Geographic-based communication service system with more precise determination of a user's known geographic location

A geographic based communications service system that includes a network and a plurality of access points connected to the network and arranged at known locations in a geographic region. One or more service providers or information providers may be connected to the network to provide services or information on the network. Content provided by the service providers may be based on the known geographic location of the user of a portable computing device (PCD). The known geographic location may be determined with a high degree of precision, using one or more access points and one of several different techniques. In one embodiment, the geographic location of the PCD may be determined within a radius of ten feet. Access points may be configured to determine the bearing of a signal received from a PCD, as well as the strength of the signal transmitted by the PCD. Access points may also be configured to send and receive signals with time stamps. These time stamps may be used to calculate signal travel time, thereby allowing a determination of the distance between an access point and a PCD. Each access point may include location circuitry. The location circuitry may include both analog and digital circuitry configured to perform the various methods used to determine the precise geographic location.

Traffic management system for a passageway environment

The present invention provides a system for coordinating multiple vehicles in a passageway environment (e.g., in underground mines). The system includes methods and apparatus for determining the global position and orientation of a vehicle in said passageway environment, and methods for planning routes and monitoring the travels of multiple vehicles in said passageway environment. A global position and orientation estimation system employs one or more odometric sensors and one or more range sensing devices. It works in three basic steps. In the first step, it records and processes sensor data that is descriptive of the passageway environment by moving the system through said passageway environment. In the second step, it generates a globally consistent map of said passageway environment. Finally, real-time localization is provided by employing odometric sensors and range sensing devices to determine the system's global position and orientation with respect to said globally consistent map, both initially and as it travels through the passageway environment. A route planning method accepts higher-level goals for a set of multiple vehicles in said passageway environment and generates a route plan for each vehicle that minimizes the travel time for the group of vehicles, while at the same time avoiding collisions between vehicles. Route plans are sent to the vehicles for implementation and a monitoring method tracks the global positions and orientations of the vehicles and ensures that both safety and efficiency are maintained.

Multi-path mitigation in rangefinding and tracking objects using reduced attenuation RF technology

A method and system for identification, tracking and locating in wireless communications and wireless networks. The method and system use reference and / or pilot signals that are present in wireless communications and wireless networks. The method and system might also use RTT, TOA and time-stamping measurements / techniques to determine one or more reference signals traveling time between the Base Station (eNB) or its functional equivalent and mobile device (UE) and or network device. Other wireless networks that do not use reference and / or pilot signals may employ one or more of the following types of alternate embodiments of present invention: 1) where a portion of frame is dedicated to the ranging signal / ranging signal elements; 2) where the ranging signal elements are embedded into (spread across) transmit / receive signals frame(s); and 3) where the ranging signal elements are embedded with the data. The method and system includes multi-path mitigations processor and multi-path mitigations techniques and algorithms which improve the track-locate accuracy. The method and system allow achieving increased accuracy by using multi-path mitigations processor and multi-path mitigations techniques and algorithms. The techniques of Digital Signal Processing and Software-Defined Radio are used.

Dynamic bidirectional green wave band intelligent coordination control method for urban traffic trunk line

The invention discloses an intelligent coordination control method of a dynamic bi-directional green wave band for an urban traffic trunk road. The method comprises the steps of starting, processing coordination parameters, processing intersection parameters, processing time and processing cycle, etc. The method adopts a double-stage control structure, namely, a control layer of a traffic control center server and a control layer of an intersection intelligent signal controlling machine, through the information interaction and the coordination of the traffic control center server and the intersection intelligent signal controlling machine, phase sequence is optimized in an on-line manner; and common period, highway section upper phase difference, highway section down phase difference, the starting time of an upper coordination phase, the starting time of a down coordination phase, green ratio at each intersection and other key control parameters are optimized and calculated on a real-time basis. The intelligent coordination control method gets rid of the limit of equal intersection intervals required for the coordination control of the green wave band for the urban traffic trunk road, and realizes the unceasing travel of bi-directional traffic flows on the main road by applying the traffic engineering technique, the artificial intelligence technique and the automatic control technique, thereby reducing the parking rate while the traffic capacity of the trunk road is improved, and obviously reducing the traveling time.

Systems and methods of inventory management utilizing unattended facilities

An inventory management system utilizes unattended facilities remote from a central warehouse for service parts logistics. Items are placed in inventory in secure enclosures at the unattended facilities by the inventory management service. The unattended facilities may be located near one or more customers to reduce a service technician's travel time and customers' inventory costs. A service technician utilizes a passcode to retrieve needed items. The service technician may order items that are not kept in the inventory of the unattended facility in which case the items may be delivered to the unattended facility and the service technician may receive a notification related to all the items that comprise an order that the order is ready for pick up at an unattended facility. Unused, used or damaged parts may be returned by a technician to a remote secure enclosure where such returned parts may be retrieved and disposed of, repaired or placed back into inventory if not damaged or after repair, and the processing of such returned parts begins by information entered into a data entry device at the remote secure enclosure location. Return items that are not damaged may be included in the inventory of an unattended facility.

Systems and methods of inventory management utilizing unattended facilities

An inventory management system utilizes unattended facilities remote from a central warehouse for service parts logistics. Items are placed in inventory in secure enclosures at the unattended facilities by the inventory management service or are delivered directly to the unattended facility.

A service technician utilizes a passcode to retrieve needed items. The service technician may order items that are not kept in the inventory of the unattended facility in which case the items may be delivered to the unattended facility and the service technician may receive a notification related to all the items that comprise an order that the order is ready for pick up at an unattended facility.
