Patent number: 7822106Abstract: A rake architecture for a frequency division duplex (FDD) and use also in TDD and TD-SCDMA type communications system, designed to significantly reduce the memory capacity required and thereby also reduce an area on the die of an application specific integrated circuit (ASIC) into which the memory is integrated. A single circular buffer, preferably of the shared memory type is shared by all of the rake fingers of a rake receiver to significantly reduce the hardware and software required to time align multipath signals received by a UE from a base station. This unique time alignment technique also reduces the number of code generators required to track a plurality (typically three) of base stations.Type: GrantFiled: March 4, 2004Date of Patent: October 26, 2010Assignee: InterDigital Technology CorporationInventor: William C.

Patent number: 7630690Abstract: A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna for receiving signals from users and a pool of reconfigurable correlators. Each correlator correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller provides to an input of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor sorts output energy levels of the correlators.Type: GrantFiled: April 11, 2003Date of Patent: December 8, 2009Assignee: InterDigital Technology Corp.Inventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.

Patent number: 7092432Abstract: A Node-B/base station receiver comprises at least one antenna for receiving signals. Each finger of a pool of reconfigurable Rake fingers recovers a multipath component of a user and is assigned a code of the user, a code phase of the multipath component and an antenna of the at least one antenna. An antenna/Rake finger pool interface provides each finger of the Rake pool an output of the antenna assigned to that Rake finger. A combiner combines the recovered multipath components for a user to produce data of the user.Type: GrantFiled: May 4, 2004Date of Patent: August 15, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghius, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward Hepler, Michael Koch, William C.

Patent number: 7082286Abstract: A Node-B/base station has a path searcher and at least one antenna for receiving signals from users. The path searcher comprises a set of correlators. Each correlator correlates an inputted user code with an inputted antenna output of the at least one antenna. An antenna controller selectively couples any output of the at least one antenna to an input of each correlator of the set of correlators. A code phase controller selects a user code for input into the set of correlators. Each delay of a series of delays delays the selected user code by a predetermined amount and each correlator of the set of correlators receives a different code phase delay of the selected user code. A sorter and path selector sorts the output energy levels of each correlator of the sets of correlators and produces a path profile for a user based on the sorted output energy levels.Type: GrantFiled: April 11, 2003Date of Patent: July 25, 2006Assignee: InterDigital Technology CorporationInventors: John David Kaewell, Jr., Timothy Berghuis, Jan Meyer, Peter Bohnhoff, Alexander Reznik, Edward L.

Patent number: 4218233Abstract: The present invention encompasses a method for reducing offensive odors in poultry houses comprising adding at least 10 pounds of composted cow manure per ton of poultry manure. The method of the present invention substantially reduces offensive odor in poultry houses especially ammonia odor and thereby provides a healthier environment for poultry and poultry workers. Since the ammonia loss to the environment is reduced, the nitrogen is retained in the poultry manure providing a product with higher nitrogen content.Type: GrantFiled: August 9, 1976Date of Patent: August 19, 1980Assignee: G.
