Capacity enhancement for multi-code CDMA with integrated services through quality of service and admission control
With the addition of high-speed data traffic to traditional CDMA cellular networks, there is a need to efficiently utilize system capacity so that the quality of service of existing voice and low-speed data users is maintained while new high-speed data users are added to the network. Methods and systems are presented that control allocation of power to users, quality of service requirements, and / or user activity levels to enhance capacity utilization. These methods and systems are based on a method for estimating the capacity of a CDMA carrier with both voice and data users using an interference-based analysis of the reverse link. In particular, the methods enhance capacity utilization in a multi-code CDMA network architecture, in which several codes are allocated to a single high-speed data user for parallel transmission.

The MULTIBODY AIRCRANE performs relative positioning, predictive control, and ballast control to achieve very heavy-lifting tasks on land or sea. Such tasks allow station keeping and precise transfer of very heavy payloads between ships underway. This scalable multibody system features three subcomponents: AIRSHIP, SKYCRANE and LOADFRAME. This semi-autonomous system combines aerodynamic (kinetic) and aerostatic (buoyancy force) lift with efficient power and propulsion. During low-speed flight, the Airship and Skycrane are decoupled but linked via a reelable Tether Control Line. Beneath the Skycrane, centered on its hull, a patented NIST (National Institute of Standards and Technology) RoboCrane (featuring a computer controlled six degrees of freedom (DoF) cabling system,) is attached, to precisely suspend and control a Loadframe, with or without payload. During subsonic forward flight, these Airship and Skycrane are coupled as a single airframe (fuselage and delta wing.)

Distributed packet processing architecture for network access servers
InactiveUS6954463B1Increase the number ofRaise countData switching by path configurationNetwork access serverComputer hardware
An access server architecture, and methods for use of the architecture, are disclosed. The architecture and methods are designed to increase the scalability of and balance processor load for a network access server. In this architecture, packet forwarding and packet processing are distributed amongst the cards serving the low-speed access lines, such that each line card is responsible for performing forwarding and packet processing for packets associated with the low-speed ports that line card serves. As the number of line cards expands, forwarding resources are expanded in at least rough proportion. The NAS route switch controller, and the high-speed ports, are largely relieved of packet processing tasks because the egress port uses a distribution engine that performs a cursory examination on one or more header fields on packets received—comprehending only enough information to allow each packet to be distributed to the appropriate line card for full processing.

Electronically controlled prosthetic knee
InactiveUS6764520B2Improve efficiencyImprove practicalitySpringsNon-rotating vibration suppressionLow speedMagnetorheological fluid
The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee which utilizes a plurality of interspersed and alternating rotors and stators to shear magnetorheological fluid in gaps formed therebetween. Advantageously, by operating in the "shear mode" there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed-eliminating the need for a transmission-and also for a wide dynamic torque range. One embodiment of the invention allows the rotors and / or stators to close the gaps therebetween to create a frictional torque component, thereby forming a "hybrid" braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.

Random Access Design for High Doppler in Wireless Networks
UE-initiated accesses within a cellular network are optimized to account for Doppler shift. A user equipment (UE) receives information that designates a particular access slot as high-speed and designates another access slot as low-speed within a given cell. The UE determines its relative speed to a serving base station (NodeB) within the cell. The UE selects either a baseline structure or an alternate structure if the relative speed is less than a threshold value or only an alternate structure if the relative speed exceeds the threshold value. The UE transmits a signal to the NodeB using the selected structure, such that the baseline structure is transmitted only in the designated low-speed access slot and that the alternate structure is transmitted only in the designated high-speed request slot.

Method and system for asymmetric satellite communications for local area networks
InactiveUS6205473B1Efficient communicationIncrease speedError preventionTransmission systemsNon symmetricLow speed
A method and system for providing high-speed, satellite-based information delivery is described. Improved communication channel efficiency is accomplished by employing an asymmetric data flow. The high bandwidth channel capacity of digital satellite systems is used for the download of large volumes of data. While relatively low speed communication channels are used for upstream data requests. The use of separate channels for upstream data and downloaded data provides an increased efficiency of use for typical internet and other electronic information service subscribers. A typical user in such systems generally makes relatively short information requests. These requests are then followed by large amounts of information being transferred to the user's computer in response to the request. The volume of data being downloaded often causes a capacity overload of typically used land lines. This invention solves this problem, without becoming prohibitively expensive, by employing digital satellite dish receivers to receive the high volume of downloaded data and using the relatively low speed communication channels low volume upstream requests. Moreover, this invention is designed to interface with all common communication devices as well as being designed to operate on and with all common computing platforms.

InactiveUS7013162B2Increase speedFree channel bandwidthAssess restrictionNetwork topologiesHigh rateLow speed
A technique for communicating with a local area network (LAN) via a wireless connection determines whether a first short-range, high-speed, wireless communication path is available and connects to the LAN using a longer range, lower speed wireless communication path if the short-range, high-speed wireless communication path is not available. The low-range, high-speed wireless communication path is a wireless LAN connection such as an IEEE 802.11-compliant wireless LAN and the long-range, low-speed wireless communication mode is a cellular CDMA-type connection. Determining whether the first IEEE 802.11 mode is available can be done by detecting a beacon signal, or by transmitting a probe request message and detecting a probe response message in response to the probe request, indicating the presence or availability of the short-range, high-speed wireless communication path. Alternatively, the availability of short-range, high-speed wireless communication path can be detected by simply detecting activity on it.
