Title: Variable bandwidth filter for narrowband noise reduction and adjustable delay unit
Inventor: CICCARELLI STEVEN
IPC: H03H17/02
Filed: 2005-11-17
Abstract: A technique for noise reduction in a wireless communication system uses controllable bandwidth filters (120) to filter a received signal. In a typical implementation, the filters (120) are used at baseband frequencies. A  measurement (RSSI) is indicative of the strength of the received signal. A  control circuit (144) generates a control signal (146) to control the bandwidth of the filters (120). If the received signal strength is above a first threshold, a wider bandwidth may be used for the filters (120). If the received signal is below a second threshold, the control circuit (144) generates the control signal (146) to set the filters (120) to a more narrow bandwidth. The bandwidth of the filter is also varied depending on the presence of a narrowband interferer (jammer). An adjustable delay unit ensures a constant group delay between all possible configurations of the filter.

Title: Method and apparatus for harvesting and picking up sod
Inventor: MILWAIN ROBERT
IPC: A01G1/12
Filed: 2006-02-01
Abstract: A sod harvester cuts several side-by-side strips of sod, preferably of total width equal to the width of a pallet, and directs the strips up three sets of conveyors arranged in sequence. The first conveyor set runs at or near ground speed; the second conveyor set runs at about double ground speed, and the third conveyor set runs at about triple ground speed. This creates a spatial and time gap between the trailing edges of a set of sod strips on the third conveyor and the leading edges of the next set of sod strips behind them on the second conveyor. The time gap is sufficient to stop the sod strips on the third conveyor and then pick them up and stack them on a pallet.
Patent CA-2597128-A1 (CA)
Title: Frequency layer dispersion
Inventor: CHARLES ALEXANDER GRAHAM
IPC: H04W48/16
Filed: 2006-02-08
Abstract: User Equipment (UE) in receipt of a session start signal indicating a session frequency to use for a session along with other user equipment uses the session frequency until a session stop message is received and then changes to a frequency selected to avoid subsequent use of a same frequency used by the other user equipment. For instance, when the UE receives a Multimedia Broadcast Multicast Service (MBMS) session start signal and it contains a preferred frequency, the Radio Resource Control (RRC) layer of the UE could store the frequency of the serving cell for later reference. The UE then converges to the preferred frequency for the duration of the session. When the UE receives a session stop, RRC layer retrieves the previously stored information about the pre-session frequency and requests the physical layer (L1) to select a cell on the frequency where it was previously camped on.
