摘要： A multiple carrier adaptive notch filter (ANF) module selectively filters a received wideband communication signal to eliminate narrowband interference that lies within the frequency spectrum of the wideband communication signal. To determine the presence of narrowband interference, the multiple carrier ANF module scans various known narrowband channels that lie within the frequency spectrum of the wideband communication signal and determines signal strengths for each of the narrowband channels. The signal strengths from the narrowband channels are compared to a threshold that is derived from a statistical combination of the narrowband signal strengths. Narrowband channels having signal strengths that are greater than the threshold are determined to have interference.

摘要： A tail section for a carpet stretching tool. The carpet stretching tool is the type having a carpet engaging head, an elongate body, a tail section and a lever mechanism allowing extension of the elongate body. The tail section includes a first leg and a second leg, each leg having a wall running face. The legs may be selectively positioned between at least two positions. In one positions the wall running faces form a substantially flat surface allowing use of the tool down a wall section. In a second position the wall running faces on the first and second leg of the tool may be positioned at an angle to allow the tool to be used on corner locations within a room or on a post.

摘要： An undercut saw including a housing, a motor within said housing, a drive shaft rotated by said motor, and a blade mount mechanically linked to said shaft such that a circular saw blade mounted on said mount is rotated when the motor rotates the drive shaft. A fixed blade guard circumscribes a portion of the blade and allows selectable height adjustment of the blade. A stabilization bar on the fixed blade guard may be extended to make the device more stable. On the underside of the fixed blade guard a dust channel allows dust to be swept by the rotating blade into a dust port. The dust channel allows positioning of the dust port away from the leading edges of the fixed blade guard.
