Abstract: Multi-system or "universal" AM stereo receivers are provided which require no switching of the receiver's stereo decoder circuitry regardless of which AM stereo system signal is being received.  In accordance with one aspect of the invention, acceptable stereo sound is achieved for all AM stereo systems by introducing a selected amount of distortion correction in the L-R channel of the universal receiver and a selected phase difference between the L+R and L-R channels.  In addition, perceived stereo separation in AM stereo and other stereo receivers is enhanced by also properly selecting the gain in the L-R channel in relation to the L+R channel.

Granted: 1993-07-20
Abstract: ABSTRACT        A system is disclosed for positive identification between a patient and a blood unit to be administered to the patient incorporating a combination lock which positively prevents access to the blood unit unless its code matches that of the patient.  An alphabetic code is assigned to the patient and is set into the combination lock at the time the blood unit is removed from the blood bank.  Setting of the code is achieved by the technician without necessity of external tools or mechanical skill.  The combination lock has several alphabetic coded indicia dials which may be set at any orientation with respect to several locking rings. Once the combination is set, a manual clamping force exerted on the structure serves to lock the indicia rings to the associated locking ring to set the code.

Abstract: Abstract This invention describes a method and apparatus for measuring a voltage waveform of an electrical signal on an electrical conductor. A signal is generated on the conductor, and a crystal is positioned over or on the conductor. A polarized light beam is directed through the crystal along a direction essentially perpendicular to the conductor. Birefringence is induced in the crystal, and the polarization of the beam is modulated in response essentially to only those components of the electrical field generated by the signal that are perpendicular to the conductor. The final step involves detecting the modulated polarization of the beam to generate a voltage waveform corresponding to that on the conductor.
