydraulic parking brake assembly comprises a hydraulic actuator having a hydraulic piston and a spindle. The spindle is capable of entering a hole provided in the back surface of a pneumatic cylinder of the railroad vehicle braking system. Upon the application of hydraulic fluid within the hydraulic actuator, the hydraulic piston and spindle move in a forwardly direction, causing the spindle to contact the piston within the pneumatic cylinder and apply a force to this pneumatic piston as if pneumatic pressure were applied within the pneumatic cylinder. Such application of force to the pneumatic piston initiates a braking sequence to achieve application of the parking brake to the railroad vehicle eliminating the need to manually apply the parking brake with a hand wheel.

  • Patent number: 6278376
    Abstract: Method of facilitating release of an object caught by one or more closing transit vehicle door(s) in a motorized door system having a two stage lock, the two stage lock having a fully locked position and a pushback lock position. The method includes detecting the presence of the object by the effect of the object on either the position or the velocity of the door(s). The method also includes determining whether the door(s) are in a pushback range between the fully locked position and the pushback lock position. If an object is detected and the door(s) are in the pushback range, then one or more signals are supplied to a motor of the door(s) to move the door(s) in the door opening direction to or toward the pushback lock position.

  • Patent number: 6275165
    Abstract: A system reliably communicates brake commands from a master controller on a lead locomotive to the brake equipment on each rail vehicle of a freight train. The system includes a mechanism for detecting whether the brake commands are being successfully communicated over a communications channel that is normally used to convey such commands from the master controller to the brake equipment on each rail vehicle. The system also includes on each rail vehicle a mechanism for communicating the brake commands that is independent of the communications channel. The mechanism for communicating conveys the brake commands from the lead locomotive to the rail vehicles only when the mechanism for detecting determines that communication over the communications channel has failed. The system further includes on each rail vehicle a mechanism for receiving the brake commands from the lead locomotive via the mechanism for communicating.

  • Patent number: 6266706
    Abstract: In a method of IP routing lookup in a routing table, comprising entries of arbitrary length prefixes with associated next-hop information in a next-hop table, to determine where IP datagrams are to be forwarded, a representation of the routing table is stored, in the form of a complete prefix tree (7), defined by the prefixes of all routing table entries. Further, a representation of a bit vector (8), comprising data of a cut through the prefix tree (7) at a current depth (D), and an array of pointers, comprising indices to the next-hop table and to a next-level chunk, are stored. The bit-vector (8) is divided into bit-masks and a representation of the bit-masks is stored in a maptable. Then, an array of code words, each encoding a row index into the maptable and a pointer offset, and an array of base addresses are stored. Finally, the lookup is performed.

  • Patent number: 6261195
    Abstract: An elongated support member extends generally vertically upward from a playing surface. An elongated arm extends outward from two opposite sides of the support member in generally perpendicular relationship to the support member. The arm has freedom of rotation about the support member. At least two blocking dummy holders are configured to be suspended from the arm such that at least one each of the blocking dummy holders is positioned on each of the two opposite sides of the support member. Each of the blocking dummy holders has freedom of rotation about the arm, whereby a person on the playing surface who strikes a blocking dummy held by the blocking dummy holder will cause the arm to rotate about the support member and the blocking dummy to rotate about the arm.

  • Patent number: 6247566
    Abstract: A device for transmitting torque between two rotatable, coaxial shaft members (1, 2) contains a number of alternate clutch discs (5, 6) for counteracting differential rotational speed between the two shaft members. Planetary gear means (11, 15, 16-20) are connected to the first shaft means (1). A pressure plate (7) is connected to the second shaft member (2) and is axially displaceable against the clutch discs (5, 6) for their engagement. Transmission means in the form of rollers (10) are arranged between the gear means and the pressure plate for axially displacing the pressure plate against the clutch discs at a certain rotation differential between the gear means and the pressure plate. Electrical braking means (21-24) connected to the gear means can provide a force to the transmission means for its axial displacement.

  • Patent number: 6249722
    Abstract: An improved method is used to control the pressure in the brake pipe of a train. The train is equipped with an automatic brake handle, an equalizing reservoir, a brake pipe control device and a computer for controlling the control device according to position of the handle. The method involves the steps of: moving the handle to a point along its range of motion; and storing in the computer as a setpoint the value desired for the pressure in the brake pipe. At whichever point the handle occupies along its range of motion, there is a particular pressure setpoint corresponding thereto. The method next includes the steps of: directing the computer to command the control device to modify the actual pressure in the equalizing reservoir to the setpoint thereby also causing the actual brake pipe pressure to approach the setpoint.
