Patent number: 8184535Abstract: Flow control techniques for co-localized wireless local area network (WLAN) and Bluetooth (BT) allowing efficient sharing of radio medium are disclosed. In one embodiment, a method includes deriving an available medium time (TAV) for the WLAN device to communicate with a peer WLAN device based on schedule data forwarded by the BT device, transmitting a first data from the WLAN device to the peer WLAN device if the BT device becomes inactive and if the TAV is greater than a threshold time, and transmitting a second data from the WLAN device to the peer WLAN device if the TAV is less than the threshold time. The first data indicates that the WLAN device is to come out of a power save (PS) mode and the second data indicates that the WLAN device is to enter the PS mode.Type: GrantFiled: July 23, 2008Date of Patent: May 22, 2012Assignee: Wipro LimitedInventor: Bruno Jechoux

Patent number: 8180048Abstract: The invention generally relates to computational transformation process, which has applications in cryptography, random number generation, hash code generation etc. The computational transformation module uses a keyset, which is designed using a two dimensional array. Since the process of forward transformation used in the invention is a symmetric encryption process and if used to send data securely over a communications network, the same keyset needs to be present at the sending computer to encrypt the data and the receiving computer to go through a reverse transformation and decrypt the data. When the first ‘n’ bit block of input-data is transformed into the first ‘m’ bit block of output-data, the keyset is transformed into a different keyset based on a nonlinear or one-way transformation on the keyset. The next input block is encrypted using a transformed keyset, hence satisfying Shanons theory of perfect secrecy.Type: GrantFiled: September 14, 2004Date of Patent: May 15, 2012Inventor: Prahlad P Singanamala

Patent number: 8050230Abstract: A method of triggering handoff of a mobile station to a candidate BSS, for VoWLAN communication, uses a roaming controller for monitoring link qualities of the serving and candidate BSS by selective/controlled fast scanning through RSSI screening at each packet reception. Using link qualities, a list of candidate BSSs for handoff is maintained. The controller selects a candidate BSS for handoff and completes pre-authentication of the mobile station with the selected best candidate BSS. When the link quality of the of the selected candidate BSS becomes better than that of the serving BSS, handoff is triggered. Link qualities may be monitored by screening a metric other than RSSI. When no candidate BSS is found, scanning is reduced/temporarily interrupted, to conserve power. When the serving BSS link quality is above a given threshold when the mobile station is in the serving BSS center, the functions of fast scanning and pre-authentication are interrupted.Type: GrantFiled: July 7, 2007Date of Patent: November 1, 2011Assignee: Wipro LimitedInventor: Bruno Jechoux

Patent number: 8020031Abstract: A system and method for customizing a SCSI error response received from a SCSI target in a storage network environment is disclosed. In a method for customizing a SCSI error response received from a SCSI target in a storage network environment, a SCSI command is received from a SCSI initiator by a SCSI to ATA bridge. The received SCSI command is translated to provide an ATA command. The ATA command is then sent to an ATA drive. The ATA command is executed by the ATA drive. During execution, if an error occurs, an ATA error response is sent by the ATA drive to the SCSI to ATA bridge. The received ATA error response is translated to a SCSI error response. The SCSI to ATA bridge then obtains a customized SCSI error response using an error look-up table. Further the customized SCSI error response is sent to the SCSI initiator.Type: GrantFiled: April 28, 2010Date of Patent: September 13, 2011Assignee: LSI CorporationInventors: Nilesh Govande, Rakesh Verma, Vishal Thakkar, Dan Meyer

Patent number: 7986651Abstract: An event-driven, power-saving method of controlling link adaptation for wireless transmission in battery powered stations through selectively controlled PHY parameters uses a PHY parameter controller for selectively changing the PHY parameters. The number of retransmissions required per time unit (herein ReTXrate), and missing ACK numbers (e.g., more than two) are used as first and second link quality metrics in the method, instead of the PER as in prior art. Also, the measured ReTXrate after each packet transmission is used for establishing lower and higher thresholds for the ReTXrate. Based on the lower and higher ReTXrate thresholds and based on said missing ACKs, link adaptation by way of changing the PHY parameters through the PHY parameter controller is triggered. The link adaptation method is especially suitable for VoIP traffic but applies to non VoIP traffic too (e.g., data,) including FTP and web browsing situations, and conserves battery power in mobile stations.Type: GrantFiled: July 2, 2007Date of Patent: July 26, 2011Assignee: Wipro LimitedInventor: Bruno Jechoux

Patent number: 7974185Abstract: A 3 fiber line switched ring (3FLSR) provides protection for (optical) transmission networking wherein N nodes are connected via 3 lines (or optical fibers) in a ring topology. Two of the three fibers form a main transmission line and may transmit in one direction in the ring whereas the third might transmit in the opposite direction. This architecture of the 3FLSR provides a dual protection scheme, including a bi-directional line switching coupled with a unidirectional line switching. Traffic is categorized based on the level of protection available for the particular traffic type. The first two transmitting fibers form a bi-directional ring, carrying primary and secondary traffic which can survive 2 and 1 failures on the ring respectively. The third fiber may form a unidirectional ring, carrying additional traffic that can be pre-empted in case of multiple failures in the bi-directional ring. The 3FLSR enables reconfiguration of existing 2/4 fiber rings and conforms to applicable standards.Type: GrantFiled: October 18, 2005Date of Patent: July 5, 2011Assignee: Wipro LimitedInventors: Anshuman Manral, Praveen Chathnath, RamNarayan Srinivasan, Sourav Das
