  • Patent number: 9691292
    Abstract: A method for providing interactive training, whereby a video display and a base station are coupled in communication with a computer. A plurality of wireless handheld remotes are configured for wirelessly communicating with the base station, and each of the remotes is operable by a respective trainee of a group of trainees. Each remote has a remote ID unique from all other remotes and is stored in non-volatile memory of the computer; and the base station includes a base station ID code unique from all other base stations, and the base station ID is stored in non-volatile memory of each remote. Unique IDs prevents interference from other wireless devices including remotes paired with other base stations. It also makes it unnecessary for one training system to operate on a different channel from another training system.

  • Patent number: 8498567
    Abstract: A training system that provides web-based distribution, centralized control of pedagogy consistency and content customization, and efficient and economical resource utilization via group oriented training in which a plurality of trainees can be trained without the overhead of providing each trainee with an individual PC. Because the proven education delivery method includes entertaining situational modeling videos, game playing, and a high degree of interactivity, it assures high trainee comprehension with a minimum investment in hardware and instructor overhead.

Each remote remains in an inactive state and is operable to be activated via a respective activate signal transmitted from the base station, and the base station is operable to transmit an activate signal to one or more of the remotes, the activate signal being effective for enabling the remote to transmit a signal, wherein the remote is deactivated upon completion of transmission of signal.

  • Patent number: 6038980
    Abstract: Cabs, such as passenger and freight cabs, are transferred from one horizontal transport bogie that is moving along a track to another horizontal transport bogie moving at the same speed on an adjacent track. The cab may be transferred from one train or shuttle of moving bogies to another train of moving bogies, or may be transferred from a train of moving bogies to an auxiliary shuttle or bogie on a siding so as to permit the cab to be brought to a stop, either to allow transfer of passengers, to be moved into the car frame of an adjacent elevator for vertical transport within the building, or to simply await the coming of another train, traveling in either the same or in opposite direction, to which the cab may then be transferred.
