Patent number: 8442096Abstract: A system for detecting and identifying the identity of a base station or cell which transmits a scrambling code is provided. According to one aspect of the system, the system is used to perform scrambling code detection of eight (8) primary cells (each scrambling code's X-component being spaced sixteen (16) chips apart) in a group. According to another aspect of the system, a single scrambling code generator is used to generate a master scrambling code. The master scrambling code is then used to create individual scrambling codes which are used in correlation with received signals to detect in parallel which one of the eight (8) possible primary cells in the group transmitted the received signals. According to yet another aspect of the system, each of the correlators maintains a corresponding X-component segment of the master scrambling code.Type: GrantFiled: July 8, 2009Date of Patent: May 14, 2013Assignee: QST Holdings LLCInventors: Sharad Sambhwani, Ghobad Heidari

Patent number: 8296764Abstract: The disclosure describes internal synchronization in adaptive integrated circuitry which utilizes a data flow model for data processing. Task initiation and execution are controlled based upon data consumption measured in data buffer units, with initiation of and transitions between tasks based on a determined boundary condition within the data stream. When a data processing task is selected for synchronization, a boundary condition in a data stream is determined for commencement of the selected data processing task. Then, a timing marker for the commencement of the selected data processing task is determined relative to the data stream. The timing marker is dual-valued, providing a designated buffer unit and a designated byte or bit location within the designated buffer. The timing marker is communicated to the selected data processing task, which then commences data processing at a location in the data stream designated by the timing marker.Type: GrantFiled: September 9, 2004Date of Patent: October 23, 2012Assignee: NVIDIA CorporationInventors: Ghobad Heidari-Bateni, Sharad D.

Patent number: 8135427Abstract: According to an embodiment of the invention, a system and method to provide alignment of hibernation and active cycles is provided. When one device receives a beacon from one of its neighbors it can be implemented to check for the neighboring device's global cycle start countdown value and to compare it's global cycle start countdown value with its own. If the beacon from the neighboring device contains a global cycle start countdown value that is different from the device's own global cycle start countdown, the device can be implemented to check a predefined condition. For example, if a device's global cycle start time falls into the first half of a neighbor's global cycle, then the device changes its own global cycle start time to the global cycle start time of that neighbor. In another embodiment, if a device's global cycle start time falls into the first 256/K superframes of a neighbor's global cycle, then the device changes its own global cycle start time to the global cycle start time of that neighbor.Type: GrantFiled: February 6, 2007Date of Patent: March 13, 2012Assignee: Olympus CorporationInventors: Alaa Muqattash, Ghobad Heidari-Bateni

Patent number: 7986270Abstract: A system and method for estimating the range between two devices performs two or more ranging estimates with subsequent estimates performed using a clock that is offset in phase with respect to a prior estimate. The subsequent estimate allows estimate uncertainties due to a finite clock resolution to be reduced and can yield a range estimate with a higher degree of confidence. In one embodiment, these additional ranging estimates are performed at n/N (for n=1, . . . N?1, with N>1 and a positive integer) clock-period offset introduced in the device. The clock-period offset can be implemented using a number of approaches, and the effect of clock drift in the devices due to relative clock-frequency offset can also be determined. To eliminate the bias due to clock-frequency offset, a system and method to estimate the clock-frequency offset is also presented.Type: GrantFiled: January 2, 2008Date of Patent: July 26, 2011Assignee: Olympus CorporationInventors: Ghobad Heidari-Bateni, Khawza Iftekhar-Uddin Ahmed

Patent number: 7920504Abstract: According to various embodiments of the invention a device can announce broadcast traffic in a global access period. Thus, a destination can change its local communication window every global access period. By announcing a local communication window during a global access period it can be more likely that a source device in a network will receive the information because all devices should be active during the global access period. A device can awaken for its local communication window and during the local communication window a source device can schedule a transmission and transmit information to the device.Type: GrantFiled: February 6, 2007Date of Patent: April 5, 2011Assignee: Olympus CorporationInventors: Alaa Muqattash, Ghobad Heidari-Bateni

Patent number: 7912081Abstract: Approaches scheduling and allocation of communication bandwidth across a communication channel provide the opportunity for improved network utilization. A network device is configured to allocating its bandwidth utilization within a communication network, wherein bandwidth allocation is governed by a utilization policy. The network device conducts communication activities within the communication network. When the network device deviates from the utilization policy in scheduling or conducting network activities, a penalty can be imposed on the network device for deviating from the utilization policy. Where one or more network conditions exceed predetermined tolerance levels, the offending network device can be required to reallocate its scheduled activities.Type: GrantFiled: March 23, 2006Date of Patent: March 22, 2011Assignee: Olympus CorporationInventors: Ghobad Heidari-Bateni, Stanislaw Czaja
