Abstract: Hybrid vehicle design circuitry quantifies values for utility/disutility variables of a hybrid vehicle design by evaluating a hybrid vehicle model over a collection of drive cycles/routes. The utility/disutility values include at least one of: total time or additional time beyond a reference time needed for the hybrid vehicle design to complete the drive cycles/routes, a fraction or number of the drive cycles/routes for which the hybrid vehicle design fails to achieve a target velocity, and amount of time or distance over which the hybrid vehicle design fails to achieve a target acceleration or the target velocity over the drive cycles/routes. The hybrid vehicle design circuitry calculates one or more specifications of a hybrid vehicle design based on the utility/disutility values.

Abstract: A hybrid vehicle includes at least one axle, an energy storage device disposed within the hybrid vehicle, a fuel consuming engine, a power boosting feature, and a controller. The fuel consuming engine is operably connected to selectively provide power to at least one of the energy storage device and the at least one axle. The engine is capable of providing at least the mean but less than a peak power to drive the hybrid vehicle over a typical route. The power boosting feature is configured to provide the fuel consuming engine with additional power to achieve a desired power to accelerate the hybrid vehicle. The controller is adapted to selectively control power flow to the one or more axles from one or more of the energy storage device, the engine, and the power boosting feature to achieve the desired power.

Abstract: A system includes multiple integrated circuits (ICs), each with a high supply level input and a low supply level input. With respect to the topology of these power connections, the ICs are connected serially between a high power supply level and a low power supply level, so that the low supply level input connection of each IC in the series is connected to supply the high supply level input of the next IC in the series. The high supply level input of the first IC in the series is connected to a chassis supply voltage line, and the low supply level input of the last IC in the series is connected to a chassis return voltage line. The system may include matching of parts at manufacturing time, and/or using active control circuitry so that the voltage across each of the chips is maintained within a range of operational values.

Abstract: One embodiment of the present invention provides a system for facilitating establishment of connections between a local endpoint and a remote endpoint. During operation, the system sends, from the local endpoint, a single connection-request message to a proxy server, which forks the single connection-request message to a number of remote endpoints. The system receives one or more response messages from the remote endpoints. A respective response message carries address information associated with the remote endpoint. Upon receiving the response message, the system sends an acknowledgment corresponding to the received response message to the corresponding remote endpoint via the proxy server, and establishes a connection between the local endpoint and at least one remote endpoint.

Abstract: A system and method in which user management and radio management functionalities associated with a wireless network, such as an IEEE 802.11 wireless network, are integrated to provide wireless network services thereof. In general, according to the present invention disclosed herein, a link layer authentication module for linking a plurality of wireless network layers to one another is integrated with a network management module, such that the network management module and the link layer authentication module together form an integrated user and radio management module which provides wireless network services for the wireless network. The use of link layer authentication under the IEEE 802.1x standard can be integrated with network management functionality thereof in order to associate both and provide a variety of useful wireless network services.

Abstract: A method for processing token identifiers for Layer 3 (L3) control channels when encapsulated in a tunneling protocol. Rather than encapsulating an L3 control channel with a secondary L3 (or Layer 4 ‘L4 ’) header, a generic (non-Layer 3 header) identifier, or token identifier, is used to encapsulate the control channel. For example, the token identifier may be a simple bit pattern that does not require a complex, confusing or redundant IP/UDP routing table lookup. Instead, the token identifier simply alerts the forwarding entity that local processing of the packet's data is required (e.g., that the packet contains control channel data).

Abstract: A system and method for restricting access to a wireless network is disclosed herein. One or more access points are generally associated with the wireless network (e.g., an IEEE 802.11 wireless network), and a visitor gateway for automatically preventing visiting user from directly entering the wireless network. A command and control center communicates with the access points and the visitor gateway and controls data transfer and routing thereof. The visitor gateway can communicate with a remote computer network (e.g., the Internet) and restricts access to the wireless network by a visiting user through or from the remote computer network. The command and control center also can automatically route the visiting user to the visitor gateway when the visiting user attempts to access an access point associated with the wireless network.

Abstract: A wireless access point includes an ability to transmit signals over a plurality of channels and receive signals over the plurality of channels and have means for synchronizing transmission on a first channel to a first station and transmission on a second channel to a second station, such that acknowledgements are not expected from one of the first and second stations while transmitting frames to one or more of the first and second stations, means for transmitting over at least two of the plurality of channels simultaneously, means for receiving over at least two of the plurality of channels simultaneously. The number of channels might differ from implementation to implementation, but allows for simultaneous communication over the multiple channels with synchronization such that transmission on a channel is done while not expecting acknowledgements on any of the other channels.

Abstract: A system and method for managing control functions associated with access points of a wireless network. In general, one or more access points are associated with the wireless network (e.g., IEEE 802.11 wireless network). A control module is generally associated with the wireless network, wherein the control module manages and controls the access points associated with the wireless network, such that one or more control frames received by the access point are automatically transferred to the control module, which thereafter transfers a response back to the access point, thereby granting or denying access to the wireless network to users thereof based on the response transferred from the control module.

Abstract: A system and method for generating multiple independent networks using one or more access points of a wireless network are disclosed herein. An access point can serve multiple independent networks by partitioning broadcast messages such that less than all of the network devices able to receive data from the access point do receive and further process that data. In one embodiment, the partitioning is done by having different sets of one or more shared keys for different independent networks and encrypting frames. In that approach, broadcast frames for one network are received by network devices in the other networks, but are not decoded properly as the devices in the other network do not have access to the shared key needed to decode the broadcast frames. As a result, network devices in one network will discard broadcast frames of other networks.

Abstract: A system and method for monitoring radio spectrum traffic and interference thereof in a wireless networks. One or more access points are generally associated with the wireless network and monitor passing frames addressed to the access point or otherwise. A command and control center is associated with the wireless network and is capable of communicating with the access points to receive data associated with one or more frames monitored by such access points. Additionally, the command and control center may direct an access point to actively generate radio traffic to be monitored. The returned data can be used to generate a radio mapping of the wireless network and the radio environment thereof based on data received from the access points.
