An exchange station has openings for drones, a passenger check-in/check-out bay for processing passengers, a drone connect/release bay, having apparatus adapted to manage passenger pods mounted on smart chassis, and a computerized control system in wireless communication with control circuitry in the drones and smart chassis, guiding smart chassis with mounted passenger pods and drones, to make the exchange of pods from the smart chassis to drones. A passenger entering the passenger check-in bay is loaded into a pod mounted on a smart chassis, the pod with passenger is transported to the drone-connect/release bay, and the pod is there joined to a bare drone and disconnected from the smart chassis, the drone leaving with the passenger pod to a destination, and the smart chassis traveling away from the drone connect-release bay.

Intelligent pod management and transport

A transport system has a first set of substantially parallel rails supported above ground level by support structures, a trolley having wheels mounted to a frame with the wheels engaging the rails, at least one wheel powered to move the trolley along the set of rails, a portion of the frame depending between the rails to a level below the rails, and a downward-facing latching interface on the depending portion of the frame, and a pod enabled to carry a passenger or parcels, or both, engaged by an upward-facing latching interface to the downward-facing latching interface of the trolley, such that, as the trolley travels along the rail set, the pod is carried along below the rail set.

Intelligent POD management and transport

A drone transport system has a carrier pod adapted for carrying a passenger or parcels with the passenger or parcels enclosed, the carrier pod having a first attachment interface at an uppermost extremity, the attachment interface having one or first physical attachment elements, and a flight-enabled drone having a downward-facing second attachment interface having one or more second physical attachment elements compatible with the first physical attachment elements of the carrier pod. The flight-enabled drone is controllable to approach the carrier pod from above, to align and engage the second physical attachment elements with the first physical attachment elements, to lift and carry the pod from one place to another, and to land and disengage the first and second physical attachment elements, leaving the carrier pod at a new place.

Drone transport system

A transport system has a wheeled, steerable, self-powered, self-navigating carrier vehicle, having a substantially planar support frame, an on-board, rechargeable, battery-based power system, control circuitry, including GPS circuitry, on-board the carrier vehicle, adapted to drive and steer the carrier vehicle, and an upward-facing carrier interface adapted to the support frame, the carrier interface having first physical engagement elements, and a passenger pod adapted to carry both packages and persons, the passenger pod having a structural framework, a rechargeable, battery-based power system, and a downward-facing pod interface adapted to the structural framework, the carrier interface having second physical engagement elements. The passenger pod, placed upon the carrier vehicle, engages the downward-facing pod interface to the upward-facing carrier interface by the first and second physical engagement elements.

A charging system for a drone carrying a passenger pod has a base structure connected to a power grid, a row of substantially planar wireless charging pads supported by the base structure, and a computerized controller enabled to communicate with a drone and to initiate, control and stop charging power. As a drone carrying a passenger pod approaches the charging-system, the computerized controller directs the moving drone into a path bringing a charging receiver pad of the passenger pod carried by the drone, and connected to a battery of the passenger pod, into proximity with the row of substantially planar charging pads, and directs the drone to move the carried passenger pod along the row of charging pods, managing speed and direction of the moving drome along the path, as charging of the battery of the passenger pod is accomplished.

Drone charging stations

A charging system for drones has a base structure connected to a power grid, a connector extendable from the base structure and ending in a charging interface compatible with a charging port of a drone, and a computerized controller at the base structure enabled to communicate with a drone and to initiate, control and stop charging power. As a drone approaches the charging-system, the controller directs the drone into position for charging, manages connection of the charging interface to the charging port of the drone, initiates charging power, monitors progress of charging, and upon completion of charging, disconnects the charging interface from the charging port of the drone.

The present invention provides for communication of data to and from isochronous data sources and sinks. Preferably, a portion of bandwidth on the link is also dedicated to convey data to and from non-isochronous sources and sinks, as well as to permit conveying housekeeping information (such as information relating to data sources and destinations) and status and control maintenance information. A management port is included in the isochronous switching devices to allow monitoring or diagnostic access to the serial isochronous data stream to and from all physical layer portion connections. Accessing one connection's data stream does not affect normal operation of the other connections.

Data communication network with management port for isochronous switch

An apparatus and method for transferring data between two entities in a time slot interchange fashion. The apparatus and method includes a buffer memory comprised of three sections to accommodate up to one cycle of skew between the two independently operating entities. Cycle start detection logic coupled to the two entities controls or, as implemented in the preferred embodiment, designates a physical location within the buffer memory for each of the three sections upon receipt of cycle start reference signals from the two entities.

Time slot exchanger mechanism in a network for data communication having

A data communication system such as a local area network or a wide area network capable of transmitting isochronous data. The system conveys both isochronous data and non-isochronous data by time multiplexing data into a recurring frame structure on a 4-bit nibble basis. The arriving data is de-multiplexed at a hub into separate channels which are forwarded to separate hardware appropriate for handling the particular data stream. The data is passed hierarchically from a source, through a node, and to a hub. The hub places the data into an internal connection memory for switching onto a high bandwidth bus for distribution to other destination hubs, nodes, or sinks, except, where the source node and destination node are attached to the same hub, the hub provides a local loopback to the destination node, thus avoiding the need to place the transmitted data onto the bus. This system conserves room on the bus for other isochronous and non-isochronous data.

Local loopback of isochronous data in a switching mechanism

A data communication system, such as a local area network, is provided with a capability of transmitting isochronous data. The system conveys both isochronous data and non-isochronous data by time-multiplexing the data into a recurring frame structure on a four-bit nibble basis. The arriving data is de-multiplexed at the hub into separate channels for handling the separate streams by appropriate hardware. When no calls are in progress, a low power mode enables two ends of a network link to reduce power consumption by transmitting a single pulse once every 125 microseconds in lieu of transmitting an entire cycle template. Synchronization while in low power mode allows circuitry at both ends of a network link to remain synchronized to a single reference clock.

Low power isochronous networking mode

A data transfer delay compensation system for a data communications system having a first transceiver and a second transceiver wherein the first transceiver includes circuitry for transferring an external cycle reference signal and a cycle delay signal to the second transceiver. The second transceiver includes circuitry for transmitting the received cycle reference back to the first transceiver a given time period after receipt of the cycle reference. The first transceiver receives the cycle reference transmitted from the second transceiver and measures a phase difference between the received cycle reference and the external cycle reference signal in order to update the cycle delay signal.
