Abstract: ABSTRACT OF THE DISCLOSURE         The reflected signal of a microwave or ultrasonic Doppler intrusion detector is split into two different channels, each containing a mixer for hetrodyning the received signal with a reference signal.  The reference signal for one mixer is the transmitted signal, while the reference signal for the other mixer is the transmitted signal with a phase shift.  Thus the outputs of the mixers are of the same frequency but different phase.  A phase comparator produces two mutually exclusive pulse trains as a function of the outputs of the two mixers, one said output representing motion toward the detector and the other representing motion away from the detector.  These pulse trains are applied through a bidirectional counter to upper and lower limit sensors.  An alarm circuit is activated if either limit is exceeded, thus providing an alarm in response to sufficient motion in either direction.     .

Abstract: ABSTRACT OF THE DISCLOSURE  An apparatus for edging the periphery of an article, such as an ophthalmic lens to a predetermined outline or edge configuration, is characterized by a work holder for supporting and rotating a lens while moving an edge of the lens against a cylindrical grinding wheel.  During grinding, the lens is engaged with only a portion of the grinding wheel, and to prevent a groove from being formed in the wheel successive lenses are automatically and periodically engaged with different portions of the wheel.  In consequence, the wheel wears evenly, it retains a substantially cylindrical shape, all portions of its grinding surface are effectively used in grinding lenses, and the formation of a groove in its surface is prevented, whereby the wheel does not require retruing or reshaping and its useful life is significantly increased.
