Abstract: A noise estimator for threshold correction of a receiver includes a low pass fitter to remove wideband noise from an input signal that includes a signal component and a noise component. The output of the wideband filter is applied to a square-law power detector having an output applied to an envelope detector. The output of the envelope detector is the instantaneous envelope of the input signal and is applied to a low pass filter to perform time averaging and is also applied to a differential network. The output of the low pass filter is a signal representing a time averaged statistical envelope representing the statistical mean of the instantaneous envelope of the input signal. This signal is also applied to the differential network that generates a signal representing the difference in the instantaneous envelope of the input signal and the time averaged statistical envelope signal. This difference signal is applied to a square-law power detector and then to a low pass filter for time averaging. An output of the low pass filter is a signal representing an estimate of the noise component of the input signal.

Abstract: A temporary fastener (10) that fastens two adjacent workpieces (40, 42). The fastener includes a shank (12) that extends through a hole of the workpieces (40, 42). Extending from one end of the shank is a conical shaped head (20).  The fastener also contains a pull stem which has a head (28) located adjacent to the blind end of the shank. The stem head (28) is pulled through the shank (12) to expand and tightly fasten the shank (12) to the workpieces (40, 42).  The fastener is removed by drilling through the head and the shank. The diameter of the conical shank head is smaller than the diameter of the drill bit (54) so that part of the head (20) does not become attached to the drill bit and scratch the workpiece (40). The conical shape of the head also reduces the volume of the fastener material to further reduce the size and amount of chips produced during the drilling process. The tightly engaged shank prevents the fastener from rotating during the drilling operation.
