  • Patent number: 11184735
    Abstract: An information processing system includes a vehicle, a terminal device, and a server that can communicate with the vehicle and the terminal device. The vehicle repeatedly transmits positional information on the vehicle to the server at predetermined timings. The terminal device repeatedly transmits user identification information for identifying a user of the terminal device and positional information on the terminal device to the server at predetermined timings. The server determines, based on the positional information on the vehicle and the positional information on the terminal device, whether or not the terminal device is located in a reference region within a predetermined distance from the vehicle, and determines, based on the user identification information, that the user of the terminal device is on board the vehicle, when it is determined that the terminal device is located in the reference region.

  • Patent number: 8863669
    Abstract: Control of Linear Synchronous Motors involves a number of low level issues of motor control—such as sensing precise position, controlling current in stator windings, and obeying commands from high level controllers—and high level vehicle control—such as stopping and starting, switching and merging, limiting speed and acceleration, synchronizing relative motion, preventing collisions and accidents, and dealing with failures. In most cases there is a master controller that directs vehicles based on simple commands but in other cases it is desirable to allow an external agent to provide more detailed control—such as synchronizing motion between a vehicle and a robot or allowing human operator control. This patent describes a versatile control scheme that allows both simplified high level control and, when or where necessary, control by an external agent. The result is a transport system and method that provides efficient and precise movement of vehicles on a guideway.

  • Patent number: 7895951
    Abstract: Persons on a bicycle or other muscle-powered vehicle, equipped through an attachment means, with a reaction plate secondary of a linear induction motor, LIM, receive intermittent, augmenting propulsion forces from a sequence of spaced LIM primary coil assemblies, positioned flush with a surface on a pathway, to augment the rider's muscle-created propelling forces when the LIM primaries are receiving power supplied by a utility. At each LIM primary, interacting magnetic fields are commonly created as the attached bicycle LIM secondary is moveably positioned by the rider proximately the centerline of a respective LIM primary. The augmenting propelling force results as thrust, derived from the interaction of the respective magnetic fields of the primary and secondary of the now temporarily completed linear induction motor at the respective, spaced locations of the primaries along the pathway.

  • Patent number: 7173387
    Abstract: The invention relates to an arrangement for operating a magnetically levitated vehicle by means of an arrangement having at least one long-stator linear motor. The linear motors are sub-divided, longitudinally of a track, into individual motor regions (A) in each of which only one vehicle (7) is able to travel at a time. To make possible different frequencies of service for the vehicles (7), i.e. different intervals between the vehicles (7), the region boundaries (B) between at least two motor regions (A1, A2) which follow one another in the direction of travel are arranged to be variable.

  • Patent number: 6889616
    Abstract: A track support for the track of a magnetic levitation railway consists of a steel support having a closed hollow trapezoidal or hollow triangular cross section with closed end faces, whose cover plate projects, in the manner of a jib, with its longitudinal edge sections over the side wall web plates, and at the end of which cover plate a side guidance rail is arranged in each case. In order to keep the surfaces of the track support that are exposed to environmental influences as small as possible, a stator support web plate is arranged on the underside of each jib, between the ground-side end section of which plate and the adjacent side wall web plate and the adjacent side guidance rail horizontal plates are arranged, forming closed cavities, where two parallel web flanges between which the grooved cross members are screwed are provided per jib on the underside of the plates.

  • Patent number: 6651566
    Abstract: A transportation system includes a guideway lane and a power cable assembly extending along the guideway lane. The system further includes a vehicle configured to travel on the guideway lane. The vehicle includes a self-centering transformer that is movable along the cable assembly and configured to cooperate with the cable assembly to transfer power to the vehicle. In addition, the transformer includes a magnet array that creates a magnetic field for centering the transformer-with respect to the cable assembly as the transformer moves along the cable assembly.

  • Patent number: 6578495
    Abstract: A module for a linear motor propulsion guideway contains a combination of linear motor propulsion, vehicle guidance, position sensing, communication, and vehicle or pallet running surface subcomponents. These are integrated during the manufacturing into a single component or module for ease of shipping and precision of installation at a site where the guideway is to be installed. A single manufacturing operation is used to position, affix, and encapsulate the selected subcomponent(s) in a module or modules. For example, the component(s) can be designed to be located in a plastic injection mold, typically, a reaction injection mold (RIM), which allows the subcomponent(s) to be positioned, aligned, and encapsulated in a single manufacturing step that has only a several minute cycle time. In this manner positional accuracy among the relationship of the subcomponent(s) can be maintained within a small tolerance (on the order of 0.25 mm) while costs remain very low.

  • Publication number: 20030094115
    Abstract: A personal rapid transit (PRT) system having a linear induction motor installed on the bottom of a vehicle is provided. Since a linear induction motor is installed on the bottom of a vehicle, the structure of the personal rapid transit (PRT) system is simplified and the stable driving thereof is possible. Further, since an auxiliary ramification wheel is provided, an accident by the vehicle seceding from a track occurring during ramification can be prevented in advance. That is, since only a single linear induction motor is installed horizontally on the bottom of the vehicle and thus the vehicle is driven, the structure of the personal rapid transit (PRT) system is more simplified and becomes lighter, and a production cost can be reduced, in comparison with an existing system using a pair of linear induction motors. In addition, even if a ramification device is failed during ramification, a track secession can be suppressed with an auxiliary ramification wheel provided, to thereby guide a stable running.
