Patent number: 10697653Abstract: An air-conditioning system is provided, comprising: an air conditioner including a first fan having a first fan input configured to receive first input air, and a first fan output configured to generate a first output air stream in a horizontal direction, and a second fan having a second fan input configured to receive second input air, and a second fan output configured to generate a second output air stream in the horizontal direction; an air baffle including a first upflow duct attached to the air-conditioner and configured to direct the first output air stream into a first deflected air stream flowing in a first direction between 0 degrees and 45 degrees from vertical, and a second upflow duct attached to the air-conditioner and configured to direct the second output air stream into a second deflected air stream flowing in a second direction between 0 degrees and 45 degrees from vertical.Type: GrantFiled: June 29, 2018Date of Patent: June 30, 2020Assignee: Mitsubishi Electric US, Inc.Inventors: Joseph Paul Bush, Khurram Ali, Peter Christian Flynn

Patent number: 9481487Abstract: The present application provides a multi-piece box. The multi-piece box may include a body blank with a number of body panels and a number of second blanks with a second blank panel. The second blanks may be attached to the body blank. One or more of the body panels may include a first dimension along a first direction, the second blanks may include a second dimension along the first direction, and the second dimension may be greater than the first dimension such that the second blank panels may create a protruding end with respect to the one or more body panels.Type: GrantFiled: January 8, 2014Date of Patent: November 1, 2016Assignee: GEORGIA-PACIFIC CORRUGATED LLCInventors: Christopher Evan Dean, Yavuz Aksan, Wayne P. Gasior, Ernest B. Widner, Khurram Ali

Patent number: 7443829Abstract: The present invention provides a method of improving the performance of a CDMA based wireless network, such as a 3G cellular network for example. Interference cancellation is effectively performed earlier by using the channel request such as a reservation packet from a mobile terminal to estimate interference from that mobile on existing mobile users and interference on the mobile from existing mobile users, by determining the relative transmission timing of the new mobiles channel request compared with the transmission timings of the existing mobiles. The base station determine the cross-correlation between the codes already assigned to the existing users and the code to be allocated to the new user in order to determine an interference measure. This interference can then be cancelled from the new mobile when its data packets are received.Type: GrantFiled: June 23, 2005Date of Patent: October 28, 2008Assignee: Toshiba CorporationInventors: Khurram Ali Rizvi, Yuk C Chow, Tomoya Horiguchi

Patent number: 7386032Abstract: Spread spectrum receiver architectures and methods are described for reducing interference, particularly the interference observed at a user-end terminal in a W-CDMA 3G mobile communications system. Interpath interference which arises due to non-zero cross and auto correlation of more than one spreading code is suppressed by estimating a transmitted signal stream, or a plurality of such signal streams in the case of a plurality of multipath components, respreading this estimated signal and subtracting non-orthogonal interference contributions from a received signal. The techniques provide an improved bit error rate or equivalently, enhanced capacity for a digital mobile communications network.Type: GrantFiled: January 24, 2003Date of Patent: June 10, 2008Assignee: Kabushiki Kaisha ToshibaInventors: Michael Philip Fitton, Anthony Craig Dolwin, Khurram Ali Rizvi, Yuk Ching Chow, Mohamed Rafiq Ismail
