Publication number: 20120182180Abstract: Positioning systems and methods comprise a network of transmitters that broadcast positioning signals comprising ranging signals and positioning system information. A ranging signal comprises information used to measure a distance to a transmitter broadcasting the ranging signal. A reference sensor array comprising at least one reference sensor unit is positioned at a known location. A remote receiver includes an atmospheric sensor collecting atmospheric data at a position of the remote receiver. A positioning application is coupled to the remote receiver and generates a reference pressure estimate at the position of the remote receiver using the atmospheric and reference data from the reference sensor array.

Patent number: 6993542Abstract: Truly random numbers are generated with a minimum of extra hardware by taking advantage of the inherent noise in a communication channel. Random numbers can thus be generated without specialized manufacturing requirements and can be incorporated to conventional integrated circuits with minimal additional logic. The random number generation technique offloads the processor from performing extensive generation calculations without the use of the hardware accelerator. This random number generation technique may find application in, e.g., any network device that participates in a virtual private network or is used to implement electronic commerce.Type: GrantFiled: March 12, 2001Date of Patent: January 31, 2006Assignee: Cisco Technology, Inc.Inventor: Subramanian Meiyappan

Patent number: 6578098Abstract: The present invention is drawn to a computer implemented method and system for synchronously driving slave responses onto an ASB (advanced system bus) bus. On the one hand, in response to a read transfer from a ASB master, an ASB slave predicts the read transfer to be intended for a device attached to the ASB slave if the device is ready to return read data. On the other hand, in response to a write transfer from the ASB master, the ASB slave predicts the write transfer to be intended for the device attached to the ASB slave. In both scenarios, a device select signal (Dsel) is utilized to validate these two predictions. That is, the read slave response driven by the ASB slave does not enter the ASB bus when the device select signal does not select the ASB slave. Also, the write slave response driven by the ASB slave does not enter the ASB bus when the device select signal does not select the ASB slave.Type: GrantFiled: November 4, 1999Date of Patent: June 10, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Subramanian Meiyappan, James J.
