  • Publication number: 20070253346
    Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for detecting potential forwarding loops in bridged networks. A switch monitors the movement of packet addresses in the forwarding table to different ports. If the port associated with an address changes multiple times in a short time duration, then a potential forwarding loop is detected, and a loop corrector is notified to take appropriate action to correct the problem, such as, but not limited to changing the state of a port to a blocking state or disabling an interface, etc. If there are multiple movements outside the short time duration, they may be correct movements adjusting to the actual reconfiguration of a network, and thus, these movements are effectively filtered out of consideration.

  • Publication number: 20070111812
    Abstract: The present invention is a putting tool to assist a golfer. The putting tool comprises a box like structural housing having a cavity therein. The housing is further defined by a top wall, bottom wall, back wall, first side wall, and an opposing second side wall. The front of the housing defines an opened an entry way for inserting foam into the cavity of the housing. An elastic band covers the front opening of the housing. At a predetermined location on the elastic band, a target is incorporated onto the band. Thus, when the golf ball hits the elastic band, the ball bounces off the band and automatically returns back to the putter.

  • Publication number: 20060256763
    Abstract: A fast roaming (handoff) service is provided for a WLAN infrastructure. A given mobile station (STA) obtains a pairwise master key (PMK) when it associates with an access point (AP) in the infrastructure. A neighbor graph identifies prospective APs to which the STA may then roam. At initialization, preferably the neighbor graph is fully-connected (i.e., each AP is assumed to be connected to every other AP). The PMK (obtained by the STA initially) is shared proactively with the neighbor APs as indicated in the neighbor graph. Thus, when the STA roams to a neighbor AP, because the PMK is already available, there is no requirement that the STA initiate a real-time request to an authentication server to re-associate to the new AP.

  • Publication number: 20060094369
    Abstract: An automatic channel selection (ACS) process enables an access point to determine a best channel available, i.e., the channel with a least amount of interference, for it operation. When ACS is enabled, the access point scans frequencies for all neighboring access points and their signal strengths. Based on this data, the access point then determines which frequency is least likely to be interfered with by these other access points. The access point switches itself to this frequency and begins operation. During normal operation, the access point may periodically rescan the air space and reevaluate its current operating channel. Preferably, every neighboring access point has its own channel, and the co-channel interference levels should be low enough so that there is a maximum coverage and high throughput for the network. If these characteristics cannot be achieved, the access point may then adjust its power automatically to reduce the interference level in the network.

  • Publication number: 20060056724
    Abstract: A non-iterative 3D processing method and system is disclosed for generic noise reduction. The 3D noise reducer is based on a simple conversion of the five types of noise to equivalent additive noise of varying statistics. The proposed technique comprises also an efficient temporal filtering technique which combines Minimization of Output Noise Variance (MNV) and Embedded Motion Estimation (EME). The proposed temporal filtering technique may be furthermore combined with classical motion estimation and motion compensation for more efficient noise reducer. The proposed technique comprises also a spatial noise reducer which combines Minimum Mean Squared Error (MMSE) with robust and effective shape adaptive windowing (SAW) is utilized for smoothing random noise in the whole image, particularly for edge regions. Another modification to MMSE is also introduced for handling banding effect for eventual excessive filtering in slowly varying regions.

  • Publication number: 20060050783
    Abstract: An efficient and non-iterative 3D post processing method and system is proposed for mosquito noise reduction, block localization and correction in DCT block-based decoded images. The 3D post processing is based on a simple classification that segments a picture in multiple regions such as Edge, Near Edge, Flat, Near Flat and Texture regions. The proposed technique comprises also an efficient and shape adaptive local power estimation for equivalent additive noise and provides simple noise power weighting for each above cited region. Temporal filtering configurations using Minimum Noise Variance Criterion are proposed for reducing temporally varying coding artifacts. A Minimum Mean Square Error or Minimum Mean Square Error-like noise reduction with robust and effective shape adaptive windowing is utilized for smoothing mosquito and/or random noise for the whole image, particularly for Edge regions.

  • Publication number: 20050224296
    Abstract: An improved system of variable speed drives that enhances the energy efficiency of an elevator system by enabling power transfer between the variable speed drives of two or more elevators via a common DC bus. Any combination of regenerative and non-regenerative variable speed drives may be used with the present invention. Energy storage devices may be connected to the common DC bus further improve efficiency.
