Abstract:
A system for minimizing damage on collision to a vehicle having at least one self-propelled wheel is disclosed. The system comprises a motor in a wheel of said vehicle which drives the vehicle, means for measuring the speed of said wheel, means for measuring the torque of said motor, means for monitoring the ratio of the torque of the motor to the speed of the wheel, and means for stopping said motor when torque:speed ratio exceeds an acceptable value.
Abstract:
A very fast, memory efficient, highly expandable, highly efficient CCNUMA processing system based on a hardware architecture that minimizes system bus contention, maximizes processing forward progress by maintaining strong ordering and avoiding retries, and implements a full-map directory structure cache coherency protocol. A Cache Coherent Non-Uniform Memory Access (CCNUMA) architecture is implemented in a system comprising a plurality of integrated modules each consisting of a motherboard and two daughterboards. The daughterboards, which plug into the motherboard, each contain two Job Processors (JPs), cache memory, and input/output (I/O) capabilities. Located directly on the motherboard are additional integrated I/O capabilities in the form of two Small Computer System Interfaces (SCSI) and one Local Area Network (LAN) interface. The motherboard includes main memory, a memory controller (MC) and directory DRAMs for cache coherency. The motherboard also includes GTL backpanel interface logic, system clock generation and distribution logic, and local resources including a micro-controller for system initialization. A crossbar switch connects the various logic blocks together. A fully loaded motherboard contains 2 JP daughterboards, two PCI expansion boards, and up to 512 MB of main memory. Each daughterboard contains two 50 MHz Motorola 88110 JP complexes, having an associated 88410 cache controller and 1 MB Level 2 Cache. A single 16 MB third level write-through cache is also provided and is controlled by a third level cache controller.
Abstract:
A method for improving airport and ramp throughput is provided. The method minimizes the time interval between an aircraft's landing and takeoff by independently moving the aircraft with an onboard electric driver that drives at least one of the aircraft's wheels on the ground without the aircraft's engines. Turnaround time and aircraft idle time are reduced by eliminating engine operation while the aircraft is moving in the ramp area. The time between when an aircraft is not moving between pushback and taxi forward is substantially eliminated, leading to more efficient ramp operations as ramp space is freed for through traffic.
Abstract:
A system, method, and computer readable medium for offering uptime adjustments to a work schedule for at least one currently unscheduled agent possessing at least one skill type, that comprises, accepting at least one forecasted manpower requirement of zero or more agents for an interval of time for a skill, requesting an uptime display for an unscheduled time period of the at least one currently unscheduled agent, assessing the type and number of skill types of the at least one currently unscheduled agent, determining a manpower availability for the an interval of time based upon all agents currently scheduled for each skill type based upon the forecasted manpower requirement, calculating a manpower delta between the forecasted manpower requirement for the an interval of time and the determined manpower availability for each skill type, and offering an uptime adjustment if the calculated manpower delta shows additional manpower is required for any skill possessed by the at least one currently unscheduled agent.

Abstract:
A method for reducing the amount of fuel required to be carried in flight by an aircraft is provided that substantially reduces the taxi margin amount of fuel required by an aircraft, thereby reducing the aircraft's weight and producing significant increases in fuel use efficiency and savings in fuel costs. The substantially reduced taxi margin amount of fuel is produced by equipping an aircraft with at least one drive wheel powered by at least one onboard drive means that cooperatively drive the aircraft on the ground during taxi between takeoff and landing without reliance on the operation of the aircraft main engines.
