  • Publication number: 20070115113
    Abstract: A vehicle speeding alert system is implemented on a GPS enabled wireless device in communication with a wireless network. The alert system periodically determines the speed of a vehicle by determining the speed of the wireless device carried therein, using GPS signals received by the wireless device. For example, speed can be calculated by dividing a certain distance that the wireless device travels by the time it takes to travel that distance. The vehicle's speed is then compared to the speed limit of the roadway on which the vehicle is traveling. The speed limit is determined by comparing the wireless device's location to map data relating to the geographic area around the location. The map data may be stored on the wireless device, or obtained from a map database accessible over the network. If the vehicle speed is above the speed limit, a notification or alert is issued.

  • Patent number: 7221682
    Abstract: A controller 26 for a packet radio network 20 includes a processor 27 that, in turn, includes a plurality of processor resources 30A–30D for processing a plurality of packet classes. Each packet class has a different delay sensitivity associated therewith. The processor 27 allocates to each packet class at least a portion of at least one processor resource 30A–30D, the allocation being based on the delay sensitivities associated with each packet class. Each processor resource 30A–30D may have a processing threshold, and the processor 27 may determine, based upon arriving packets, whether at least one processor resource will exceed its processing threshold, thus defining at least one overloaded processor resource 30A. The processor 27 may reallocate at least a portion of at least one processor resource to process packets for the at least one overloaded processor resource 30A thereby defining at least one reallocated processor resource 30D.

  • Patent number: 7220388
    Abstract: Apparatus and method for increasing the concentration of a chemical substance in a fluid comprise a micro-fluidic elongated channel formed in a substrate, with the channel being in fluid-flow communication with an ambient region along its elongated dimension. In general, the fluid includes first and second chemical substances having different vapor pressures. The apparatus includes an evaporation controller for increasing the evaporation rate of the fluid from the channel into the ambient region, thereby increasing the concentration of the higher vapor pressure (HVP) substance in the portion of the fluid remaining in the channel and increasing the concentration of the lower vapor pressure (LVP) substance in the portion of the fluid evaporated into the ambient region.

  • Patent number: 7222214
    Abstract: A programmable non-volatile memory device includes block switching logic that enables device-level translation rules to be changed. The device-level translation rules map the external addresses received by the flash memory device to the internal addresses of the programmable non-volatile memory device. Because the device-level translation rules are changeable, the physical location in the programmable non-volatile memory device to which an external address maps can be changed in a manner that is transparent to off-device operations. By allowing device-level translation rules to be changed, block management functions can be accomplished within the programmable non-volatile memory device itself.

  • Patent number: 7221649
    Abstract: A monitoring technique is provided for diagnosing delays in file transfers between a server and a client via a network, which monitoring technique operates to make measurements of ordinary network traffic on a link unique to a given client/server pair connection. In particular, the invention operates to apply a set of rules to partition the file transfer time into increments attributable to specific identified causes. To that end, the invention intercepts and sorts traffic traversing a predetermined monitor point into a set of flows, wherein each flow consists of all of the traffic between one client and one server. For each flow the packet headers and timestamps of all packets passing in each direction are read. The partitioning of the file transfer times is based on the resulting data.

  • Patent number: 7221756
    Abstract: A hash function is applied to a prefix of a VIL input. The output is added to a suffix of the input. A block cipher is applied to results of the addition. An encryption function is performed on the prefix. The final output is the output of the block cipher and the encryption function. In a second encryption technique, a hash function is applied to an input, and the output of the hash function has first and second portions. A block cipher is applied to the second portion. The output of the block cipher is added to the first portion, and a second function is applied to the result of this first addition. The output of the second function is added to the second portion. An inverse hash function is then applied to the output of the first and second additions, creating an encrypted output.

  • Publication number: 20070110190
    Abstract: A system for implementing the soft decision of a 3-chip differential binary phase shift keying (DBPSK) optical signal using digital components. Pair-wise comparisons of three differentially detected signals are performed and analyzed by digital logic which determines the most likely sequence of data. In a first variant, pairs of adjacent data bits are detected simultaneously, whereas in a second variant, data bits are detected individually. The digital logic can be implemented using conventional logic gates.

  • Patent number: 7219228
    Abstract: A SYN packet bandwidth Distributed Denial-of-Service (DDoS) attack is defended against by intercepting and identifying SYN packets in a “DDoS gateway” advantageously positioned at the edge of the network to be protected (e.g., one hop upstream from the protected link), and by queuing these intercepted SYN packets in a separate queue from other TCP packet queues. Edge per-flow queuing is employed to provide isolation among individual TCP connections sharing the link. A fair scheduling algorithm such as round robin scheduling is used to ensure that SYN packets (such as those generated as part of a SYN bandwidth attack) cannot overwhelm the egress link in the presence of other TCP packets.

  • Patent number: 7218630
    Abstract: A wireless communication system uses a circuit switched link between a wireless unit and a base station to establish a data session with a network device in a packet data network. After the data session is established, the data session can proceed using a packet switched link between the wireless unit and the base station. By using the circuit switched link to send data session setup packets, the system avoids the delay associated with requesting and being allocated wireless resources in sending the setup packets using the packet switched link. Decreasing the delay associated with setting up the data session improves the data rate and throughput between the wireless communications system and the packet data network. For example, in an exemplary CDMA system, a circuit switched link is established to carry primary traffic (such as voice) and secondary traffic.

  • Patent number: 7216589
    Abstract: An ordnance fuse apparatus is described that uses electrical and mechanical, and optical devices. The ordnance fuse apparatus includes a controller to control an optical switch and a laser to detonate an explosive charge of the ordnance. Other embodiments include an accelerometer and/or spin detector for detecting that the ordnance has been fired and an optical detector for detecting the proper operation of the laser and a position sensor for detecting correct positioning of the optical switch. Another embodiment includes a microlens to focus the laser optical signal onto the ignitor. In yet other embodiments, the explosive charge is detonated either by ignition of an ignitor or by a shock wave from the ignitor. The resulting ordnance fuse apparatus has significantly reduced size and improved performance and safety.
